Many animals have tails答案解析

Have you ever heard that we humans use only ten percent of our brains? This opinion holds a certain appeal because if it were true, then we could instantly become ten times more intelligent just by firing up that sleepy majority of the brain!

The idea that we use only a small part of the brain dates back to animal experiments in the 19th century. When scientists stimulated (刺激) a specific part of the brain, the animal moved its leg or tail. If a tiny part of the brain could do something so great, what was the use of the rest of the brain? Some scientists assumed that large parts of the brain were simply useless.

Then, in the early 20th century, scientists observed that stimulating certain parts of the brain had no physical effects. They named these seemingly useless parts of the brain the “silent cortex.” Today we know that in humans, much of the “silent cortex” is actually devoted to complex activities like language, learning, and imagining.

Brain scans have shown that different parts of the brain become much more active as we shift (切换) our attention and focus, but even as we sleep, many areas of the brain are extremely active. Would you be smarter if your entire brain constantly worked to maximum capacity (能力)? Interestingly enough, the opposite is probably true. The less brain activity you need to perform a given task, the more the brain as a whole is able to do.

1.Why does the opinion mentioned in paragraph l seem appealing?

A. People wish to become much smarter.

B. People believe it is scientific.

C. People know nothing about the brain.

D. People want to make little use of their brain.

2.What did scientists discover in their experiment in the 20th century?

A. The majority of the brain is sleeping.

B. Animals’ legs and tails have some connection with their brain.

C. Stimulation on some parts of the brain causes no physical reaction.

D. Certain parts of the brain are devoted to language and learning activities.

3.“Silent cortex” has proved to be______.

A. sensitive to stimulation

B. useful in complex activities

C. responsible for physical reaction

D. more active than the other parts of the brain

4.If you need less brain activity to perform a task, _______.

A. you will feel sleepy

B. you must shift your focus

C. you can use your brain to the fullest

D. you will be more productive

      There is little rain in deserts. Because deserts are so dry,they have no “ quilt ” to help stop the soil from going away.As a result,they may get very hot during the day with the sun shining,but don't hold the heat overnight. Many deserts can quickly get cold once the sun goes down. Some deserts can reach temperatures of over 100 degrees F during the day and then drop below freezing (32 degrees F) during the night.

It covers over 3 million square miles of Africa.Other large deserts include the Arabian Desert in the Middle East,the Gobi Desert in Northern China and Mongolia,and the Kalahari Desert in Africa.

      Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat.Other animals keep water that they can use later.The camel stores up fat in its hump while other animals keep something they need in their tails.

      Only certain types of plants can live in the terrible environment of the desert.You wonH see a lot of tall trees in the desert.Most plants have a way to keep water in their leaves,or trunks so they can live a long time without water.

      Now deserts cover around 20% of the world’s land,but they are growing.This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it?

31. How is the weather during the night in the desert?

   A. Hot. B. Cold. C. Cool.

32. Where does the camel store up fat?

   A. In its hump.

   B. In its stomach.

   C. In its tail.

33. Why won’t we see a lot of tall trees in the desert?

   A. Because of few people there.

   B. Because of the sun shining.

   C. Because of the terrible environment.

34. How much of the land do deserts cover in the world?

   A. One fifth.

   B. Less than 10%.

Bears are found in Asia, Africa and America. They are very strong, with short tails and thick legs. Bears eat almost everything. They seem to enjoy meat, vegetables, fruit, milk and rice.

Bears are not quite dangerous as people imagine them to be. Like most animals, they will try to stay away from human beings. However, bears are not weak animals. Sometimes they kill hunters, for they can be very dangerous.

Bears have a good sense of smell but they have poor eyesight. They are also hard of hearing but they are very clever. They feed mainly on roots, frogs, fish and also small insects. They will sometimes kill deer and other large animals, but they seem to like small animals better.

In the cold area, bears hibernate, or go to sleep from October to April. Before they start to hibernate, they eat a lot and store fat. The mother bear has its babies, usually two, towards the end of hibernation. A large bear is much cleverer than a cat and most other animals. You may notice at the zoo how cleverly they ask for food. They sit up and hold out their paws. You would have to teach a dog such a trick but the bears learn this by themselves.

