广东省佛山市顺德区2020-2021学年八年级下学期英语第7周教研联盟测试试卷

阅读短文,从每小题所给的四个选项中,选出能回答所提问题或完成所给句子的最佳答案。

    The water hyacinth(水葫芦) is one of the fastest growing water plants and it grows in many countries. It has beautiful purple-blue flowers but most people don't like it.

Millions of water hyacinths grow in rivers and lakes. Sometimes the plants become so thick that people can walk on them. People can't travel on boats on the water and they cannot fish in it. The plants also stop the water from moving. Then the water carries germs(细菌)that may make people and animals get ill. Farmers cannot use it to water their crops, either.

But now scientists think that water hyacinths can be useful. It is easy for these plants to grow. No one has to take care of them. They just grow and grow. So what can farmers use them to do? Some fish like to eat them. Farmers can grow these fish in the lakes and rivers with water hyacinths. Workers can collect and cut the plants with machines. Then they can use them to make their crops grow better. They can also feed their farm animals with them.

What's more, we know methane gas (沼气) can be made from plants. So it will be possible to make methane gas with water hyacinths. Then some poor countries will not have to buy the expensive petrol(石油).

Maybe in the future, people will love the water hyacinth instead of hating it.

(1)、What color are the flowers of the water hyacinth?
A、Pink. B、Yellow. C、Purple and blue. D、Black and white.
(2)、Paragraph 2 mainly tells us____ .
A、where water hyacinths live B、how water hyacinths grow in lakes C、why people hate water hyacinths D、what makes the water carry diseases
(3)、Which of the following shows the water hyacinth is useful?

①It grows very thick in rivers.

Later when I was a little older, my parents encouraged me to learn{#blank#}6{#/blank#}to write couplets. I became greatly interested in it. Every time when we{#blank#}7{#/blank#}relatives during the Spring Festival, I was always happy to collect the poems of their couplets. The poems are hopeful words. They{#blank#}8{#/blank#}good wishes like "health, wealth and longevity(长寿)".

Whether yellow, red or white, the onion is a vegetable that you may not know well. The list of its uses in cooking is endless. People have used onions to add flavor(味道) to their foods for thousands of years. Besides onions' great taste, they are very good for you. They have special chemicals(化学物质) that improve your ability to fight off sickness and you have fewer chances of getting a disease. 

No matter how good onions are for you, it is difficult to cut an onion without your eyes filling with tears! When you cut into an onion, irritating(刺激性的) chemicals inside the onion will get into the air. They touch your whole eyes and cause pain. Your eyes make tears to wash away the chemicals and protect your eyes. 

Luckily, cooks and scientists have discovered some ways to keep you from crying when you cut up onions:

Cut the onion under running water. The water will wash away the chemicals before they can reach your eyes. 

Use a fan to blow air over the onion as you cut it. The air will blow the chemicals away from your eyes. 

Put the onion in a fridge for an hour before cutting. This helps make the chemicals in the onion move slowly, so they may not ever reach your eyes. 

If you try out these good ideas and still cry while cutting onions, don't worry. Scientists think if you cut more onions, your body will become more resilient to the onion's chemicals. So the tears will not last long. If you think about how healthy onions are, you might even call those tears "happy tears".
