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(半径范围) 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 (信号).

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(银河系) 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.

There was a young woman. She was quite proud of growing flowers in her yard. She had been raised by her grandmother, who had taught her to love and care for flowers. So her yard was the most beautiful one in her village.

One day, while looking through a flower, list that she often ordered from, a picture of a plant immediately caught her eyes. She had never seen a flower like it before, "I have to have it," she said to herself, and she ordered it right away.

When it arrived, she found a place to plant it. She planted it at the bottom of a stone wall at the back of the yard. It grew vigorously, with very beautiful green leaves all over it. Day after day, she continued to take good care of it, and she also looked forward to enjoying the flowers, but still there were not any.

One morning, as she stood looking at the plant, she felt sad,.”It grows well, but why don’t I see any flowers?” She wanted to know the reason why her plant had not flowered, but still there was no idea.

However, at this moment, her friendly neighbor invited her to his yard and said, “Thank you so much! You can’t imagine how much I have enjoyed the flowers that you planted.” “Did I plant? Where?” the young woman was quite surprised. Quickly she walked through the gate into her neighbor’s yard. She saw that on the other side of the wall the plant was full of flowers. She couldn’t believe her eyes.

They were, indeed, the most beautiful flowers she had ever seen. The plant had grown up through the crevices in the wall.

Just because you can’t see the results of your work, it does not mean that there isn’t any fruit.

The baby is just one day old and has not left hospital yet. She is quiet but alert(警觉的). The researchers have placed a white card with two black spots on it twenty centimeters from her face. She stares at it carefully.

A researcher removes the card and replaces it by another one, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus until a third card is presented. The third card has three black spots on it. Her gaze comes back: she looks at it for twice as long as she did at the precious card. Can she tell that the number two is different from three, just 24 hours after coming into the world? Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When a little older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three beats of the drum than when they heard just two; similarly, when the researchers started beats of the drum and moved to spots.

1.What's the experiment described in Paragraph 1 mainly about?

A.The baby's sense of sight. B.The baby's sense of touch.

C.The baby's sense of smell. D.The baby's sense of hearing

A.the size of cards B.the color of pictures

C.the shape of patterns D.the number of objects

3.Why did the researchers test the babies with beats of the drum?

A.Because they wanted to keep the babies' interests.

B.Because they wanted to carry the experiment further.

C.Because they wanted to see how babies recognize sounds.

D.Because they wanted to reduce the difficulty of the experiment.

4.Where does this passage probably come from?

A.Children's literature. B.An advertisement.

C.Science fiction. D.A science report.

It's all about personal space, which means not only an imaginary space around the body, but also the space around all the senses. People feel that their space is being violated (侵犯) when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume(香水)makes you feel angry.

Whether people have had a stronger wish to protect their personal space in recent times is hard to say. Yet studies of airlines show that people have a strong desire to have space to themselves. In a survey by Trip Advisor, a travel website, people said that if they had to pay morefor some extra service, they would rather have larger seats than extra food.

Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers in front of their faces to read in fact keep a distance from strangers.

Go and watch a library table. You will notice that one of the corner seats will usually be taken first, because they are the farthest way. What if someone sits opposite to you? Maybe you will pile up books as if to make a wall..

Preference for personal space is different from culture to culture. Scientists have found that Americans generally prefer more personal space than people from other cultures. In Latin cultures, however, people are more comfortable standing close to each other.

A.Food service is better provided than seats on the plane.

C.There are not enough seats on the plane to meet people’s needs.

From the start, I sensed something special about my brother Joe. Born premature (早产), he spent his first few ______ in an incubator (恒温箱). I was four years old, having no ______ of babies. “What is that?” I said the day he ______ came home. “That’s your brother,” said my mother softly. “Call him Joe.” I touched him gently with my little hand and he grabbed hold of my finger. “Wow,” I said, “he’s strong.”

Little did I know. Joe would prove ______ than the sum of his diseases: the weakness in his legs, the limits of his mind, the never-ending night of his vision.

When he was six months old, my mother brought him home from a regular checkup from the hospital and told me to watch him while she was ______ supper in the kitchen. We started playing a game that I called “dogs” — rolling on the floor like pups (小狗). Then I looked up and saw my mother watching us. She was crying sadly. “Poor Joe, he’s ______,” she whispered, with ______ in her eyes. “The doctor told me today.”

I looked at Joe, who was laughing happily. “He can’t be blind,” I argued. “He’s truly smiling at my face.”

“Oh, no, honey. He smiles at your ______,” she replied. “He’ll never see your face.”

When he was seven, Joe spent a month in a hospital, following an operation that failed to help his legs. Walking without support seemed ______ for him ever since. From the age of eight, he ______ a school for the deaf and the blind, learning to read Braille (盲文). He was always ______, and when he was 16, the school said he had learned enough and sent him home. However, nothing could ______ him from learning and becoming independent. At 21, Joe moved out to live on his own, as he said, “Like a man, I am able to ______ by myself as a consultant (顾问).” He learned to cook, clean, do his own laundry and almost anything he ______, which were joyful experiences for him.

Then he met the ______ of his life. They dated three weeks before getting married. Joe called me proudly, “Even a blind man can fall in love at first sight.”
