A
?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.
As far as the Internet being a part of our lives, — well,?that train has left the station. There is no going back to an Internet-free life. But can using the Internet too much be bad for our health? It might be, say researchers. A new study finds that heavy Internet use may be connected to high blood pressure in a young group: teenagers.
The study results show that teens who spend at least 14 hours a week only online may cause high blood pressure, which 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 other diseases.
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.
The lead researcher is Andrea Cassidy Bush row. 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 stop to have a rest regularly from their computers or smartphones and do some kind of physical activity. She also suggests that parents shouldn’t let their children use the Internet for more than two hours a day, five days a week.
1.What does the underlined part “that train has left the station.” mean in paragraph 2?
A.?the train has stopped at the wrong station B.?life without the Internet is nowhere to be found
C.?the train has changed its course D.?there is something wrong with the station
2.What is Para. 3 mainly about?
A.?The advantages of Internet use.? B.?The harm of high blood pressure.
C.?The disadvantages of Internet use.? D.?Ways to prevent high blood pressure.
3.Andrea CassidyBushrow would agree that ________.
A.?teenagers shouldn’t use the Internet B.?the Internet will ruin human life in the future
C.?regular breaks are necessary when using the Internet D.?smartphones are more harmful than computers
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.?Every coin has two sides - so does the Internet. D.?Too much Internet use may be bad for teenagers.
B
Apple is known for offering the best customer service in the consumer technology market, such as Lenovo, Google and Nokia, in customer satisfaction surveys every year .
A particular story tells of how an Apple store manager broke a rule to earn a new, 10-year-old customer for life.
Matt tells us this touching story:
My daughter has been saving her birthday money and allowance for almost 9 months so that she could afford an iPod touch with a camera in it.
As of this morning, she had saved the amount needed and headed to an Apple store in Utah with my wife. They arrived at 10:30 am, not realizing that the store would be closed from 11 am to 2 am that day. As they approach the store, two friendly Apple employees greeted them and said they were sorry, but they were closed.
My wife pointed to my daughter who had a mason jar full of cash in her arms and explained why they were there and also pointed out that it was not quite 11 am yet. They again said they were sorry, but could not let them in. My wife and daughter were sad and regretful, but understood and made their way to another store in the mall.
About three stores down, an Apple employee raced after them and explained that the manager was going to make an exception and let them in. Every one of the employees stopped what they were doing as my daughter approached the register.
As she took all of the cash out of the mason jar, one employee stepped forward and said, “I don’t mean to bother you, but I have to tell you that this made my day wonderful.”
After the transaction(交易), my daughter and wife were on their way out, the store manager raised his voice and said to all of the employees, “Everyone, please give a round of applause for saving her money and buying an iPod today.”
5.What can we learn from the first paragraph?
A.Apple doesn’t do well in the customer service. B.Consumers are more satisfied with Apple
C.Nokia did better than Apple in the past. D.Customer satisfaction surveys are made every two years.
6. According to the text, Matt’s daughter would like to have________.
A.a computer B.an iPhone C.an iPod D.an iPod touch
7. According the passage, what is “a mason jar” ?
A.a money box B.a pot for cooking C.a coffee cup D.a candy box
8.What is the text mainly about ?
A.A good example on how to bargain with an Apple employee.
B.How a girl and her mother tried to buy what they wanted.
C.A touching story about how Apple earned a new customer for life.
D.The reason why a girl wanted to buy an Apple product.
C
Surfing the Internet for fun will make you a better employee, according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author Brent Coker said, “Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,” Coker said on the university’s website. “Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself, leading to a higher total Internet attention for a day’s work, and as a result, increases productivity(生产效率),”he said.
According to the study of 300 workers, 70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos. “Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online,” said Coker. “That’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation (适度), or were on the Internet for less than 20 percent of their total time in the office. “Those who spend too much time surfing the Internet will have a lower productivity than those without,” he said.
9.What does the University of Melbourne study mainly show?
A.People who surf the Internet are good employees.
B.Not everyone surfs the Internet for fun during office hours.
C.Surfing the Internet for fun during office hours increases productivity.
D.The Internet is becoming more and more important in people’s life.
10.According to Paragraph 3, Brent Coker would most probably agree that______.
A.the longer a person’s mind rests ,the better attention he will have
B.surfing the Internet is the best way to increase productivity
C.workers should have a long break during office hours
D.Workers should let their minds rest now and then
11.Which of the following is NOT mentioned in the passage as one of the most popular surfing activities?
A.Watching videos. B.Reading online news.
C.Reading online novels D.Playing online games.
12.What can we infer form the last paragraph?
A.Spending too much time surfing the Internet reduces productivity.
B.Those who never surf the Internet have the lowest productivity.
C.Most people don’t surf the Internet in moderation during office hours.
D.People should spend as little time as possible surfing the Internet.
第二节
Is there a link between social media and depression? Do social media have a negative impact on your mental health? It’s complicated.
In a recent study, the investigators compared social media use and depression between teens.
13 Specifically, for every hour per day that one teen spent on social media more than her peers, she likely had a 0.64 point higher depression score.
A different study published in 2018 identified five distinct types of social media users. The finding was that "problematic social media use" was one of the main themes for people whose mental health was affected by social media. You can have alcohol in your life without it being a problem, or your alcohol use may become problematic. 14______
There's one important thing to remember about survey research just because two things happen together, it's not necessarily true that one causes the other. 15 For all we know, it could be that people who are already more depressed choose to spend more time on social media.
16 If you think that we shouldn't paint social media with one broad brush, you're on the right track. On the one hand, participants often described social media as a valuable way to cope with stress. On the other hand, cyberbullying via social media was also a common experience for participants. Some also said that constantly checking their own social media profile was stressful.
It’s certainly possible that experiences like cyberbullying, comparing yourself to idealized images, and constantly monitoring your profile, are bad for your mood. It's also true for many that social media offer community support and positive messages. Given the inconclusive research, it's safe to say that at least we shouldn't write off social media altogether. 17 Anyway, you cannot use it as a crutch for coping with other stressors and mental health problems.
A.It's the same with social media.
B.Social media can be a double-edged sword.
C.People get more opinionated about the potential problems of social media.
D.They found that those who used social media more had higher depression scores.
E.They reviewed all existing research and found that there were both benefits and drawbacks.
F.The key to benefiting from social media may lie in using it in moderation and staying socially connected.
G.For example, just because higher social media use co-occurs with higher levels of depression doesn't mean social media use causes depression.
