For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives.

“A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?” asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts. These parts are not made of steel; they are the real things --- living cells, tissue, and even organs.

Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999，when a research group at North Carolina’s Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs 一 from kidneys to ears.

The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient’s body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient’s own cells and will not be rejected by the body’s immune system.

Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart. Dr. Atala’s medical team has reported long-term success with bioengineered bladders implanted into young patients with spina bifida (a birth defect that involves the incomplete development of the spinal cord). And at the University of Michigan, H. David Humes has created an artificial kidney.

So far, the kidney procedure has only been used successfully with sheep, but there is hope that one day similar kidney will be implantable in a human patient. The continuing research of scientists such as these may eventually make donor organs unnecessary and, as a result, significantly increase individuals'chances of survival.

1. In the latest field of regenerative medicine, what are replacement parts made of?

A. Cells, tissues and organs of one’s own.

B. Rejected cells, tissues and organs.

C. Donated cells, tissues and organs.

D. Cells, tissues and organs made of steel.

2.What have scientists experimented successfully on for a bioartificial kidney?

A. Patients. B. Rats. C. Soldiers. D. Sheep.

3.Why is generative medicine considered innovative?

A. It will strengthen the human body’s immune system.

B. It will provide patients with replacement soft tissues.

C. It will make patients live longer with bioartificial organs.

D. It will shorten the time patients waiting for a donated organ.

4.What is the writer’s attitude towards regenerative medicine?

A. Doubtful. B. Reserved. C. Positive. D. Negative.

Since American students have been introduced into the era of the Massive Open Online Course, the opportunity for cheating appears greater than ever. The all-knowing Google search engine is within easy reach. So how can a teacher handle such a large number of examinees so far away, let alone searching out cheaters taking tests across the Internet?

Using technology, of course. While special services via webcam (摄像头) and cheating detecting software have been developed now, Mettl, an online company, has developed advanced techniques for netting cheaters, which the company claims are even more reliable and easier to use. Whatever small attempt to cheat, he or she will be found out.

Mettl has adopted a mass of technologies on its test-taking platform, creating a mini monitoring state in an exam. Here’s how it works: A test-taker signs on to Mettl and selects his／her exam from the site’s library of pre-loaded tests. Facial and keystroke recognition technology confirm the person that has signed in is the very person, and the system records both the test-taker (through the webcam) and the test-taker’s screen throughout the test.

Mettl’s technology uses the test-taker’s webcam to detect how many people are using the computer. Soon, it will track eye movement well enough to sense whether the test-taker is looking away from the screen, perhaps to consult a smart phone or a friend in secret. Mettl also monitors the test-taker’s screen and can detect when the test-taker has changed a computer or moved from the test. The system will soon be able to record sound, detecting whether the test-taker is talking or being talked to.

If any wrongdoings are detected, the system flags the incident and reports it back to the test’s administrator. This can bring any number of things, depending on the test-giver’s wishes: a complete shutdown of the exam, a warning message that appears on the test-taker’s screen, even human instructions from the control center.

Mettl is hoping its technology will help it break into the country’s big MOOC markets.

Last spring, members of Alaska’s Troop 34, based in Fairbanks, trudged (跋涉) out into the snowy wilderness to take part in their state’s Take a Kid Trapping program. In many parts of the state, beavers （海狸）are pests and need to be controlled.

The 10－to－12－year－old girls found out where beavers lived, set traps, and skinned the two animals they caught. The girls hope to catch ten more beavers so that the entire troop can make mittens and hats with the fur. They also want to cook beaver meat.

Troop leaders and members say the Scouts are doing a good deed by helping control the state’s beaver population. But animal－rights activists say trapping is cruel. They want the Girl Scouts to stop in their tracks.

Beavers aren’t only causing a problem in Alaska. Residents in Sampson County, N.C. , have turned to a local committee to help them battle the growing beaver population there.

County landowners are frustrated after the county spent more than $ 50,000 in eight years trying to reduce the beaver population through a government program. The joint state and federal program included paying money to trappers for every beaver carcass they trapped.

Many local residents say that the program didn’t work because there were too few trappers. That’s why the county set up its own committee to investigate other ways to control the area’s beaver population.