Dolphins are our friends. They can use tools to solve problems although they don't have hands.   For example, scientists have ever found that a dolphin can make a shy eel(鳗鱼) come out of its hole with a dead fish.
Dolphins use different sounds to exchange information with each other. Scientists in Hawaii have developed a sign language to give instructions to dolphins, and the results are amazing. They find that dolphins not only understand the meaning of individual (个别的) words, but also understand the importance of word order in a sentence.
Most animals enjoy playing — but dolphins seem to like making their games as challenging as possible. On a beautiful day in 1997, scientists at a beach watched a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins came up to the dog and then started throwing it into the air. The dog seemed to enjoy the "game" and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours, but they are very good at our "IQ tests” . For example, they will jump out of the water when they hear a whistle (口哨) noise. They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers, but it is certain that watching a dolphin show is fun.

Man is the most intelligent animal created by God because God has given him language which other animals do not have. Communication makes life extremely convenient and easy. Language plays a very important role in life as any emotion can be easily and effectively conveyed (传递) through language to anyone. But all this is applicable and beneficial only to human beings. What about animals? How do they communicate with each other?

We all know that animals do not have the ability to use language as a medium for communication. But they do have other means of conveying messages to other animals, of which use of body language is the most important one. The messages can be of many types like conveying food location, danger alarms, appreciation of good deeds like helping other animals in dangerous situations, etc. There are two main types of communication in animals: verbal (语言的) communication and non-verbal communication.

Sound is one of the most common types of verbal communication in animals, and majority of the species use it as the medium to convey messages. Bats have to rely on sound waves to communicate. They mostly rest in the morning and become active at night to search for food and do other tasks. All the birds communicate through their chirping. Mammals generally make use of sounds to give calls to other members of their community. Whales are the perfect examples, which use sound waves for communication. They have a whale song, which they repeat after regular intervals.

Facial Expressions

This kind of communication is mostly found in dogs. When they are angry, they show their teeth and raise their ears. On the other hand, when they are frightened, they pull their ears behind and open their mouth. Also, in birds, when the parent bird brings food for the offspring, the begging expression can be observed on the offspring’s face.

Gestures and Body Movements

This type of communication is common not only in animals, but in human beings too. All human beings, although they use language for communication, tend to use gestures and body movements as well while communicating. Honey bees are the most enthusiastic creatures on earth because they dance to communicate. Some bees dance in the hive (蜂箱) so that other bees get signals of the location of the honey comb. A deer waves its tail to warn others of coming danger.

51. What does this passage mainly talk about?

A. What messages animals can convey.

B. Why life is easier for human beings.

C. Why man is the most intelligent animal.

D. How animals communicate with each other.

52. Our life is more convenient and easier owing to the fact that ______.

A. other animals do not have any emotion

B. we can communicate with each other through language

C. we also use body movements while communicating

D. other animals use sounds to give calls to their members

53. What’s the most important way for animals to convey messages?

A. Use of body language.

B. Use of sounds.

C. Use of facial expressions.

D. Use of dancing.

54. When a dog pulls its ears behind with the mouth open, we can tell it ______.

A. is angry

B. is frightened

C. has been begging for food

D. has eaten too much

55. Which of the following doesn’t belong to non-verbal communication?

A. The begging expression.

B. Relying on sound waves.

C. Dancing.

D. Waving tails.

It’s known that the marmots(土拨鼠) are very shy around humans, beating their tails and making loud noise with their teeth to tell other members of their colony to run away.

But when these marmots see Matteo Walch, they run to his side and show him nothing but affection(喜爱).

The eight-year-old Matteo Walch built up a great relationship with the creatures since first being taken to see them by his nature-loving family four years ago.

The family return to visit these marmots in Groslocker in the Austrian Alps(阿尔卑斯山) for two weeks every year.

Matteo loves those animals and they are not at all afraid of Matteo because he has a feeling towards them and they understand that.

Marmots stand at around 18cm tall and can reach up to 50cm in length. Strangely, the animals are heavier in autumn, when they can weigh up to 8kg, but 3kg in the spring months.

Michael, a teacher from Innsbruck, Austria, has taken lots of photos of Matteo and his marmot friends during the past four years.

He said,“I could spend several hours watching animals. It’s great that I have been able to document the marmot’s natural behavior around Matteo without making them afraid of me and my camera, I wanted to capture(用影片文字等记录…的原样) the animals exactly the way I see them ---the way they behave among each other.”
