Suddenly another thought went through Kate’s mind like an electric shock. An express train was due to go past about thirty minutes later. If it were not stopped, that long train, full of passengers, would fall into the stream. “Someone must go to the station and warn the station-master，” Kate thought. But who was to go? She would have to go herself. There was no one else.

In wind and rain she started on her difficult way. Soon she was at the bridge that crossed the Des Moines River, a bridge also built of wood, just like the bridge across Honey Creek. The storm had not washed this away, but there was no footpath across it. She would have to cross it by stepping from sleeper (枕木)to sleeper. With great care she began the dangerous crossing, sometimes on her hands and knees, hardly daring to look down between the sleepers into the wild flood waters below. If she should slip, she would fall between the sleepers, into the rapidly flowing stream.

At last -- she never knew how long it had taken her- - she felt solid ground under her feet. But there was no time to rest. She still had to run more than half a mile and had only a few minutes left. Unless she reached the station before the express did, many, many lives would be lost.

She did reach the station just as the train came into sight. Fortunately the station-master was standing outside. “The bridge is down! Stop the train! Oh, please stop it!” Kate shouted breathlessly.

The station-master went pale. He rushed into the station building and came back with a signal light. He waved the red light as the train came into the station. It was not a second too early.

1.What did Kate decide to do?

A. Stop the express train. B. Check the signal light.

C. Meet the passengers. D. Visit the station-master

2.Which of the following words best describes Kate’s journey

A. Fruitless. B. Boring.

C. Well-planned. D. Risky.

3.Why did the station-master turn pale?

A. He suddenly fell ill. B. He realized the danger.

C. He discovered his mistake. D. He became over-excited.

Many teens in high school want to try out for sports. A lot of them try out because they think it will make them popular or get them more dates. While this may seem like a silly reason, there are lots of other benefits to sports that your children may fail to notice.

With TV, movies, computers and video games becoming more and more popular, it has become so much easier for teens to be by themselves rather than going out with friends. Kids used to go hang out at the mall or drive around town; now they just sit at home. Getting your teens into a sport gives them a chance to go out and spend time with other people socially. While they may not find a new best friend, they will learn how to communicate with one another and work as a team and they’ll find something useful later in life.

More and more kids are becoming overweight. Joining a team sport will help teens get out and get some exercise without feeling pressured to lose weight or get in shape. What’s more, if your teens see that their physical condition is causing them to under-perform, they may be encouraged to do other activities to get healthy. By the time your children reach their teenager year, part of good parenting will be providing them with direction and encouragement and continuing to help them develop a healthy style of living.

These days, it’s becoming harder to show your teenagers that you love and support them. A great way to do this is by showing up to their game, helping them practice, and helping with team fundraisers. These are also great ways to spend time with your kids and talk to them.

You may think “but my teen isn’t good enough to make their school team”. There are plenty of other places besides school to play team sports. You can always check out “for-fun” teams. You could look into more unknown sports that you may not have thought of, did you know that bowling is a NCAA team sports If you do a little research, you’re sure to find something your teen will enjoy.

Team sports are a great way for teens to get out of the house, get moving, make friends, and even get a scholarship to college. So why not talk to them about getting into sports today

1.After joining a sport, children may___________.

A. lose weight without any pressure.

B. find little pressure in learning.

C. be forced to do some exercise.

D. be provided with good parenting.

2.What does the under lined word “this” refer to?

A. To help teens develop a healthy lifestyle.

B. To show love to your teens.

C. To enable teens to know more about new places.

D. To motivate teens to get healthy.

Earlier this year, the social media website Facebook announced that it would work with several news organizations — including The New York Times, The Guardian, and the BBC — to place news stories directly into users’ personal Facebook webpage. Stories published using Facebook Instant will load more quickly and keep the style of the original publisher, who will keep all the advertising income the stories earn — at least for now. The deal shows how important social media has become to news organizations, and is a clear sign of how the world of news is changing — and has been for a while.

