As temperatures go up, bison（北美野牛）get smaller. Joseph Craine, research assistant professor in the Division of Biology at Kansas State University, examined how climate change during the next 50 years will affect grazing（放牧）animals such as bison and cattle in the Great Plains.

“Bison are one of our most important conservation animals and hold a unique role in grasslands in North America,” Craine said. “In addition to their cultural and ecological significance, they’re economically important. There are about half a million bison in the world.” Craine analyzed a data set of 290,000 weights, ages and sexes collected from 22 bison herds（兽群）throughout the U. S. The organizations kept annual records of each animal in the herd and matched the data with the climates of the sites.

Based on differences in sizes of bison across herds, Craine found that during the next 50 years, future generations of bison will be smaller in size and weigh less. Climate is likely to reduce the nutritional quality of grasses, causing the animals to grow more slowly.

“We know that temperatures are going to go up,” Craine said. “We also know that warmer grasslands have grasses with less protein（蛋白质）, and we now know that warmer grasslands have smaller grazers. It all lines up to suggest that climate change will cause grasses to have less protein and cause grazers to gain less weight in the future.”

Craine said the results of climate change in coming decades can already be seen by comparing bison in cooler, wetter places with those in warmer, drier places. For example, the average 7-year-old male bison in South Dakota weighed 1, 900 pounds, while an average 7- year-old male bison in Oklahoma — a warmer place — weighed 1, 300 pounds.

“The difference in temperature between those two states is around 20 degrees Fahrenheit, which is about three times the projected increase in temperatures over the next 75 years,” Craine said. “It is a clear indicator that long-term warming will affect bison and is something that will happen across the U.S. over the next 50-75 years.”

Taking exams in a large group setting can be stressful for students and for the staff members who are watching over them.

When classrooms are crowded and desks are close together, cheating might be tempting.

One university in Thailand came up with an anti-cheating hat that makes it almost impossible for students to see other students’ papers. A photo of the students wearing the anti-cheating hats made its way to the Internet, and the university was criticized for making students wear those ridiculous looking homemade hats. The hats were made by stapling pieces of paper onto a headband, one to each side of the head.

After being criticized, senior academic staff at Kasetsart University in Bangkok, Thailand, released a statement saying that the hats idea came from students. They said that in a bid to prevent cheating they asked the students for ideas on how to prevent cheating in the upcoming exam, which was being taken by almost one hundred students. Students came up with different ideas, then the paper hat idea was selected by them as the most suitable.

The university claimed that no one was forced to use the hat, but they all chose to do so. “When wearing the hat during the exam, students felt more relaxed, ”Nattadon Rungruangkitkrai, a lecturer at the university said. “It was not meant to indicate that Kasetsart students often cheat on exams. I apologize if the photo makes other people look at my students in a negative way, ”Rungruangkitkrai added.

My house is made out of wood, glass and stone. It is also made out of software.

If you come to visit, you'll probably be surprised when you come in. Someone will give you an electronic PIN （个人身份号码）to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.

Of course, you are also able to tell the house if you want something. There is a home control console (控制台), a small machine that turns things on and off around you.

The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.

I believe that ten years from now, most new homes will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, "How will I live without them?"

1.What does the passage mainly discuss?

A. How to develop a new system.

B. The function of the PIN.

C. A home for the future.

D. Easy life in the future.

2.What's the purpose when the writer wrote the fourth paragraph?

A. To let readers know why his ideas are new.

B. To let readers know how special his house is.

C. To explain the importance of the PIN and the console.

D. To explain more easily what the functions of the PIN and the console are.

3.The writer's new house is different from ordinary ones mainly because _____.

A. it has been controlled by computers

B. you can make a telephone call anywhere

C. it has your favorite music following you

D. the writer is able to change his new idea into practice

4.What is the writer most likely to be according to the passage?

A. An IT expert. B. A famous doctor.

C. An idealist D. An experienced teacher.

She has already tried her best. Please don't be too _____ about her job.

