【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

It is a great truth that once we truly understand and accept it, life is no longer difficult. Most people do not fully see this truth. 1 It seems to them that their difficulties represent a special kind of suffering especially forced upon them or their families, their class, or even their nation.

2 Problems, depending on their nature, cause us sadness or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.

3

4 When we desire to encourage the growth of the human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. 5 As Benjamin Franklin said, Those things that hurt, instruct. It is for this reason that wise people learn not to fear but to welcome the pain of problems.

A. Problems are the serious test that tells success from failure.

B. Life is not a trap set for us by God so that he can condemn us for failing.

C. It is through the pain of meeting and working out problems that we learn.

D. Yet, it is in this whole process of solving problems that we understand the meaning of life.

E. Instead they complain about their problems and difficulties as if we understand the meaning of life.

F. We can participate in problem-solving collaboration(合作) groups.

G. What makes life difficult is that the process of facing and solving problems is a painful one.

【题目】B

My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t get any channels showing all-night movies or I would never have gotten to bed.

Then I started developing a problem with the set that involved static(静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it, I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles(肌肉) shaking my set.

When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

【1】 Why did the author say he was fooled into buying the TV set?

A. He got an older model than he had expected.

B. He couldn’t return it when it was broken.

C. He could have bought it at a lower price.

D. He failed to find any movie shows on it.

【2】Which of the following can best replace the phrase "signed off" in Paragraph 1?

A. ended all their programs B. provided fewer channels

C. changed to commercials D. showed all-night movies

【3】How did the author finally get his TV set working again?

A. By shaking and hitting it. B. By turning it on and off.

C. By switching channels. D. By having it repaired.

【4】How does the author sound when telling the story?

A. Curious. B. Anxious.

C. Cautious. D. Humorous.

Facebook Is a Big Waste

During the first decade of the 21st century, a popular and new word has come into our vocabulary—Facebook. This is the most popular social networking website on the Internet. 1 You can send messages to your friend’s electronic wall, put up a status saying something like "Going to the mall, I need to get a new pair of shoes" or "it’s finally the weekend!:)".

In spite of the benefit it does on common people, it is true that this social network is a big waster. There are about 350 million active users on this website and 67% of them are between the ages of 1325.More than 35 million users update their status every day. 2

The highest age group who use Facebook are teenagers. Most of them keep the website running whenever they are using the computer, if they aren’t in school or when they aren’t asleep. Facebook is just changing the new generation of youngsters unconsciously. The teenage life is one of the most important stages of life, 3 It is a distraction to their mind as well. Nowadays, when all their homework and research are on ICT(信息技术)they would easily switch to Facebook just to check if there was anything updated among their friends.

Facebook is also where people can see the gossip among their friends, virtual arguments, relationship status and updates, who is in whose "top friends", you can become fan of anything, join groups, post pictures and videos, play childish games, invite friends to parties or events and a lot more. Generally, all these would just disturb people into living life to the fullest. It’s not just teens who become addicted, even grown-ups do. An average person spends about 55 minutes on Facebook. 4 Technology might be taking over people’s life.

This shows people using Facebook on their phones as well as computers just can’t stand being away from the website. Facebook is like crack to some folk.

5 This would make them think how life is like without saying what’s on their mind to all their friends on the Internet. A break would also make them more active, like socializing in person. This would finally help them focus better in school or in work. Although about 80% of people who take a break would come back to Facebook within days.

A. And 2.5 billion photos are added each month.

B. Wasting it on Facebook is not encouraging in any way.

C. This statistic isn’t that bad but some people spend about 3-5 hours.

D. It is time people should take a break from Facebook once in a while.

E. As a result, the average Facebook users have 130 friends who they share links with.

F. Usually, when people hear the words "social networking", their brains automatically go to sites such as Twitter or Facebook.

G. The main idea of Facebook is that you can keep in touch with all your /span>friends around the world who have Facebook.
