Everyone wants to have a healthy heart. Still, heart diseases affect more than 1 in 3 adults in the United States. The good news is that some simple, everyday habits can make a big difference in your ability to live a healthy lifestyle. Here are some worst habits for your heart, and how to avoid them.
Watching TV
Sitting for hours on end increases your risk of heart attack and stroke(中風(fēng)),“some exercise doesn’t make up for the time you sit,”says Harmony R. Reynolds, Why? The lack of movement may affect blood levels of fats and sugars. Dr. Reynolds advises walking around regularly and, if you’re at work, standing up to talk on the phone.
Leaving hostility and depression unchecked
Are you feeling stressed or sad? It can do harm to your heart. While everyone feels this way some of the time, how you handle these emotions can affect your heart health.“Those with stress are in greater danger; research has shown a benefit to laughter and social support,” Dr. Reynolds says. “And it’s helpful to be able to go to someone and talk about your problems.”
Cutting off from the world
It's no secret that on some days, other human beings can seem annoying and too difficult to get along with.
However, it makes sense to strengthen your connections to the ones you actually like. People with stronger connections to family, friends, and society in general tend to live longer, healthier lives.
Everyone needs alone time, but you should still reach out to others and keep in touch whenever you can.
Drinking (too much) alcohol
Sure, studies suggest a small amount of alcohol may be good for your heart. However, too many of us drink over. Too much alcohol is linked to a greater risk of high blood pressure, high levels of blood fats, and heart failure.
小題1:Watching TV for a long time may ______________.
A．help you live a healthy lifeB．lead to heart attack
C．make up for the time you sitD．make you feel stressed
小題2:Which of the following is bad for those with stress and sadness?
A．Laughing a lotB．Talking about their own problems.
C．Getting social supportD．Leaving these emotions alone.
小題3:If you want a long healthy life, you should____________.
A．cut off from the worldB．get along well with others
C．stay alone as much as possible D．drink no alcohol
小題4:From the passage we can infer that _____________.
A．some everyday habits can help avoid heart attacks
B．standing up to talk on the phone is not a good idea
C．it’s easy to strengthen your connections to others
D．too much alcohol is not linked to heart failure

My interest in Chinese food started years a90, when l was a young reporter for the Washington Post. Our office wasn’t far from Chinatown, where I found some very good Chinese restaurants．
The first time I ever ate Chinese food I loved it. I noticed the fresh taste of the meat and vegetables. When I learned more about the food, I began to understand why it has this special feature.
Many years ago, China had an energy crisis because it lost much of its wood due to over population and poor management of its forests. This loss was very bad for the country, of course, but it turned out to be very good for the food. Wood became very expensive and hard to get，so the Chinese had to either find a substitute for their valuable wood，or learn how to use it better. There weren’t any substitutes so people found ways to economize.
In order to economize in cookin9, they had to use very little wood. So they started cutting their meat and vegetables into small pieces before they put them in the hot oil．That way，the food cooked faster and they saved their fuel. The food prepared in this way kept its fresh flavor一and it's this flavor that attracts people from other countries to the art of Chinese cooking.
小題1:This text is mainly about________.
A．what caused Chinese food to taste fresh
B．how Chinese food is cooked in the US
C．when the author started to make Chinese food
D．why most foreigners like cooking Chinese food
小題2:The author mentioned the energy crisis to show________.
A．it is important to protect the forests
B．it is necessary to find substitutes for wood
C．why the Chinese changed their way of cooking
D．what problems a big population is causing China today
小題3:It can be inferred from the text that before the energy crisis Chinese food________.
A．was cooked in rather large pieces
B．was cooked in water but not oil
C．didn’t taste good
D．didn’t look fresh

