If you were asked what your body is made of, probably you would say that it is made of flesh(肉體) and bones and covered with skin. You also know something about the blood which flows through it, and that there is a very important part which we call the brain.
But the flesh and the bones make up the largest part of the body, and there is a good deal to be learned about them. You know the general appearance of both flesh and bone from the parts of animals which you see in the butcher’s shop.
Bone is hard, and of a white color; indeed, it looks more like a piece of wood or stone than a part of a living animal. But bone is a real part of the living body, and it grows and is nourished (滋養(yǎng))just as the body is. If a man breaks the bone of his arm or his leg, it is firmly bound up, to prevent the broken parts from moving out of the proper places, and in time then bone grows together again and becomes quite strong.
The bones are fastened together by various kinds of joints(關(guān)節(jié)). They form the framework of the body, and give it strength to retain its proper shape. This framework is called the skeleton(骨架). Some animals, such as worms and slugs, have no skeleton; and others, such as shellfish, have a kind of hard covering or skeleton outside.
The most important part of the skeleton is the backbone. It is so important that naturalists divide all animals into two classes,--- those which have a backbone and those which have none. All the higher animals, including man, have a backbone, or vertebral column as it is called. They are therefore called vertebrate (脊椎的)animals. The others are called invertebrate animals.
1.What’s our body made of?
A. Flesh
B. Flesh and bones.
C. Flesh, bones and flood.
D. Flesh, bones, flood and brain.
2.Where can we see flesh and bones from the parts of animals?
A. In the bookshop. B In the butchers’ shop.
C. At home. D. In the shopping mall
3.Why should the bones bound up firmly if they were broken?
A.To make the bones strong
B. To protect our arms and legs
C. To fasten the joints.
D. To prevent the broken parts from moving out of the proper places.
4. From the passage, we know higher animals are called .
A. backbone B. human beings

任務(wù)型閱讀
Many kinds of birds live in the USA, but the number of them is becoming smaller every year. It is mainly because of pet cats.
Of the 90 million pet cats in this country, about two-thirds are allowed to go outside. It is said that these cats kill millions of birds each year, as well as other animals. They can also bring illness to the animals that live in people’s garden, further weakening the health of the natural populations. Allowing pet cats to go outside is not just bad for birds and wildlife, it is also bad for the cats themselves. Outdoor cats can get sick very easily. They are in danger from traffic and attacks(襲擊) from other animals. In fact, outdoor cats usually don’t live past the age of five, while indoor cats often live to be 17 or older.
Keep your pet cat inside! If you raise a young cat, it’s your duty to let it play inside.

A young girl sits at her desk, reviewing her homework for the evening. English: Read three chapters and write a report. Math: Complete 30 problems. Science: Do a worksheet, front and back. French: Study new words for tomorrow’s test. It’s going to be a long night.
This happens to students in America. Now it’s time to start a homework revolution(變革).
According to the National Education Association, a student should be assigned (布置) no more than 10 minutes per grade level per night. For example, a first grader should only have 10 minutes of homework, a second-grader, 20 minutes, and so on. This means that a student in my grade—seventh—should have no more than 70 minutes of work each night. Yet this is often doubled, sometimes even worse!
It’s no good giving students too much homework. According to research, kids are developing more illness at school, such as stomachaches, headaches and sleep problems than before.
Some teachers assign more homework, but they are not the only ones to blame. “Many teachers are under greater pressure than ever before,” says Kylene Beers, President of the National Council for teachers of English, “Some of it comes from parents, some from the wish for high scores on tests.” Teachers who are under pressure feel the need to assign more homework.
Some people have different ideas, saying that homework prepares kids for doing better in high school, better in college, and getting better job in the future. But too much homework is sapping students’ strength, curiosity(削弱學(xué)生的個性和好奇心), and most importantly, their love of learning, is that really what teachers and parents want?
