PERTH—Search crews will send a submarine(潜航器)deep into the Indian Ocean on Monday for the first time to try to determine whether signals detected by sound-locating equipment are from the missing Malaysian plane's black boxes, the Australian head of the search said.
Angus Houst on said the crew on board the Ocean Shield will send the underwater vehicle sometime Monday evening. The Bluefin 21 submarine can create a sonar(声呐)map of the area to chartany wreckage(残骸)on the seafloor.
The move comes after crews picked up a series of underwater sounds over the past two weeks that were consistent with an aircraft's black boxes.
“We haven’t had a single detection in six days, and l guess it’s time to go under water,” said Houston.
“Analysis of the four signals has reduced the search area on the ocean floor. The experts have therefore determined that the Australian Defense Vessel Ocean Shield will stop searching with the Towed Pinger Locator(拖曳声波定位仪)later today and use the underwater vehicle Bluefin 21 as soon as possible," he said at a news conference in Perth.
But Houston warned the switch to the submarine will not automatically "result in the detection of the aircraft wreckage. It may not.”
He said the submarine will take 24 hours to do each task, including two hours to dive, 16 hours to search the bottom, then two more hours hack up and four hours to download data.
Recovering the plane's flight data and cockpit(飞行员座舱)voice recorders is necessary For investigators to try to figure out what happened to Flight 370, which disappeared on March 8.
Houston said the search using the submarine will be a slaw and painstaking process.
The submarine takes six times longer to cover the same area as the pinger locator,and will need about six weeks to two months to examine the present underwater zone. The signals are also coming from 4,500 meters (15,000 feet) below the surface, which is the deepest the submarine can dive.The submarine will be sent deep into the Indian Ocean on Monday to _____ .
| A．create a sonar trap of the area |
| B．pick up underwater sounds |

| B．can find the aircraft wreckage within 24 hours |
| C．will recover the plane's flight data and voice recorder |
| D．can dive to a depth of no more than 4,500 meters |
The underlined sentences in the passage indicate that______.
| A．the switch of the submarine may not function properly |
| B．the Ocean Shield will switch to submarine when it is necessary |
| C．the submarine will detect the wreckage of the plane automatically |
| D．the detection of the wreckage can't be guaranteed by using the submarine |

For a while, my neighborhood was taken ever by an army of joggers(慢跑者). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. “Come on!” My friend Alex encouraged me to join him as he jogged by my house every evening. “You’ll feel great.”
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet take a real pounding（重击）ruining down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a
nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts. “Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn’t just the first week: it was practically every day for two months. I never got past the pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise, and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.

If you’re a male and you’re reading this, congratulations! You’re a survivor. According to statistics，you’re more than twice as likely to die of skin cancer than a woman，and nine times more likely to die of AIDS.
There're many reasons for this--typically，men take more risks than women and are more likely to drink and smoke but perhaps more importantly, men don’t go to the doctor.
“Men aren't seeing doctors as often as they should，” says Dr. Gullotta. This is particularly so for the over-40s, when diseases strike. According to a recent survey, 95％of women aged between 15 and early 40s see a doctor once a year, compared to 70％of men in the same age group.
“A lot of men think they’re unbeatable，”Gullotta says. “They only come in when a friend drops dead on the golf course and they think, if it could happen to him …”
Then there’s the ostrich（鸵鸟）approach. “Some men are scared of what might be there and would rather not know,” says Dr. Ross Cartmill.
“Most men get their cars serviced more regularly than they service their bodies,” Cartmill says. He believes most diseases that commonly affect men could be found by preventive examinations.
“Prevention is cheaper in the long run than having to treat the diseases. Besides, the final cost is far greater，it’s called death.”

D. Men aren’t as cautious as women in face of danger.
3.Which of the following best completes the underlined sentence “if it could happen to him…” （in Para 4） ?
A. it could happen to me，too.
B. it would be a big misfortune.
C.I should avoid playing golf.
D.I should consider myself lucky.

C. Refusal to get medical treatment for fear of the pain.
D. Unwillingness to find out about one’s disease because of fear.
A murder will occur this weekend in the peaceful seaside town of Langley, Washington. In fact, a murder has occurred there every February for the past 25 years. But don’t panic! It’s all part of the town’s yearly Mystery Weekend.
