I know what you’re thinking: pizza?For breakfast? But the truth is that you can have last night’s leftovers in the a.m. if you want to.

I know lots of women who skip breakfast (不吃早飯), and they have a ton of different excuses for doing it. Some say they don’t have time, others think they’re “saying” calories ,still others just don’t like breakfast food .

But the bottom line is that eating in the morning is very important when you’re trying to lose weight . “Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R.D,who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.

Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.

So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers – it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow.” I put away the leftovers instead of eating more that night. Try it … you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects.

1.The word “l(fā)eftovers” in paragraph I probably means ______.

A. food remaining after a meal B. things left undone

C. meals made of vegetables D. pizza topped with fruit

2.What can we infer from the text?

A. Working women usually have breakfast in a hurry.

B. Many people have wrong ideas about breakfast.

C. There are some easy ways of cooking a meal.

D. Eating vegetables helps save energy.

3.According to the last paragraph, it is important to _______.

A. eat something for breakfast

B. be careful about what you eat

C. heat up food before eating it

D. eat calorie-controlled food

4.The text is written mainly for those _______.

A. who go to work early B. who want to lose weight

C. who stay up late D. who eat before sleep

For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.

◆Get a group of friends together and go exploring. You'll need a good map, a compass, a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies. Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

◆See if your school or a club organizes orienteering(越野識途比賽) activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it’s not only good fun, but also a great way to keep fit.

1.When you sit beside the driver, you’d better ________.

A.look ahead to see where there is a gas station

B.move to the back seat if feeling uncomfortable

C.keep looking at the map to find another place to go to

D.direct the driver when necessary

2.In the exploration, why do you need wait for the slower friends?

A.To share the fun with him/her in exploration.

B.To tell him/her what’s going on with group members.

C.To avoid yourself or your friends getting lost.

D.To show them how fast you can go.

When Russell Lyons volunteered for the first time, he read “Goodnight Moon” to a class of San Diego preschoolers. And it wasn’t reading — he’d memorized the book and was reciting it out loud. He was 4. Still, he said it felt good there, in front of the other kids, lending a hand. He wanted more of that feeling.

Thirteen years later, he’s getting a lot of it. He’s on a five-month road trip across America — not sightseeing, but volunteering.

The University City resident has spent time at an animal reserve in Utah, a women’s shelter in St. Louis, a soup kitchen in New York, a retirement home in Tucson. This week he’s in Los Angeles, at a program that supports disabled youth.

“I just like helping people and feeling that something I do is making a difference,” he said. He resists the idea that his “Do Good Adventure” is all that unusual. It bothers him that the media often describe young people as lazy, self-centered. So he sees his trip as a chance to make a statement, too. “About 55 percent of teens do volunteer work, higher than the rate for adults” he said, according to a 2002 study. “Not everybody knows that. ”

Of course, some teens do volunteer work because it looks impressive on their college applications. Lyons said he mentioned his trip on his applications. But charity work is a habit with him. Even before the cross country trip, he was volunteering about 200 hours a year at various places. He’s made sandwiches for homeless families in Washington D.C. He’s taught math to fifth-graders in Cuernavaca, Mexico.

He gets some of that drive from his mother, Lesley Lyons, who has been involved in nonprofits for much of her life. She was there when her son “read” to the preschoolers — a memory of hers “that will never go away.”

1.What did Russell Lyons think of his first volunteering?

A. Creative.B. Impressive. C. Persuasive. D. Imaginative.

2. The third paragraph is meant to________.

A. show Russell Lyons is working as a volunteer

B. introduce some tourist attractions across America

C. call on volunteers to offer help to those in need

D. show volunteers are needed in all parts of America

3. According to Paragraph 4,Russell Lyons is against the idea that____.

A. what he has done is common

B. most teens do volunteer work

C. young people don’t work hard

D. adults prefer to be volunteers

4. Russell Lyons has been doing volunteer work because_______.

A. it is necessary for college applications

B. he ought to keep his promise to Mom

C. he likes the feeling of being praised

D. it has become a natural part of his life

5.What does the last paragraph suggest?

