【題目】 School backpacks have been a hot topic in China recently. Some Chinese parents buy hardcover school backpacks from Japan, although they can be as expensive as 5,000 yuan, according to Chinese newspaper Urban Express. These backpacks are popular because the hard cover helps hold books in place. This can help kids keep their balance and protect their spines(脊柱). But it turns out that the bags can barely fit in the students’ desks.

A good backpack is important for children’s health. “It can relieve (減輕) pressure from the shoulders,” says Dr Rob Danoff from the US. He also says students need a backpack that’s made for the child’s size. Cushioned (加墊的) backs and shoulder straps (帶子) will help them avoid pain.

However, the biggest problem for school backpacks is that they are too heavy, noted Hou Weiguang, a doctor in Chengdu. In China, students have many textbooks and exercise books. The weight makes many kids suffer from side-bending (側(cè)彎的) spines, Hou said. He suggests that a backpack should be no more than 15 percent of a child’s body weight to avoid pain or injury.

Parents need to make sure their kids only carry what they need. Schools and governments need to help too, added Zheng Yongshun, an education official from Hong Kong. He said schools should offer locker (儲物柜) space and shared books so kids can carry fewer books.

【1】Why are hardcover school backpacks popular?

【3】If a student weighs 50kg, how heavy should a backpack be?

【4】主旨題。最后一段意思是“父母需要確保他們的孩子只帶他們需要的東西。香港的教育官員鄭永舜補充說，學(xué)校和政府也需要幫助。他說，學(xué)校應(yīng)該提供儲物柜（locker）和共享圖書的空間，這樣孩子們就可以少帶書了�！笨芍白詈笠欢问顷P(guān)于如何減輕背包重量的建議�！惫蔬xB。

【題目】 A material is what something is made of. There are 5 basic materials. Most things are made with these materials. Some things are made of metal. Some things are made of glass. Some things are made of wood. Some things are made of cloth. And some things are made of plastic.

There are some other materials. But they are not used as much as these 5 materials.

Let's talk about metal first. Metal is very heavy. And it is very hard and strong. It usually feels cool if you touch it. We use metal to make lots of things. We use it for forks and knives. We use it for keys. We use it for cars. We use it for these things because it is very strong.

Next, let's talk about glass. Glass is very smooth. It feels cool to touch. It is not as heavy as metal. It is hard. But it is not strong. It breaks very easily! Then why do we use it? We use it because it is clear! You can see through glass! That's why we use it for windows. That's also why we use it for glasses.

Now, let's talk about wood. Wood is lighter than metal and glass. It is not as strong as metal. But it is much stronger than glass. We use wood to make lots of things. Things made of wood are usually light and hard and strong. Chairs and tables are made of wood. Pencils are made of wood.

Now let's talk about cloth. Cloth is very light. It is much lighter than wood. And it is very soft. We use cloth to make lots of things. For example, it is used to make clothing. And it is used to make blankets.

Last, let's talk about plastic. Plastic is also very light. But it is different from cloth.

Sometimes it is soft. And sometimes it is hard. Plastic can be used to make thin plastic bags. These are light, soft, and strong. But plastic can also be used to make bicycle helmets. These are light, hard, and strong. A helmet and a bag seem different. But they are both made from plastic.

【1】Which sentence from the passage best describes the main idea?

A."We use cloth to make lots of things.”B."Metal is very heavy."
