1 . As young people spend more time on computers, iPad and other TV sets, researchers are asking how all that screen time affects children’s and teenagers’ ability to focus and learn — even drive cars.

An online survey offers a new question: how is technology affecting their happiness and emotional development? The answer, from girls ages 8 to 12 having the online habits, is that those who say they spend amounts of time using multimedia describe themselves in ways that suggest they are less happy and less socially comfortable than other teenagers who say they spend less time on screens.

Among the key questions that the researchers are not able to answer is whether the heavy use of media is the cause for the relative unhappiness or whether girls who are less happy to begin with are drawn to heavy use of media, in fact, coming to a virtual (虚拟的) world. But the researchers assume that heavy use of media is a main factor to the social challenges of girls.

The reason the researchers say is that on a basic level girls need to experience the full face-to-face communication, such as learning to read body language and facial expressions.

Lucy Gray, 45, who lives in Chicago, said her daughter, Julia, 13 has been a heavy consumer of media for several years -she watches movies on her laptop, and has an iPad, an iPhone and a Nintendo DS portable game machine. Ms. Gray said that Julia can have trouble getting on with other people especially adults in face-to-face interactions, but she is not ready to blame her daughter’s heavy use of technology.

In fact, she thinks that, on the whole, the technology has helped her daughter navigate (航行) the world socially. “She’d be missing out on an opportunity if she wasn’t connected,” she said.

At the same time, Ms. Gray said she worries that her daughter, who is using Facebook more, is playing out her social life online sometimes without the benefits of the full emotional range that comes from face-to-face interaction.

“It’s a double-edged sword,” Ms. Gray said to social media.

The combination of mobile phones and the Internet has brought us a lot of     1     (益处；好处), such as online shopping, information searching, keeping track of events, chatting...

So one phrase is born, “smart phone addict”. Wherever they are, this group of persons are buried in the phone, and completely cut off from the outside world.

Strict regulations must be made to protect children. First, children’s games     12     (被禁止) go online. Second, parents should be pressed to change their     13     (错误的；不正确的) attitudes towards children’s education. I sincerely hope a solid foundation can be laid for the future development of children.

8 . Wikipedia (维基百科) started in 2001 and has quickly gone from having just a few pages to having millions of pages with all kinds of information. It is even an ad-free website as it receives money from donations (捐赠).

Wikipedia is one of the most useful sites for students across the world. But because Wikipedia allows the public to freely edit (编辑) pages, should teachers allow their students to use the site to help them with their studies?

History teacher Luca Signore said, “I think it has good information and it is great for a starting point as you can quickly find information. I use it myself. However, it still gets edited by people who are not experts. You have no way of knowing whether something is completely true for certain.”

Students agree that Wikipedia may be the easiest site to get information from and it is especially helpful in history classes. Junior Alison Snyder believes, “You can use it for general background information, but as much as I’d like to, we shouldn’t be able to cite (引用) Wikipedia.”

Teachers should be able to allow students to use the site on a regular basis as the site is an amazing tool for students to quickly and easily get information for a class. However, it is clear that students shouldn’t be allowed to cite sources as some of the information might be a little bit incorrect.

Junior Maxine Moss agrees. “Yes, students should be able to use it on a regular basis because it is probably the easiest site to find information, but it is hard to tell if certain things are totally true.”

It is agreed that students should be allowed to use the website to get information as pages are, for the most part, fairly correct. However, citing items is a totally different story as the pages used on Wikipedia could have incorrect information and there are so many other sources out there with similar information from experts on certain subject matters.

1. What is good about Wikipedia according to Paragraph 1?

A．it can be freely edited.	B．It was created by teachers.
C．It has no advertisements.	D．It provides free information.

2. What do we know about Luca Signore?

A．He seldom uses Wikipedia.

B．He is against people editing Wikipedia.

C．He doesn’t allow his students to use Wikipedia.

D．He believes Wikipedia should be used in certain ways.

3. How does Maxine Moss agree with Alison Snyder?

A．Wikipedia is full of little mistakes.

B．Wikipedia is more trouble than help.

C．Wikipedia is helpful to some degree.

D．Wikipedia is not proper for students.

4. What does the author think of citing information on Wikipedia?

A．It is risky.	B．It is boring.
C．It is a wise choice.	D．It is OK for beginners.

9 . The current generation is not like any other generation I have seen in history. Due to the rise in technology, the world is evolving fast and changing the way most of us do things. Today’s young generation is so used to the technology which they learn very quickly. It could be considered as a benediction, but there are times when it is not appropriate.

In my generation, we met friends face to face to have real conversations rather than texting each other all the time. We walked everywhere, to the store or up the stairs instead of climbing into our car or on a motored skateboard each time we had to go two or three blocks away.

Most of the new generation expects things to be done for them. If something requires some extra effort or focus, they are easily discouraged. But if we want to reach success in this day and age, it is expected of us to work to achieve our dreams. The old generation knows that the world does not owe them squat. It understands that no one else than them can do it and that is their responsibility to make something of themselves.

Nowadays, there is no longer a sense of honor, because most people hide behind a computer screen. When you handle issues or hate for no reason over social media, it just proves that you are a weak person. I just put an ad in one of my groups for teaching Kung Fu, and one hater wrote “Kung Fu clown.” And this is for no reason as I have never seen or met the guy before.

The new generation relies too much on social media for their lives and doing things. It is okay to use it but not to abuse it. My final word is that each generation has its own advantages and downsides, but what matters is that each generation, old or new, has to give lessons which are valuable for future generations.

1. What does the underlined word “benediction” in Paragraph 1 mean?

A．Drawback.

A．By analyzing reasons.	B．By explaining concepts.
C．By criticizing young guys.	D．By comparing generations.

3. What does the author demonstrate by talking about his ad?

A．The rapid development of social media.	B．The tough situations for future generations.
C．New generation’s inappropriate behaviour.	D．Genuine strangers behind computer screens.

4. Which of the following is a suitable title for the text?

A．The balanced use of social media	B．Lessons for old generations
C．The growth of new technology	D．No reason for hating others

10 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Don’t brag(炫耀), but be proud of what you have done. These two pieces of advice     1     (be) tough to balance before Facebook existed. Even today’s share-it-all social media haven’t made     2     any easier. We are     3     (able) to draw a line between a humble bragging and a straight-up bragging. But we certainly know that oversharing doesn’t do your friendship any favors.

Social media like Facebook bring us     4     (convenient). Meanwhile, they can put us     5     danger of oversharing. Once upon a time, only your family and close friends would be there     6     (see) you eagerly open presents on Christmas morning. Now the photo     7     you take on your iPhone will likely become a touch-up Instagram in about 15 seconds. Maybe you just post it subconsciously. But your sharing behavior could     8     (easy) be considered annoying or even narcissistic(自恋的).

To post or not to post? Maybe we should all be asking     9     (we) the question before hitting the share button. As our personal fame grows alongside our social media presences, so     10     (do) the number of people we could potentially(潜在地) impress or bother.
