In 1987, a small company names Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world's second-largest maker of smartphones behind Korea's Samsung. It has also become the world's largest supplier(供应商) of 5G.

    But recently, Huawei faced some difficulties. The U.S. government ordered a ban() on its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the U.S. government planned to stop selling parts and services to Huawei, which was believed that Huawei's business would be hurt.

    ＂We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information.＂ Ren Zhengfei, Huawei's founder and president said. ＂This ban from the U.S. would have little effect on our company. Huawei has enough ability to deal with the problems.＂ Ren added.

    In an interview several years ago, Ren Zhengfei said, ＂I started Huawei with only ￡4,000 at the beginning, but now it has become a $100 billion company. The experience was not as romantic(浪漫的) as you imagine.＂

    Facing the ban of the U.S., Huawei is growing. Huawei's smartphone sales around the world rose 50 percent compared to a year earlier in the first three months of 2019. At the same time ,sales from both Samsung and Apple fell. So far, Huawei has grown into the world's largest telecommunications equipment(电信设备) supplier, selling in17 O countries! It may beat Samsung as the largest smartphone maker in the near future.

    Can you imagine that we could build a beautiful city with rubbish? Maybe you will think it is 1. However, it can be true! Nothing is a waste if we have a creative mind. Let me show you something about 2 rubbish.

    Sometimes we can see tons of rubbish in the streets, on the roads, near the buildings here and there. Many large cities became so ugly 3 it. Nobody likes rubbish, but in fact, some rubbish can be used again. All of us want to solve the problem, we must do something to 4 rubbish. We should take action from now on. 5, some good things will not be wasted.

    Do you often throw away things you don't need any more? Have you ever thought about how these things can actually be put to good use? For Example, when a car gets too old, it may not run any more. But we can use the metal of the car to make something else. When a bottle is empty, it 6 as waste. You don't know bottle glass can be made into sand and used to build streets. Rubbish 7 food can be changed into fertilizer to make plants grow better. It is cheap and safe. And other rubbish can also be used to make building blocks. Now, 8 machines are designed for that.

    9, people will watch films in a beautiful cinema which is built out of rubbish. Besides buildings and roads, cities may be made from rubbish. But so far, building beautiful cities made from rubbish is only 10.

    It's March 12^th. Li Li and Lin Tao are digging on a hill nor far from their school. In China, people across the country plant trees 1 on this day.

    The idea of planting trees was first put forward in 1911 by Sun Zhongshan, the great 2 in China's history. He said more trees were needed as a 3 against flood(洪水)and drought. In 1915, April 5^th was named as Tree Planting Day.Then, in 1979, the day 4 to March 12^th, to 5 the date on which Sun Zhongshan died.

    ＂Everyone has heard of the Great Wall of China,＂says Li Li. ＂But have you heard of the Green Wall of China? That's the biggest tree planting 6 of all. ＂The Gobi Desert in the north of China was 7 every year. So in 1978, a tree planting project was started to 8 Gobi spreading. The government and local farmers have been planting millions of trees to build a great green＂wall＂ along the edge of the desert.

    ＂Tree planting has become a tradition in China now,＂says Lin Tao. ＂Almost everyone does it on March 12th. Many people also plant a tree on a 9 day. My parents planted a tree when started school. And my cousin planted 10 on his wedding (婚礼) day. We do it for the environment and for ourselves.＂
