The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.

“Racism (种族歧视) is a grown-up disease,” declares the saying on Ruby Bridge’s website along with a photo of Mrs. Bridge today, a 6-year-old girl four decades ago. In the photo, she is walking up the steps of the William Frantz Public School in New Orleans, a little black girl accompanied by two officers who protect her on her way to school.
Her name then was Ruby Nell. It was Nov. 14, 1960. She was the first black child to enroll at this all-white elementary school according to the court order to desegregate in New Orleans schools. Her story is moving -- she was a very courageous child -- and remains a significant proof against intolerance (不宽容) of all kinds. Ruby’s photo brings out another powerful image on her website: Norman Rockwells symbolic painting for Look magazine on Jan. 14, 1964, “The Problem We All Live With.”
Rockwell was an illustrator of exceptional skill and charm. He produced a vast number of unforgettable images over a long career, many of them involving children. His American kids are innocent and appealing, but often, at the same time, decidedly naughty. His method was to photograph his models, and the resulting paintings were photographic． But it is revealing to see how the artist slightly changed facial expressions from photo to oil painting in order to make his paintings communicate with the viewer. Communication, even persuasion, lay at the back of his work; this was art for effect.
“The Problem We All Live With” belongs to Rockwell’s later work, when he began openly showing his strong belief in liberty. This is a highly persuasive image. Before he arrived at the final copy, one sketch (草图) shows the little girl closer to the two officers following her than to those in front. In the finished picture, the girl seems more determined, independent, and untouched． The unfriendly tomatoes thrown on the wall are behind her now, and she, is completely unaffected．
【小题1】Ruby Nell was protected by officers on her way to school, because   .

For those who are tired of doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app (application).
Strange though it may seem — "my wife already does that" was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install a large number of internet-connected features in machines in an effort to make them "smart".
Last year, it was a refrigerator that tweeted. This year, it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.
The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owner is at work or on the bus.
Samsung says it's not just something new — the app connection actually has some practical uses.
"If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go." said spokesperson Amy Schmidt.
The company also says that with electricity rate (电价) varying depending on the time of day, more control over when the machines are used can help save money.
Perhaps, but what they will probably really accomplish is what all good technologies do — enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.
【小题1】 What can be inferred from the common response of the attendees at the CES?

Money, jewels and important documents are not the only valuable placed in banks these days. Some mothers store their breast milk in banks.
There’re ten breast banks set up across the United States, where mothers can donate their extra milk for other women’s babies. Experts say breast milk is the best food for babies. The World Health Organization says it is the only food babies should get during the first six months of life, in most cases. Breast milk is especially important for babies born too early. Sometimes these premature babies must stay in the hospital for many weeks.
James Cameron is a doctor who treats newborns at Lutheran Children’s Hospital in Fort Wayne, Indiana. He says breast milk is almost like medicine. Doctor James Cameron said, “The fact is that there are so many different proteins and specialized sugars in the breast milk that the mom’s able to make that help provide immunity. It’s very important for the health of the newborn.”
There are several reasons some mothers may not be able to breastfeed. Some are not able to produce enough milk. Others might be taking medicines or have medical problems that prevent the process.
Lucy Baur lives near Fort Wayne. She fed her milk to both her children and always had more milk than they needed. She wanted to donate to the Indiana Mothers Milk Bank in Indianapolis. But freezing and shipping milk can be costly. Then, a donor station opened near her home.
Milk donations in the United States work like this: Donors must be willing to provide almost three liters of breast milk. They freeze the milk and take it to the station. There, employees warm the milk and mix it with other mothers’ milk. Then, the milk is heated to kill bacteria. After that, the technicians test samples of all the milk to make sure it is safe and healthful. The milk is re-frozen and sent to the main milk bank. The milk bank transports the milk to hospitals to feed premature or sick babies. Donors are tested for diseases before any milk is accepted. They are not permitted to smoke tobacco, use illegal drugs or drink too much alcohol.
【小题1】The purpose of setting up breast milk banks is to_____.

Many people consider their pets members of the family and are very sad when they die, but what if you could clone your dog, cat or bird?
A scientist in New Orleans, who has proved his ability to clone other animals, is now offering the possibility to pet owners here in Wisconsin．
Scientists have not been able to clone dogs, cats or other pets, but if and when the time comes, several companies will be ready and able to do the job．
The question is: Are you ready to clone your pet? Brett Reggio is betting on it．He is working on his Ph. D at Louisian State University. He's successfully cloned a goat five times and wants to try the process on family pets．  So he started a business called Lazaron． “What Lazaron provides is the first step in the cloning process． ”He said．“It’s for curing and storing the fiberglass cells that will be used for cloning．”
“Your first reaction is yeah! I think I’d like that．” said Donna Schacht, a pet owner．
“I don’t believe you can ever replace a special love,” pet owner Paulette Callattion said．
Most pet owners will tell you freezing your pet’s  DNA in hopes of one day cloning it is a personal decision．
Scientists say that cloning your own pet doesn’t mean that the offspring（后代） will have the same intelligence, temperament（性情） or other qualities that your pet has．
【小题1】From the passage we know that scientists have ______．
