文档简介
Unit 3 The Internet
一、阅读理解
1. The Internet plays a big part in human life. We use it for work and pleasure. We use it to learn a new language. We find advice on it. We use it to connect with family and friends. We use it to stay in touch with events we care about. The list goes on and on.
Well, that train has left the station. But can using the Internet too much be bad for our health It might be, researchers say. A new study finds that heavy Internet use may be connected to high blood pressure(血压) in an unlikely group: teenagers.
High blood pressure makes your heart and blood vessels(血管) work too hard. Over time, this extra pressure increases your risk of a heart attack. High blood pressure can also cause heart and kidney(肾脏) disease. It is also closely linked to a brain disease.
The Henry Ford Hospital in Detroit, Michigan did the study. 335 young people, from 14 to 17 years old, took part in it. 134 of the teens were described as "heavy Internet users". And researchers found that out of these 134 teens, 26 had high blood pressure. The researchers say the study is the first to connect heavy Web use with high blood pressure. Other research has connected heavy Internet use with anxiety, depression and obesity(肥胖).
The lead researcher is Andrea Cassidy-Bushrow. She said, "Using the Internet is part of our daily life, but it shouldn't ruin us." Ms Cassidy-Bushrow adds that it is important for teens to take regular breaks from their computers or smartphones and do some kind of physical activity. She also suggests that parents limit their children's use of the Internet to two hours a day, five days a week.
1. The expression "that train has left the station" in Para. 2 is used to show _______.
A. the Internet develops rapidly
B. no one can escape from the Internet
C. the Internet can provide whatever we want
D. there is no going back to an Internet-free life
2. What is Para. 3 mainly about
A. Causes of high blood pressure.
B. The harm of high blood pressure.
C. The disadvantages of Internet use.
D. Ways to prevent high blood pressure.
3. Andrea Cassidy-Bushrow would agree that _______.
A. teenagers shouldn't use the Internet
B. the Internet will ruin human life in the future
C. smartphones are more harmful than computers
D. regular breaks are necessary when using the Internet
4. What can be used as the best title of the passage
A. Heavy Internet users are mostly teenagers
B. How to prevent teenagers from the Internet
C. Too much Internet use may be bad for teenagers
D. Every coin has two sides—so does the Internet
二、七选五

15.答案：
The negative effects of using cellphones on students
As we all know, more and more students use cellphones in school nowadays. Though a cellphone is a useful tool, it could have lots of negative effects on students.
Firstly, using cellphones for a long time does harm to students' health, especially to their eyesight. Secondly, by making calls and sending messages, students seldom communicate with relatives and friends face to face. Thirdly, some students send messages or watch videos instead of listening to teachers in class. As a result, their school grades go down rapidly. Last but not least, students who play with cellphones often have less time to play sports.
Therefore, parents and teachers should limit children's using cellphones.
