When it comes to intelligence, human beings are the top dogs of the animal kingdom. But in recent years, scientists have been documenting surprising intelligence and emotional depth in animals ranging from honeybees to elephants. Here are some amazing examples.
Artistic Monkey Business
Jannet Schmid, director of the Little River Zoo in Norman, Oklahoma, learned a lot about the intelligence of capuchin monkeys. She and her busband adopted a young male, named Bailey. The capuchin particularly liked taking car rides, insisting that he insert the key and ride in the front passenger’s seat.
Now Bailey has become a devoted painter. He uses brushes to create colorful, abstract paintings, and prefers not to be disturbed.
Prairie Dog Sound
Through a variety of birdlike sounds, prairie dogs warn each other of approaching creatures. They demonstrated a surprisingly complex communication system. In his 25 years of study, Slobodchikoff, a professor of biology, has recorded them pronouncing ten nouns including hawk, deer and coyote, a number of adjectives to identify color, size and shape, and even some verbs to indicate speed.
In an ongoing study, Slobodchikoff learns that their brain contains a very extensive vocabulary. He once used his best prairie dog sound to say coyote, and they just looked at him in anger as if he had said a bad word.
Ivy League Parrot
One African grey parrot Alex is said to have the cognitive abilities of a five-year-old child. Alex can identify 50 different objects, seven colors, five shapes, quantities up to six, and the concepts of bigger, smaller, same and different.
Also Alex is considered to make reasoned decisions. During an experiment, researchers gave Alex different-colored blocks in sets of two, three and six. When asked which color group had five blocks, Alex replied, “None.” And he answered the same in repeated tests. Obviously, he interpreted the concept of “none” as an absence of quantity all on his own. That’s a lot like a high school student answering questions on a quiz show.
56.Which of the following is true?
A. Bailey is as clever as a child of five.
B. The prairie dog loves taking car rides.
C. The capuchin monkey is fond of painting.
D. Alex develops a communication system.
57.The underlined word “coyote” in Paragraph 4 refers to ________.
A. a verb                     B. an animal              C. a warning                       D. an adjective
58.The African grey parrot Alex can ________.
A. answer questions on a quiz show
B. understand the figure “7”
C. identify five colors and seven shapes
D. apply the concept of “none” correctly
59.What is the passage mainly about?
A. Animal communication                           B. Animal research
C. Animal intelligence                                  D. Animal information

Frankly, I very much appreciate myself. Yes, I admit I’m in many respects not as good as other people, but I don’t think I’m always not good. When I find what I’ve done or written is okay, I’ll remain pleased with myself for quite a few days, and in case I receive praise for it, I’ll even become so excited as to add a few words to glorify myself.

True, I’m not modest at all. People may call me conceited (自负的). But I think otherwise.

I also appreciate other people. I appreciate anything good. Isn’t it unfair to forget appreciating myself while appreciating others?

We Chinese generally tend to be modest, and we take pride in being so. For example, a Chinese will call his own wife zhuojing, meaning “my humble wife”, and his own writings zhuozuo, meaning “my poor writings”. But if you should call his wife a “rustic (乡巴佬的) woman” or his writings “trash”, he would, I’m sure, slap the table in a rage and declare he would make a clean break with you. As a matter of fact, there is probably no difference at all between what is said by him and you respectively.

I don’t think it’s wrong for you to freely praise yourself if you’re really worthy of praise. As we know, there is an old Chinese saying disparaging (蔑视的) a melon peddler(商贩), named Lao Wang, who keeps praising his own goods. Well, why can’t he praise his melons if they are really sweet and juicy?

Friends, Lao Wang sells melons for a living. How could he carry on business if he, by imitating the affectations of us intellectuals, were to show false modesty about his melons? He would sure enough die of starvation.

Self-appreciation is therefore key to professional dedication (贡献) and enjoyment of work. One will lose confidence in continuing with writing when he pauses to admire his own essays.

Needless to say, the same is true of those who make a living with their pen.

49. The best title for the passage would be __________.

A. On Self-Appreciation                        B. Types of Appreciation

C. Power of Appreciation                     D. Uses of Appreciation

50. The underlined word “zhuojing” in Paragraph 4 means _________.

A. wife high in position                            B. wife low in position

C. wise wife                                           D. foolish wife

51. The writer points out with an example about an old Chinese saying that _________.

A. self-appreciation is also an active way of attitude to life and work

B. a false modesty will lose confidence in continuing with writing

C. one person pauses to admire his own essays without self-appreciation

D. one doesn’t praise his melons if his melons are really sweet and juicy

52. Which of the following is TRUE according to the passage?

A. If I find what I’ve done or written is wrong, I’ll appreciate myself.

B. I never appreciate other people because I think others are foolish.

C. If you think poorly of your friend’s writings, perhaps he’ll be angry at you.

D. Lao Wang will die of starvation because he never praises his melons.
