The weather can influence(影响)intelligence(智力). For example, in a 1983 report by scientists, IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year(July and August).
Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot weather. At about 18 °C, people become stronger.
Lower air pressure may make people forgetful. People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18 °C.
Are you feeling sad, tired, forgetful or unhappy today? It may be the weather’s problem.
小题1:What can influence people’s intelligence according to the first paragraph?

A．Feeling.

B．Diet.

C．Health

D．Weather.

小题2:Students get worse on exams because ___________.

A．they take exams in hot months	B．they take exams in cold months

小题3:At a temperature of about 18 °C. people may_________.

D．Weather has nothing to do with people’s feelings.

Scientist Without Laboratories
When you hear the word “scitentist”, what do you think of? Many people think scientist are people in clean white coats who work in labs. And some scientists do work in labs. But there are   26  scientist who work in woods and jungles. These scientists are called “animal behavior (行为) scientists”, and they study animals as they live in nature.
Why don’t these scientists catch animals and study them in zoos? The   27  is in the word “behavior”. Animals behavior scientists want to learn   28  animal behave in their wild homes. When animals live in cages (笼子) or in zoos, they do not act the same as they do when they are   29 . They may fight   30  each other, or they may not eat, or they may not raise (抚养) their babies as they usually would. To see real animal behavior, scitentists must go where the animals   31 .
So animal behavior scientists go into the jungles, the woods or the desert. There , their most important   32  are their eyes and ears. They watch and listen to the animals very   33 . They write down everything that happened in notebook.   34
they live near the animals, the scientists are careful not to frighten them. If the scientists are luncky, the animals will   35  no attention to them. Then the scientists can see how the animals really live.
The behavior scientists hope what they’ve learned about animal behavoir can provide clues (提供线索) to help people learn to live together more happily.

A fish that lives in America can live out. of water for months at a time, similar to how animals got used to land millions of years ago, a new study shows.
The Mangrove Rivulus, a kind of little fish, lives in small pools of water. When their living place dries up, they live. on the land, said Scott Taylor, a researcher in Florida.
The fish can grow as large as three inches. They group together and breathe air through their skin before they can find water again.
The new scientific discovery came during a trip.
"We were travelling for fun. and one day I kicked over a log (圆木) and the fish came out," Taylor told reporters by telephone. He said he would make his study on the fish known to the public in an American magazine early next year.
In lab tests, Taylor said he found the fish can live up to 66 days out of water without eating.
Some other fish can live out of water for a short period of time. The walking catfish found in Southeast Asia can stay on land for hours at a time, while lungfish(肺鱼) found in Australia, Africa and South America can live out of water, but only in a not active(活波的)way. But no other known fish can be out of water as long as the Mangrove Rivulus and keep active, according to Patricia Wright, a biologist at a Canadian University.
More studies of the fish may tell how animals changed over time.
"These animals live in conditions similar to those millions of years ago, when animals began to move from water onto land," Wright said.

A．lives on land in Africa

In many high schools，there are strict rules about using mobile phones. If your phone rings in class，for example，the teacher will be very angry.
Every mobile phone has a ringtone (铃声). It tells you that someone is calling you. Now，there is a ringtone called “mosquitotone (蚊子铃声)”. Using it，students can receive calls and text messages (短信) in class but the teacher will not realize what is happening. How?
Mosquitotone has a special sound. Only children and teenagers can hear it. As we get older，we are unable to hear some sounds with high frequencies (频率). As a result，a child or teenager can hear the mosquitotone ringtone, but it’s_inaudible_to someone 20 or older.
But sometimes，people over 20 can hear the ringtone. One British student’s phone uses mosquitotone. In class，the student’s phone rang. The 32yearold teacher looked at the student and became unhappy. “I heard that. You know the rule：no mobile phone in class.”
Not all the students are interested in mosquitotone. Jerry Jones，a high school student of 17，says，“Using mosquitotone too often is bad for our hearing. I may use it for pleasure，but not in class. It’s unfair to the teachers！”
What do parents think of mosquitotone？“I think it is perfect for places like movie theaters，” says Connie Neeson,44.“Think about it. Yon’re watching a film and someone’s mobile phone rings. Mosquitotone is good because many people don’t hear it. However，it also has a bad influence on their study if students use it in class.”
小题1:Mosquitotone works because ________.

A．it is very loud	B．it has no sound
C．it has a beautiful sound	D．it uses high frequencies

小题2:The under lined part “it’s_inaudible_to” means “________”．

A．it can’t be seen by	B．it can’t be heard by
C．it isn’t popular with	D．it isn’t healthy for

小题3:The 32yearold teacher felt unhappy because the student ________.

A．was late for class	B．didn’t do his homework
C．couldn’t answer her question	D．was using a mobile phone in class

小题4:Connie Neeson thinks that mosquitotone ________.
