1 . Rainforests are home to a rich variety of medicinal plants, food, birds and animals. Can you believe that a single bush（灌木丛）in the Amazon may have more species of ants than the whole of Britain! About 480 varieties of trees may be found in just one hectare of rainforest.

Rainforests are the lungs of the planet-storing vast quantities of carbon dioxide and producing a significant amount of the world's oxygen. Rainforests have their own perfect system for ensuring their own survival; the tall trees make a canopy（树冠层）of branches and leaves which protect themselves, smaller plants, and the forest animals from heavy rain, intense dry heat from the sun and strong winds.

Amazingly, the trees grow in such a way that their leaves and branches, although close together, never actually touch those of another tree. Scientists think this is the plants' way to prevent the spread of any tree diseases and make life more difficult for leaf-eating insects like caterpillars. To survive in the forest, animals must climb, jump or fly across the gaps. The ground floor of the forest is not all tangled leaves and bushes, like in films, but is actually fairly clear. It is where dead leaves turn into food for the trees and other forest life.

They are not called rainforests for nothing! Rainforests can generate 75%of their own rain. At least 80 inches of rain a year is normal-and in some areas there may be as much as 430 inches of rain annually. This is real rain-your umbrella may protect you in a shower, but it won't keep you dry if there is a full rainstorm. In just two hours, streams can rise ten to twenty feet. The humidity（湿气）of large rainforests contributes to the formation of rainclouds that may travel to other countries in need of rain.

1. What can we learn about rainforests from the first paragraph?

A．They produce oxygen.	B．They cover a vast area.
C．They are well managed.	D．They are rich in wildlife.

2. Which of the following contributes most to the survival of rainforests?

A．Heavy rains	B．Big trees.
C．Small plants.	D．Forest animals.

3. Why do the leaves and branches of different trees avoid touching each other?

A．For more sunlight.	B．For more growing space.
C．For self-protection.	D．For the detection of insects.

4. What can be a suitable title for the text?

A．Life-Giving Rainforests	B．The Law of the Jungle
C．Animals in the Amazon	D．Weather in Rainforests

2 . When you think of the Arctic, you imagine an icy land of pure white snow, which is considered to be the last really clean place     1    (leave) on Earth. Yet plastic trash has now reached the remote regions of the Arctic and the Alps. A team of     2    (scientist) has discovered large quantities of microplastics(微塑料) — very small pieces of plastic waste — in the Arctic snow. While microplastics have been found in sea-water, drinking water, and even in animals over     3     past several years, this is the first study to show microplastics in snow,     4     indicates it is an airborne pollutant that must be paid attention to.

The researchers state that microplastics in snow suggest that microplastics may be in the air that we     5    (breath). Therefore, it is really important     6    (assess) if microplastics also reach lung tissues.

Previous research has found that they flow over long distances and into our oceans,     7    (damage) ecosystems along the way. They start in our wastewater, when we wash clothes     8     plastic fibers. The wastewater then flows into rivers and out to sea, where they     9    (eat) by sea animals. If people then eat these animals, it means that we’re     10    (probable) eating the plastic as well.

3 . An international group of coffee experts has considered Ethiopia’s coffee as the best in the world.Coffee is a top export (出口物) of the country. But at home, it is seen as national pride. Ethiopians feel good about their coffee, and enjoying a drink with friends is a long tradition.

Some people say the climate produces quality beans. Morton Wennersgarrd is a coffee importer. He said, “Ethiopia has different ancient types of coffee. They are planted in places with perfect soil, perfect altitude (海拔), and climates that are really suitable for coffee processing.”

Finding the best quality beans is often an issue of taste. The process is known as   cupping — tasting and comparing coffee from different roasted beans, grading and then pricing them. But before international experts come to taste, coffee beans are studied in small coffee laboratories. Helen Assefa, a lab technician, describes   the process, “When the coffee comes to the lab, we assess (评价) its quality first by recording the details.Then we weigh the moisture (水分) level and we examine the beans for analysis. After that we grind (磨碎) the coffee beans and taste the samples. In the end, we check for defective (有瑕疵的) beans.” Mubarik Abaoli is a lab worker.He says that testing is a very difficult and long process. “We select out the defects by hand. And we select out the defect according to the defect types.”

Ethiopia has got a lot of money by exporting coffee to more than 120 countries. The country has an export revenue (税收) of more than 840 million a year. But not all the best coffee leaves Ethiopia. Forty percent of the coffee grown in the country stays there. It remains an important part of everyday life at work, at home and at ceremonies.

2. The third paragraph is mainly about_______.

A．the ways of making coffee

3. What can we learn from the last paragraph?

A．More than 120 countries export coffee to Ethiopia.

B．Coffee plays an important role in Ethiopians’ life.

C．40% of the coffee grown in Ethiopia is exported.

D．Ethiopians earn their living by exporting coffee.

4. What is the main purpose of the passage?

A．To advertise the coffee in Ethiopia.

B．To comment on coffee experts’ work.

C．To introduce the best coffee in the world.

D．To recommend tourists activities in Ethiopia.

4 . Some Famous Libraries in the World
The Royal Library of Alexandria

The Royal Library of Alexandria in Alexandria, Egypt is probably known as the largest and the most famous library in the ancient world. It is said that the ancient library was burned three times over the centuries. A likeness of the ancient library was built in Alexandria and was opened on October 16，2002.

It used to be the third richest of ancient times in the world，which had more than 12,000 works of art, but it was destroyed in wars, leaving some ruins. Even so, it is now still so world-famous for its beautiful structure that many visitors come to see it. There is a statue of Athena at its entrance as she is the Goddess of Wisdom. It remains delicate and appealing.

Bodleian Library

Bodleian Library is attached to Oxford University and mainly used as a research library. It is also a copyright library, which means it has a right to every book published in the United Kingdom. The library was designed by the architect, Sir Giles Gilbert Scott. Construction was completed in 1940.

The British Library

The British Library was set up in 1973 and is one of the world’s greatest libraries. This library has PACCAR gallery of living and workshop of words.