A. Lesley Lyons is too busy to look after her son.

B. Russell Lyons is greatly influenced by his mother.

C. Lesley Lyons almost earns no money all her life.

D. Children are always important to their parents.

Last Christmas, when I was in the fourth grade and my brother was in the first grade, our school held its yearly Holiday Shop. At the Holiday Shop students can buy things like necklaces, key chains, and other small items for their friends and family as Christmas gifts. Since my brother really wanted to take part, my mom gave him two dollars to buy his Christmas gifts.

My mom didn’t know that he had picked out a special necklace for her. When he got home from the Holiday Shop that day, he couldn’t wait to show it to me. He pulled out a little green box and opened it. Inside was a gold chain with a little red flower and a man-made diamond next to gold letters that spelled out,“Grandmother”.

“Wow,” I said.“It’s beautiful.” Since my brother was in the first grade and was just learning to read, he didn’t realize that the necklace said “Grandmother” instead of “Mother”. I knew that on Christmas morning, when he found out he had bought the wrong necklace, he would be very unhappy, so I said nothing more about it. My brother ran and put the necklace under his bed to hide it from Mom until Christmas morning.

When he wasn’t looking, I took the necklace and put it in my backpack. The next day I took it back to school and asked the woman who ran the Holiday Shop if I could change it for the “Mother” necklace. She said yes. When I got home that day, I put the necklace under my brother’s bed.

When my mom opened it up on Christmas morning, my brother was so exalted! My mom’s eyes were filled with joy. She knew what had happened, which made the necklace even more special to her!

My brother still does not know what I did, but I knew I had done the right thing.

1.What do we know about the gift the author’s brother bought

根據短文內容,從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

It is hard to know what babies want. They can’t talk, walk, or even point at what they’re thinking about. 1. And, compared to adults, they develop these skills quickly. People have a hard time learning new languages as they grow older, but infants have the ability to learn any language easily.

For a long time, scientists have tried to explain how such young children can learn complicated(復雜的) grammatical rules and sounds of a language. 2. This new information might eventually help kids with learning problems as well as adults who want to learn new languages. It might even help scientists who are trying to design computers that can communicate like people do.

Most babies go “goo goo” and “ma ma” by 6 months of age. 3. For decades, scientists have wondered how the brains of young children figure out how to communicate using language. With the help from new technologies and research strategies, scientists are now finding that babies begin life with the ability to learn any language.

They get into contact with other people, listen to what they say and watch their movements very closely. 4. Studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world.

There are about 6,000 sounds that are spoken in languages around the globe, but not every language uses every sound. For example, while the Swedish language has 16 vowel sounds, English uses 8 vowel sounds, and Japanese uses just 5. Adults can hear only the sounds used in the languages they speak fluently. To a native Japanese speaker, for example, the letters R and L sound the same. 5.

A. Children don’t respond to this kind of sound.

B. Most children speak in full sentences by age 3.

C. A baby’s brain focuses on the most common sounds.

D. That is why they quickly master the languages they hear often.

E. So a Japanese speaker cannot tell “row” from “l(fā)ow”, or “rake” from “l(fā)ake”.

F. Yet newborns begin to develop language skills long before they begin speaking.

G. Now, researchers are knowing about what’s happening in the brains of the youngest language learners.

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(風車) began to be used in ancient Iran back in the 7th century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind(磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote(偏遠的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available(可利用的) to people in almost all areas of the United States, windmills were seldom used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

1.From the text we know that windmills__________.

A. were invented by European armies

B. used to supply power to radio in remote areas

C. have a history of more than 2,800 years

D. have rarely been used since electricity was discovered

2.What was a new use for wind power in the late 19th century?

A. Producing electricity.

B. Sailing a boat.

C. Grinding wheat into flour.

D. Pumping water from ground.

3.One of the reasons wind was rediscovered in the 1970s is that______.

A. the supply of coal and gas failed to meet needs

B. it is one of the oldest power sources

C. it was cheaper to create energy from wind

D. wind power is cleaner

4.The passage is mainly about______________.

A. the global pollution from burning coal and gas

B. the worldwide movement to save energy

C. the history of using wind power

D. the advantages of windmills