Don't you just love ice skating every winter? I am sure, that since winter is approaching, your skates are set to come out, just waiting to be used. Impress your friends with your new trick on how to ice-skate backwards with the help of these tips. Skating backwards on ice is a bit difficult but once you master the basic, there' s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.     
Stand Straight
The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don't worry; this happens to all.
Confidence is What You Need
The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice. Just practice rolling backwards down a gentle slope every single day or just by pushing off from a wall or something of that sort. But before you do that, make sure that the place where you are practicing is free from any kind of debris（碎片）because otherwise, you could end up in the hospital due to some accident. While going backwards, just get used to the feeling of moving backwards. One of the important ice skating tips and techniques is that if you feel that you are losing your balance, then scissor (做剪式運(yùn)動(dòng)) your skates. Keep practicing this till you are confident about it.
Maintain Speed
Confident now? Great! Now the next step is to maintain your speed. While rolling in a straight line with one skate, with the other try sculling (滑漿), that is, keep pushing yourself backwards with an outwards stroke (滑動(dòng)). Now bring the skate which you were using to scull, and then again, repeat the same process. Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling. Now, try the same thing using the other foot. Again keep doing this till you are confident enough.
Increase Your Speed Now
Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed. Try some of your own tricks now. Scull with either foot or with both at the same time.
Scull and Be Aware
While you keep one foot straight, keep sculling with the other. You can do that simultaneously with both feet. Concentrate on what you are doing but don't get so involved that you don't see where you are going. If you are not watching your back, you might just bang against something or someone.
小題1:According to the text, confidence comes from ________ .
A．constant exerciseB．strict coachesC．high speedD．good techniques
小題2:Which is the right order of ice-skating backwards?
a. Increasing your speed.                       b .Being able to scull with one foot.
c. Being about to stand straight.                   d. Trying some different tricks.
A．c→a→d→bB．c→b→d→aC．c→b→a→dD．a(chǎn)→c→b→d
小題3: In the last paragraph the author mainly wants to express _________.
A．one must be brave to learn to ice-skate backwards
B．skating and keeping cautious are both important
C．it’s difficult to concentrate when ice-skating backwards
D．it' s a common thing to hit someone when ice skating backwards
小題4:The purpose of the text is _______ .
A．to offer some advice on ice-skating backwards
B．to introduce the culture of ice-skating backwards
C．to explain advantages of ice-skating backwards
D．to compare different ways of ice-skating backwards

Searching for airfares often seems like a game that passengers are bound to lose.
Prices change from day to day, even minute to minute. Looking through multiple websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.
“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog.com.
Harriet Levy paid $179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $215. A few rows back, Ellis and Dianne Traub paid $317 each. There were at least 12 fares on the flight, ranging from $169 to $360.
There’s no reason for it, Harrison said.
Fares can vary significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $755 to $1,143 from a Friday to Saturday in late April, then fell to $718 on Sunday.
The flight was one of a dozen the Associated Press (美國聯(lián)合通訊社)followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.
There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:
● Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.
● Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are highest eight to ten weeks and two to three weeks in advance.
● Make use of social media. Airlines are giving more benefits like exclusive (獨(dú)家) sales to travelers who interact (互動(dòng)) with them on Twitter and Facebook. Those specials are often gone within hours.
● The so-called discount airlines – JetBlue, Air-Tran, Southwest and Frontier – adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.
小題1: What can we infer from the first sentence of the text?
A．Passengers are unable to search for airfares.
B．Airlines often play games with passengers.
C．Airfares are set in different situations.
D．It’s difficult for passengers to get the best price.
小題2:The underlined phrase “pull the trigger” in Paragraph 3 probably means _______.   
A．startsearchingB．getthehighestprice
C．makeapurchaseD．getonboardtheplane
小題3:By using a lot of figures, the author intends to _______.
A．show there is standard price for every single airline
B．discover the rules behind airfares
C．guarantee passengers a low price
D．prove airfares can vary widely
小題4:Passengers are advised to book flights _______.
A．in the middle of the week
B．on special websites
C．several months before traveling
D．with airlines which are famous for offering discount prices

Fans of US television dramas watch their favorite series for different reasons: some want to improve their English skills, others just want to kill time.
Some TV series are more than pure entertainment―they have a certain depth. Mad Men, which returned with a sixth season recently; Monday Mornings, which just finished its first season; and Modern Family, which sweeps the awards every year, are just a few examples.
Why do these shows stand out among so many similar ones? TV critics Raymond Zhou will give you an idea of why some shows are better than others.
Period drama—More than time travel
Period dramas are intended to capture the ambience (氣氛) of a particular era. Directors must therefore attract audiences as much by their recreation of a historical setting as by an interesting storyline.
Mad Men is an excellent example of this balance being struck. Set in New York during the 1960s, it accurately shows US attitudes in the workplace through the alcoholism and chain-smoking common of the time, and places an absorbing plot right in its center.
But rather than merely presenting a past decade, Mad Men’s subtle (微妙的) description of the struggles of white-collar workers at the time, both male and female, makes it stand out.
“The series’ attention to detail is superb,” Raymond Zhou said. “For example, creator Matthew Weiner makes Don Draper―the leading role of the series―drive a Buick instead of a Cadillac, because Weiner thinks the ad man lacks the self-pride to buy a luxury car. It’s this kind of attentiveness that raises the show’s artistic value.”
Critics also recommend
Another period drama that works is Broadwalk Empire, set during the prohibition period of the 1920s and 1930s in Atlantic City, New Jersey.
Heather Havrilesky at Salon magazine noted how the show “revels in the oddities(怪事) of its time, peeling back the layers of polite society to reveal a shadow world of criminals and politicians working together to keep the liquor flowing.”
Why does it appeal to viewers? Because they know that the “l(fā)iquor” is a metaphor (暗喻) for today’s political scandals (丑聞).
小題1: How many US TV series are mentioned in this passage?
A．One.B．Two.C．Three.D．Four.
小題2: The following statements are the reasons why many people are attracted by US television dramas EXCEPT that __________.
A．US television dramas merely present a past decade
B．directors recreate a historical setting and adopt interesting storylines
C．the dramas can improve their English skills, and help people kill time
D．some TV series are more than pure entertainment, and they have a certain depth
小題3: According to Raymond Zhou, Don Draper’s driving a Buick instead of a Cadillac shows __________.
A．Mad Men attaches much importance to details
B．Mad Men places an absorbing plot right in its center
C．the director wants to raise the show’s artistic value
D．Mad Men’s description of the struggling white-collar workers makes it stand out
小題4: What does the passage mainly talk about?
A．Directors of US dramas.B．US dramas and their storylines.
C．US period dramas to kill time.D．US dramas and their magic touch.