The county will rely on its own beaver－trapping program. It has hired a trapper to set traps in various areas. The county will pay $10 for every beaver carcass.

Why do many people say that beavers are a nuisance? For beavers to survive, they need lots of water. Water provides the large rodent （啮齿动物）with a place to hide from meat – eating animals. Beavers also store food underwater for the winter. When there’s not enough water in a particular area, beavers get busy building dams.

Beaver dams can cause major flooding and damage to the surrounding countryside as the animals cut down trees to use in their construction projects. Beavers build canals to transport heavy objects.

1.What is Alaska’s Troop 34?

A．A team of the Boy Scouts. B．An army.

C．A team of the Girl Scouts. D．A sports team.

2.Why does the troop hope to catch ten more beavers?

A．To fulfill their task.

B．To sell them for money.

C．To get enough fur.

D．To exchange them for mittens and hats.

3.Which of the following statements is true?

A．Sampson County has to find a new way to control the beaver population there.

B．The government program in Sampson County has proved to be a success.

C．The local government has controlled the number of beavers in the County.

D．More and more trappers now start to set traps in Sampson County.

4.Local residents hate beavers because they can ___________.

A．cause damage to dams

B．block up canals with heavy objects.

C．do great harm to construction projects.

D．badly damage the environment and cause floods.

Being Authoritative (由权威的) Parents

Phrases like “tiger mom” and ‘‘helicopter parent” have made their way into everyday language．Many of us find ourselves drawn to the idea that with just a bit more parental hard work and effort, we might turn out children with bright futures．But is there anything wrong with a kind of “overparenting style”?

Parental involvement has a long history of being studied． Many of the studies, conducted by Diana Baumrind, a famous psychologist at the University of California, Berkeley, have found that a good parent is the one who is involved and reacts to her child in a positive way, who sets high expectations but gives her child independence．These “authoritative parents” appear to hit the sweet spot of parental involvement and generally raise children who do better academically, psychologically and socially than children whose parents are not strict and less involved, or controlling and more involved． Why is this parenting style so successful?

Authoritative parents actually help improve motivation in their children．Carol Dweck, a social psychologist at Stanford University, has done research that indicates why authoritative parents raise more motivated children．In a typical experiment, Dr．Dweck takes young children into a room and asks them to solve a simple puzzle．Most do so with little difficulty．But then Dr．Dweck tells some, but not all, of the kids how clever they are．As it turns out, the children who are not told they’re smart are more motivated to solve increasingly difficult puzzles．They also show higher levels of confidence and show greater progress in puzzle-solving．

As the experiment suggests, praising children’s talents and abilities seems to shake their confidence．Dealing with more difficult puzzles carries the risk of losing one’s status as “smart”．Dr．Dweck’s work strongly supports that of Dr．Baumrind, who also found that reasonably supporting a child’s independence and limiting interference (干涉) causes better academic and emotional results．

The central task of growing up is to develop a sense of self that is independent and confident．If you treat your young child who is just learning to walk as if she can’t walk, you reduce her confidence．Allowing children to make mistakes is one of the greatest challenges of parenting．It is easier when they are young．The potential mistakes carry greater risks, and part of being a parent is reducing risk for our children．

1.According to the passage, a “tiger mom” ______．

A． helps her children realize their dreams

B． speaks her children’s everyday language

C． places reasonable expectations on her children

D． pays close attention to her children’s experiences

2.It is implied that controlling style of parenting may _____．

A． face more challenges of children

B． foster independence in children

C． cause more problems in children

D． lead to children’s academic success

3.The example of the children doing the puzzles suggests that ______．

A． a good game plays a big role in training young minds

B． overpraising makes children less motivated and confident

C． puzzle-solving can give children the motivation they need

D． bright children usually show less confidence in difficult games

4.The last paragraph tells us that ______．

A． children should not be given much freedom

B． parents should not increase the risk of challenging

C． parents should allow their children to learn from mistakes

D． children should correct mistakes with the help of their parents

When Kerry and Sam met again two years later， each was pleased to see ____．

A． the other B． others

C． another D． other
