As they migrate, butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may use some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.

To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.

Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate(补偿, 弥补). Many migrating birds do the same thing.

The study also found that butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help farmers decide when to spray their crops.

1.What's the main idea of the text?

A.Insects migrate with the seasons.

B.The wind helps insects greatly in migrating.

C.Windsurfing insects have real direction.

D.Scientists have trouble in observing insects.

2.Scientists originally thought that _____.

A.insects always waited for their favorable winds

B.insects chose the winds they wanted to ride

C.insects were just blown about by the wind

D.insects positioned themselves in the winds

3.It is not easy to study the migrating behavior of the insects because ______.

A.the little creatures can fly very fast

B.their flight is long and high above ground

C.the wind's direction is hard to forecast

D.they have no regular migrating courses

4.According to the passage, the findings can ____

A.increase insects in number

B.instruct farmers when to spray their crops

C.prevent climate warming

D.help protect insects

Today, as with so many days, I found myself stuck in a traffic jam, and I thought I’d share my little trick for keeping calm when it seems like you are creeping along(缓慢行进).
The key to understand is that traffic jams don’t take as long as they seem to. It’s just that when we are in a hurry, and think we should be moving, but time appears to pass more than it does. To really show this, the next time you are stopped at a light that always seems to take forever to change, try to do something with your phone, your laptop, whatever you have available, and watch how much briefer the light seems.
When you enter a jam on the highway, reset your trip plan and care the time. Then, when you clear the jam, and are normally on your way again, care the distance of the jam, and the time it took to get through it. For my experience today, it took me 6 minutes to go 2 miles. Now, it happens to be mathematically convenient that your average speed on the highway is about 60 mph, or a mile per minute. So to estimate what time the jam actually cost you, just take your traffic jam passing time, and subtract(减去) the distance covered, which we know is a good estimate of the time it would have taken with no traffic jam. In my case, all that added up to 6-2="4" minutes.
Do this for every jam you are subjected to every time and watch how much less stressful they become once you understand how little time you are really losing.
【小题1】We can infer from Paragraph 1 and 2 that ________.
A. there was no traffic jam in the past
B. modern people are under great pressure
  time passes much faster during traffic jams
D. people in traffic jams are usually impatient
【小题2】What does the writer suggest when caught in traffic jams?
A. Playing a trick on other drivers.
B. Figuring out how much time the jam actually cost you.
  Doing some math problems.
D. Informing the boss about the delay.
【小题3】The underlined phrase “subjected to” in the last paragraph probably means ________.
A. experience          B. avoid                admit                     D. control
【小题4】 What’s the main idea of the passage?
A. Math is closely connected with life.
B. Stress is always a bad thing.
  Traffic jam is not as bad as you think.
D. There is no use complaining about traffic jams.

Child labor — the employment of children in industry, often against their will — has been a problem for many years. Over a hundred years ago, Charles Dickens shocked many of his readers when he described the conditions under which young children worked in British factories. The conditions Dickens described continue almost unchanged today in many parts of the world. The only difference is that today employment of children is confined(limited)to small industries and family businesses, such as hotels, restaurants and particularly farms, rather than to large factories.

Girls suffer more from child labor practices than boys. Many of them are forced to start work when they are only ten years old. Although the work they are given to do is often light, it is often harmful to the health. Recently, children as young as six years were found to be working in Asian factories, and the children were working from eight to fourteen hours a day in overcrowded and unhealthy working conditions. Sometimes a whole family group is employed, with the payment going to a parent or older relative. The children not only receive nothing or very little for their long hours of work, but also they are prevented from attending school. Therefore, when they become older they are unable to do any other kind of work.

The solution to the problem of child labor is clearly better laws to protect young children, greater supervision(监督)of industry and heavier fines for those who break the laws. Only in this way can young boys and girls be allowed to enjoy the most valuable time of their lives—childhood.

Which’s the main idea of the first paragraph?

A. Children are often willing to work in large factories.

B. Most children are working in British factories.

C. The poor working conditions of child labor in Dickens’ novel.

D. The working conditions for children are similar to those a hundred years ago.

Girls’ work is ____.

A. not harmful to the health though it is heavy

B. not harmful to the health because it is light

C. harmful to the health though it is light.

D. harmful to the health because it is heavy

Young children go to work ____.

A. because they are forced to          B. in order to be skillful in a certain kind of work

C. in order to be paid well             D. in order to earn money for education

To solve the problem of child labor, the writer suggests the following BUT ____.

A. looking over factories more closely

B. raising their payment and improving the system of education

C. improving laws of protecting children’s interests

D. punishing lawbreakers with severer fines