Peer pressure can be a powerful force, and sometimes a positive one. For example, hanging out with active peers may lead kids to       more, making a child’s social network a vehicle for promoting healthy habits and        obesity unconsciously.
The scientists studied networks of a group of students aged 5 to 12 and       how the youngsters’ made and dropped friends, and        effect these changing relationships had on their physical activity level.
In fact, children        their exercise level little by little to better      those in their circle; children who    with more active students were more       to increase their physical activity levels,        those who befriended more sedentary(久坐不動(dòng)的) children became        active. The children were mirroring, following or adjusting to be        to their friends before they knew it.
The encouraging        suggest a potentially effective way to change children’s behavior.        relying only on organized exercise programs to get moving, perhaps introducing sedentary kids to more active ones — might help more kids        the couch.
It’s believed that this is a possible novel approach to obesity       . The social environment does carry more power than we have given it        for, so we should make use of that intentionally to influence kids.

This year some twenty-three hundred teenagers (young people aged from 13 to 19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world．
Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America．
Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. Schools were completely different from what he had expected—much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.
Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual(個(gè)人). Fred found the food too simple at first. Also, he missed having a car.
“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”
At the same time, In America, Mike, a friendly German boy, was also forming his idea．“I suppose I should criticize(批評(píng)) American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens(公民). There ought to be some middle ground between the two.
小題1:The world exchange programme is mainly to ________.
A．help teenagers in other countries know the real America
B．send students in America to travel in Germany
C．have teenagers learn new languages
D．let students learn something about other countries
小題2:Fred and Mike agreed that ________.
A．American food tastes better than German food．
B．Americans and Germans were both friendly
C．German schools were harder than American schools
D．There were more cars on the streets in America
小題3:What is special in American schools is that ________.
A．there is some middle ground between the two teaching buildings
B．students go outside to enjoy themselves in a car
C．students usually take fourteen subjects in all
D．there are a lot of after-school activities
小題4:After experiencing the American school life, Mike thought _________.
A．German schools trained students to be better citizens
B．A better education should include something good from both America and Germany
C．American schools were not as good as German schools

How do you think of the following example? Many Japanese never take the vacations they should enjoy, but with the coming of “Golden Week”, several holidays following one after another in late April and early May, they pour out of the country in the tens of thousands.
So when traveling, whether on business or for pleasure, the first thing to think about are hotels. The kind of hotel you choose is decided according to how much money you want to spend. There are small hotels with very few services, where the prices are low, or there are large hotels with all the very latest comforts, where you could spend all the money you have in the bank for a very comfortable night.
There are several different kinds of people who go to hotels. Some want to live, rather than just stay, in a hotel; hotels which are designed to meet their needs are called residential hotels. However, most people who stay in hotels are either business people or tourists on holiday.
In most hotels, there are two kinds of rooms: single rooms, for the use of one person, and double rooms, for the use of two people. In addition, in large hotels, there are also suites (套房), which include two or more rooms connected together — perhaps a bedroom and a living room. They are for people who are very rich or very important.
小題1:From the example of many Japanese, we can learn that           .
A．they don’t enjoy taking vacations because it’s too expensive
B．they enjoy touring in “Golden Week” because it consists of several holidays
C．they don’t have vacations unless they go abroad
D．they enjoy staying at home unless they have enough time and money
小題2:A person’s choice of a particular hotel is made mainly according to           .
A．how much he is willing to pay for a night
B．whether he is traveling on business or for pleasure
C．whether the hotel is in the central part of a city
D．how good the services of the hotel are
小題3:If the president of a certain country comes, he will most probably             .
A．live in a new hotelB．stay in a single room of a hotel
C．stay in a double room of a hotelD．stay in a suite of a modern hotel
小題4:If a person stays in a modern hotel with the latest comforts for a night,           .
A．he will become poor
B．he will have to pay a lot of money
C．he will have to spend all the money he has in the bank
D．he will have to draw all of his money out of the bank
