| How do astronauts have meals? Eating in space is different from eating on the earth. The food that astronauts carry with them doesn’t look like the food you eat on the earth. Some food is carried in closed bags. It is cooked and frozen before the astronauts get it. All the water is removed from the food. In the space capsule(太空舱), the astronaut puts the water back. He “shoots” hot or cold water into the food bag with a special gun. He eats the food through a small hole in the bag. Other foods come in bite sizes. The astronaut puts a whole piece in his mouth at a time. There can be no crumb(食物碎屑) floating around the capsule. Meat, cakes and cereal often come in bite-sized pieces. Astronauts can’t drink water from open cups. The water would float in drops in the air. The water is put in the special gun. The astronaut shoots the water into his mouth. Eating in space is not easy. Astronauts must learn to eat this way. |

It is well known that everyone has his own dream as well as his own future. But do you know what future really is? I have to say that future is now. That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying: “Gain time, gain life.” Then what's time? Time is something that we can’t see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say “Time is money”, but time is even more precious (珍贵的) than money, because when money is spent, we can earn it back. But if time is gone away, it will never return. So, some of us even say time is priceless (无价的).
We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today.We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
As we all know, “Time and tide wait for no man.” If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.”Today’s hard work is the cause of tomorrow’s harvest.

Wearable gadgets (可穿戴设备) are usually high-tech equipment, which are so small that people can wear on heads or wrists.
Google Glasses is such kind of wearable gadget. It has attracted the world’s attention since being tested this year. Users can take videos and broadcast live on the Internet. There is also a GPS system in the glasses. So if you get lost you can say “OK，Glasses, where am I?” Then it will tell you where you need to go. It sounds cool, doesn’t it?
Don’t forget Galaxy Gear from Samsung, a Korean company. It is just the tip of the iceberg. This smart watch looks like a normal watch but much lighter. But Galaxy Gear needs to connect with a Samsung Smartphone or tablet (平板电脑). Its short battery life of 25 hours also disappoints (使…失望) users.
With all kinds of wearable gadgets coming into real life, it seems that wearable equipment is becoming more modern and popular. Indeed, unlike smart phones, wearable gadgets are more convenient (方便的). Their biggest advantage is that they can do most of the same things as smart phones, yet they are hands-free.
However, wearable gadgets also have their own problems. Some people are not sure whether wearing a gadget is cool. Unless you know about it, you may just think there are many crazy people talking to their wrists.
Perhaps only time will tell how these gadgets will change our lives.

Think stars don’t move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move—they are just so far away that the movement is hard to see.
But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities(奇特). It was located on the outer edge of the Milky Way, the galaxy(星系) we live in. The star was speeding away like nothing he’d ever seen. “It seemed unbelievable. No star in the galaxy has a speed like that,” Brown remembers. “I thought, oh my goodness, I have something kind of special here.”
No one had ever seen a star like this one. What does a scientist do when the results don’t make sense?
Brown didn’t give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called hypervelocity stars. Hyper means “above” and velocity has to do with speed. He and his team just found six more of these “above speed” stars, bringing to the total of 16. And, he says, he’s found even more, and is just waiting for the scientific community to confirm them.In 2005, astronomer Warren Brown found___________.

| D．Brown has never seen something special. |
The underlined word “hypervelocity” in the last paragraph probably means”_____”.
| A．匀速的 | B．超速的 | C．超重的 | D．超常的 |
The writer writes this passage to tell us____________.
| A．something about an astronomer. |
