Think stars don’t move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move—they are just so far away that the movement is hard to see.
But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities(奇特). It was located on the outer edge of the Milky Way, the galaxy(星系) we live in. The star was speeding away like nothing he’d ever seen. “It seemed unbelievable. No star in the galaxy has a speed like that,” Brown remembers. “I thought, oh my goodness, I have something kind of special here.”
No one had ever seen a star like this one. What does a scientist do when the results don’t make sense?
Brown didn’t give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called hypervelocity stars. Hyper means “above” and velocity has to do with speed. He and his team just found six more of these “above speed” stars, bringing to the total of 16. And, he says, he’s found even more, and is just waiting for the scientific community to confirm them.
小題1:In 2005, astronomer Warren Brown found___________.
A.a(chǎn) star was speeding away very fast.
B.a(chǎn) stars was moving away very slowly.

Westerners think that the education ways in many Chinese families are hard to understand. Here are some examples.
Many children in China are looked after by their grandfathers and grandmothers because their parents are busy. But children need to stay and communicate with their parents.
Parents pay no attention to the rights (權利) of children. Parents should knock at the door before they go into the room of their children. (1)They shouldn’t move their children’s things before they agree. Parents should communicate with children and respect (尊重) the rights and decisions of them. Children who are not respected also do not know how to respect others.
(2) Parents often          their children          others. Most Chinese parents want their children to be successful, because it can save the parents’ face. Parents often say “You see somebody else is studying hard, what good grades they have, and what prizes they get”. This is the worst thing. It will only bring the child much harm and pain.
Many children are made to do what their parents expect, though they do not like it. For example, parents ask their children to learn to play the piano or go abroad. It should be decided by children themselves.
The more hard-working, the better. Many parents think school performance is everything. In fact, the integrated(綜合)ability is so important that it will affect children all their lives.
小題1:將(1)句譯成中文。
小題2:在(2)句的空白處分別填入一個適當?shù)脑~使句意完整、上下文通順。
小題3:回答問題:Why are many children looked after by their grandparents in China?

To most of us, school means classes, teachers, schedules, grades, and tests. But for the children at Sudbury Valley School in Massachusetts, school is very different.
Firstly, there are no lessons. All the children, aged between 4 and 19, do whatever they want. There are no teachers, only “staff members (職員)”. The idea behind this is that you do not need to make children learn, because children want to learn anyway. “You do not need to say to a three-year-old. ‘Go explore your environment.’ You can’t stop them!” says Daniel Greenberg, a founder of the school. “But if you make children do what you want all day, they will lose all taste for learning.”
At Sudbury Valley School, you will allow children to talk, read, paint, cook, work on computers, study French, play the piano, climb trees, or just run around. Two boys spent three years just fishing!
The other way that Sudbury Valley School is different is that the children can decide the rules. Every week, there is a school meeting where both children and staff have one vote each — even the four-year-olds. They decide the school rules, how to spend the school budget(預算), and even which staff they want and do not want any more.
When the school first opened in 1968, people said it would never work. But today, the school has 200 students, and 80% of its students go on to college. Even the two boys who went fishing all time have successful careers today. One of them is a musician and the other is a computer scientist.
小題1:What does the school believe?
A.Teachers cannot teach children well.
B.Children learn best when they do what they want to do.
C.Learning is for adults — children should only play.
D.Children should only learn about one thing at a time.
小題2:What does Daniel Greenberg say about three-year-olds?
A.They love learning.
B.They are very naughty.
C.They want to be outside all the time.
D.They are too young to learn anything.
小題3:What happens to the children after they leave this school?
A.They do the same things as children from other schools.
B.They have problems getting into college or getting a job.
C.They usually do very unusual jobs.
D.They are not successful in their business.
小題4:What is the main topic of the article?
A.Children’s hobbies B.Education in the US
C.A school without rulesD.An unusual school

If the rose can be said to be a special flower, then the apple can be said to be a special fruit. It is very important in American culture. American stories speak of Johnny Appleseed, who went throughout America collecting apple seeds and planting apple trees. He had a great love for nature and went through fields and farms adding richness and beauty to the country.
One of the first sayings taught to school children is, “An apple a day keeps the doctor away.” This short saying encourages children to eat fresh fruit to keep healthy. If someone always says good words to a person, people will call him an “apple polisher”. This, however, is not a good name. If someone is very dear to us, we say that he or she is the “apple of our eye”.
Most people believe that the fruit which Eve gave to Adam was an apple, even though the Bible(圣經(jīng)) never says so. The apple, therefore, is a deep part of the language and stories of America.
An apple is also delicious. Apples can be cooked in many ways, used as a dessert, and made into sweet juice.
In many parts of the country during the harvest season, a popular activity is to go into an apple garden to pick apples. Washington, D. C. and New York are both famous for their apples.
Finally, when it’s time to take a vacation to American cities, one can always visit New York, which is “the biggest apple” of all the American cities.
小題1:What does the underlined phrase “apple polisher” mean?
A.Something for cutting apples.
B.A person who likes to please others.
C.A person who is dealing with fruits.
D.A machine for cleaning apples quickly.
小題2:Which of the following is TRUE with apples?
A.Apples are medicine.
B.Apples are the most important food.
C.New York is famous for its big apples.

