    The _ 31_ teacher, Mr. Litmus, had asked his students to study some special animal. They would write a short report, and tell the rest of the class their conclusions(结论). Some talked about dogs, others about horses, and some chose fish. But the most interesting _32_ of all was made by little Sophie.

    “I found that _33_ are terribly ill- tempered(脾气坏的),” she said, very sure of herself.

    Everyone smiled, waiting for her to _34_. Then Sophie explained, “I spent hours in my house, watching flies. When they flied _35_, everything was OK, but when they found a _36_ they would really be noisy. I had always thought they made that _37_ with their wings, but they don’t. With my daddy’s telescope I watched the flies really closely, and saw that what they were really _38_ was shouting and protesting. They were so hysterical (歇斯底里的) that they couldn’t fly out of the window, and they would just _39_ their heads against the glass again and again. If only they had _40_ the butterfly that passed by, they would have seen that the top of the window was _41_. The butterfly tried to tell them, but it had no _42_ at all. The flies just kept on shouting and complaining.”

    Mr. Litmus was _43_, and explained to the class that that form of fly’s behavior had nothing to do with _44_. Instead, it was an example of animals having different _45_ of intelligence .

    And this was what _46_ a big disorder in the science class. Many parents had to come and complain because their children had _47_ their parents among the least intelligent of creatures! This, said the children, was because the parents did nothing but complain, and they _48_ listened to anyone.

    Mr. Litmus had to do a lot of explaining, and quite a few parents _49_. It helped some of them realized that, although they weren’t _50_, they often behaved not terribly intelligently.

I was truly afraid of the dark and of getting lost when I was a child. These fears were very real and often caused me some uncomfortable moments.

Perhaps it was the strange _36_ things looked and sounded in my familiar room at night that _37_ me so much. There was never complete _38_, but a streetlight or passing car lights _39_ clothes hung over a chair take on the _40_ of a wild animal. Out of the corner of my _41_, I saw the curtains seem to move when there was no _42_. A tiny sound in the floor would seem a hundred times louder than in the daylight. My _43_ would run wild, and my heart would beat fast. I would _44_ very still so that the “enemy” would not discover me.

Another of my childhood fears was that I would get lost, _45_ on the way home from school. Every morning I got on the school bus right near my home. That was no 46_. After school, _47_, when all the buses were _48_ up along the street, I was afraid that I’d get in the wrong one and be taken to some _49_ neighborhood. On school or family trips to a park or a museum, I wouldn’t _50_ the leaders out of my sight.

Perhaps one of the worst fears _51_ all I had as a child was that of not being liked or _52_ by others. Being popular was so important to me _53_, and the fear of not being liked was a _54_ one.

One of the processes(过程)of growing up is being able to _55_ and overcome our

fears. Understanding the things that frightened us as children help us achieve greater success later in life.

  A wind tunnel is a device used for testing airplanes or plane models.

  In a wind tunnel air is blown over an airplane or a model placed in a test section.Wind tunnel test sections are different in size depending on airflow speed requirements.Some low-speed tunnels have test sections large enough for a complete small airplane.In the very high-speed tunnels used for space testing, however, the model may be as small as a pencil.

  There are two methods of feeding air to the test section.In the continuous flow tunnel air-flow is produced by electric fans.It is forced through the tunnel to the test section, then through another tunnel section back to the starting point for refuse.

  The other method involves storing high-pressure air in a box, sending it out by a control device to pass through the tunnel and test section into another box.This type of system is generally used for a very short period of high-speed airflow.

  Wind tunnels are usually used to test airplanes before they are flown.Problems in an airplane can be found when it meets the high-speed airflow in the tunnels.For instance, if the wings are built so that they would weaken at high speeds, this fact can be discovered in the tunnel, saving many lives and millions of dollars.

  In a wild tunnel scientists also find out how different planes will act at different speeds.They find out such things as how smoothly an airplane is flown, how slowly a plane can fly before it starts to drop, and how fast it can climb.

(1)

Some wind tunnel sections are larger than others because ________.

[  ]

A.

they are used for larger planes

B.

stronger wind can be produced in them

C.

they are built to meet higher requirements

D.

the wind used in them flows at a lower speed

(2)

What does the underlined part “this fact” refer to?

[  ]

A.

The wings are not good enough.

B.

It costs a lot to test a plane.

C.

Some problems are found about the plane.

D.

Many people will die in a plane accident.

(3)

A wind tunnel can be used to find out ________.

[  ]

A.

how fast a plane can rise

B.

how smooth a plane’s surfaces are

C.

if a plane can land in windy and rainy weather

D.

if a plane will drop when flying at a low height

(4)

The writer wrote the passage mainly to explain ________.

[  ]

A.

how a plane is built

B.

how a plane can be tested

C.

the relation between the wind and speed

D.

it is difficult to test a plane