When Google News began in 2002, many saw it as the death of the newspaper. It had no human editor. Instead Google used, and still uses, a secret computer program that selects and displays news stories according to the reader’s personal interests. More recently, Associated Press and Yahoo! have been publishing computer-written articles. Both use special software to automatically produce stories about company financial results and sports reports — areas where the quality of writing is felt to be of secondary importance to the accuracy of the data.

Should we be worried about such developments? I think we should. One concern is that facebook, Google and other social media websites see journalism as a sideline, a way of putting people in front of advertisements. It isn’t their primary function — so if it stops making them lots of money, they're likely to stop doing it.

There’s also a concern that computer-written articles are not actually journalism at all, because what a human news team produces is actually quite complex. A well-written news story puts information in context, offers a voice to each side of an argument and brings the public new knowledge.

Though economics and speed of delivery mean readers will probably choose a computer-written story over a carefully shaped article — at least for daily news — I don't think the computers will be writing any in-depth articles for a while yet.

1.What is the main purpose of the article?

A. To report on a new computer service offered by Facebook..

B. To advise readers against reading computer-written news.

C. To express concern about recent trends in online news.

D. To describe the process of online news reporting.

2.Computer-written news reports have so far focused on sports and finance because ________.

A. these are the most popular topics for online readers

B. there are fewer journalists specializing in these areas

C. information on these topics is more easily available

D. writing style is less important than accuracy in these areas

3.What does the underlined word “It” in Paragraph 3 refer to?

A. Journalism. B. Advertising.

C. Facebook. D. Business.

4.In Paragraph 4, which of the following is mentioned as a characteristic of a well-written news article?

A. The information presented is up-to-date.

B. The author's opinion is clear.

C. Different views on the topic are presented.

D. The language used is vivid.

Grandma Pugh sized up the baby like a pig at the farmers’ market. There was a pause and then she pronounced. “He’s got nice long legs.” She clapped her hands once in approval. But then she frowned and leaned forward. Everyone waited anxiously. The baby had opened his eyes and was staring up. “But those cross eyes won’t do,” she declared firmly, shaking her head in disappointment.

That had been Freddie Pilcher’s first meeting with Grandma Pugh. Since then, ten years had passed. Much to his grandmother’s satisfaction, she’d been proven right about the boy’s legs. He was a regular beanpole. Grandma Pugh had also been correct about his eyes. Freddie had been wearing glasses to correct his vision since he was two years old. His current pair was thick, and cheap-looking, but at least he could see.

Freddie not only had poor eyesight, but he was also clumsy. He wasn’t good at schoolwork either. But there was one thing that the boy was good at and it was all on account of the length of his legs. He could jump.

Freddie was the best jumper in school. Not only could he leap the furthest but also the highest. At breaktimes, he entertained the little ones by leaping over the school wall into Mrs Hobson’s garden and then rapidly jumping back. She had been up to see the head teacher several times because somebody had been crushing her vegetables.

It was badgers (獾), Freddie suggested, when quizzed by Miss Harpy — definitely badgers; no doubt about it. His dad had terrible problems with badgers. Only last week he had lost two rows of carrots. Freddie had woken one night and heard them tearing through the garden, a whole herd of them. They rooted up the lawn and dug up the vegetables. Terrible things, badgers. All the other children nodded their heads wisely. There was a moment’s pause in Class Three as everyone thought about the dreadful damage that badgers could do.

1.What do we know about Grandma Pugh?

A. She was present at the birth of baby Freddie.

B. She was unwilling to listen to the ideas of others.

C. She was a figure of great importance in the family.

D. She valued physical appearance over all other things.

2.Why did Freddie jump over the school wall?

A. To annoy his teacher.

B. To escape from school.

C. To amuse his schoolmates.

D. To damage Mrs Hobson’s vegetables.

3.Which of the following best describes Freddie’s physical appearance?

A. B.

C. D.

4.Why does Freddie talk about badgers in the final paragraph?

A. To explain the cause of the damage.

B. To warn the class about their danger.

C. To describe what happened to his father’s garden.

D. To make up an excuse for the cause of the damage.
