China launched its second space laboratory, the Tiangong II, on Sept 15, which space officials say will become the country’s largest scientific platform in space to date.

The space lab was lifted off atop a Long March 2F carrier rocket from the Jiuquan Satellite Launch Center in Gansu province at 10:04 pm. Around 20 minutes later, the mission was declared a success.

The Tiangong II did preparations in space for about one month and then the Shenzhou XI manned spacecraft rocketed two astronauts to the lab on October 17th. The pair will make it their home for 30 days before being returned to Earth.

The lab’s predecessor, Tiangong I, was launched in September 2011 and was used mainly to test technology involved in space docking.

By comparison, the Tiangong II will be used to conduct more than 40 scientific and technological experiments together with the Shenzhou XI. That’s many times more than those carried out by the Tiangong I and the three previous Shenzhou spacecraft, according to Wu Ping, deputy director of the China Manned Space Agency. China’s manned space program has entered a “new phase of application and development,” he said.

On a cold winter day in Denver, I waited in line to see my hero, Jack Canfield, the co-author of the best-selling Chicken Soup for the Soul series and the author of The Success Principles. What Jack had become was a version of what I wanted to be.

During his talk, Jack took out his wallet, pulled out a hundred-dollar bill, and said, “Who wants this?”

Hands shot up in the audience; people leaned forward to see whom Jack would choose. But I ran up the stairs to the stage and grabbed the bill from his hand. He turned to me and said, “Yes, that’s it! Instead of waiting around for opportunities, simply take the initiative and create what we want!”

After this week, I asked for his personal e-mail address and sent him e-mail sharing my views and dreams. He kindly e-mailed back simple encouragement such as “Keep thinking and playing bigger; it’s much more fun that way. Love, Jack.” Then I got occupied with other things in life and I stopped e-mail Jack.

A year later, my dream gradually faded. I had this idea if I got back in touch with Jack. I e-mailed him again and again but got no response. As I sat down at my computer to check my e-mail for the fifth time in 15 minutes, an inspiration came like lighting: What was I doing? Was I waiting for the prize of life? I knew I needed to do something about all this waiting. I was going to write a book, which I would call “Waiting for Jack”!

It all sounded good, but then reality hit. Some nights I cried and wanted to give up. I wrote and rewrote. Even though I could feel the fear, I did it anyway. Fortunately, three years later, Waiting for Jack turns out a best-seller on Amazon!

We all have a “Jack” for whom we wait—whether it’s a person, a place or a thing. Now I would like to ask you: what are you waiting for?

1.From the first paragraph we can learn that the author _________.

A. wanted Jack to autograph her book

B. wanted to be as successful as Jack

C. wanted to make friends with Jack

D. wanted to get help from Jack

2.It can be inferred from the passage that Jack Canfield is probably a person who ________.

A. enjoys playing a lot

B. likes showing off his wealth

C. seldom takes risks

D. welcomes challenges in life

3.How did the author lose contact with Jack?

A. She and Jack had an argument.

B. She had no time to contact Jack.

C. Jack was too proud to get along with.

D. She was too upset with her broken dream.

4.What might be the theme of the book Waiting for Jack?

A. The disappointment of waiting for her hero Jack.

B. The need to keep waiting for the prize of our life.

C. The importance of taking action to achieve a goal.

D. The harm of blindly worshipping others as heroes.

科目:高中英語 來源:2017屆廣西桂林市高三上第三次10月考英語試卷(解析版) 題型:閱讀理解

In today's world of smart phones and laptops, most people have at least one time-telling thing with them. Since these digital products are so common, is time running out for the 500-year-old watch? According to some consumers, the answer is yes. New Jersey teenager Charlie Wollman says a watch is “an extra piece of equipment with no necessary function.” Many young adults think so and use their smart phones to tell time. It is said that fewer young people wear watches today than ten years ago. As a result, some people say that the watch industry is at a crossroads.

However, watchmakers optimistically say that watches redeem(挽回) popularity when consumers reach their 20s and 30s. By then, they are willing to spend money on a quality watch that doesn’t just keep good time. Fifty years ago, watchmakers took pride in their products’ accuracy. But in recent years, the watch industry has changed itself into an accessory(配飾) business. And today, the image a watch conveys has become more important than the time it tells.

“Complications” — features that go beyond simple timekeeping — are an important part of a watch’s image. Today’s watches offer lots of features that meet almost any personality. These features include compasses, USB drivers, and even other functions that measure the effectiveness of golf swings!

Creativity also plays a key role in designing today’s watches. For example, Japanese watchmaker Tokyoflash makes watches that don’t even look like watches. The company’s popular Shinshoku model uses different color lights to tell time. It looks more like a fashionable bracelet(手鐲) than a watch.

Whether a watch conveys fashion sense, creative talent or a love of sports, consumers want their watches to stand out. Nowadays, everyone has the same kind of little things in their bags, so people want to make a statement with what’s on their wrists. Will this interest in wrist fashion last? Only time will tell!

1.What can we know from the first paragraph?

A. As most people see, watches are out of fashion.

B. Some people feel that watches have been of no use.

C. The watch industry will close down sooner or later.

D. There are so many choices of watches for teenagers today.

2.According to the passage, what image does a watch convey nowadays?

A. It simply tells time.

B. It appeals to many teenagers.

C. It has many complex functions.

D. It has an impact on creativity and imagination.

3.Japanese watchmaker Tokyoflash is mentioned in Paragraph 4 to _________.

A. show why Shinshoku watches are popular

B. advertise Shinshoku watches made by Tokyoflash

C. make a comparison between watches and bracelets

D. tell that today’s watches need more imagination

4.What may be the best title for the passage?

A. Watches Tell More Than Time

B. Japanese Watches Stand Out

C. Watch Industry Is in a Bad Situation

D. Watches Are Becoming Less Popular
