【題目】

The world’s largest radio telescope was finished on Sept. 25, 2017 in China.

FAST is a five-hundred-meter telescope. It is also called Tian-yan ("The Eye of Heaven"), with a dish the sire of 30 football grounds, deep in the mountains of southwest China's Guizhou Province. The giant dish is built on a howl-like valley.

The surrounding area has "radio silence" as there are no towns and cities within a 5-kilometer radius(半徑范圍) and only one county center within 25 kilometers.

FAST is made up of 4,450 panels(面板). The second largest radio telescope is in Russia. The bigger dish will be able to pick up weaker signals (信號).

The radio telescope is like an ear, listening to tell meaningful radio messages from white noise in the universe. With the help of the telescope, we can receive weaker and more radio messages far away in space. It will help us to search for intelligent life outside of the Galaxy(銀河系) and explore the origins(起源)of the universe. "Any of its discoveries will lead to a Nobel Prize," said Joseph Taylor, a Noble Prize winner.

The FAST project began in 2011. And the telescope is expected to remain the global leader for the next 10 to 20 years.

1Where was FAST developed?

A. In China.B. In Russia.C. In America.

2The underlined word "giant" probably means "___________" in Chinese.

A. 神秘的B. 巨大的C. 寬廣的

3FAST is used to __________________.

A. explore the origins of human beings

B. receive distant radio messages from the universe

C. watch the beautiful scenery of the Galaxy

4From the passage, we can know that __________________.

A. FAST is the largest radio telescope all over the world so far

B. Noisy towns are around the telescope within a 5-kilometer radius

C. The second-largest radio telescope is made up of 4,450 panels

5How long did it take to finish the FAST project?

A. About twenty years.B. About ten years.C. About six years.

【題目】

The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without falling down?

There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards the earth. The other force is created by the rotation (旋轉(zhuǎn)) of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth (the force which pulls everything towards the ground) is like a rope which keeps the satellite from flying away.

Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (墜落) down to the earth.

1Which of the following uses of satellites is NOT mentioned?

A. communication

B. monitoring the weather condition

C. doing some research

D. taking pictures

2The force that pulls the satellite towards the earth is created by ________.

A. the earth

B. the satellite itself

C. the rotation of the satellite

D. the rope

3Why can’t the satellites fly away?

A. Because of the force from the earth.

B. Because the satellite is too big.

C. Because of the force created by the rotation of the satellite around the earth.

D. Because people on earth have made ropes to tie the satellites tightly.

4The satellite will finally crashes down to the earth ________.

A. when it flies faster

B. when its speed slows down

C. when people cut the rope

D. when there is no electricity in it

5Which of the following is TRUE according to the passage?

A. There are four forces acting on the satellite.

B. The force of gravitation makes the satellite go round and round.

C. As time goes by, the satellite will finally fall down.

D. The satellite will stay in space forever.

【題目】 語篇翻譯 閱讀下面的短文,將劃線部分譯成英文或中文。

It’s difficult when a good friend isn’t around--maybe because you have moved to a different school or a different class or you are ill at home. You may feel unhappy without friends. 你想交新朋友嗎?But do you know how? How do you start? How do you get along with people? Here are four suggestions for you.

Greet people. Greet people and hope they have a good day--whatever time of a day it is. It never hurts anyone. It also makes people think that you are outgoing and friendly.

Smile. 讓別人喜歡你的最簡單的方法就是微笑。There’s a great reason why it takes fewer muscles to smile than to cry. Nature just wishes us to smile more.

Help people. Simple actions, like helping people carry something or open a door, show your kindness. Just as the saying goes, “ A true friend reaches for your hand and touches your heart.”

Respect ( 尊 重 ) others. Everyone is different from each other. The world is full of differences. So learn to respect others. It’s the only way that other people will respect you.
