【1】E 根據(jù)下一句Green tea can be absorbed by the body easily into a form of vitamin A, which helps reduce radiation. _綠茶很容易就被人體吸收，并形成維他命A，維他命A可以幫助減少輻射�？芍径谓榻B的抵抗輻射的方法是喝綠茶。故E項(xiàng)正確。

【2】G 在前句Green tea can be absorbed by the body easily into a form of vitamin A, which helps reduce radiation. 敘述了綠茶的一大作用就是被人體吸收形成維他命A，維A可以抗輻射，也可以提高我們的視力。所以G項(xiàng)敘述的是喝綠茶的另外一個(gè)好處。

【3】A 根據(jù)下一句The brighter the screen the higher the radiation there will be and vice versa.可知電腦屏幕越亮，輻射越厲害，也就是說要調(diào)整電腦屏幕的亮度。故A正確。

【4】B 根據(jù)前一句Make sure you do a skincare protection before sitting in front of the computer.可知本段講述的是保護(hù)臉部，那么B項(xiàng)Apply a layer of facial mask to protect yourself.敷一層面膜保護(hù)自己符合段落大意。

【5】 F 根據(jù)本段Old computer in general, has one to two times more radiations released than the new one within the same distance.可知舊電腦的輻射是新電腦的兩倍，那么為了減少輻射，最好是換用新電腦。故F項(xiàng)正確。

【題目】In Vietnam, two members of a family of street vendors are finding a way to help the poorest students in Hanoi. Pham Minh Dap and his brother are providing the students with mostly free English and Japanese lessons at a learning center they created. The men want to help people who would not normally have a chance to learn a foreign language.

Some education experts in Vietnam say such knowledge may help college graduates get jobs. The country’s economy has improved. But many graduates continue to have a hard time finding employment. Local media reported ten percent of university graduates do not have a job.

Earlier this year, 24-year-old Pham Minh Dap and his brother established a school they call “Stand By You”. Volunteers teach poor students English and Japanese. Many classes are free. Students with some language knowledge pay 25 to 50 cents per class. Mr. Dap pays about $ 500 to rent the language center space and for other costs. He gives about $ 150 from his earnings as a street Vendor and private language teaching. His brother gives the same amount from the money he earns as a secretary. Friends provide the rest. Mr. Dap and many of his family members have sold things outside HoaBinh Park in the center of Vietnam’s capital for five years. They come from a village of rice farmers in Thanh Hoa Province.

Twenty-four-year-old Pham THi Trang is one of 600 students at the language school. She is finishing her university studies. Her parents work in a market in a village in Ha Nam Province. She says life is hard in the city. She earns about $50 a month from a part-time job, and her parents give her $ 75. But this is not enough to live on. She has said she has to be very careful with money so she can pay her bills.

Demand for the school is growing. About 1,000 people are on a waiting list to enter. Ten people have offered to teach for free. And Mr. Dap says he is hoping to raise money to pay for a bigger place. He wants to open more classes.

【1】“Stand By You” is established____________.

A. by the Vietnam government B. by a family

C. by a non-profit organization D. by two brothers

【2】What can we infer from the passage?

A. All the courses provided by “ Stand By You” are free.

B. Farmers in Vietnam are very rich.

C. “Stand By You” is especially welcomed by the poor students in Vietnam.

D. Only ten percent of university graduates in Vietnam are employed.

【3】 Mr. Dap wants to pay for a bigger place because___________.

A. he wants to make more money.

B. he wants to open more classes for poor students.

C. he wants to change his job.

D. he wants to provide a wider space for students to play.

【4】The main idea of the passage is ____________.

B. the demand for school is growing in Vietnam.

C. free learning of English and Japanese are provided in Vietnam.

D. students in Vietnam are very poor.

【題目】As weather cools across the United States, a growing number of Americans visit farms. They harvest fruits, enjoy hay wagon rides and walk in the fields. These people are called “agri-tourists.” They improve the economy of rural areas and help farmers increase their profits.

