“ I think we are knocking at the door of immortality,” said Michael, a professor and author of two books on human life expectancy. “I think by 2075 we will see it and it’s no longer a dream. Human’s life expectancy may have not limit.”
At the meeting in San Francisco, Donald Louria, a professor at New Jersey Medical School said advances in using genes as well as other technology make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said. “Some have suggested that there is no limit and that people could live to 300 or 500 years.”
However, many scientists are doubtful about it and say the human body is just not designed to last more than about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and other parts of the body will finally lead all humans to death.
Scientists also hold different opinions on what kind of life man might live. “If you pass 120, you know; could you be healthy enough to have good quality of life? It’s a big question.” said Leonard Poon, director of the university center. “At present people who could get to that point are not in good health at all.”

解析
试题分析：本文讲述的是科学家在研究人类是否能够活得更长更健康，以及不同的人对此问题的不同的反应。
小题1:猜词题：根据本句we are knocking at the door of immortality (永生),指我们敲响了永生的门，说明我们已经了解到了一些关于永生的秘密，结合第一段内容可知C正确。
小题2:细节题。根据第二段最后3行“ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years说明他认为人类永生是有可能的，故D正确。
小题3:A 主旨大意题。本文讨论的主要就是人类在未来是否可以活的更久一点，故A项正确。
小题4:推理题。从最后一段的句子：If you pass 120, you know; could you be healthy enough to have good quality of life?可知这句话是超过120岁。故B正确。
点评：对于人类是否可以活得更为久远，文章中给出了答案。属于科普类的短文，此类文章的最大的障碍是词汇以及考生对阅读内容的不熟悉，需要考生在阅读的时候有足够的耐心。要养成在上下文串联中猜测词义的能力，根据上下文中出现的同义词，近义词，反义词，以及词义的解释来理解生词。同时要抓住文章的中心，不要受其他信息的影响。要根据题目及选项以及文章的上下文串联合理的判断推理。

举一反三
Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.
Dr. Worm acknowledges that these figures are conservative (保守的). One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise.
Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine biologists, that of the “shifting baseline”. The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.
小题1:The aim of the extinction of large prehistoric animals is to suggest that _______.
| A．large animal were not easy to survive in the changing environment |
| B．small species survived as large animals disappeared |
| C．large sea animals may face the same threat today. |
| D．Slow-growing fish outlive fast-growing ones |
| A．the stock of large predators in some old fisheries has reduced by 90% |
| B．there are only half as many fisheries are there were 15 years ago |
| C．the catch sizes in new fisheries are only 20% of the original amount |
| D．the number of larger predators dropped faster in new fisheries than in the old |
| A．fishing technology has improved rapidly |
| B．then catch-sizes are actually smaller then recorded |
| C．the marine biomass has suffered a greater loss |
| D．the date collected so far are out of date. |
| A．people should look for a baseline that can’t work for a longer time |
| B．fisheries should keep the yield below 50% of the biomass |
| C．the ocean biomass should restore its original level. |
| D．people should adjust the fishing baseline to changing situation. |
| A．management efficiency |
| B．biomass level |
| C．catch-size limits |
| D．technological application. |
Here are some basics that will help guide them their entire lives:
Show them the future. If your 13-year-old girl were to save $1.000,invest(投资)it at 8% and add $100 every month, by the time she’s 65,she would have $980,983!
Be careful of credit(信用).Credit cards can help you buy necessary things and build a credit history, but they must be used responsibly, which means paying off your debt in time. Explain to your children that when you buy something using a credit card, you can easily end up paying two or three times what you would have paid if you used cash.
Teach patience. Suppose your child wants a new bicycle that costs $150.Rather than paying the cash, give him some regular pocket money and explain that by putting aside,say,$15 each week, he will be able to buy it for himself in only ten weeks.
Provide incentive. Tell your children the importance of saving. “For every dollar he or she agrees to save and invest rather than spend, you agree to add another dollar to the pot,” says Cathy Pareto, expert in money planning.
Explain your values. Values and money are deeply intertwined, says Eilleen Gallo,co-author of The Financially Intelligent Parent. When your child demands that you buy something, explain why you really don’t want to buy it.“You might say, ‘I’d rather save that money for your education,’” advises Gallo. Every time you spend or don’t spend money, you have a chance to share your values.
小题1:The writer gives some basics to help________ in a proper way.
| A．parents teach their children how to deal with money |
| B．children follow their parents’ instructions |
| C．children manage their money |
| D．parents save their money |
| A．give him some regular pocket money |
| B．encourage him to put money away for it |
| C．explain to him the importance of investment |
| D．tell him to save some money by using a credit card |
| A．honor | B．praise | C．excitement | D．encouragement |
| A．Parents want to know how to educate their children. |
| B．He wants to share his good ideas about money matters. |
| C．He thinks money management the most important for children. |
| D．Parents care Little about their children’s management of money. |
Glen, a teacher, realized this was a 38 moment about the importance of making people feel _39 ． He asked his class to imagine they were about to _40 and to write a note "telling someone how and why you _ 41 him or her."
Sandy, who had a 42_ relationship with her mother, decided to write her _43 . Her letter read: "We"ve had some 44_ times and I haven"t always been a very good _ 45 , but I know I"m lucky to have you in my life． You"re the _ 46_ person I"ve ever known．And even when I disagree with you, I never _ 47 _you love me and want what"s best for me．Thanks for not 48 up me.”
When her mom read the note, she cried and hugged Sandy 49 but said little．
The next morning, Sandy found a 50 on her mirror: "Dearest Sandy, I want you to know being your mother is, by far, the most important thing in my life． 51_ I got your note , I thought I had lost your love and 52 . I felt like such a failure．I intended to 53 it all last night．Your note saved my 54 .”
Be careful not to underestimate(低估) the 55 of expressed appreciation. It won"t always save a life, but it will always make someone"s life better．

Colours are really made by reflected(反射)light. We see colour because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn‘t reflect any light, it is black.
Some of the light is reflected and some is taken in(吸收)and turned into(变成)heat(热能).The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured(深色的)clothes are warmer in the sun than light-coloured clothes.
小题1:When something reflects light, we can_______.
| A．see its colour | B．see its heat | C．not see its colour | D．see nothing |
| A．dark-clolured clothes | B．red-coloured clothes |
