Camels are large animals living in dry areas. There are two species of camels; the Arabian camel with a single hump(驼背) from the dry desert areas of West Asia, and the Bactrian camel with two humps from Central and East Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years. Most camels are domesticated(驯化) and fed by people. Camels are plant-eaters.

Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees and chest. Camels have nostrils(鼻孔) that can open and close, protecting them from the desert environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth is extremely tough, allowing camels to eat thorny(带刺的) desert plants. Their widened feet help them move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the intense heat from desert sand. Their long legs help by keeping them further from the hot ground.

Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is commonly believed.The humps are actually a container of fat. Camels are incredibly well-adapted to their environment. When conditions heat up, camels can increase their own body temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day.

Camels are sometimes called “ships of the desert” because people ride them around the hot, dry deserts of the world. However, the number of camels is becoming smaller for various reasons.

1.According to the passage, camels usually live in ________.

A. Asia B. Africa

C. America D. Australia

2.Paragraph 2 is mainly about ________.

A. camels are useful animals

B. camels are clever animals

C. camels’ body structure and function

D. camels’ characteristics and habits

3.The reason why camels lose little water in deserts is that they ________.

A. get water from green foods

B. can adjust their temperature

C. store enough water in the humps

D. can manage without water

4.What will the author probably talk about following the last paragraph?

A. Ways to protect camels.

B. Habitats of camels.

C. Reasons for raising camels.

D. Functions of camels.

In the dry Namib Desert on the west coast of Africa, one type of beetle has found a special way of surviving. When the morning arrives, the Namib Beetle collects water drops on its bumpy(起伏不平的) back, then lets the water roll down into its mouth, allowing it to drink in an area without flowing water.

Shreerang Chhatre wants to use what nature has developed to help the world’s poor. Chhatre is an engineer at MIT who works on fog harvesting, the equipment that, like the beetle, attracts water drops. This way, poor villagers could collect clean water near their homes, instead of spending hours carrying water from distant wells or rivers.

Access to water is a serious global issue. According to the World Health Organization and UNICEF, nearly 900 million people worldwide live without safe drinking water. The burden of finding and transporting water falls heavily on women and children. “As a middle-class person, I think it’s terrible that the poor have to spend hours a day walking just to obtain a basic necessity,” Chhatre says.

A fog-harvesting machine consists of a fence-like mesh panel(网状面板), which attracts drops, connected to containers into which water falls. Chhatre has improved the materials used in these machines. He is continuing his work at MIT Sloan and the Legaturn Center in order to develop a workable business plan for applying fog-harvesting machines.

Interest in fog harvesting dates back to the 1990s, and has increased since new research on the Namib Beetle became famous in 2001. A few technologists saw potential in the concept for people. One Canadian charitable organization, FogQuest, has tested projects in Chile and Guatemala.

But fog harvesting remains in its childhood, technologically and commercially, as Chhatre readily recognizes. “It still faces some open problems,” he says. “But it’s a work in progress.” After all, the water that fills our rivers and lakes comes from air.

1.Which of the following is TRUE of Shreerang Chhatre?

A. He is an African engineer.

B. He is researching on the Namib Beetle.

C. He has made the first fog-harvesting machines to use.

D. He is trying to put fog-harvesting machines to use.

2.Why is Namib Beetle mentioned in the passage?

A. To describe the severe conditions in Namib Desert.

B. To introduce the diversity of species in Namib Desert.

C. To inform how animal nature can be used to benefit people.

D. To raise the awareness of accessing clean drinking water in poor areas.

3.The underlined word “it” in the last paragraph refers to _________.

A. UNICEF B. the beetle

C. fog harvesting D. a Canadian charitable organization

4.The author’s main purpose in writing the text is to ________.

A. stress the importance of saving water

B. show the Namib Beetle’s special way of surviving

C. introduce a new machine for collecting water from air

D. inform people of the serious water problem in Africa

Both men and women are living longer these days in industrialized countries.1.In general, they can expect to live six or seven years more than men. One reason for this is biological.

One important biological factor that helps women live longer is the difference in hormones(荷尔蒙)between men and women.  2.Between the ages of about 12 and 50, women produce hormones that are involved in fertility(生育能力). These hormones also have a positive effect on the heart and blood flow. In fact, women are less likely to have high blood pressure or to die from heart attacks.

3.They help the body defend itself against some kinds of infections. This means that women generally ger sick less often and less seriously than men. The common cold is a good example: women, on average, get fewer colds than men.

4.Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman’s body cells have a tendency(倾向)to age more slowly then a man’s. Others think that a man’s body cells have a tendency to age more quickly. 5.

A. However, women, on average, live longer.

B .The biological factor plays an important part.

C. Women are also helped by their female genes.

D. The female hormones also protect the body in another way.

E. Recent research seems to support both of these possibilities.

F. Therefore, women are more healthy than men and can live a better life.

G. Hormones are chemicals which are produced by the body to control carious body functions.
