The great white shark（鲨鱼）is one of the most dangerous animals in the world. It can grow up to 7 meters long and weigh 2,100 kg. It has five rows of up to 3,000 very white, very sharp teeth. It needs them because the great white shark is a carnivore. It will eat almost anything that swims in the sea, from fish to dolphins to other sharks. Oh, and people, too. So, imagine how Rob Howes felt when he faced one of these terrifying animals off the northern coast of New Zealand.

Rob was swimming with his 15-year-old daughter, Niccy and two of her friends. They were enjoying the crystal-clear water when they noticed some dolphins（海豚）swimming up to them. It is not surprising to see dolphins in the waters there, and they often swim near humans. But these dolphins were not there for fun. They were swimming around the four humans in smaller and smaller circles. It seemed like they were gathering up the swimmers. Also, the dolphins were hitting their tails on the water. Were they trying to tell them something? That was when Rob saw the great white shark.

It was very close—only a few meters away. It wasn’t a big one, but at 3 meters long, it was big enough. It was swimming towards them, gliding through the water, but when it saw the dolphins, it turned and swam away. Rob realized that the dolphins had saved their lives. Had they known there was a shark nearby and decided to protect them? The dolphins followed the swimmers until they got safely back to shore（岸）. Rob and the others were very lucky that day. Some people pay lots of money to swim with dolphins. Rob swam with dolphins for free, but he also had a great white shark with him!

Over time, the cuckoo (布谷鸟) has learned to get other birds to care for its babies. The cuckoo is an amazing bird. Most birds lay their eggs and look after them until their babies hatch out. Then they feed their babies until they are ready to leave the nest.

Some birds are not such good parents. Cuckoos lay their eggs in the nest of other birds and do not care for their own babies. They get other birds to act as the parents. The other birds raise the young cuckoos as well as their own babies!

If the cuckoo egg hatches first, the baby cuckoo will often push the other eggs out of the nest so that it can get all the attention of its new mother. The young cuckoo sometimes even push the other babies out of the nest. The young cuckoo has a loud cry and is often bigger than the other baby birds, it will take all the food and the space in the nest.

If the cuckoo lay around 25 eggs each year in the nests of other birds. This means that many other birds spend all their time looking after young cuckoos instead of their own babies. Some birds have learned to recognize the cuckoos’ eggs and they push them out of their nests. But the cuckoos have also found ways of fooling (欺骗) the other birds. They can change their eggs to make them look just like the other birds’ own eggs.

Whether you’ve noticed it or not, fewer and fewer bees are around us now. About one quarter of the world’s 20,000 bee species (品种) have disappeared since 1990.

There are many reasons for that, including too much use of pesticides (杀虫剂), loss of plants and human activities that damage (破坏) their living places. But the main reason is the climate change, which is changing the bees’ environments in a faster way than they are able to get used to.

A map of where bees live across the world was just made by scientists from China and the US. To help people know about bees and protect them better, they tried to find out different species of bees in different areas. According to the map, there are more species of bees in the north half than in the south half of the earth, and more in dry warm areas than in wet forest areas.

In fact, bees are important contributors to humans and the whole world. When bees are flying from one place to another, they are helping many plants to pollinate (授粉). In other words, without bees, fresh fruit and vegetables would be fewer and fewer around the world. Therefore, we human should make our efforts to protect bees.

As for what to do to help, plant some plants to attract bees to your garden. If you see bees around you, take some photos and post them on the Internet so scientists can help find out where bees live and how bees move. We can come up with more ideas to save bee populations around the world.

30．How many bee species have disappeared since 1990?

A．About 5,000.          B．About 10,000.         C．About 20,000.        D．Over 20,000 .

31．Which is NOT a reason for the drop of bee population?

A．Wide use of pesticides.

B．Worse living places.

C．The fast climate change.

D．Fewer fresh fruit and vegetables.

32．Which does the bee map tell us?

A．Bees like living in wet places.

B．Bees are protected better than before.

C．Where different bee species live.

