阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。

A

Have you ever heard of the “Queen of the Night”? It's not a person, but a very special cactus. This cactus blooms (开花) only one night each year, usually between June and July. Its large, white flowers open after sunset and close before sunrise. Because of this short blooming time, seeing it is a rare and exciting event for plant lovers.

The flower can be up to 30 centimeters long and smells very sweet to attract night-flying insects like moths for pollination (授粉). The plant itself is native to the deserts of southern Arizona and Mexico. It grows very slowly and needs very little water, just like other cacti.

People sometimes call it the “night-blooming cereus”. If you want to see it, you have to stay up late or get up very early. Many botanical gardens will have special “night viewing” events when they expect the cactus to bloom.

32. Why is the cactus called “Queen of the Night”?

A. Because it is the most beautiful cactus. B. Because it blooms only at night once a year. C. Because it is the queen of all plants. D. Because it was found by a queen.

33. How does the flower attract insects?

A. By its bright color. B. By its sweet smell. C. By its large size. D. By its short blooming time.

34. Where does this cactus naturally grow?

A. In Asian forests. B. In European gardens. C. In American deserts. D. In African grasslands.

35. What is the main purpose of the passage?

A. To tell a story about a queen. B. To introduce a special plant. C. To explain how cacti save water. D. To encourage people to visit gardens.

B

Elephants are amazing animals. They are the largest land animals on Earth. African elephants are larger than Asian elephants. They have bigger ears that look like the shape of Africa. Both male and female African elephants have long tusks (象牙).

Elephants are very intelligent. They have good memories and can remember places and other elephants for many years. They live in family groups led by an older female. They “talk” to each other with very low sounds that humans can't hear. They also show feelings like joy and sadness.

Sadly, elephants are in danger. People kill them for their ivory tusks. They also lose their homes because forests are cut down. Now there are much fewer elephants than before. Many countries are working hard to stop elephant hunting and protect their living areas. We can help by never buying anything made of ivory and supporting wildlife protection groups.

36. What is the difference between African and Asian elephants?

A. African elephants are smaller. B. Only African elephants have tusks. C. African elephants have bigger ears. D. Asian elephants live in larger groups.

37. What does the word “intelligent” in Paragraph 2 probably mean?

A. Large in size. B. Strong in body. C. Good at learning and understanding. D. Fast at running.

38. What is the main reason why elephants are endangered?

A. They have no food. B. They get sick easily. C. They are killed for ivory and lose homes. D. The weather is too hot for them.

39. How can we help protect elephants according to the passage?

A. By visiting them more often. B. By buying ivory products. C. By cutting down fewer trees. D. By not buying ivory and supporting protection groups.

40. What is the best title for the passage?

A. The Largest Animal in the World B. Let's Save the Intelligent Elephants C. The Difference Between Two Elephants D. Elephant Families in the Forest

Why are bees so important? You might think of them just as insects that make honey. 41 ______ In fact, they play a crucial role in our food supply.

Bees are the world's most important pollinators. When they fly from flower to flower to collect nectar (花蜜), pollen (花粉) sticks to their bodies. 42 ______ This process helps plants produce fruits, vegetables, and seeds. It is estimated that about one third of the food we eat depends on pollination, mostly by bees.

However, bee populations are declining worldwide. Scientists call this “Colony Collapse Disorder”. 43 ______ These include the use of pesticides (杀虫剂), loss of wildflower habitats, diseases, and climate change.

What happens if bees disappear? 44 ______ Many crops like apples, almonds, and blueberries would produce much less food. This would not only make these foods more expensive but could also lead to food shortages.

So, what can we do? We can plant bee-friendly flowers in our gardens or on our balconies. 45 ______ We can also buy honey from local beekeepers who take good care of their bees. Protecting bees means protecting our future food.

A. Then they carry it to the next flower.

B. The answer is simple: we would be in big trouble.

C. But their job as pollinators is even more important.

D. Bees are not the only pollinators in the world.

E. We should avoid using chemicals in our gardens.

F. This means many bee colonies are dying suddenly.

G. There are several reasons believed to cause this problem.

第一节

1. M: I think dolphins are very smart. They can learn many tricks.

W: Yes, but some scientists say elephants have better memories.

M: Really? Maybe dogs are the most intelligent because they understand us so well.

2. W: Look at those monkeys! They are playing in the trees.

M: And over there, the lions are sleeping in the sun.

W: Let's go to see the pandas next.

3. M: Do you like pandas?

W: Of course! They are so lovely with their black and white fur. But it's sad that they are endangered. We must protect them.

4. W: My sunflower grew 5 centimeters in just three days!

M: That's fast, but bamboo can grow much faster. I heard some types can grow over 30 centimeters in a day.

5. M: Many wild animals are losing their homes because forests are disappearing.

W: That's terrible. We should tell more people about this problem and ask them to help.

第二节

听第6段材料，回答第6、7题。

W: Hi, Tom. You look excited. What's up?

M: Hi, Lucy. I went hiking in the mountains last weekend. Guess what I saw?

W: Some beautiful flowers?

M: Even better! I saw a family of foxes! A mother fox with three little babies. They were so cute.

W: Wow, that's amazing! You are so lucky.

M: Yes, but I also felt a bit worried. I noticed that the forest there is much smaller than before. People are building houses nearby. I'm afraid the foxes will have nowhere to live soon.

听第7段材料，回答第8至10题。

M: Have you decided on the topic for your school biology project, Mary?

W: Not yet, John. The teacher said it should be about plants.

M: How about researching the oldest living plants? I read about a tree called the Great Basin Bristlecone Pine. Some of them are over 5,000 years old!

W: 5,000 years? That's older than the Egyptian pyramids! That sounds perfect. Are they the oldest?

M: Yes, they are considered the oldest non-clonal trees on Earth. They live in very harsh conditions in the mountains.

W: Great! I'll choose that. Now I need to find more information. I think I'll search online first and then go to the library for some books.

第三节

听下面一段独白。

Hello, everyone. Today, let's talk about some amazing animals and why they are important to our ecosystem. First, bees. They are famous for pollinating flowers. This helps plants grow fruits and seeds, which means more food for us and other animals. Second, earthworms. They live in the soil and make it richer by breaking down dead leaves. This is very good for planting. Third, birds. Many birds help by spreading seeds. When they eat fruits, the seeds pass through their bodies and grow in new places. This helps forests grow. Fourth, sharks. They are at the top of the ocean food chain. They keep the ocean ecosystem healthy by controlling the number of other fish. Last but not least, bats. They eat a lot of insects every night. This protects our crops from harmful insects. So, you see, every animal has its special role.

 Good morning, everyone!

 Today, I want to talk about my favorite animal, the elephant. Elephants are the largest land animals. They have long trunks and big ears. They are also very intelligent and have good memories. They live in family groups and care for each other.

 I like elephants because they are strong yet gentle. They play an important role in their ecosystem. Sadly, they are endangered because people hunt them for ivory and destroy their homes.

 We must take action to protect elephants and all other animals. We should never buy ivory products and support wildlife protection organizations. Remember, every living thing is important for a healthy planet.

 Thank you for listening!
