【推荐1】For thousands of years, humans have explored the Earth. Nowadays, we are exploring space. Astronomers (天文学家) are modern—day explorers. Now, many astronomers are looking for new planets and new places of humans to live in the future. But where do astronomers start looking?

First of all, astronomers look for a star. That’s because our own Earth moves around a star (the Sun). More importantly, it is the correct distance (距离) from the Sun for heat and light. So when astronomers have found the star, they look at the planets around it. In recent years, astronomers have found nearly 400 new planets with stars. However, many of these planets are either too near to the star or too far away.

However, if the planet is in a good position, astronomers look for three key things: water, air and rock. Water is important because all life needs water. Humans can drink it and they can also grow plants with water. And plants produce air for humans to breathe and food to eat. Rock on a planet is also important. That’s because there is often water under the rock.

After many years of scrutinizing, astronomers have found a planet that is similar to the Earth. It’s Gliese 581g and it’s near a star. The astronomers think it has water and rock and the average (平均的) temperature is between -31℃ and -12℃. That’s cold，but not colder than Antarctica or Arctic Circle, for example, Gliese 581g is bigger than the Earth. A year on Gliese 581g is only 37 Earth days instead of 365. But astronomers do not think there are big differences and some them thing Gliese 581g will be a new Earth. However, Gliese 581g is twenty light years from the Earth.

1. What do astronomers have to find first before starting to look for a new place for humans to live?

A．A new star.

B．A new planet.

C．Some heat.

D．Some light.

2. What does the rock on a planet tell us?

A．The star is a right position.	B．We may discover water under it.
C．The planet is too near to the Sun.	D．There can be air around the rock.

3. What does the underlined word “scrutinizing” mean in the last paragraph?

A．discussing

B．waiting

C．looking

D．traveling

4. What’s the main idea of the text?

A．Gliese 581g is already a new Earth.	B．There are planets similar to our Earth.
C．Water, air and rock are important.	D．Astronomers are looking for a new Earth.

【推荐2】People around the word felt excited on the night of April 10, 2019. For the first time in history, people saw a photo of a black hole. The photo became popular at once. But do you know it has something to do with a computer scientist Katie Bouman. Without her, there won’t be this photo.

Black holes are very far from us, so it is very difficult to take photos of them. It’s like taking a photo of an orange that is on the moon. Many scientists had tried. However, none of them succeeded.

These failures didn’t stop Bouman from trying. Several years ago, she started working on a special computer program. During the part years, she has improved the program many times. Finally, it turned telescope data (望远镜数据) into a photo of a black hole.

Bouman has received lots of praise because of her work. The young woman, however, is modest. She said the success mainly depends on her team. “None of us could do it alone,” she said.

Would you like to make history as Bouman did? Set a goal for yourself and work hard at it. Maybe you will make it come true in the future.

【推荐1】Have you seen Avatar（《阿凡达》）? It’s a popular 3D movie, and you may have to wear 3D glasses to see it. The 3D glasses make the images（图像）from the movie look as if they were coming straight towards you.

More and more 3D movies are coming to theaters. Some say that 3D TV sets will come into our homes in the near future. 3D technology can make TV and movies more exciting. However, people with eye problems may get headaches if they spend too much time watching 3D movies. Why?

When we look at an object（物体）, each eye sees it at a different angle（角度）. Our eyes send the two images to our brain（大脑）, and the brain puts them together. 3D technology uses two film projectors（投影机）. One projects a left-eye-image and the other projects a right-eye-image. 3D glasses allow us to see a different image in each eye. So, when we are watching a 3D movie, our brain can’t put together the images sent to our eyes. The brain needs to work harder at “reading” the images. That makes it easier for people with eye problems to get dizzy（头晕的）or have headaches. A famous eye doctor said if your eyes can’t focus（聚焦）on the same object at once, you will have trouble watching 3D movies.

【推荐2】Did you climb a tree when you are young? How did you feel? What if you have a serious “tree climbing class” at school? A primary school in Hangzhou has opened a “tree climbing class” recently. Quite a lot of people are interested in the special class.

“Go! Go for it! You’re almost to the top!” On Monday morning, children at Xuezheng Primary School in Hangzhou get together around a tall tree. They are cheering on their classmates who are climbing the tree. On the big tree, there are wooden stirrups (脚蹬) (No harm will come to the tree). PE teachers help the children put on protective gear to keep them safe, and then they start the tree climbing class happily.
