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.

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(装置) 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(主题) 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(打断) 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.
小题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. |
A.improve teaching and offer more help |
B.allow students to get on well with each other |
C.help students concentrate on what they learn |
D.keep students from making deep conversations |
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. |
We use the Internet for many things: business, shopping, writing letters, talking to people, finding information, and so on. In recent years, a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases (短语) into a few letters called acronyms(首字母缩略词). Acronyms are often used in chat rooms.
Some of them are:
BTW(by the way) BRB (be right back)
LOL (laughing out loud) IMO (in my opinion)
People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:
info (information) puter (computer) pic (picture) sec (second)
We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keyboards to draw “feeling”, such as:
: ) (happy) :-( (sad) ; : P (joking) : O (surprised)
These days, many forums have picture feelings. For example:
happy sad angry cool
There are even whole new words, like ‘newbie’ (someone who is new on a chat board or forum). When you write something bad about someone else, it’s called ‘flaming’ the person.
It takes time to get used to e-talk. Also, different groups in the Net have their own special ways of communicating. Newbies sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
小题1: Why do people type acronyms?
A.To show their feelings. |
B.To make jokes. |
C.Because people can type them quickly. |
D.In this way, newbies won’t understand them. |
A.The person is happy about getting a new computer. |
B.The person has to go away from their computer. |
C.The person is angry at somebody. |
D.The person is sad that his computer is having problems. |
A. | B. | C.LOL | D.BRB |
A.keep changing |
B.stay the same |
C.be used by people on the telephone |
D.be easy for newbies to understand |
A. doing shopping B. writing diaries
C. eating foods C. playing games
Almost all of us have unpleasant habits. We all want to get rid of(摆脱) them, but we don’t know proper ways. Here’s some advice.
●Write down all the reasons why you want to stop some behavior. Look at the reasons very often.
●It’s clever to do something else when you want to stop your bad habits. If you get angry easily, for example, you can go out for a walk.
●Decide what you’ll do to reward(奖励) yourself if you really get rid of your bad habits.
●If you get too heavy, keep junk food out of your house.
●Bad habits develop over years, so you can’t get rid of them very soon. So you should be patient.
●Don’t be afraid to ask others for support. You can talk to your friends, family or other people. When you talk to them, they might be able to provide some advice that you can’t get from yourself.

What will life be like in 3000? Different people have different answers. Here is my answer.
I think life will be very different in 3000. Every family will have a robot. The robot can do everything for people. So people won’t have to do heavy and dull work. And they will have more free time to enjoy the things they like.
People will wear special clothes in 3000. They don’t have to wash the clothes because the clothes won’t get dirty. There will be more kinds of food for people to enjoy. And they are all healthy food.
People will use energy(能量) from the sun and the wind. So there won’t be any pollution (污染)problems.
People will use a special car to travel. It can run on the road and fly in the air. It will be very easy for people to travel to the moon and other planets(星球). Some people will live in other planets.
It will be a happy world in 3000.
小题1:Most families will have a robot.
小题2:People won’t eat food in 3000.
小题3:There will no pollution problems in 3000.
小题4:It will be very difficult for people to travel to the moon.
小题5:People will still only live on the earth.
We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we tell it to others soon. But can you imagine that a tree can talk and share news too ? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
Willow (柳树) trees are the best-known of these trees. When insects begin nibbling (叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical (化学物质) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
小题1:Willow trees send messages with_____________.
A.words | B.movements | C.smells | D.sounds |
A.树干 | B.嘴唇 | C.枝条 | D.手势 |
A.speak just as people do | B.tell stories to others |
C.communicate with each other | D.kill insects in the woods |
a. The willow tree gives out a smell.
b. The willow trees make a chemical in their leaves.
c. Insects fly away because of the chemical.
d. Insects begin nibbling a willow tree.
A. d---a---b---c | B. d---b---a---c |
C. a---b---c---d | D. d---c---b---a |
