五、阅读理解(每小题2分，共8分)
①Can plants talk？ Modern research has found something amazing： They do communicate with each other.
②It has been known for some time that plants use chemicals to communicate with each other. This happens when a plant gets attacked by insects. The plant gives out chemicals from the leaves that are being eaten.1 When another plant gets the chemicals，it starts to give out its own，different chemicals. Some of these chemicals drive insects away. Others attract the wasps (吸引黄蜂)!1 The wasps kill the insects that are eating the plants. Scientists hope to learn more about this plant warning system，so that we can use it to grow more crops.
③More surprisingly，plants also use sounds to communicate. People can’t hear these sounds，but plants are making them. Some plants make noises with their roots. Some trees make clicking noises when there is not enough water.
④Most surprisingly of all，plants have an amazing system of communication. The system can link (连接) nearly every plant in a forest. Scientists call this system the “wood wide web”. It is in some ways similar to the Internet we use. Using
the wood wide web，plants can share information and even food with each other. However，it may lead to bad effects. Plants may use it to steal food from each other，or spread chemicals to attack other plants. Perhaps one day scientists will learn how to create a “firewall” to help avoid these attacks within the wood wide web.
⑤Scientists are learning more every day about the secret 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.2
(　　)1.What will plants do when they are attacked by insects？
A.They will kill the insects by themselves.
B.They will make the wasps to kill the insects.
C.They will send out signals to ask for help.
D.They will produce chemicals as a warning or a call for help.
(　　)2.What is the writer’s purpose of the last paragraph？
A.To give people hope for further studies.
B.To praise (表扬) scientists for their great achievements.
C.To call on people to protect the plants on earth.
D.To encourage people to communicate with plants.

　　Do you know how deep the sea is？ What does it look like？ What kind of animals are living there？1 More than 80% of the sea hasn’t been studied yet! Looking carefully at the deep sea is hard because it’s dark，cold，and the pressure is strong. Although there are challenges，scientists have still been able to research parts of the deep sea. One way is by using small tools called submersibles (潜水器). These tools record videos and collect samples of the water and seafloor.
What scientists have found so far from their research is pretty amazing! The deep sea is home to animals that adapt (适应) to such dark and cold places in cool ways. Some animals have large eyes to take in light. Others are blind and smell things around to live.2 Many deep-sea animals can even make their own light. The female angler fish uses bacteria (细菌) to make light in order to catch food.
Vents are another part of the deep sea we’re learning about. They are home to some small sea animals.
Scientists are working to study more of the deep sea. In these dark，high-pressure places，they hardly find animals like fish or whales because their bodies would break into pieces under the strong water pressure. But each year they discover new kinds of sea animals. No matter what they discover next，one thing is sure — it will surprise us all!3
(　　)1.How does the writer lead into the topic in Paragraph 1？
A.By asking questions. B.By telling stories.
C.By listing numbers. D.By comparing facts.

B.It’s too difficult to find animals.

Bigfoot is one of the most famous mysteries of nature. People say it is a large，hairy creature (生物). It walks upright like a human，standing over 3 metres tall with wide shoulders. Its name comes from the huge footprints — up to 35 centimetres long. 1.____________ Such stories have been told for hundreds of years，especially by Native American groups in North America.
B

Some even said they heard deep growls (咆哮) or loud calls before catching a quick look at it.
C
Scientists have different ideas about Bigfoot. Many think the reports are either mistakes or made-up stories. They say people might have seen bears or other large animals and thought they were Bigfoot.3.____________ They think it’s possible that scientists haven’t found this animal yet.
4.____________ Whether it is real or not，Bigfoot remains something that makes people curious about nature’s secrets，encouraging us to learn more about the world around us.

五、阅读理解(每小题2分，共8分)
Animals grow old，just like humans. What do you think of older wild animals？ Are they important to their groups？1 A new study has found that protecting older wild animals is very important because they have knowledge to help other members survive (生存).
　▲　 When older birds have baby birds，they are better at providing food and finding a good place to live.2 This makes it more likely for the babies to survive. Older elephants are good at remembering which animals are friendly and which ones aren’t. They are also better at knowing possible dangers.2 Grandmother orcas (killer whales) use their knowledge to help their families find food when there’s not much around.
Older animals face serious problems in some parts of the world. For example，fishing has caused the number of older fish to fall greatly. In some places，because poaching is common，more older animals are at risk than young ones.3
The researchers，from Charles Darwin University in Australia，said humans must do more to make sure that enough old animals survive. They’ve asked the International Union for Conservation of Nature to help researchers come up with ways to protect those at risk. They also said that we should try to stop catching too many old fish to protect them.
