【推荐2】What will the weather be like? Some people say they can know what the weather will be like from the animals. They believe that birds, chickens and frogs can tell the weather.

When they see birds fly high (高的) out to the sea, they know it is a nice day, because birds won't fly out when it's rainy. When the weather becomes bad, the birds will come back to the beach. A big wind may come with a rain. Birds do not like to fly in a big wind. They may sit in a tree when rain is coming. Chickens aren't quiet when it is going to rain, and they are running here and there. Frogs (青蛙) are making a big noise in the pool. If it is a nice day, the frogs will come out of the water.

When the whale was found on the island, it was already decomposing when animal doctors arrived. So they were unable to be sure if the plastic caused its death, said Lukas, the leader of the World Wildlife Fund in Indonesia. The plastic weighed about 6 kilograms, or 13 pounds, he said.

But pictures of the dead whale caused a warm discussion. The people in the country have started to realize that it is because of using too much plastic. So has the government. Indonesia, a nation of about 260 million people was the world’s second-biggest producer of plastic waste in 2018, behind only China.

If the whales eat too much plastic, they will have a wrong feeling. They think that they are full. And that will lead them to eat less food that provides all the good things they need, said Nicholas who is the leader of the Ocean Conservancy. Moreover, eating too much plastic can make them reduce their weight, their energy and slow down their swimming. As a result, whales are easier to be hurt by the sharks and many other dangerous animals in the sea.

More than 800 kinds of animals in the sea are affected by about 8.8 million tons of plastic which is thrown away freely in the ocean each year. Plastic can also stop the animals moving freely and sometimes they will cause them to die because they have to be under the water for too long. Some plastic can make a small hole in their stomachs after they eat it.

How to keep the memory? Our English teacher, Miss Wang, has taught us a good way of remember things to make our own yearbook. What is a yearbook? A yearbook is a kind of book which is used to keep the memory of exciting moments. It's usually made at the end of the year.

Last December, we began to make our yearbook. First, we chose the persons who had done something special, then some students interviewed them. Some wrote down their stories, others took photos of them. Finally, our teacher helped us to put the things together. Everyone in our class had something to do. We had our first yearbook.

All of us put a lot of love into making the yearbook. It is so wonderful that not only the students but also our parents and teachers will remember the special time for ever.

【推荐2】The new height of Mount Qomolangma is 8,848.86 meters. The result was announced by China and Nepal together on December 8, 2020. The two countries called the mountain “an important symbol of the friendship between Nepal and China”.

A team of Chinese surveyors climbed the mountain on May 27, 2020. They remained at the peak（峰顶）for nearly two and a half hours. This was a new record for Chinese climbers. Some Nepalese surveyors reached the top of the mountain in May, 2019 to carry out measurements（测量）. The two countries reached an agreement on the height of the mountain before the announcement.

In 1975, Chinese surveyors measured Mount Qomolangma as standing 8,848.13 meters above sea level. During that survey, the Chinese team put a survey marker（测标）up on top of the peak for the first time. Another Chinese survey suggested that the mountain’s height may have changed after a 7.8-magnitude（震级）earthquake hit Nepal in 2015, comparing with that of 8,844.43 meters in 2005.
