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.

We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It’s called wireless charging and this trend is just starting.

Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they’re placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won’t need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.

Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.

1.What is a problem with many modern appliances?

A. Most people can’t afford to pay for them.

B. They can cause a lot of junk around the house.

C. They go out of style too quickly.

D. They are not very entertaining.

2.Why is wireless charging beneficial for medical patients?

A. It often brings down the cost for their medical bills.

B. Wireless charging has shown to cure people of serious diseases.

C. It is more convenient to check or repair their devices.

D. It’s being used as a replacement for many pills.

3.Which of the following is a disadvantage of wireless charging?

A. Wireless charging means devices take up more space.

B. People can now buy fewer devices for their homes.

C. It takes longer to charge your battery wirelessly.

D. People can’t plug in their devices conveniently.

4.What seem to be the author’s attitude towards wireless charging?

A. Cautious. B. Uncaring.

C. Disapproving. D. Favorable.

We are now living in an information world that TV, cell phones and the Web are wide used. It seems that many people can not enjoy them without them.

Our first winter in Canada was the happiest we have ever experienced. We were living in the countryside then and had just arrived from Hong Kong that autumn.

One evening in mid December snow began to fall. When we looked out of the window and saw that it was snowing, we all cheered. It was the first snow we had ever seen and we were excited. We could hardly wait for the snow to stop so that we could go out to play. Next morning when we woke up, it was still snowing. We switched on the radio and learned that more than ten inches of snow had fallen during the night and that since the roads were blocked（堵塞） there would be no school that day. We jumped up and down for joy and begged mother to let us go outside to play in the snow. She said we could go out after breakfast if we dressed ourselves warmly and promised to come back as soon as we felt cold.

When we went out, the snow had almost stopped. The roads, paths, gardens, and playing grounds were all hidden under a white blanket of soft snow. It was the most beautiful sight we had ever seen. Just then, we saw some neighbors’ children coming out to play. We ran over to join them. Together we built a snowman and a snow house. 　　　　　　 After that, we took turns sliding down a hill on a large piece of card-board. We were having so much fun when supper time came. Mother almost had to force us to go in and eat.
