【題目】The next time you take medicine when you’re ill, you may eat a cone snail(芋螺). At least that’s what some scientists are hoping. Scientists have found that cone snails can help with backache, as well as toothache and other body problems.

There are over 600 different kinds of cone snails. This family is especially found in warm and hot waters in the oceans. They catch and eat small fish and even other cone snails. The snails have venom that they’ll give out and use to kill small animals they have caught because cone snails are slow-moving. Sometimes the venom can even kill people. But some scientists have discovered that the venom can also be used as medicine.

The shells of cone snils are often brightly colored, and have interesting shapes, many people think the shells are so beautiful that people kill them, collect lots of shells, and sell them around the world. The environment is also very dangerous for them because of fishing and boating.

Scientists want to help save the cone snails. They hope to make new rules to stop them from dying. If they die out, scientists may never discover what kinds of medicines they can give us.

A. a warm river B. in a hot ocean

【題目】More than 50, 000, 000 people live in the rainforests of the world and most of them do not hurt the forest they live in. They eat the fruits that grow on the forest trees, but they do not cut them down. They kill some animals to eat, but they do not destroy them.

When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1, 000, 000 forest people in the Amazon forest. In 1980, there were only 200, 000.

The Yanomami live along the rivers of the rainforest in the north of Brazil(巴西). They have lived in the rainforest for about 10, 000 years and they use more than 2, 000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and more than 45, 000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made over a hundred airports. The Yanomami people lost land and food. Many died because new illnesses came to the forest with the strange people.

The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.

Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us—forest people, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.

In Brazil, people were cutting down the forest of local people to sell the wood. Local people tried to save their rainforest. They made blockades(障礙) across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.

In Panama (巴拿馬), local people also saved their forest. They made a rainforest park which tourists must spend money visiting.

【1】The number of the people living in the Amazon forest in 1980 was _______of that in 1900.

A. half B. one-third C. two-fifths D. one-fifth

【2】 The people who _______have destroyed the rainforest of the Yanomami.

A. made the roads and the airports

B. use plants for food and medicine

C. pick fruits and kill animals to eat

D. have lived there for about ten thousand years

【3】 Those people built roads and airports probably in order to_______.

A. carry the gold to other places

B. make people there live a better life

C. attract more tourists to the rainforests

D. stop the new illnesses from spreading

【4】In Panama, visitors have to_______ before they enter a forest park of local people.

A. plant trees

B. pay for the gold

C. pay for the tickets

D. make blockades across the roads

【5】From the article, we learn that _______.

A. to humans, gold is more important than trees

B. we mustn’t cut down any trees or kill any animals

C. we need wood to build houses, so we have to cut down/span> trees

D. the rainforest people have done something to protect their home

Draw a giraffe in your mind. How did you draw your giraffe? Does it have a long neck? Does it have long legs? Is it really tall? When people think of giraffes, they think of their long necks. A long neck and four long legs make the giraffe the tallest land animal on earth. A giraffe is 1.8m tall when it is born, and some giraffes get up to 6m tall when they are all grown up.

But did you know that giraffes also have long tongues? Have you seen the tongue of a giraffe before? A giraffe has a very long tongue which can hold and wrap (包) around objects. The tongue is designed for feeding, but it can be used in many different ways. For example, a giraffe can close its nose with its long tongue completely to keep out sand and dust. Also, a giraffe’s tongue is long enough to clean its owner’s ears as well!The tongue is black in colour to protect it from getting sunburnt (曬傷). It is nearly 56cm long. Giraffe only eat plants, and a full grown giraffe can eat 33kg of leaves a day. When giraffes look for some tall trees to eat, they sometimes fight with elephants for food. Giraffes use their tongue to eat leaves from some tall trees. The giraffe’s tongue is a helpful tool for reaching leaves and breaking off branches.

【題目】Look at the cat on the left. Find anything strange?

In 1961, a man found a strange cat on his farm in Scotland. The cat’s ears were folded（折著的）, bent（彎曲）forward, on its head. In fact, this was a new kind of cat. People named it the “Scottish Fold”.

The Scottish Fold has a round head and big eyes. Its neck and legs are short. They make it look very lovely. Interestingly, all the Scottish Folds are born with straight and unfolded ears. And when they are growing up day by day, some cats’ ears will begin to fold. So, the Scottish Fold comes in two types: folded ears and straight ears.

There is a nickname（昵稱）for the Scottish Fold. It is the “Messenger（信使）of Peace”. Why? Because the Folds can get along well with other cats. They are sweet and friendly animals. And unlike some other cats, they can even get along well with dogs! In many different places, for example, at a noisy house or in a cat show, you can see them playing with other animals happily.

Well, when you come to a new school, do you think it’s difficult to feel comfortable in the new place? Perhaps you can learn from the Scottish Fold, which is always sweet and friendly to others.

【1】The Scottish Fold .

A. is born with folded ears B. always has folded ears

【2】What does the Scottish Fold look like?

A. Because their ears are folded.

B. Because they look very cute.

C. Because they can stay at a noisy house or in a cat show.
