Here is an astonishing and signficant fact:Mental work alone can’t make us tired. It sounds absurd. But a few years ago, scientists tried to find out how long the human could labor without reaching a stage of fatigue(疲勞). To the amazement of these scientists, they discovered thett blood passing through the brain, when it is active, shows no fatigue at all! If we took a drop of blood from a day labourer, we could find it full of fatigue toxins(毒素) and fatigue products. But if we took blood from the brain of Albert Einstein, it would show no fatigue toxing at the end of the day.
So far as the brain is concerned, it can work as well and swiftly at the end of eight or even twelve hours f efforts as at the beginning. The brain is totally tireless. So what makes us tired.
Some scientists declare that most of our fatigue come from our mental and emotional(情感的) attitudes. One of England’s most outstanding scientists. J. A. Hadfield,says,“The greater part of the fatigue from which we suffer is of mental origin. In fact,fatigue of purely physical origin is rare.” Dr. Brill, a famous American scientist, goes even further. He declares,“One hundred percent of the fatigue of a sitting worker in good health is due to emotional problems.”
What kinds of emotions make sitting workers tired?Joy?Satifaction?No!A feeling of being bored,anger,anxiety,tenseness,worry,a feeling of nt being appreciated---those are emotions that tire sitting workers.Hard work by itself seldom causes fatigue.We get tired because our emotions produce nervousness in the body.

Toucans(巨嘴鳥), a kind of tropical birds known for its colorful beak, are very smart. In Mexico, my dad became friends with a toucan that was in a “walk in and see the birds” cage. The toucan was so smart that it knew how to get out. It just needed some human to help it. It almost flew out while we were leaving!
I also noticed that all toucans have different beaks! They also have very long unique beaks with an extremely long tongue. It struts(大搖大擺地走) around with its chest sticking out and beak pointed forward. The toucan is a beautiful bird! The beak has a red tip (different shades on every one), but sometimes there is a little turquoise on the bottom half. Then, right where the beak separates there is a splotch of yellow. And the rest of the beak is green. The toucan takes very much pride of itself.
The toucan eats fruit and seeds. The ramphastidae(the toucan family) is known for its long beak, and 37 species. Toucans also feed on insects, small lizards, bird nestlings and eggs. They nest in hollow trees where they incubate and care for their young.They are found in the woody areas.
Of the various toucan facts, here is an odd one. Citizens of Central and South America associate the toucans with evil spirits. They think the birds can be the personification of evils. Where couvades(父代母育) is practiced, the father of a new child must not eat toucan flesh as it is believed to bewitch the new-born child. Yet the toucan can also be a tribal totem(圖騰). So the medicine men use it as a symbol to fly to the spirit world.
60. Which of the following words is NOT suitable to describe toucans?
A. Intelligent B. Confident C. Dangerous D. Colorful
61. The second paragraph mainly talks about _______.
A. where toucans strut around B. how toucans get food
C. what toucans look like D. when toucans lay eggs
62. What does the underlined word“incubate”probably mean in paragraph 3?
A.Hatch eggs B.Take cover C.Gather strength D.Keep warm
63. We can learn from the last paragraph that _______.
A. all citizens of Central and South America are afraid of toucans
B. the toucans can also be used as medicine to cure diseases
C. a new child must not eat toucan flesh because it is poisonous
D. some people believe toucans can bring them misfortune

Talking on a mobile phone is expensive, so a lot of people send text messages. Text messages are much cheaper than talking on a mobile phone, and you can make it even cheaper by shortening the words that you use. You can do this by taking out “unimportant” letters in the words and using numbers instead of words(2=to, 3=free, 4=for, 8=ate, h8=hate, etc. ). Here is an example :Im 3 nw, why nt gv me a cll? (I’m free now, why not give me a call?)

There are many American expressions about insects--- like bees, for example. Bees are known as very hard workers. They appear to be busy, moving around their homes, or hives (蜂窩). So you might say you were as busy as a bee if you spent your weekend cleaning your house. In fact, you might say your house was a beehive of activity if your whole family was helping you clean. You also might say you made a beeline for something if you went there right away. When we go to see a movie, my friend always makes a beeline for the place where they sell popcorn (爆米花) .
Here is an expression about bees that is not used much any more, but we like it anyway. We think it was first used in the 1920s. If something was the best of its kind, you might say it was the bee’s knees. Now, we admit that we do not know how this expression developed. In fact, we do not even know if bees have knees!
If your friend cannot stop talking about something because she thinks it is important, you might say she has a bee in her bonnet (女帽). If someone asks you a personal question, you might say “that is none of your beeswax”. This means none of your business.
Speaking of personal questions, there is an expression when their children ask, “Where do babies come from?” Parents who discuss sex and reproduction (生殖) say this is talking about the birds and bees.
Butterflies are beautiful insects, but you would not want to have butterflies in your stomach. That means to be nervous about having to do something, like speaking in front of a crowd. You would also not want to have ants in your trousers. That is, to be unable to sit still.
1. If you make a beeline for something, you ______ .
A. are as busy as a bee B. go quickly and directly towards it
C. always go to the same place D. buy something at a certain place
2.The underlined expression “ it is the bee’s knees” _______ .
A. is not used at all now B. was first used in the 1820s
C. reminds us that bees have knees D. means “it is very good”
3. If you ask your American friend Jack “How old is your wife?” he may say “______.”
A. It is none of your beeswax B. You have a bee in your bonnet
C. It is the bee’s knees D. You are talking about the birds and bees
4. When you have butterflies in your stomach, you ______ .
A. are too sick to sit still B. have ants in your trousers
C. are nervous about something D. have a stomachache
5.The passage mainly tells us _______.
A. some interesting and useful insects B. some expressions about insects
