Question

【题目】The moon is providing a rare triple treat this week. On Wednesday, much of the world will get to see not only a blue moon and a “supermoon”, but also a total lunar eclipse(月蚀). Having all three events taking place at the same time is extremely unusual.

A total lunar eclipse happens when the Earth comes between the Sun and a full moon. The Earth blocks the sun’s light, making the moon appear dark in the sky. A blue moon is a second full moon in one month. It is rare enough that English speakers use the expression “once in a blue moon”to describe it! A supermoon is a full or new moon. It appears brighter and bigger than usual because the moon is closer to the earth than usual.

In a total lunar eclipse, the Earth covers the moon’s surface with its shadow, giving it a red-like color. For that reason, it is also known as a “blood moon. ”Some people are calling this week’s lunar event a “super blue blood moon.” Noah Petro is a scientist with the American space agency NASA. He is calling the lunar event, “the Super Bowl of moons.” No matter what the name, it is likely to impress if the skies are clear.

Just as last August’s total solar eclipse cooled the Earth’s surface, a lunar eclipse cools the surface of the moon. It’s this sudden cooling- from the heat of direct sunlight to almost a deep freeze—that researchers will be studying.

【1】Which of the following picture shows a total lunar eclipse?

A. B.

C. D.

【2】What does the underlined phrase in paragraph 2 usually refer to?

A. Something that is rarely noticed.

B. Something that is round and bright.

C. Something that does not happen often.

D. Something that can arouse people’s curiosity.

【3】What will the lunar eclipse do to the moon?

A. Make it absorb less heat.

B. Make it give off less heat.

C. Make its inner part cooler.

D. Make its surface heat go down.

【4】What’s the main idea of the passage?

A. It explains how the lunar eclipse happens.

B. It tells us NASA’s achievements in observing the moon.

C. It offers us some information about a rare total lunar eclipse.

D. It is about the effects that the lunar eclipse will have on the moon.

Answer 1

【答案】

【1】A

【2】C

【3】D

【4】C

【解析】问斩主要介绍了月全食的相关知识。

【1】细节理解题。根据文章第二段A total lunar eclipse happens when the Earth comes between the Sun and a full moon. The Earth blocks the sun’s light, making the moon appear dark in the sky.可知月全食是地球在太阳和月亮之间，地球把太阳的光遮住，使得月球一片漆黑，所以A符合。

【2】词义猜测题。根据文章第二段It is rare enough that English speakers use the expression “once in a blue moon”to describe it!可知once in a blue moon 是指这种现象很罕见。

【3】细节理解题。根据文章最后一段Just as last August’s total solar eclipse cooled the Earth’s surface, a lunar eclipse cools the surface of the moon.可知月全食对月球的影响是是月球表面的温度急剧下降。

【4】主旨大意题。通读整片文章可知，文章主要介绍了月全食的相关信息，所以C正确。
