When it rains a lot, it will leave a lot of water in ponds and trees. These places are good for mosquitoes. Mosquitoes lay their eggs in the water. Warm weather will help the mosquito eggs to develop and then the number is increasing. Birds eat the mosquitoes and get sick. People can get the disease if they are bitten(叮咬) by mosquitoes with West Nile Virus.
The government is trying its best go stop the spread of West Nile Virus. People are asked to wear long sleeves(长袖)and pants, close their windows and shut the doors.

How do you like your school? Have you ever written to your headmaster to express your idea? Here are some letters written by students from different schools.
Luke, 14, from Jiangsu
I will give some suggestions about our school uniform. In our school, we students have to wear uniform every day. But the yellow and green sports kit（服装）looks really dark and old. It can’t stand for young and lively spirit. We can add some red or orange colors and make a new type of uniform. I hope our headmaster will think about it.
Danny, 14, from Zhejiang
I have two suggestions for my headmaster. First of all, I think we should have more hobby classes in science , such as plane model making class and computer programming class. It is really boring to study basic subjects all the time. And second, I hope we can have more PE lessons or more time for physical exercise. Lots of students now don’t have a strong enough body.
Sam, 15, from Shanxi
I’d like to say thank you to my headmaster. About one week ago, I got a bad cold after playing basketball. Our headmaster came to me after he knew about it. He took care of me until my parents came. I really want to thank him for that.
Helen, 14, from Shandong
In the letter I wrote, I want to talk about the possibility of personal（个性化的）classes. Now many middle schools are trying the “personal class” system. Students don’t have regular classes. They can choose lessons they want to take. I think it is more effective. And it is also good for exercise. We don’t have to stay in one classroom all the time.Luke gives some suggestions about ______ in his letter.
| A．hobby classes | B．personal classes |
| C．school uniform | D．basketball playing |
The reasons why Danny gives two suggestions are that ______.
| A．students have too few classes every day and they love sports |
| B．studying basic subjects only is boring and students are too weak |
| C．hobby classes are interesting and students have no PE lessons at all |
| D．students want to cancel the basic subjects and they want to have more sports lessons |
All the students except __ write to the headmaster to complain about something.
| A．Luke | B．Danny | C．Sam | D．Helen |
The underlined sentence “I think it is more effective” means “______”
| A．Regular classes will be more vivid and lively. |
| B．Regular classes will help students learn better. |
| C．Personal classes will be more vivid and lively. |
| D．Personal classes will help students learn better. |
According to the passage, most students write to their headmasters about ______.

The famous scientist and thinker, Charles Darwin(查尔斯·达尔文), was born on February 12, 1809. His family lived not far from the River Severn, England.
Charles’ father was a well-known doctor and the son of a still greater doctor and scientist. Charles’ father hoped that his son would also become a doctor.
As a boy Charles liked to go for walks in the fields and forests.83. He watched nature and compared what he saw with everything he had read in science books. He also liked collecting very much. He collected many things: eggs, stones, and leaves. His father did not like this, as Charles was not studying very well at school.
At the age of sixteen, Darwin was sent to Edinburgh University in order to become a doctor. But he was interested in the history of nature.
Then he studied at Cambridge University until 1831.
Some time later, he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His professor advised him to go. He said the trip would be just for Darwin. So when the ship left England in December 1831, Darwin was on it. The research lasted almost five years. The Beagle studied the waters in the sea near South America. It also visited New Zealand, Australia and islands in the Pacific. Darwin saw many new plants and animals. He collected all kinds of plants, which he sent home from the places he visited.
When he returned home, Darwin was warmly greeted by his families and many friends.
In 1842, Darwin went to live in Kent, where he continued his studies of the changes in nature. 84.Darwin understood that plants and animals are not always the same, and that they really change.
By 1859, Darwin had finished his famous book The Origin of Species（物种起源）. It made a great hit in the world of science. ③He was opposed (反对) by the church and even by some scientists. But later, more and more scientists agreed with him.
Darwin continued his studies in science until he died in 1882.

North American black bears are shy animals. They are fearful by nature, and will usually run away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals.
In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases(疾病), remove a tooth and take it to the lab to find out its age. Fromthese studies, researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies they produce.
But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapesto keep the bears busy, researchers can touch them to check their hearts, look at theirteeth, and do other jobs.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives.
In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But theresearch methods and the kinds of information that researchers, are able to collect are quite different.In the first paragraph, we can learn that North American black bears are _______.
| A．shy and fearful animals | B．not found today |
| C．well known to scientists | D．not afraid of people |
The word "remove" in the second paragraph probably means _____ in Chinese.
| A．拔下 | B．移植 | C．清洗 | D．修补 |
Which of the following may NOT be included in the New Jersey studies on bears?
| A．The age. | B．The way of their communication. |

| B．study the bears while they are asleep |
| C．use grapes to make the bears full |
| D．learn a lot about the bears' everyday lives |
What do the two studies have in common?
| A．Research places. | B．The main purpose. |
