Bamboo is a wonderful plant for many people around the world. 1 People make tables, clothes, medicine, and musical instruments with it. Pandas may eat bamboo every day, but people can also eat it.
2 Some bamboo grows so quickly that people say they can watch it grow. The speed of growth depends on the type of bamboo, the earth and the season. Normal bamboo grows 3—10 cm a day. It usually grows in tropical (热带的) areas. 3 Bamboo plants are found in Asia, Australia, parts of Africa, and South America.
One of the world’s oldest building materials is bamboo. Like today, people use it because it’s very strong. They used it to build houses, boats, and bridges. The Chinese made a bamboo bridge over the Min River in Sichuan, China almost 1000 years ago. 4 Also, bamboo is still used to make houses today, especially in China and Philippines.
As a part of history, bamboo is very important. The great scientist Thomas Edison did not invent the light bulb (灯泡), but he made it perfect. He wanted the material inside to burn for a long period of time. He tried over 1000 different types of materials. 5 One day, he tried to use a piece of bamboo and the light bulb lit up for over a thousand hours. This invention helped other scientists to make the modern light bulb we use today.

The Amazing Cactus
Cacti are special plants that mainly grow in deserts. Unlike most plants, they have thick stems instead of large leaves. These stems can store water, which is very important for living in dry places.
Cacti come in many shapes and sizes. Some are as small as a tennis ball, while others can grow up to 20 meters tall. Their flowers are usually bright—pink, yellow, or red—and bloom for a short time each year.
Why don’t cacti need much water One reason is their spines. Spines are like sharp needles that grow on the stems. They stop animals from eating the cactus and also reduce water loss by shading the plant.
People in desert areas use cacti in different ways. Some eat the fruit of certain cacti, which is sweet and juicy. Others use the stems to make medicine. But cacti are also in danger because of overcollecting and habitat loss.
1.Where do most cacti grow （ ）
A. In forests B. In deserts C. In rivers D. In mountains
2.What helps cacti store water （ ）

A. To help the plant grow taller B. To store extra water
C. To stop animals from eating the cactus D. To make the plant look beautiful
4.The underlined word “habitat” means ______ in Chinese. （ ）
