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 _____ .

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour a week to support his young family. And the bike was also used to get groceries（食品杂货）, saving us from having to walk long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.Why was the bike so important to the couple?
| A．They used it for work and daily life. |

Beach volleyball is one of those sports that can be an exciting game to play and watch, or, can just be about some friends getting together to have a great time. It’s really easy, and all you need is sand, a net and a group of people, of any age or fitness level, who want to have fun.
Beach volleyball can be played with as few as two people on each team, making a total of four people. However, if you are less skilled and experienced in the game, it will be easier to play with a larger team. The more players you have, the less ground each person will be responsible(负责)for covering and the more time they will have to recover in between shots. If you only have a few players, each of you will get quite a workout running for the ball after each volley. If you are looking for that relaxing, fun, low-key experience, choose larger teams.
Beach volleyball is similar(相似)to regular volleyball in its rules. However, even experienced volleyball players do not realize how much more difficult it is to run and jump on sand. Since it is harder to move quickly on sand than a hard ground, play will be much slower than regular volleyball on a playground. When a player trains for beach volleyball, he will focus(专注)on building lower body strength as well as upper body. While he needs to be able to hit the ball with a great deal of power and accuracy(准确性), strengthening his legs is extremely important.
Whether you are in it for the competition, or just to have a great time with your friends, beach volleyball can be very exciting and fun. You may even start out with friends and fall in love with the sport.When you join a large beach volleyball team, you’ll_________.
| A．have as many shots as possible | B．improve your volleyball skills |
