Review
What does the passage talk about
Basketball was invented by a Canadian doctor in the 19th century. It
comes from a game that could be played in the winter on a hard floor.
The men were divided into two teams to play. They work together to get the ball in the other team’s basket. At the same time, they need to stop the competing team from getting the ball into their own basket.
In 1936 in Berlin, basketball became an event at the Olympics. Now it’s over 100 years old and is played by more than 100 million people in over 200 countries. It is enjoyed by many people for fun and exercise as a much-loved and active sport. The popularity of basketball has risen around the world, with many young people dreaming of becoming famous players.

Practice
Computer
Computers are becoming more and more important in our daily life. It is one of the most important inventions in the world. Do you know when the computer was invented
The computer was invented in 1946. At that time, it was huge. With the development of science and technology, the computer has grown smaller. Now there are many kinds of computers, such as personal computers and laptops. The computer is a very useful tool in our daily life. For example , it can send some messages to foreign friends by e-mail. What’s more, it can share information with others through the World Wide Web. We not only can listen to music but also play the game on computers. It makes us relax.
What a great invention! It’s hard to imagine what our life would be like without computers. I think computers will be more convenient and they are going to change our life completely in the near future. I hope there will be more high-technology products to make our life more convenient.
