Many people are interested in UFOs and there are a lot of reports about them. One report of UFOs came from a British plane on its way from New York to London in 1954.The British plane was flying over an island at 19,000 feet when the captain(机长) noticed that something was on their left and a little lower(更低) than their plane. It was about five miles away.
“It was not one object but several ones.” the captain said, “We saw one large and six smaller objects. I sent out a radio report about them and I got some information that the other planes were coming out to meet us. Before the planes arrived, the smaller objects went into the big object. The big object then became smaller and moved away fast.”
【小题1】A British plane flew to _______ in 1954.

The underlined part in the sentence “She has many good books.” is a/an________.

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?

In May, 1976, Gaynor was a nine-year-old girl and lived in North Wales. One day, on her way home from school, she saw a silver(银色的)object(物体)in a field not far from her home. The object looked like a saucer.
Gaynor was very scared. She stayed behind the tall grass and watched the door of the strange object open. She saw two aliens wearing silver suits get out. Then they used something to examine(检测)the ground. They were short and had pink eyes. After about thirty minutes, the two aliens went back into the object. Then it took off.
When Gaynor got home, she told her mother about this unusual experience, but her family decided to keep quiet about it. They didn’t want others to laugh at their daughter.
However, 18 months later, Gaynor told her story to UFO scientists. They found out that Gaynor told the truth.
