【题目】

Khan Academy is a website providing a free education for any person. The website includes more than 4,000 short teaching videos about many different subjects. Every month, over 7 million people go to the Khan Academy website to watch its videos.

Khan Academy began with one man named Salman Khan. As a young man, Khan got a degree from Harvard Business School and began to work in business.

In 2006, Khan used the Internet to help his young cousins, who lived far away, with their mathematics schoolwork. He drew numbers and pictures on the website to teach them. After a time, he put his videos onto the website YouTube, where his cousins could watch them any time they wanted. But Khan noticed that other people were also watching his videos on YouTube.

By 2009, the number of people watching his videos on YouTube was getting very large. Khan decided to make the videos his job instead. So he officially began Khan Academy, providing videos on mathematics and other school subjects.

People did not have to pay to watch the videos. But they could give Khan money if they wanted to support (支持) his work. Some people did give Khan small amounts of money, but he was still having a hard time. Later, a woman told Khan that Bill Gates uses Khan Academy for his kids. After that, the Bill and Melinda Gates Foundation began giving money to Khan Academy. In 2010 Google gave the website money too, wanting Khan to translate his videos into the world’s most common languages. Today, people can see Khan’s videos in many different languages.

Some people think that Khan Academy will be the way more and more people learn in the future. Teachers can use it in their classrooms. Khan believes that Khan Academy will never, and should never, replace a school. But he believes teachers and students can use it to make schools better.

练习册系列答案

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question “How can I use a treadmill outdoors?” He finally came up with a new design, adding an electric motor, and the Lopifit was born. It’s similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery（电池）and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast（惯性滑行）, all you have to do is stay still and admire the view. To stop, you have two hand breaks.

The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you’re going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you “walk” really fast without much effort, or walking at cycling speed, if you will.

【1】Lopifit is an electric bicycle which ________.

A. can be powered by the drive chain

B. can work without an electric motor

C. works when you walk on the treadmill

D. stops when you slide the treadmill forward

【2】What is Paragraph 3 mainly about?

A. The design of a Lopifit. B. The function of a Lopifit.

C. The structure of a Lopifit. D. The operation of a Lopifit.

【3】What is probably the author’s attitude towards Lopifit?

A. Confident. B. Concerned.

C. Curious. D. Doubtful.

The new term is coming! It's time for school. Last term, I make little effort on my English, but my grades were not satisfying.

Dear Jack,

I’m sorry to hear that you feel lonely in the new school, because you find hard to make friends. Now, I’d like to offer you any advice.

Firstly, it’s normal for you to feel lonely because you were living in a new environment. Secondly, you should greet your classmates when met them on campus. Thirdly, it will be a good idea if you take an actively part in class activities, what can help them learn more about you. I believe you will be able to make new friends soon unless you’re friendly to the others.

I hope the suggestion above will be helpful to you and everything will be fine with you for the future.

Yours,

Li Hua

Last summer, to my delight, I got a chance to go to the United Kingdom. I was eager to see how England was like. Although my parents objected to my decision at first, but finally they were persuaded. It was the first time that I have travelled abroad alone. Felt excited, I boarded the plane. Suddenly, however, I found my luggages gone and felt helplessly. It was on that moment that the airhostess came to my assistance. After helping me find it back, she suggested that I attached a label to my suitcase on my next journey. I was thankful to the kind lady for his help! What unforgettable trip!

Dear classmates,

It is a pleasure for I to have a chance to make a short speech today. Recently I had found that some of our classmates study late into the night and do not spare some time to take a rest during the day either. They often cannot help fall asleep in class. And some classmates seldom have breakfast, that is also a bad habit and will surely do harm to our health.

In my opinion, it is extreme important for us to have enough sleep and a proper diet. We must learn to make a use of our time, and only in this way can we keep fit or study well. I wonder if you agree me.

Mistakes are something did, said or believed, as a result of wrong thinking or understanding, lack of knowledges or skills. No one is perfect, but no one makes no mistake. Because many people are afraid of making mistakes, we don’t believe, say or do much. They behaved like this just because they want to make no mistake. As I said, it’s impossible. Being afraid of making mistakes is mistake itself. Only through mistakes can there be discover or progress. Making mistakes for seeking truth is much more better than doing nothing. Mistakes are the best teachers which guide us through difficulties. Don’t let mistakes scare you. Let’s learn on mistakes.
