Some other students listen to MP3 players when they are having a lesson that they are not interested in.
Are these new students really that r 12 “Yes.” says Delaney Kirk, a professor at Drake University. But she adds it’s not their fault. I 13 , the teachers should be blamed (责备). Mrs. Kirk first began thinking about student’s manners six years ago. “I had my first class in which students were sleeping or talking to each other. It seemed that learning well had n 14 to do with them.” she says. “At first, I got worried about this, but then I said to myself: You’re giving lessons, and you need to m 15 this kind of situation. These students need to know more about manners. It’s time to help them develop some good h 16 . They shouldn’t waste time when they are young. Sooner or later, they may feel sorry about the time they have wasted.”
Mrs. Kirk also gives some advice to help teachers during their classes. The following are her s 17 .
●On the first day of class, tell students how they will benefit (受益) by taking the class and the important of listening carefully in class.
●Do not allow them to bring cell phones or MP3 players to the class at all.

Reading for pleasure is the easiest way to become a better reader in English. It is also the most important way. Some students say they don’t want to read for 18 . They say they want to use their time to learn the rules of the language and new words. They say that pleasure reading is too easy.
Many 19 say pleasure reading is very important for learning English. Dr. Stephen Krashen, a famous expert on learning languages, says that pleasure reading helps you learn many important things about English. Students learn more grammar and more words when they read for pleasure. They also learn more about good writing. Dr. Krashen tells us that pleasure reading helps each student to learn something for himself. Pleasure reading makes it 20 for each student to learn what he or she needs.
Reading for pleasure is not the same as studying. When you read for pleasure, you 21 your own books, and you don’t have to remember everything. There are no tests on your pleasure reading books. Pleasure reading will help you:

Answer the questions. (根据短文内容，回答下列问题。）
Can plants eat people Probably not, but there are many plants that eat meat. Some of them are big. And they can eat small animals. One famous meat-eating plant is the Venus flytrap (捕蝇草).
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!
33．The Venus flytrap is a plant which eats flies, isn’t it
34．Where does the Venus flytrap grow
35．What does the meat-eating plant look like
36．What is inside the leaves of the plant

七、阅读理解
Have you ever heard of e-waste (电子垃圾), which can be produced every day How do you deal with your computers, MP4 players and mobile phones when they’re broken or you want a new one
Most people just throw them away. With the development of electronic industry (电子产业), e-waste pollution has become a serious problem. According to the United Nations, in 2014, people around the world produced 41.8 million tons (吨) of e-waste and only recycled 6.5 million tons. The US was the biggest waster, producing 7.1 million tons. China came second, with 6 million tons.
It’s important to pay attention to e-waste. It can either be valuable or harmful, depending on how we deal with it. E-waste is a valuable urban mine (城市矿藏). The value of the metals, like gold and silver in the waste around the world, is surprising. And the metals can be reused. But if people throw them away, the toxic chemicals (有毒化学物质) can get into the earth or air, affecting the environment and people’s health.
Apple, for example, now recycles people’s used products in China when they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce e-waste, we can buy longer lasting electronic products. If you have unwanted electronics, find a new home for them. You can also take computers and phones to see if companies offer recycling programs.

A．computers B．mobile phones C．plastic bags D．MP4 players
