More than four decades ago，British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that groundbreaking moment，more than four million babies have been born through IVF（in vitro fertilization）（体外受精）and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize in Physiology or Medicine.

The prize for Dr. Edwards，who was given a Daily Mirror Pride of Britain Award in 2008，includes a ₤ 900，000check. The Nobel Assembly described IVF as“a milestone in modern medicine”.

With the help of fellow scientist Patrick Steptoe，the Batley-born physiologist developed IVF — leading to the birth of the world's first test-tube baby. Dr. Steptoe died 10 years later but their work has given hope to millions of couples.

It was a scientific breakthrough that transformed-the lives of millions of couples. They said，“His achievements have made it possible to treat infertility，a disease which makes humans unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10%of all couples worldwide.”

Louise Brown，the world's first test-tube baby，made international headlines when she was born in Oldham，Greater Manchester，in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.

IVF is the process where egg cells are fertilized outside the body before being implanted in the womb（子宫）. After a cycle of IVF，the probability of a couple with infertility problems having a baby is one in five — the same as healthy couples who conceive（怀孕）naturally.

Professor Edwards，who has five daughters and 11 grandchildren，began his research at the University of Cambridge in 1963，after receiving his PhD in 1955. He once said,“The most important thing in life is having a child.  Nothing is more special than a child.”With the help of Patrick Steptoe, Prof. Edwards founded the Bourn Hall Clinic in Cambridgeshire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain receive IVF and 11,000 babies are born as a result of the treatment.

But his work attracted widespread criticism from some scientists who said it was“unethical and immoral”.

Martin Johnson, professor of Reproductive Sciences at the University of Cambridge, said the award was “long overdue”. He said,“We couldn't understand why the Nobel Prize has come so late but he is delighted — this is the cherry on the cake for him.”

Professor Edwards was too ill to give interviews but a statement released by his family said he was“thrilled and delighted”.

Five Facts About Goal Setting

As we all know，goal setting plays an important role in realizing our dreams. However，we don't know exactly how to deal with it. The following tips on goal setting can help make it easier to set and reach goals：【小题1】

When it comes to making a change，the people who succeed are those who set realistic and specific（具体的）goals. "I'm going to recycle all my plastic bottles，soda cans，and magazines" is a much more realizable goal than "I'm going to do more for the environment". And that makes it easier to stick with.

It takes time for a change to become a stable habit.

It will probably take a couple of months before any changes become a regular part of your life. 【小题2】That's because your brain needs time to get used to the idea that this new thing you're doing is a part of your regular routine.

Repeating a goal makes it stick in your mind.

Say your goal out loud each morning to remind yourself of what you want and what you're working for. 【小题3】Every time you remind yourself of your goal，you're training your brain to make it happen.

Pleasing other people doesn't work.

【小题4】You have to do it because you want it，not because a girlfriend，boyfriend，coach，parent，or someone else wants you to.It will be harder to stay on track and motivated if you're doing something out of duty to another person.

Roadblocks don't mean failure.

Mistakes are actually parts of the learning process as you retrain your brain into a new way of thinking. 【小题5】But that's OK—it's normal to mess up or give up a few times when you are trying to make a change. So remember that everyone slips up（疏忽）and don't beat yourself up about it. Just remind yourself to get back on track.

   The sea is home to billions of plants and animals. Many live only near the sunlit surface. Oceanographers sort marine (海洋的) living beings by dividing them into two main groups: plants and animals.

There are two general types of plants found in the ocean, those having roots that grow in the ocean bottom and those not having roots which simply float around with water. The rooted plants in the ocean are only found in shallow waters because there is not enough sunlight to maintain photosynthesis (光合作用) in deeper waters. Since sunlight does not pass more than a few hundred feet into the ocean, most of the ocean is unable to support rooted plants.

The most plants in the ocean are known as phytoplankton (浮游植物群落) . These are usually single-celled, small floating plants that float throughout the surface waters of the ocean. To grow, phytoplankton need nutrients from the sea water and lots of sunlight.

Marine animals are divided into three groups: zooplankton, nekton, and benthos. Zooplankton are floating animals and are usually small; however, they can grow to fairly large size. The jellyfish and the Portuguese man-of-war are examples of larger types of zooplankton which are unable to move themselves effectively.

Nekton are the free swimmers and probably the largest part of familiar animals found in the ocean belong to this class. Common fishes, octopuses, whales, eels and squid are all examples of nekton.

The third type of sea animals spends their entire life on the bottom of the ocean. This group of marine animals is called benthos. Some of these creatures, such as lobsters and snails, may be able to move about on the bottom but their lifestyle is so closely linked with the ocean floor that they are unable to survive away from this environment.

Children find meanings in their old family tales.

When Stephen Guyer's three children were growing up，he told them stories about how his grandfather，a banker，_____ all in the 1930s，but did not lose sight of what he valued most. In one of the _____ times when his strong-minded grandfather was nearly _____，he loaded（装载）his family into a car. And he _____ them to see family members in Canada with a _____，“there are more important things in life than money”.

The _____ took on a new meaning recently when Mr. Guyer moved to a _____ house from a more expensive and comfortable one. He was _____ that his children，a daughter，15，and twins，22，would be upset. To his surprise，they weren't. _____，their reaction echoed（类似）their great-grandfather's. What they ______ was how warm the people were in the house and how ______ their heart was accessible.

Many parents are finding family stories have surprising power to ______ children through hard times. Storytelling experts say the phenomenon reflects a growing ______ in telling tales，evidenced by a rise in storytelling events and festivals.

A university ______ of 65 families with children aged from 14 to 16 found kids' ability to ______ parents' stories was linked to a lower rate of anger and anxiety.

The ______ is telling the stories in a way children can ______ them. We're not talking here about the kind of story that ______，“When I was a kid，I walked to school every day uphill，barefoot in the snow.”Instead，we should choose a story suited to the child's ______，and make eye contact（接触）to create“a personal experience”. We don't have to tell children what they should ______ from the story and what the moral is.
