The world has a plastics problem. And not just with bottles. Straws (吸管), toothbrushes, toys—all kinds of plastics are placed in landfills. There are 5 billion tons of plastic waste in the world. Landfills have a large part of it. By 2050, they could have 13 billion tons.

    Much of plastic rubbish finds its way into the ocean. Scientists say 165 million tons of plastic pieces are floating around out there. And most plastic won't disappear itself. It will remain in the ocean forever. Whales get caught in plastic fishing nets. Birds die because of eating plastic straws and bottle caps. It endangers ocean life. Plastic rubbish even ends up in the food we eat.

    Governments are realizing that recycling may not be enough. They are taking more actions. Though it is hard work, it is still a solvable problem. In Britain, people are not allowed to use plastic bags except in hospitals. Scotland and several coastal cities in the US stop people from using plastic straws as well. The US alone throws away some 500 million plastic straws a day. That's enough to circle the Earth twice. "Saying no to a plastic straw is an easy way to make a big difference," Diana Lofflin who started www.strawfree.org said. "'Do we really want to pass on to our children a world harmed by plastic?"

    People have found some tasty ways to reduce waste. A company in India made the first-ever spoon that people can eat. You don't have to eat the spoon. You can throw it away. It decomposes (分解) in just a few days. David Edwards, a scientist at Harvard University, designed an eatable bag which can protect the food or drink inside. It is a delicious replacement for plastic ones.

Body language is animportant part ofcommunication. If you want to communicate well, it'simportant to know how to use your body to say what you mean, especially whenyou're in a foreign country.

If a person is bored, hewon't look at the person who is talking to him. He will find other things to do.He may also keep looking at his watch or a clock. If a person is open to you. hisarms and legs will not be crossed (交叉). And ifa person is relaxed, you will know it by looking at his body. even by hisslower breathing (呼吸).

These days, we easily feel stressed as the work we need to do grows more and more. It's important to know {#blank#}1{#/blank#} to solve problems and find ways to relax. 

First, we should try organizing our problems from most important to least important as well as most urgent(紧急的)to least urgent. If some problems are both important and urgent, do those things first. Once those are done, work on things {#blank#}2{#/blank#} are important but not urgent. After that, we can work on problems that are less important. In this way we can clearly know what to do first and not worrying about the rest, {#blank#}3{#/blank#} we might easily feel stressed out with so much work to do. 

Sometimes we are still under pressure after sorting out(分类)our work. That's OK. We can try to add some exercise to our weekly plan. It doesn't need to go on a big trip for several hours, although that surely helps. It could be something as small as walking around the neighborhood for ten to twenty {#blank#}4{#/blank#}.

Finally, we can try meditation(冥想). Again, it can be a simple thing. Just set ten to twenty minutes with an alarm, sit straight, close our eyes, and focus only on breathing, If other thoughts come up, accept that they are there and let them fly away on their own. 

By trying these steps, we will feel {#blank#}5{#/blank#} and peaceful when finishing all of the work. 

What are the Chinese astronauts' lives like? Do they do the same things in s_46 as we do on Earth?

The answer is yes. They do most of the things we do on Earth. But they do something [ʌn' ju:ʒuəl] {#blank#}1{#/blank#}. When their ship reaches a certain area, they can see the sun go up and down every 45 minutes. And they can have fun, too. They can s{#blank#}2{#/blank#} some time watching movies and talking to their families. In this way they will n{#blank#}3{#/blank#} feel bored.

Of course, they will do exercise to make sure that they will not get {#blank#}4{#/blank#}[ wi:k]. Because we can't send a doctor up there!

When it's time for sleep, astronauts have to sleep in bags. They t{#blank#}5{#/blank#} themselves to the bags so that they will not float away in their sleep.
