Ⅱ.阅读理解

A

 It started as a special day for Wesley Autrey，a 50­year­old construction worker in New York City.It was about 12：45 PM，and he was waiting on a subway platform (月台) to take his daughters home before he went to work.He suddenly noticed a man nearby have convulsions (抽搐) and fall down suddenly.Mr Autrey and two women went to help the stranger.The man，Cameron Hollopeter，managed to get to his feet，but then stumbled (绊倒) at the edge of the platform and fell onto the subway tracks.Mr  Autrey looked up and saw the lights of the subway train coming near through the tunnel.

Mr  Autrey jumped onto the track immediately.He  realized  that  he  didn’t  have  time  to  get  Mr  Hollopeter and himself back up on the platform before the train arrived，so he lay on top of the man and pressed down as hard as he could.Although the driver tried to stop the train before it reached them，He couldn’t.Five cars passed over them before the train finally stopped.The cars had passed only inches from his head.

New York loves a hero.Mr Autrey became an overnight  hero  and  was  named  the  “Subway Superman”．New York City Mayor Michael Bloomberg gave him the Bronze Medallion，the city’s highest honor.He was asked to appear on several TV talk shows.He was also rewarded with money and gifts，such as $10,000 from Donald Trump，a $5,000 gift card from the Gap clothing store，a new Jeep，and Beyonce concert tickets.

How did Autrey react (反应) to all this？He said，“I don’t feel like I did anything great；I just saw someone who needed help.I did what I felt was right”．

The idea behind Facebook is to make us feel connected all the time.But in my research，I’ve found that the truth is quite different.

Technology，it turns out，has made being alone seem like a problem that needs solving.When young people are alone，even for a minute or two，they feel the need to connect，to get on Facebook or some other social networks and chat.But in connecting，they often end up feeling more isolated.Why？Because by being in constant (不断的) connection，they lose the ability to feel satisfied with their own company (独处)．

Facebook can help us keep in touch with our  friends，but we too often use it instead of spending  face­to­face time with them.And since we feel the  need to keep up with them  online，we don’t have  moments of loneliness where we can collect our  thoughts and learn how to be comfortable being  alone.

—Sherry Turkle，Professor

Facebook connects more of us to more of our  friends and family in more places than we have ever  been connected before.Yes，Facebook is a huge time  sink—maybe the biggest ever.Many people post  useless stuff.And seeing too much of your friends’  lives can make you jealous (嫉妒的)，but it won’t  make you lonely.

Jane，a former student of mine，who is back in  New York after living abroad for ten years，told me  that Facebook helps her a lot.The first time she  moved back to New York from abroad，She felt  disconnected from her family and friends.Now，because of lots of photos and information updates (更新)，she knows what is happening with her friends all the time.

In fact，if you are lonely in real life，you will be lonely online as well.

—Sree Sreenivasan，Chief Digital Officer

语篇解读　本文是议论文。文章探讨了社交网络是否使人们变得越来越孤独。

5．The underlined word “isolated” in Paragraph 2    means________.

A．free B．selfish

C．careless D．lonely

解析：　词义猜测题。根据第二段的made being alone seem like a problem，When young people are alone可知，isolated此处指“孤独的”，故选D项。

答案：　D

6．According to Sherry Turkle，we should ________.

A．feel satisfied with our life

B．avoid using social networks

C．keep in touch with our friends

D．enjoy moments of loneliness

解析：　细节理解题。根据第三段的we don’t have moments of loneliness where we can collect our thoughts and learn how to be comfortable being alone可知，Sherry Turkle认为我们应该学会享受孤独。

答案：　D

7．What’s Jane’s attitude towards Facebook?

A．Hopeful. B．Doubtful.

 C．Thankful. D．Regretful.

解析：　推理判断题。根据倒数第二段Jane描述她从Facebook里了解朋友们的生活以及Facebook helps her a lot可知，Jane对Facebook充满感激之情。

答案：　C

8．The purpose of the text is to________.

 A．educate B．discuss

 C．persuade           D．introduce

解析：　写作目的题。从本文贯穿始终的alone和lonely以及两位人士对社交网络Facebook的不同观点可知，本文对社交网络是否使人们变得越来越孤独进行了探讨。

答案：　B

Ⅲ.七选五

The dangers faced by the ocean may seem terrible.In the face of  pollution，climate change and other serious problems，what you can do alone   may seem little.__1__ Here are some ways to get started：

•Be water­wise.All waters on the earth are connected，so you can help   keep the ocean clean by using as little fertilizer (化肥) as possible when  growing plants in your yard.__2__Much energy is wasted in transporting foods  from far away.What’s more，remember that trash you throw away doesn’t   disappear.So don’t throw wastes into the ocean.

•Be fish­friendly.Scientists guess that up to 90% of large predatory  fish (those that eat other animals) have disappeared since humans began   heavy fishing.__3__  You should choose sustainable (可持续的) seafood in restaurants.When fishing on your own，make sure you follow all local catch limits.

•Cut carbon.We should try to reduce the amount of carbon dioxide given off as we go about our daily activities.__4__

• __5__A trip to the ocean is a great way to learn more about the ocean.But when you visit，make sure you aren’t causing harm.If you plan to take a cruise for your next vacation，do some research to find the most eco­friendly way.

A．Travel the ocean in a responsible way.

B．To protect fish，you need to watch what you eat.
