　　Which animal has the fastest snapping jaw(突然合住的颚)? If you're guessing a shark or perhaps a larger animal, you'll have to think smaller．The trap-jaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second．Another way to think about this is that the ant's jaws close at 125 to 233 kilometers per hour．That's 2,300 times faster than the blink of an eye．

　　Scientists were able to measure the amazing jaw speed using high-speed video techniques．Sheila Patek, a biologist, says the key is that the jaws have a springy(有弹性的)system, which is critical in getting explosive(爆发性的)speeds．

　　Consider a bow and arrow．If you try to throw an arrow with your arm, it won't go very far．If you use a bow, elastic energy stored in the bow is freed almost immediately when you let go of the arrow with your finger．That's exactly what really fast organisms are doing．

　　Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move．As the ant closes its jaws, it uses them to push off the ground－all faster than the eye can see without slow motion video．A snap of the jaw can send an ant up to 8.3 centimeters into the air．That's like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once．It would be hard for their enemies to grab just one．

(1)

The fast speed of the trap-jaw ants' jaws lies in ________．
[　　]
A．	their light bodies
B．	their springy systems
C．	their living environment
D．	the length of their jaws

(2)

What does the passage use “a bow and arrow” as an example to show?
[　　]
A．	How an arrow gets so much energy to fly．
B．	Why the trap-jaw ants have a springy system．
C．	Why the trap-jaw ants' jaws move so fast．
D．	How a bow and arrow works．

(3)

Which of the following things may amaze the scientists most?
[　　]
A．	How high the ants can leap by using their jaws．
B．	How quickly the trap-jaw ants can move on the ground．
C．	How wonderfully the springy system in the trap-jaw ants' jaws works．
D．	How quickly the trap-jaw ants can grab food or enemies．

(4)

According to the passage, the trap-jaw ants' jaws keep them safe because ________．
[　　]
A．	they can catch their enemies easily with their jaws
B．	their jaws make them difficult to recognize
C．	their jaws help them to find food easily
D．	their jaws help them to escape from their enemies

　　CCTV anchorman LuoJing died of cancer on June 5, 2009 at the age of 48．

　　In 1983, graduating from Beijing Broadcasting Institute, he began his career as a prime time newscaster for CCTV．Over the past decades, as an icon of China's broadcasting industry, LuoJing's modest image and clear voice left unforgettable memories with his audience．

　　In 2008 when he was diagnosed as having lymph(淋巴)cancer, he felt it too awful, for two weeks later he was to run the torch, he asked doctors to keep the secret in order for him to complete the task of the Olympic torch．Finally, not only did he complete the task, but he participated in a series of voice-overwork in the Olympic Games opening ceremony．After that, he frankly said to the leader the next day, “I have completed the task and I am going to hospital today．”

　　Broadcast sowing rate of the News Network used to be 180 words a minute, but increases to 300 words a minute, which is beyond most people's ability．What's more, terror is the strict limit of time．Sometimes after a piece of news is broadcast, there is a few seconds left, when staff hand a message press release(新闻稿)．The host must strictly control the time to broadcast the unexpected news．As soon as his voice fades, the program turns into the following images without one more second or less．In such high-intensity work environment, with the professional he worked for 26 years without any error．

　　In life, we seldom mention comedy without tragedy, laughter without tears, and joy without sorrow．Though the passing of LuoJing brings us pain, it's only fitting to remember his smiles with happiness．He's been taken from us much too soon, but he leaves us what he's beenworking for．

When did LuoJing go to hospital?
[　　]
A．	As soon as he ran the torch．
