A

Cows Contribute Global Warming Cows give us milk and meat, but they also make methane (甲烷) —agas that heats Earth 30 times faster than CO₂. One cow burps (打嗝) /farts (放屁) up to 300 liters daily! With 1.6 billion cows worldwide, this adds up fast. Scientists are trying new methods like feeding cows seaweed (海藻) to block methane, or making masks to catch cow burps. But seaweed tastes bad for cows, and masks make CO2. So, what’s the fix? Air Pollution Makes Life Harder Air pollution makes life harder for some insects and plants, a new study shows. Researchers at the University of Washington carried out tests with the evening primroses (月见草). At night, the pleasant smell of its flowers interacts (相互作用) with certain air pollutants. Key scent molecules (气味分子) are destroyed as a result. This makes it hard for insects as well as pollinators (传粉者) to find the flowers. The team shared its findings in Science. ________ Malaysia’s coral reefs (珊瑚礁), home to colourful sea life, are in danger. Too many tourists overcrowd islands during holidays, stepping on corals and leaving trash. Global warming worsens the problem—rising ocean temperatures cause coral bleaching (turning white and dying). Scientists warn these reefs might disappear soon if no action is taken.

 

1. In which SECTION of the newspaper can we see the materials?

A. ENVIRONMENT. B. TRAVEL.

C. PLANT. D. CHEMICAL.

2. What might the “fix” refer to?

A. A way that makes more milk and meat.

B. A method which creates more food for cows.

C. A mask which turns methane into CO₂.

D. A solution that stops cows from producing methane.

3. What is the finding of the researchers in the second piece of news?

A. The evening primroses are hardly seen at night.

B. The insects destroy the key scent molecules in flowers.

C. Air pollution makes it hard for insects to find the flowers.

D. Flowers fail to produce scent molecules at night.

4. The best heading for the third piece of news would be ________.

A. The Home to Colourful Sea Life

B. Malaysia’s Coral Reefs Are in Danger

C. Ocean Temperatures Are Rising

D. Tourists Should Take Action

B

①Can plants talk? Modern research has found something amazing: they do communicate with each other.

②When plants are eaten by bugs, they send out special chemicals from their leaves. This is like them saying, “Help, I’m in trouble!” Other plants get this message and then send out different chemicals. Scientists hope to learn more about this plant warning (警告) system, so that we can use it to grow more crops.

③More surprisingly, plants also use sound to communicate. People can’t hear these sounds; but plants are making them. Some plants make noises with their roots. Some trees make clicking noise, when there is not enough water.

④Plants can also talk to each other in a forest using a special system. Scientists call this system that the “wood wide web”. This system works underground with the help of fungi (霉菌)

connect different plants’ roots. It’s like a plant’s Internet. Plants can share messages and food through it. But sometimes, plants might use it to take food from others or hurt other plants with chemicals.

⑤Scientists are learning more every day about the secret (秘密的) ways in which plants talk to each other. Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves.

5. When plants are eaten by bugs, they will ________.

A. shout out they’re in trouble B. kill the insects by themselves

C. make chemicals as a call for helps D. ask other bugs to kill their enemies

6. With what do plants make noises to communicate?

A. Their roots. B. Their leaves. C. Their fruit. D. Their branches.

7. What do we know about the “wood wide web”?

A. It works above the ground. B. It may have some bad effects(影响).

C. It sends out special chemicals. D. It can carry water to different places.

8. How is the text organized? (①-Paragraph 1; ②-Paragraph 2…)

A.  B.  C.  D.

C

From September to February each year, Dazhong Mountain in Chuxiong, Yunnan is home to more than 50,000,000 migratory birds (候鸟). People used to call the mountain Daqueshan, which means bird-hunting mountain.
