问答题X 纠错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 cockroach. 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.
Answer the following questions according to the passage.

填空题 1 Many of these customs include stories and beliefs related to creatures, real or magical, taking the teeth. In Asia, for example, birds and other animals are thought to play a role in taking these baby teeth. In the West, though, a fairy is thought to visit. In all cases, it is considered lucky for the animal or fairy to take the offered tooth.


2 Latter, the magpie will return and bring a new tooth for the child. This custom is also followed in other Asian countries. In both Japan and Vietnam, follow a similar tradition of throwing lost teeth onto the roofs of houses.
3 In Mexico and Spain, for instance, tradition says a mouse takes the tooth and leaves some money. But in Mongolia, dogs are responsible for taking children’s teeth away. Dogs are highly respected in Mongolian culture and are considered to be people’s guardian angels.
4 Accordingly, parents in Mongolia will put their child’s lost tooth in the fat of a piece of meat and feed it to a dog.
5 Many children in Western countries count on the Tooth Fairy to leave money or presents in exchange for a tooth. The exact origins of the Tooth Fairy are unknown, although the story probably began in England or Ireland centuries ago. According to this tradition, a child puts a lost tooth under his or her pillow before going to bed. In the small hours while the child is sleeping, the Tooth Fairy takes the tooth and leaves something else under the pillow. What she does with the teeth is a mystery. In France, the Tooth Fairy leaves a small gift or candy. In the United States, however, the Tooth Fairy usually leaves money. These days, the rate is $1 to $5 per tooth. That can add up to a lot of money from the Tooth Fairy!

判断题The secret of the successful handshake is no secret anymore. Management consultant Robert E. Brown explains what shaking hands is all about in his book The Art, the Power, the Magic: How to Read Hands that Talk.
For example, to do the "All-American Handshake", you have to look into another person’s eyes, grasp his or her whole hand, and pump it two or three times. According to Brown, this is the hand-shake of a good listener and trustworthy person.


Politicians and salespeople often use the "Two-Handed Shake" because it’s extra-friendly. Two-handed shakers put their left hand on the other person’s arm or shoulder as they shake hands. This can feel too friendly to some people, so it’s best to use it with good friends.


Watch out for people with handshakes that pull your fingers, or twist and crush your hand. If you get one of these handshakes, the person is trying to intimidate you.
Two more uncomfortable handshakes are the "Palm Pinch" and the "Dead Fish". A Palm Pincher shakes your hand with only a few fingers. In the Dead Fish shake, the person’s hand slides out of the handshake. It’s possible that the people with these handshakes are embarrassed or shy.


Shaking hands is an important part of body language. It can identify someone as truthful, friendly, powerful or nervous. It’s hard to be successful without mastering a good handshake such as the All-American. If this isn’t your natural handshake, don’t worry. Mr. Brown says that you can change your handshake with lots of practice. So, go on out there and start shaking hands. Just think of all the people you can meet.
