A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers.

    Q: Why is the sky blue?

    A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits “raised area” in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules (分子) because it has a shorter wavelength , which in turn scatters (使分散) it in different directions. That’s why when you look up at the sky, it appears to be blue.

    Q:Why does the moon sometimes appear during the daytime?

    A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit (轨道) around the earth is when it is right between the earth and the sun. That’s because its back , which is not lit by the sun, is facing us.

    Q: Where do birds/ honeybees go in winter?

    A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50°F. Instead ,they get together in the lower central area of the hive （蜂巢）and form a ball around their queen. This helps keep both warm enough to survive the cold winter months.

1.The sky looks blue mainly because the color blue in the sunlight_______.

A. has the longest wavelength among all the colors

B. cannot be taken in by the gas molecules

C. doesn’t hit “raised area” in the atmosphere

D. cannot pass through space successfully

2.How long can’t the moon be seen during the daytime in a month?

A. 2                             B. 28                           C.30                                      D. 31

3.What do honeybees choose to do when the temperature drops below 50°F?

A. They choose to be active in the wild.

B. They choose to keep themselves warm.

C. They choose to travel to a warm place.

D. They choose to get together in the upper central area of the hive.

4.What is NOT explained in the passage?

A. Why is the sky blue?

B. Why is the moon able to be seen during the daytime?

C. Why do birds travel in winter?

D. Where do honeybees go in winter?

Ever thought of moving to a new country? How about starting a new country? Patri Friedman is planning to do just that. He left Google years ago to set up the Seasteading Institute. And his dream is to build seasteads-----floating micro-nations in the middle of the ocean.

So, what will life on a seastead be like? Probably a bit like life on a cruise liner (游轮), but much larger, with shops, gyms, swimming pools, schools and other areas. In fact, the early seasteads may actually be specially-rebuilt cruise liners. But as science advances, Friedman believes they’ll become more like floating cities, with several hundred people.

Seasteading raises a lot of questions. First of all, how will the new countries make money? The Seasteading Institute has suggested several money-making ideas, including ocean-based theme parks, casinos (赌场) and fish farming. There’s also the questions of safety. With storms, typhoons and pirates (海盗) , the high seas are a dangerous place. However, the Institute says that it can stand bad weather and prevent crimes with its well-designed systems.

So, is this just a day dream? Well, maybe not. One of the people behind the project is Peter Thiel. He founded PayPal and was one of the first investors (投资者) in Facebook. So far, he’s donated $ 500,000 to the project.

And Friedman isn’t wasting any time. He recently announced the creation of the Poseidon Award. This will be given to the first seastead with fifty people. Friedman is hoping to hand out the award in 2015.

1.Where did Friedman use to work?

   A. In Facebook.          B. In Seastead Institute .   C. In PayPal.         D. In Google.

2.A future seastead may be most likely to look like ___________________.

   A. a cruise liner          B. a floating city         C. a theme park       D. a fishing farm

3.What can we infer from the passage?

   A. Friedman is planning to move to a new country.   

B. Friedman is worried about the safety of seasteads.

   C. Friedman has got some supporters for his project.  

D. Friedman has already won the Poseidon Award.

4.Which of the following can be the best titles of this passage?

   A. Seasteading: a new idea of living               

B. Seasteading: a wild way of farming

   C. Peter Thiel: a man behind the project            

D. Patri Friedman: a crazy day dreamer

       A doctor said in his study that four “people” live in a person's mind (意识、内心).They are father, mother, adult, and child.The father is like a teacher __1__ asks himself and others a lot.The mother is so __2__ that she always cares about other people.The adult is a smart worker but likes to correct others' mistakes.And the child is cute but may not __3__ others.

   If the four “people” in a person's mind __4__, the person can become a happy and healthy man.He __5__ his life and people like to be with him.However, not everyone is like this, because people come from __6__ families.If a person's parents ask him __7__, he will not show his real feeling easily.He asks too much of himself, too.That is, among the four people in his mind, the “father” and the “adult” are stronger than the “mother” and the “child”.__8__ if a person's parents are too kind to ask him anything, he will care about himself only.In his mind, the “__9__” is stronger than the other three “people”.How to __10__ the four “people” in the mind is very important in having a happy life.So we need to learn to develop a happy and healthy mind.
