“Small enough to fit in your hands but too dangerous to hold” is a good description of the hedgehog. Though small, it is able to protect itself from attack or harm. Thousands of stiff, sharp spines cover the animal’s back and sides. Even though spines provide the hedgehog with effective protection, the animal’s most striking characteristic is its practice of curling up into a tight ball, with its spines sticking out in all directions. The hedgehog curls up if disturbed or frightened—only the strongest animals can open it. It also sleeps in this position, so it is rarely caught unprotected.

Hedgehogs can live in a wide range of climates and lands in East Africa. They must have dry shelters on well-drained soil and a good supply of insects. Nairobi, the capital of Kenya in East Africa, meets these habitat conditions, where hedgehogs are reported to be abundant. A hedgehog uses a small home range with an approximate 120-yard radius (半径范围) from its nest. The hedgehog makes loud noises if its range is invaded by another animal.

The hedgehog wakes up at dusk and begins its activities alone. It uses regular pathways, walking along on its short legs searching for food. A hedgehog will eat about one-third of its body weight in one night. Its favorite foods are insects, earthworms and snails, making it a welcome guest in many gardens—it is even kept as a pet. It is also known to eat eggs, small mammals, birds, frogs, reptiles, and roots. Although not completely immune to poison, hedgehogs have enough resistance to allow them to eat poisonous snakes.

1.While facing danger, the hedgehog ________.

A.stands straight up B.makes loud noises

C.goes back to its nest D.uses its spines for protection

2.The second paragraph is mainly about hedgehog’s ________.

A.appearance B.habitat C.diet D.hunting skills

3.According to paragraph 3, the hedgehog is ________.

A.active at night B.afraid of snakes

C.keeping away from gardens D.totally immune to poisons

4.It can be inferred from the text that ________.

A.there is a lot of rain in Nairobi

B.hedgehogs are cooperative animals

C.hedgehogs always stay on guard against danger

D.there is an increasing trend towards keeping pet hedgehogs

When we say older people shrink, we don’t mean they become tiny enough to fit in your pocket! We just mean that it’s common for older people to become a little shorter over time. This kind of shrinking can’t be reversed, although people can slow or stop this process. But why does shrinking happen at all?

Because of gravity (that force that keeps your feet on the ground) , cushions between the bones in the spine (脊骨), get compressed (压缩), which makes a person lose a little height and become shorter.

Another reason why some older people shrink is because of osteoporosis (骨质疏松). Osteoporosis occurs when bone is broken down and not enough new bone material is made. Over time, bone is said to be lost because it’s not being replaced. Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.

Older people — especially women, who generally have smaller and lighter bones to begin with — are more likely to develop osteoporosis. As years go by, a person with osteoporosis can get small breaks in bones that are called compression fractures. These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over (驼背).

Did you know that every day you shrink a little, too? You aren’t as tall at the end of the day as you are at the beginning. That’s because as the day goes on, water in the disks of the spine gets compressed due to gravity, making you just a tiny bit shorter. Don’t worry, though. Once you get a good night’s rest, your body recovers, and the next morning, you’re standing tall again!

Smoking and drinking alcohol can make this problem worse. Want to do something right now to build strong bones? I believe what I say will help you.

1.Which of the following statements is true?

A．For shrinking, people can do nothing about it.

B．If someone is injured, he will become shorter.

C．Women have smaller and lighter bones than men.

D．We aren’t as tall at the end of the day as we are at the beginning.

2.What should we do if we don’t want to shrink faster?

A．We should try to reduce gravity.

B．We should be careful not to be hurt by others.

C．We should sleep as long as possible.

D．We should keep away from smoking and drinking alcohol.

3.What is the topic of the passage?

A．How can we stop shrinking?

B．Why do we shrink?

C．Some tips on how to keep tall.

D．How to live a healthy life.

4.About osteoporosis we know that _______.

A．gravity is one of the causes of osteoporosis

B．once our bone is broken down, osteoporosis will occur

C．women are more likely to develop osteoporosis

D．if we develop osteoporosis, we are more likely to be shorter

5.What will the author talk about in the paragraph to be followed?

A．Tell us how to grow taller.

B．Tell us how to become healthier.

C．Tell us how to avoid being shrinking.

D．Tell us what to do to have strong bones.

Every living cell contains genes. They are too small to be seen in a microscope, but they are very important. Each set of genes in the body contains all the instructions needed to make a human being. Some genes determine hair color. Some determine the shape of a nose. Some genes help determine your height and even your weight.

Genes are made of a chemical called DNA-the letters stand for deoxyribonucleic acid(脱氧核糖核酸). In the early 1950's, two scientists, Francis Crick and James Watson, figured out how the parts of DNA fit together. Once scientists understood this structure, it became possible to take pieces of DNA apart and put them together in new ways. New kinds of genes could be made in this manner.

Scientists have studied the genes of many plants and animals. They have worked out which genes affect the color of a tomato and the thickness of its skin. Working out which genes determine which features is called genetic mapping, scientists have begun the Human Genome Project, an ambitious effort to map all the genes in the human body.

Some genes may be defective(有缺陷的). For example, something might be wrong with the gene that makes blood clot(凝聚). A baby born with this defective gene could suffer serious hemorrhages(出血) or even bleed to death because his or her blood fails to clot. If scientists ever learn how to map all the genes in our bodies, they can determine whether or not an unborn child has any defective genes. They might even discover how to treat these genes before the child is born.

1.What was the achievement of Francis Crick and James Watson?

A. They discovered why people have different hair colors.

B. They learned that some people bleed for long periods of time.

C. They looked at human cells under the microscope.

D. They worked out the structure of DNA.

2.What is the main idea of this passage?

A. Defective genes can never be repaired.

B. Genes are too small to be seen through a microscope.

C. Genes help scientists understand how living things develop their characteristics.

D. The Human Genome Project may explain the role of every gene in the body.
