Now, in the 21st century, there are lots of great inventions.1. However, while we are enjoying these, we should never forget those who devoted themselves to making people's life better in the 20th century.
2. Like many other famous inventors, they had failed many times. However, they never gave up —even though almost no one was interested in what they were doing. For many times, they risked their lives to test their airplane. Finally, after lots of calculations and improvements, they succeeded.
3. The invention led to a quantum leap in human history. From then on, better and safer airplanes have been invented and long flights have become increasingly convenient and comfortable. Their aroundtheworld trips have become a reality. Without the Wright brothers, we might still have to spend days, weeks or even months travelling to distant places today.
The Wright brothers have also inspired generations of people to make great achievements in their own fields. China, for example, had to depend on the Western countries for their large airplanes. Of course, our country didn't want to continue that way forever. With the same adventurous spirit as that of the Wright brothers, Chinese people kept trying and made great progress. Today, China has its own large airplanes.4.
Thanks to the Wright brothers, humans realized the dream of flying. Till today, their experiences still have a great influence on young people.5. I think they are among the greatest people of the 20th century.
A.That's an important step forward.
B.The result of their work shocked the world.
C.In 1903, the Wright brothers invented the airplane.
D.They inspire young people to realize their own dreams.
E.We enjoy a lot of convenience, thanks to the latest technology.

Goog morning, Ladies and gentleman. My topic is “________”.
Now in the 21st century, advertising is more and more important for people. Why? I think it is because through advertising, people, especially the businessmen, can introduce their products to the people all over the world. Because of this, many companies spend a lot of money on advertising. As we all know, there are many advertisements which are very interesting and popular. For example, Michael Jordan made an interesting advertisement for Nike. From this you can see how the companies make their products known to the world.
People can make a lot of money through advertising. It is known that many famous singers and movie stars make money in this way. However, I don’t think this is a good way for them to make money, because they are not the professional advertisers, especially those who advertise in medicine advertisements.
Nowadays, advertising not only means making the products known, but also means make ourselves known to people around us. Living today, we have to make people believe in us if we want to do important jobs. But how can this be done? We should first let other people know our good side: the good habits and abilities we have. In short, we should always remember to advertise ourselves to others. As I said before, advertising is not only important for companies but also for everyone, for all human beings. This is the most interesting thing about advertising.
1.The best topic to fill in the line in the first paragraph is “___________”.
A. The Importance of Advertising
B. Making Money through Advertising
C. Advertising Ourselves
D. Advice on Advertisements
2.This passage may be a (an) ____________.
A. advertisement B. story C. speech D. report
3.According to the passage, which of the following is not right?
A. Many companies are willing to spend money on advertising.
B. Advertising can make some people rich.
C. People can introduce their products through advertisements.
D. Advertising in not necessary for anyone.
