Around the late 1950s, you could hardly see a tree or a flower anywhere in Saihanba. In 1962, the government decided to change this dead land into a forest. To carry out the task, a group of 369 foresters, mostly in their 20s, was organised. "At the very beginning, I did not realise that the working conditions would be so harsh and the weather so bad," said Zhao Zhenyu, one of the first-generation foresters. But they never gave up. The foresters carried on, overcoming the challenges of the land. They used science and technology to help trees to survive harsh conditions. The Saihanba people worked hard with their hearts and minds for more than half a century. The Saihanba Spirit inspired the foresters to complete the difficult task. Saihanba is now the largest human-made forest in the world. It plays an important role in environmental protection. People can enjoy fresh air, birds singing, and beautiful scenery there. 根据短文内容，选择最佳答案。 1. What was Saihanba like in the late 1950s? A. A green forest B. A dead land with few trees C.

What makes this happen? People burn things like gas, oil, and coal. They cut down trees and create a lot of waste. These are major reasons for global warming. Global warming affects everything on the planet. It's like getting a fever. If we have a few degrees' increase in body temperature, we feel sick. The same goes for our planet. The effects of global warming are serious. For example, the snow and ice in the North Pole are starting to melt. This causes the sea level to rise, which can lead to more floods and storms. Thankfully, we can help slow down global warming by taking some simple actions. Instead of driving, we can choose to walk or bike. Turn off devices we aren't using like TVs and lights. Another great way to help is by planting trees in our community and doing other "green" activities. Just by making some small changes in our daily lives, we can play a role in addressing global warming. 根据短文内容，判断正 (T) 误 (F)。 6.
