Why must we pay taxes? The answer is that the government needs money for many things, for example to pay its soldiers, sailors and airmen, to build roads, bridges, offices, schools, etc and to buy goods from abroad; and only the people of the country can supply the money．One of the most important taxes is income-tax which a person pays according to the amount of his income-tax．Whether he is a businessman, a doctor, a lawyer, a shopkeeper, a miner, or anything else．This is called a “direct” tax, because it is paid in money direct to the government．

Another tax is paid on goods such as watches, jewellery, new clothes, tobacco, wine, etc, when they are brought into a country, such a tax is paid as part of the price of these goods if they are later sold in shops．We call it “indirect” tax, because it is paid indirectly through the shopkeeper．

People usually complain about having to pay taxes, but they forget that the money is spent on the things that they and their families need．We need policemen to catch thieves, to see that men obey the laws, to direct traffic, etc, and they must be paid what they earn; children need education and there must be schools and teachers; we want our streets to be kept clean, and the wages of men who do this kind of work have to be paid．Above all, the country must always be ready to defend itself against attacking enemies, and we cannot have an army without paying for it．

Taxes, therefore, cannot be avoided．We buy our own food and clothes and pay for our own amusements, but there are several things that the State finds the money for, and that are necessary for us if our society is to continue．So we have no real cause to complain when we are asked to supply money to be spent for the good of ourselves and for our fellow-citizens．

1.Indirect tax means _______．

A．tax that one pays direct to the government

B．tax that is not paid directly to the government

C．tax that is paid as an extra amount added to the price of certain goods

D．Both B and C

2.Which of the following is right?

A．Taxes are paid to the sellers．

B．Income-tax is an indirect tax．

C．The tax on new clothes is paid in money direct to the government．

D．Tax is amount of money that you have to pay to the government so that it can pay for public services．

3.People have no real reason to complain about having to pay taxes because _______．

A．some shopkeepers are very rich

B．they need money to buy goods from abroad

C．their children need education

D．the money is spent on the things that they and their families need

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.

Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland（瑞士）and China, built by the government（政府）to help some of the people live during a great war.

But will people change if they live under the ground for a long time？For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals（化学制剂）in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone？

1.People will live under the ground because _________．