It seems school children all over the world complain about their school food. Cherie Blair, wife of former British Prime Minister Tony Blair, said that she would prepare a packed lunch for her son if school dinners do not improve. So what do students of your age eat for lunch at school?
Japan
High schools have canteens, which serve everything from noodles to rice, but not burgers and chips. Other children bring food from home such as cold rice balls, meat or fish, pickles(泡菜) and vegetables.
Students take home a menu for the coming month containing notes on nutrition value. Twice a year parents are invited to have a taste of the food. The class with the fewest leftovers(剩飯) at the end of the month receives a prize.
United States
A typical menu from a US school is made up of a hamburger with fried potatoes or roast chicken, lettuce and pickles, fruit and cookies. School lunches must also provide at least one-third of the daily dietary allowances(定量) of protein, vitamin A, vitamin C, iron, calcium and calories.
Australia
Meat pies, sausage rolls and hot dogs are all traditional dishes in Australian school shops. But as the nation pays more attention to children’s health, healthier foods have started to find their way onto school menus.
Many schools have used a traffic light system. The sale of red-labelled foods, including pastries, chocolate and soft drinks, is served only twice a week. Healthier green-labelled foods such as sushi, sandwiches, corn and watermelon, however, are available every day.
In some schools, students have a choice of up to 89 foods to choose from, including popcorn and rice.
South Africa
Most of South Africa’s schools do not serve meals at all. Classes end at 1:30 pm and students get their own lunches. Many students bring food from home, usually sandwiches.
Fast food and fried food sell the best among students, which has led to a rise in obesity among children. But as more people began to realize the fact that being too fat may cause different diseases, some schools in towns have led the way towards better nutrition(營養(yǎng)). Now students at these schools are provided with lunches of porridge with vegetables, such as cabbages, onions, beans, carrots and tomatoes.

I love my iPhone---it’s my little connection to the larger world that can go anywhere with me. I also love my computer, as it stores all of my writing and thoughts. Though I love these devices(裝置) of technology, I know that there are times when I need to move away from them and truly communicate with others.
I teach history in a high school. My goals for the class include a full discussion of historical themes(主題) and ideas. Because I want students to thoroughly study the material and share their ideas with each other in the classroom. I have a rule---no computers, iPads, phones, etc. When students were told my rule before class, some of them were not happy at all.
Most students think that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There’s a bit of truth to that. Some students believe that I am anti-technology. There’s no truth in that at all. I love technology and try to keep up with it so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations. Interruptions(打斷) by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for ideas. I want them to push each other to think differently and to make connections between the course material and the class discussion.
I’ve been teaching my history class in this way for many years and students realize that with deep conversation, they learn at a level that helps them keep the course material beyond the classroom.
I’m not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change. A few hours of technology-free dialogue is just too sweet to give up.
小題1:What’s the second paragraph mainly about?
A.The reasons why students should use computers or iPads in class.
B.The advantages of using cell phones and computers in the classroom.
C.What the writer is trying to do and what rule has been made in class.
D.A new learning style that the teacher enjoys using in history class.
小題2:According to the writer, the use of technology in the classroom may _____.
A.improve teaching and offer more help
B.a(chǎn)llow students to get on well with each other
C.help students concentrate on what they learn
D.keep students from making deep conversations
小題3:What can we infer from the passage?
A.The teacher will carry on the success in the future.
B.The teacher will have to cancel the rule in class.
C.Some students will be punished according to the rule.
D.More and more students will be absent in history class.

Everyone has got two personalities — the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control yourself, but when you're asleep, your sleeping positionshows the real you. In a normal night, of course, you often change your sleeping positions(姿勢). The important position that best shows your secret personality is the one that you go to sleep.
If you go to sleep on your back, you're a very open person. You normally trust(信任) people and you are easily influenced by new ideas. You don't like to make people unhappy, so you never express your real feelings. You're quite shy and you aren't very confident.
If you sleep on your stomach, you are a person who likes to keep secrets. You worry a lot and you're always easily becoming sad. You never want to change your ideas, but you are satisfied with your life the way it is. You usually live for today not for tomorrow.
If you sleep on curled up (蜷縮), you are probably a very nervous person. You have a low opinion of yourself and often protect yourself from being hurt, so you are very defensive. You're shy and you don't usually like meeting people. You like to be on your own.
If you sleep on your side, you have usually got a well-balanced personality. You know your strength and weakness. You're usually careful. You have a confident personality. You sometimes feel worried, but you don't often get unhappy. You always say what you think, even if it makes people angry.
