Cosmetics have been used throughout history. The ancient Greeks, the Egyptians, and the Romans all used various kinds of makeup. Some of these cosmetics were used to improve their appearance. Others were used to protect their skin. But in some cases, things used for makeup were dangerous, or even deadly! Some of the first skin care treatments started in Egypt. In fact, Cleopatra was known to use them. She thought a bath in milk and honey left her skin silky smooth. Egyptians also developed some of the earliest sunscreens. They used oils and creams for protection against the sun and dry winds. Egyptian and other ancient cultures also used various powders on their skin for beauty. Egyptians used black kohl around their eyes. Romans put white chalk on their faces. And Indians painted red henna on their bodies. Most of the ancient cosmetic powders, oils, and creams were harmless. But in the name of beauty, some people applied dangerous chemicals and poisons to their skin. During the Italian Renaissance, women wore white powder made of lead on their faces. Of course, doctors now know lead is like a poison for our bodies. Also around the time of the Renaissance, women in Italy put drops of belladonna in their eyes. Belladonna is a very poisonous plant. The poison in the plant affects the nerves in the body. By putting belladonna drops in her eyes, a woman’s pupils would become very large. People thought this made her more beautiful. Actually, this is why the plant is called belladonna. In Italian, belladonna means " beautiful woman. " When Elizabeth I was queen of England in the late 1500s, some rather dangerous cosmetics were also used by women there. Women were using rouge made with mercury. They were also using special hair dye made with lead and sulphur. The dye was designed to give people red hair, the same color as the queen’s hair. Over time, the dye made people’s hair fall out. Finally, women using this dye ended up bald, like the queen, and had to wear wigs. Summary: Although people have used cosmetics throughout history, not all of them have been safe. In fact, some of them have been quite (1) to people. For example, long ago in Italian (2) people thought women with big pupils were beautiful. Therefore, in the (3) of beauty, women began to put (4) of belladonna in their eyes to make their pupils larger. Today we know belladonna is poisonous, and it can affect the (5) in the body.
There are cockroaches (蟑螂) everywhere on Earth except the places that are covered with ice. Scientists have discovered about 3,500 different species of cockroaches. There is just one human species! Cockroaches can be anything in size from about five mm to nine cm. Although five mm is very small, nine cm is as long as a large rat. It is very difficult to catch most cockroaches. They"see" with the hairs on their bodies. These hairs can feel the smallest movement in the air, so the cockroaches know immediately something moves, and run to safety. Of all the species of cockroach, fortunately only three live among humans and are a serious problem. They are the German, the Oriental, and the American. One egg case of the German cockroach can produce as many as seven million cockroaches in 12 months! Our main problem with cockroaches is that not only do they look ugly to us, but they also carry diseases. They are particularly dangerous in hospitals as they eat all kinds of hospital waste or get it on their bodies. They can then carry this waste, which may contain dangerous bacteria, on to food which is then eaten by people in the hospital. Most of the bacteria that cause food poisoning have been found in the stomachs of cockroaches, so it is important that cockroaches should be kept out of restaurants and other places where food is prepared. Many people work and try to destroy cockroaches, but as soon as they find one way of doing it, the cockroaches "learn" how to deal with it. Electricity does not always kill them and they can avoid most poisons or"learn"how to deal with others. At one time, scientists thought that radiation would kill them. but they have been on Earth for about 300 million years, and it does not harm them as much as it does us. It seems probable that when there are no longer human beings living on the Earth, cockroaches will still be here. Paragraph 6 says that it is very difficult to ______.
