North American back bears are shy animals. They are fearful by nature, and will usuallyrun away if they see or hear people. Because of this, it can be difficult for scientists to learnabout these animals.
In order to study black bears, researchers from New Jersey, USA, catch bears and usedrugs to help them go to sleep. Researchers then work out the size and the weight of the bear,take blood to test for diseases(疾病), remove a tooth and take it to the lab to find out its age. Fromthese studies, researchers want to find out how many bears live in New Jersey, how long theylive, and how many babies they produce.
But in Minnesota, USA, researchers study bears that are completely awake. The bears knowthe researchers' voices and they are not afraid of die research team. With the help of a few grapesto keep the bears busy, researchers can touch them to check their hearts, look at theirteeth, and do other jobs.Researchers can also walk or sit with bears for hours and make videos to learn about their everyday lives.
In both places, the main purpose is the same—to make sure there is a healthy population of black bears. But theresearch methods and the kinds of information that researchers, are able to collect arc quite different.
In the first paragraph, we can learn that North American black bears are _______.
A.shy and fearful animals | B.not found today |
C.well known to scientists | D.not afraid of people |
The word "remove" in the second paragraph probably means _____ in Chinese.
A.拔下 | B.移植 | C.清洗 | D.修补 |

C.The weight. | D.The number of babies they produce. |
In the Minnesota studies, researchers _____.
A.can never get close to the bears |
B.study the bears while they are asleep |
C.use grapes to make the bears full |
D.learn a lot about the bears' everyday lives |
What do the two studies have in common?

C.Research methods. | D.Collected information. |
To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade(遮蔽)against the sun.
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use : it became a symbol of honor and power(权力). In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.
In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power.
Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.

The son said, “Well, we have one dog and they have four. We have a pool in our garden, while they have a river that has no end. We have expensive lanterns (灯), but they have stars above their heads at night. We have only a small piece of land to live on, while they have the endless fields. We buy our food, but they grow theirs. We have high walls around our houses to protect us, but they don’t need walls, because their friends will protect them.”

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___________.
A.a star was speeding away very fast. |
B.a stars was moving away very slowly. |
C.some stars were not real. |
D.some stars were not in the Milky Way. |
Which of the following is TRUE?
A.Stars never move at all. |
B.No star in the galaxy has a fast speed. |
C.It’s hard to see the stars moving. |
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. |
B.where the Milky Way is |
C.something about the speedy stars. |
