Although problems are a part of our lives, it certainly doesn’t mean that we let them rule our lives forever. One day or the other, you’ll have to stand up and say – problem, I don’t want you in my life.
1. Problems with friends, parents, girlfriends, husbands, and children – the list goes on. Apart from these, the inner conflicts within ourselves work, too. These keep adding to our problems. Problems come in different shapes and colors and feelings.

Scientists at Harvard University have recycled a kidney(‘肾)-in a rat. The researchers removed a kidney from a dead rat. Later, the renewed kidney was put into a living rat. It wasn't perfect. It did, however, show signs of working like a kidney should.
"It's really beautiful work," Edward Ross, a kidney researcher at the University of Florida in Gainesville, told Science News. He didn't work on the new study.
Kidneys are bean-shaped and act like guards in the body. They clean the blood by removing waste and extra water. Every day, an adult's kidneys filter(过滤) enough blood to fill a bathtub half full. Along the way, they produce eight cups of urine(尿) from that waste and water. When a person's kidneys fail, all of that waste stays in the body. Such patients can quickly become very sick and die, unless they are regularly connected to a machine that filters their blood.
At any given time, about 100,000 people in the United States are waiting for a replacement kidney. But healthy donated kidneys are difficult to get. Either a living person must donate one, or a kidney must be removed from someone who just died and earlier had agreed to the donation. In either case, people receiving new kidneys face the risk that their bodies will reject the donated ones.
But there may be another option. Researchers use knowledge of living things to grow or improve tissue that can aid human health. Harald Ott's team at Harvard started with a "used" kidney.
Scientists added kidney cells from rats and blood vessel cells from people to the matrix（母体）. These cells attached themselves and began to multiply. Before long, they formed new kidney tissue.
The scientists placed this renewed kidney into another rat. There it produced a small amount of urine. This experiment shows that the lab-grown kidney can do at least some of the work performed by a healthy kidney.
The results are a promising first step toward helping people with serious kidney problems. "This is still very early, but they've come a long way," Ross said.
1.What can we infer from Paragraph l?
A. Biology is a new and helpful science.
B. It's hard to put the rebuilt kidney into the rat.
C. Kidneys are very important to our life.
D. A used kidney may be recycled for new life.
2.What does Paragraph 3 mainly talk about?
A. The relationship between kidneys and health.
B. The difficulty of curing serious kidney diseases.
C. The function and importance of kidneys.
D. The methods of curing kidneys diseases.
3.For what purpose does the author use the figure 100,000 in Paragraph 4?
A. To stress used kidneys are hard to get.
B. To show the great need for healthy kidneys.
C. To explain many American people get kidney diseases.
D. To call on people to donate kidneys.
4.Which of the following is true according to the text?
A. The scientists are satisfied with the result of the experiment.
B. Ross is a kidney expert who is involved in the experiment.
C. The function of the renewed kidney is the same as a healthy kidney.
D. The renewed kidney produced a great deal of urine.
A machine that takes sweat-laden clothes and turns the moisture（分子） into drinking water is in use in Sweden. The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane(膜) designed to only let water molecules get through.
Since its Monday launch, its creators say more than 1,000 people have “drunk others’ sweat（h汗液）" in Gothenburg. They add the liquid is cleaner than local tap water.
The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.
The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik. He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology.
"It uses a technique called membrane distillation(膜蒸馏)," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine(尿液) - but our machine was cheaper to build. Volunteers have been sampling the treated sweat since the start of the week in Gothenburg .“The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful."
The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament. MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt(惊人的表演) - said the machine had helped raise awareness for UNICEF, but in reality had its limitations.
"People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for sweat is greater than the supply. And the machine will never be mass produced - there are better solutions out there such as water purifying pills."
1.What can we infer from the passage ?_______.
A. The water processed by the machine is cleaner than local tap water .
B. The machine can help raise awareness of lacking water in the world .
C. The machine is cheaper than the similar one on the International Space Station
D. The amount of water the machine produces is roughly a mouthful.
2.What is the main idea of the fifth paragraph ?
A. How the machine works.
B. Who developed the machine.
C. How the machine was invented.
D. Why the machine was invented..
3.What does Mattias Ronge think of the machine?____
A. The machine can solve the severe water shortage in the world.
B. People do not like the water the machine processes
C. The machine should be used in rather hot areas in summer.
D. The machine is not worth popularizing.