D．The south half of the earth has more bee species.

33．What does the underlined word “contributors” in paragraph 4 mean?

A．Makers                  B．Helpers                  C．Finders                  D．Carriers

34．What is the last paragraph about?

A．Ways of bee protection.

B．Changes of bees’ living environment.

C．Bee populations around the world.

D．The importance of protecting bee species.

D

A desert(沙漠) is a difficult place for animals to live, and some have unusual ways of making a living. The Texas lizard has a strange way to keep itself safe. When a predator(掠食动物) gets too close, blood goes out from the lizard’s eyes. Then it breathes in much air to make its body look bigger. Another interesting desert animal is the javelina. To make a predator afraid and run away, the javelina bravely faces the animal. It makes a big noise with its teeth. It raises the hard hairs on its back to make itself look bigger. The javelina also gives off a strong smell as a warning when it is afraid. This smell is so strong that javelinas are also called “smelly pigs”. Javelinas keep safe by staying close to their family, so there’s a good chance they can make a predator change its mind!

You might think a rain forest would be easier to live in than a desert. After all, there’s plenty of food and water in a rain forest. But that also means a lot of animals live there. Being able to climb trees is a useful skill in the rain forest. It allows an animal to keep away from predators. The sloth spends most of its life in the treetops. Its strong, curved claws(爪子) help it climb and hang upside down from branches. The sloth also moves very slowly. It does this so it’s not noticed. The aye-aye lives only in the rain forest of Madagascar, near Africa. The aye-aye is a night animal. This helps it to stay safe from daytime predators. However, the number of the aye-aye keeps going down and they may die out. People have hunted it because they think it brings bad luck. Also, much of the rain forest in Madagascar has been cut down, which has destroyed the aye-aye’s home. Today there are laws(法律) to keep people from killing it.

35．What is the passage mainly about?

A．What the animals in the desert look like.

B．How the animals in the rain forest find their food.

C．How the animals in the desert and in the rain forest stay safe.

D．What animals are in danger of losing their living environment.

36．How does a lizard protect itself when a predator gets too close?

A．It climbs trees.

B．It makes a big noise.

C．It gives off a strong smell.

D．Blood goes out from its eyes.

37．What can we learn from the passage?

A．The aye-aye is a welcome animal in Africa.

B．There is no food, no water and no danger in the desert.

C．The lizard and the javelina can make their bodies look bigger to keep safe.

D．It is really dangerous for the sloth to live in the forest no matter where it is.

After getting some information about dinosaurs from the encyclopedia (百科全书), Mary got interested in these animals. She surfed the Internet and found a lot more about dinosaurs. Here’s what she wrote in her notebook.

General information

Millions of years ago, long before there were any people, there were dinosaurs. They existed (存在) on earth for about 165 million years and suddenly died out (灭绝) 65 million years ago.

Fun facts

Size

The largest dinosaurs were more than 30 meters long and up to 15 meters tall.

The smallest dinosaurs were about the size of a chicken and had very long tails. They ate insects (昆虫).

Egg

Most dinosaurs were hatched (孵化) from eggs.

The biggest dinosaur egg ever found was the size of a football.

There were egg-eating dinosaurs that stole eggs from other dinosaurs’ nests (巢穴).

Brain

A lot of dinosaurs have big heads, but they didn’t have much brain inside. Most of the space was taken up with muscle (肌肉) and bones instead.

Tail

Dinosaurs that used their tails to beat their enemies had four feet and ate plants.

Dinosaurs that used their tails for balance (平衡) had two feet and two small arms, and they were often meat-eaters.

Discovery

From looking at bones, scientists can figure out (弄清楚) the shape of the dinosaur’s body.

There were more than 800 different kinds of dinosaurs.

Conclusion

We can only know about the lives of dinosaurs from the fossil (化石), eggs and footprints they left behind. But we still don’t know how they sounded, how they behaved, what colors they were and so on.

Oh, my God! Dinosaurs are the most mysterious animals in the world!
