1 . Blue Planet II’s latest episode focuses on how plastic is having a disastrous effect on the ocean and slowly poisoning our sea creatures. Researchers recently also found that sea creatures living in the deepest place on Earth, the Mariana Trench, have plastic in their stomachs. Indeed, the oceans are drowning in plastic.

Though it seems now that the world couldn’t possibly function without plastics, consumer plastics are a remarkably recent invention. The first plastic bags were introduced in the 1950s;   the same decade that plastic packaging began gaining in popularity in the United States. This growth has happened so fast that science is still catching up with the change. Plastics pollution research, for instance, is still a very early science.

We put all these plastics into the environment and we still don’t really know what the outcomes are going to be. What we do know, though, is disturbing. Ocean plastic is estimated to kill millions of marine animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. One in three leatherback turtles, which often mistake plastic bags for jellyfish, have been found with plastic in their bellies. Ninety percent of seabirds are now eating plastics on a regular basis. By 2050, that figure is expected to rise to 100 percent.

And it’s not just wildlife that is threatened by the plastics in our seas. Humans are consuming plastics through the seafood we eat. I could understand why some people see ocean plastic as a disaster, worth mentioning to the same degree as climate change. But ocean plastic is not as complicated as climate change. There are no ocean trash deniers (否认者), at least so far. To do something about it, we don’t have to remake our planet energy system.

This is not a problem where we don’t know what the solution is. We know how to pick up garbage. Anyone can do it. We know how to dispose (处理) of it. We know how to recycle. We can all start by thinking twice before we use single-use plastic products. Things that may seem ordinary, like using a reusable bottle or a reusable bag----when taken collectively, these choices really do make a difference.

3 . Would you know what to do if a fire started in your home? Take the time now to review the following safety tips, and your family will be prepared in time of a fire in your home:

    1    

An escape plan can help every member of a family get out of a burning house. The idea is to get outside quickly and safely.     2     So it is important to learn and remember the different ways out of your home.

Stay low

If you can see smoke in the house, stay low to the ground as you make your way to the exit.       3     You will breathe less smoke if you stay to the ground. Smoke naturally rises, so if there is smoke while you are using your escape route，staying low means you can crawl (爬) under most of it.

What if you can’t get out right away?

If you can’t get out fast because fire or smoke is stopping an escape route, you will want to yell for help. You can do this from an open window or call 911 if you have a phone with you.     4     Then, firefighters will have a hard time finding you. The sooner they find you, the sooner you both can get out.

If your clothes catch fire, what should you do?

Your clothes could catch fire during a fire or by accident if you step too close to a candle. If this happens, don’t run! Instead, stop, drop to the ground, cover your face with your hands, and roll. This will cut off the air and put out the flames.     5    

A．An easy way to remember this is: Stop, Drop, and Roll!

B．Smoke from a fire can make it hard to see where things are.

C．Preventing fires is in the first place!

D．Know your way out

E．They will help prepare you for what you need to do in case of a fire.

F．Even if you are scared, never hide under the bed or in a closet.

G．In a fire, smoke and poisonous (有毒的) air hurt more people, than the actual flames (火焰) do.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Diets have changed in China — and so too has its top crop. Since 2011, the country     1    （grow）more corn than rice. Corn production has jumped nearly 125 percent over     2     past 25 years, while rice has increased only 7 percent.

A taste for meat is     3     (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice     4     (improve) water quality. Corn uses less water     5     rice and creates less fertilizer(化肥) runoff. This switch has decreased     6     (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

According to the World Bank, China accounts for about 30 percent of total     7     (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government     8     (start) a soil-testing program     9     gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while     10     (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.

Last Sunday I saw a worst storm in years. It came sudden and went on for over three hours. After lunch, I went into my room to have a rest. The air was hot, but all was quiet. Then a strong wind started to blow into my room. Pieces of paper on my desk flew high into the air and some flew out the open window. As I ran out to catch it, big drop of rain began to fall. When I come back into my house, it was raining more harder and harder. Then I heard a loud crashing sound from the back of the house. When I ran out of my room to find out that had happened, a big tree had fallen down and broke the top of the backroom.
