Researchers have been looking forward to using tiny flying robots to settle important tasks. The various machines could be used to help astronauts on space missions, and even to help bees with plant pollination(授粉). However, fitting the heavy electric equipment that is used to power and control the wings into the tiny robot has been challenging. Now thanks to RoboBee X-Wing—the world’s lightest aerial vehicle that can fly not tied to a power source.
Made by Harvard researchers, the insect-inspired robot weighs only 259 milligrams, has four wings whose distance is 3.5 centimeters, and stands 6.5 centimeters high. Its four small wings, which can flap up(拍动) to 170 times a second, are controlled by actuators(驱动器). They become small when the electricity passes through them. Six small solar cells, fitted above the wings to prevent them from disturbing the flight, provide the power.
RoboBee X-Wing is powered by six solar cells. To test its flying abilities, the team, led by doctor Noah Jafferis and PhD student Elizabeth Helbling, exposed the RoboBee X-Wing’s solar cells to LED lighting. To their delight, the tiny robot’s wings began to flap, and it rose, keeping a flight for about half a second. Though the robot lost its flight ability as soon as the power source was turned off, its short flight was cheered for its huge effect on the future of tiny flying robots.
However, though the current RoboBee X-Wing is a step in the right direction, it is not quite ready for main time. The researchers also hope to experiment with other power sources, such as batteries, sun light or radio frequency signals, and to add more advanced “brains” and sensor systems to navigate and complete tasks independently.
1.What can we know about small flying robots according to the first paragraph?
A.They are made to do ordinary tasks by scientists.
B.They can be used only for very dangerous task.
C.They can be powered directly by the energy of the sun.
D.It’s not easy to fit the heavy electric equipment into them.
2.Why is RoboBee X-Wing considered having a big effect on the future of tiny flying robots?
A.Because it is ready for the instant use.
B.Because it can take off and fly out of control.
C.Because it can fly not tied to a power source.
D.Because it can settle important tasks.
3.Which of the following is TRUE about RoboBee X-Wing?
A.It can’t be used in crowded places.
B.It can be used for giving directions.
C.It can use radio signals to power itself.
D.It still can’t be used widely at present.
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Science.
C.Education. D.Health.

How hard we have all prayed(祈祷) to grow up quickly, and looked forward to the happy days of being a grown-up and enjoying the many interests that a youth should have.
At last, you have grown up. At least you are no longer a child. They call you “young lady”. You then enjoy the pleasure of being a young lady. You are proud of being a grown-up teenager. People welcome you-this young lady-heartily. You are glad that your prayer has been answered.
But there is always something that troubles you a lot. You say; “Papa and Mama, give me some money please. My pocket money is all gone already.”
“No”, they say, “your age is a dangerous age. If you have too much money to spend, it won’t do you any good.” Then you have to stay at home because you dare not go out with an empty pocket.
Another time you tell your grandma, “Grandma, see, I am a grown-up now.”
“Good, now, you can sit here and knit (编织) this for me while I go and have a rest.” To show that you are no more a child, you have to sit there the whole afternoon doing the work, which only a grown-up can do. After an hour, you find it hard to do, and give the knitting basket back to your grandma. Your grandma criticizes your work. You hear what she says, “Such a big girl can’t do such easy work.” You wish then you were a child again.
But the fact is, you are growing up, and you can’t help it. That’s the way it goes!