School children are walking in a corn field maze. The corn is cut into tricky passageways that make it difficult to find a way out. The children are from Yorktown Elementary School in Bowie Maryland. They have traveled to Montpelier Farms in Prince George’s County which is also in Maryland. The farm is about 40 kilometers from The White House.

Debbie Pierson is the student’s teacher. “We go on these kind of field trips so that the children will have a hands-on experience of what it’s like to be on a farm,” Pierson said.

In Loudoun County Virginia, there are farms where grapes are grown for use in making wine. Many of the farms let people visit, and drink the wine that is made there. Bill Hatch owns the Zephaniah Farm Vineyard. He holds wine tastings in his home. “We are doubling the number of visitors to our farm every year. We have an average of 250 people on a weekend,” Hatch said.

As more people visit farms, more farmers are adding activities in which visitors can take part.

Malcolm Baldwin owns WeatherLea Farm and Vineyard in Loudoun County. Six years ago, he began letting people be married at his farm. They can also sleep at the farm overnight. Mr. Baldwin says the money he makes from these activities let him keep his small farm operating. “But without the animals, and without the vines, the wedding business wouldn’t be as profitable (有利可圖的), because people like to see the vines. They like to see the animals and without which I don’t think this will be a popular place,” Baldwin said.

【1】We can infer from the first paragraph that people always go for field trips in _______.

A. Spring B. Summer C. Autumn D. Winter

【2】The underlined word “maze” in the passage is similar to “_______”.

A. puzzle B. trip C. house D. activity

【3】 On Malcolm Baldwin’s farms, visitors can ________.

A. taste the wine made in the USA

B. raise and hunt animals

C. do wedding business

D. have fun as well as bring him money

【題目】Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation. It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York，So I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.

I've made living looking for the best deals and exposing （揭露） the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.

I tell you this because there is no shame in getting your money’s worth. I’m also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.

【1】Why did Delta give the author's family credits?

A. They took a later flight.

B. They had early bookings.

C. Their flight had been delayed.

D. Their flight had been cancelled.

【2】What can we learn about the author?

A. She rarely misses a good deal.

B. She seldom makes a compromise.

C. She is very strict with her children.

D. She is interested in cheap products.

【3】What does the author do?

A. She's a teacher. B. She's a housewife.

C. She's a media person. D. She's a businesswoman.

【4】What does the author want to tell us?

A. How to expose bad tricks.

B. How to reserve airline seats.

C. How to spend money wisely.

D. How to make a business deal.

My parents decided try a new Western restaurant last weekend, so I went with them. The evening started well and the menu looks good. I had soup with my starter but the waiter didn't bring a spoon so it was getting a bit cold after I could eat it. Then, for our main course, I had a piece of beef. Besides, I couldn't cut the beef because of my knife wasn't very good. For my dessert I had a apple pie but I didn't have a fork or a spoon so I ate them with my fingers! What a terribly experience!

【題目】On January 11, 2007, as students sat and listened, a very important guest speaker named Richard, spoke to the students in the lecture hall. He not only showed the potential（潛能）within young adults, but encouraged them to work hard at their lessons.

Richard was a young child when his mother died and his father walked out. He was forced into many different foster homes（寄養(yǎng)家庭）where he felt unhappy. He did not know that his life was taking a turn for the worst.

His uncle, after getting out of prison, got him into drugs and alcohol. His uncle taught him that his place in life was either to be in prison or die trying to be “a man.” His uncle’s teaching almost started affecting him until a very important person came into his life: a teacher. This teacher taught him there is a place in the world for everyone and it isn’t related to drugs.

Richard is now a Harvard University graduate and has a great and loving family. Why? He was taught to have respect not only for others, but for himself.

After the meeting, it was hoped that the students realized within them there is a potential, and within everyone around them, is knowledge. As Richard reminded them, “Knowledge is power.”
