It’s a long-awaited day for China. The navy now has its first aircraft carrier(航空母舰), Liaoning.

It’s a unique experience to get to know the life in the carrier. The carrier is just like a small city on the sea. It has all the functions for daily life. There are 4 words to sum up its characters: big, small, much and high. The carrier Liaoning is such a huge one that the total length of the whole corridor（过道）could reach over 20 kilometers. But the living space for the sailors（水手）is quite small. That’s because the carrier is designed for researching purposes, rather than comfortable living. Over 1,000 sailors, both men and women, are living onboard. They are arranged among over 3,000 tiny rooms below the deck. For visitors, it’s so easy to get lost. So the first thing the new sailors have to learn is their way around. The number of female sailors is much less than that of the males, taking about 5 percent of the total. But they play a key role in carrying out some special missions.

Also, you will be surprised by the high level of education of today’s sailors. The captain said that over 90 percent of the sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s. The whole team is young but vigorous. The complex work on the carrier requires high management abilities for the commanders onboard(在船上).

They spent most of the important       work on dictionaries. They spent nearly all their lives trying to      words for their dictionaries. For them, it was a wonderful journey. The largest dictionary in the world is Oxford English Dictionary（牛津字典）. The        for this dictionary came from an important meeting in Britain in 1857. twenty-two years later, Oxford University asked James Murray to be the editor（编者）of its new dictionary. Murray had never been to      . At the age of fourteen, he left his village school in Scotland and taught himself while working in bank.       he became a great teacher. After Oxford gave him the job. Murray had a small house       in  his garden to do the work. Every morning, Murray got out of bed at five o’clock and      in the small house several hours before breakfast. Often he would work into the night. Murray hoped to finish the new dictionary in ten years but after five year, he was       adding（增加）words for the letter “A”! He worked on the dictionary       he was very old. Forty-four years later, in 1928, other editors finished the dictionary.

Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.

Now scientists say the microbes on our hands could be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal.

Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands.

When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away.

Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌) a surface just by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.
