But the mosquito may decide that she loves you. She? Yes, she. It’s true that male mosquito doesn’t bite(咬) and only the female mosquito bites because she needs blood to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from the others!If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly and quietly that you may not feel anything different. After she bites, you will have an itch(痒) on your body because she puts something from her mouth together with your blood By the time the itching begins, and she has flown away.

5、Many people believe that animals have feelings, but did you know that plants may have feelings, too Some people talk to their plants and that may not be such a bad idea at all. The research of at least one scientist gives strong evidence (证据)hat plants do have feelings of a sort and are able to react to things in ways that seem to reflect these feelings. The scientist attached(系上;贴上) a machine similar to a lie detector to a number of plants to record their reactions(反应 ) to being stimulated (刺激) in different ways. This po1ygraph (波动记录器) kept track of each plant＇s responses. A plant which was being watered demonstrated(证明,演示) a reaction similar to that of a person who is relaxing. Six student assistants aided the scientist with the plant research. One of the six was instructed to be nasty to the plants. This same student was then ordered to destroy one of two plants that were growing side by side. As the nasty student approached the plant, the plant reacted violently before being destroyed. All of the students then marched by the remaining plant. It reacted only when the destructive(破坏性的) student passed by. In still another experiment, plants were monitored(监测 )while live shrimp in another room were tossed(投) into boiling water. The plants did show measurable (可测量的) reactions when the shrimp were boi1e D Do plants really have feelings Try talking nicely to your plants and see if that makes a difference. This selection describes_____ .

5、China could save 10 million tons of grain a year if more attention was paid to the control of pests(害虫) , an agricultural scientist said. He also warned that plant diseases and pests are on the increase. Many kinds of pests, such as Asian locusts, which had been controlled for years, are spreading again. He said China loses about 15 million tons of grain a year as a result of damage done by plant diseases and pests. If crops were better protected, at least half of the lost grain could be save D He called for setting up a national office in charge of biological control using pests＇ natural enemies to kill them. Biological control is now used on slightly more than 10 percent of farmland of the country. Which of the following could be used as the title for the passage
