The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly touches one of the hairs, the leaf closes quickly. The fly cannot get out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly.
Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn"t have all these important things, especially nitrogen(氮). Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let"s hope that some of the bigger plants don"t get the same idea!
小题1:The Venus flytrap is a kind of _________.
A.plant | B.animal | C.food | D.meat |
A.挤压 | B.关上 | C.打开 | D.松开 |
A.Because plants are dangerous to animals. |
B.Because animals are dangerous to plants. |
C.Because plants want to get what they need from animal meat. |

Since several years ago, more and more people have used micro blogs in our country.Recent surveys (调查) shows that most students in middle schools have a micro blog and some even update (更新) their blogs over five times per day.
“We learn many fresh and interesting things on micro blogs and they have become popular topics in class,” said Kitty Jiang, 14.“If you do not know about them, you are out of loop.” It is also a great place for students to say something about themselves.“My parents always ask me to study hard, and encourage me before exams, but it really gives me pressure (压力),” said Alan Wang, 15.“I share these feelings on my micro blog.My friends always give me answers in the same situation.This makes me feel better.”
But parents worry that micro blogging could be a waste of time.Some unhealthy information may even bring danger to kids, they said.
Mr Shen, a professor (教授) asks parents not to worry too much as long as kids are not crazy about micro blogging.Maybe it can become a window for parents to understand their children.“If parents can read their children’s micro blogs, they’ll know what they think, they can know more about their children and help them solve their problems,” he said.He also gives some advice for kids.
-Don’t micro blog for more than one hour a day.
-Never micro blog in class.
-Try to talk face to face with people from time to time.
-Don’t believe all the information on a micro blog.
小题1:According to the passage, what do students log on to their micro blogs to do?
A.check the things | B.write articles |
C.listen to music | D.call their parents |
A.not excited | B.unhealthy | C.unlucky | D.not popular |

B.It will bring a lot of unhealthy information. |
C.It becomes a window to understand young kids. |
D.It will not solve problems for kids |
A.It’s good for kids to micro blog for more than one hour a day. |
B.Kids should believe all the messages on a micro blog because they are useful. |
C.Many young people have written something on micro blogs since two years ago. |
D.Kids should try to talk face to face with people, not just micro blogging. |
If you are slow in speaking, don’t worry.One of the helpful ways is reading, either aloud or to yourself.The important thing is to choose something interesting to read.It mustn’t be too difficult for you.When you are reading in this way, don’t stop to look up the words if you can guess their meanings, or they have nothing important to do with the sentence.You can look them up later.