Expressions about water are almost as common as water itself. But many of the expressions using water have unpleasant meanings.

The expression “to be in hot water” is one of them. It is a very old expression. “Hot water” was used 500 years ago to mean being in trouble. One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle．

That no longer happens. But we still get in “hot water”. When we are in “hot water”, we are in trouble. It can be any kind of trouble---serious or not so serious. A person who breaks a law can be in hot water with the police. A young boy can be in hot water with his mother if he walks in the house with dirty shoes．

Being in “deep water” is almost the same as being in hot water. When you are in deep water, you are in a difficult position. Imagine a person who cannot swim being thrown in water over his head. You are in deep water when you are facing a problem that you do not have the ability to solve. You can be in deep water, for example, if you invest in stocks without knowing anything about the stock market.

“To keep your head above water” is a colorful expression that means staying out of debt. A company seeks to keep its head above water during economic hard times. A man who loses his job tries to keep his head above water until he finds a new job．

“Water over the dam” is another expression about a past event. It is something that is finished. It cannot be changed. The expression comes from the idea that water that has flowed over a dam cannot be brought back again．

Another common expression, “to hold water”, is about the strength or weakness of an idea or opinion that you may be arguing about. It probably comes from a way of testing the condition of a container. If it can hold water, it is strong and has no holes in it. If your argument can hold water, it is strong and does not have any holes. If it does not hold water, then it is weak and not worth debating.

“Throwing cold water” also is an expression that deals with ideas or proposals. It means that one doesn’t like an idea. For example, you want to buy a new car because the old one has some problems. But your wife throws cold water on the idea because she says a new car costs too much.

In a modern society full of fierce competition , a person does is not always the same as he says.

A. what; what B. what ;that

C .that; that D. that ; what

Let’s say a person gets up at 7:00 in the morning and goes to bed at 11:00 at night. He comes home from work about 6:30, and by the time he has finished with dinner it is after 8:00. He steps outside in the summer to relax — but it’s already getting dark! Not much time to enjoy the summer day.

Now suppose you set the clock ahead one hour. This person still does everything at the same time — but this time, when he steps out at 8:00 there’s still plenty of light to enjoy. An hour of daylight has been “saved” for him!

Daylight saving time doesn’t, of course, add any hours to a day. This is impossible. All it does is to increase the number of useful hours of daylight during the seasons when the sun rises early.

Daylight saving is most popular in cities. It allows the closing of offices, shops, and factories at the end of the working day while the sun is still high. Farmers, who do their work by sun time, usually do not observe daylight saving time. They cannot work in the field before the morning dew(露水) has dried or after it appears in the evening.

Did you know who first thought of daylight saving time? It was Benjamin Franklin! When he was living in France in the 18th century, he suggested the idea to the people in Paris. But it was not adopted then.

Daylight saving laws were first passed during World WarⅠ, when materials for making electricity was hard to find, and when it was necessary to save on artificial light. With daylight saving, the bedtime of many people comes soon after it gets dark, while without it, if people stay up until the same hour they may have to use artificial light.

Germany was the first country to adopt daylight saving time in 1915. Then England used it in 1916, and the United States adopted it in 1918.

1.What does the underlined word “artificial” mean?

A. natural B. man-made

C. bright D. sun

2.What’s the purpose of adopting daylight saving time?

A. To have more artificial light.

B. To have one more hour to work.

C. To make better use of daylight in certain seasons.

D. To have one more hour to rest.

3.Which of the following is true according to the passage?

A. Once the idea of daylight saving time is proposed, it was adopted.

B. The idea of daylight saving time went through a long process of being adopted.

C. It was a French scientist that put forward the idea of daylight saving time.

D. The idea of daylight saving time didn’t make any difference at all.

4.What can be inferred from the passage?

A. Winter is a good season for daylight saving time.

B. Daylight saving time is especially good for wars.

C. Daylight saving time is good for anyone in any places.

D. Not all seasons are good for daylight saving time.
