Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable. Which of the following is true according to the passage？
| A．Genetic limitation will be beneficial for some women |

| B．Cloning should be used in creating life |
| C．Cloning will take away the right to reproduce |
| D．Cloning is acceptable if it is used for cloning organs |

People who multitask all the time may be the worst at doing two things at once, a new research suggests. The findings, based on performances and self-evaluation by about 275 college students, indicate that many people multitask not out of a desire to increase productivity, but because they are easily distracted and can’t focus on one activity. And “those people turn out to be the worst at handling different things,” said David Sanbonmatsu, a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked, how good they thought they were at it, and how sensation-seeking (寻求刺激) or imperative (冲动) they were. They then evaluated the participants’ multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly, the scientists said, most people thought they were better than average at multitasking, and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once. But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test. They also were more likely to admit to sensation-seeking and impulsive behavior, which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity, but because they’re distractible, and they get sucked into things that are not as important.” Sanbonmatsu said.
Adam Gazzaley, a researcher at the University of California, San Francisco, who was not a member of the research group, said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest, however, why the sensation-seeker who multitask the most may enjoy risky distracted driving. “People who are multitasking are generally less sensitive to risky situations.” said Paul Atchley, another researcher not in the group. “This may partly explain why people go in for these situations even though they’re dangerous.”The research led by Sanbonmatsu indicates that people who multitask __________.
| A．seek high productivity constantly |
| B．prefer handling different things when getting bored |
| C．are more focused when doing many things at a time |
| D．have the poorest results in doing various things at the same time |
When Sanbonmatsu and his colleagues conducted their research, they __________.
| A．assessed the multitasking ability of the students |
| B．evaluated the academic achievements of the students |
| C．analyzed the effects of the participants’ tricky mental tasks |
| D．measured the changes of the students’ understanding ability |
According to Sanbonmatsu, people multitask because of their __________.
| A．limited power in calculation |
| B．interests in doing things differently |
| C．inability to concentrate on one task |
| D．impulsive desire to try new things |
From the last paragraph, we can learn that multitaskers usually __________.
| A．drive very skillfully |
| B．go in for different tasks |
| C．fail to react quickly to potential dangers |
| D．refuse to explain the reasons for their behavior |

In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an interactional festival of music, dance and theatre in Edinburgh. The idea was to reunite Europe after the Second World War.
At the same time, the “Fringe” appeared as a challenge to the official festival. Eight theatre groups turned up uninvited in 1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.
Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little-known writers of plays in small church halls to the people of Edinburgh.
Today the “Fringe”, once less recognized, has far outgrown the festival with around 1,500 performances of theatre, music and dance on every one of the 21 days it lasts. And yet as early as 1959, with only 19 theatre groups performing, some said it was getting too big.
A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.What was the purpose of Edinburgh Festival at the beginning?

The Healthy Habits Survey (调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
Finding: A full 33% of seniors brush their teeth only once a day.
Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2. How many times did you wash your hands or bathe yesterday?
Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.
Step: We touch our faces around 3,000 times a day-often inviting germs (病菌) to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.
3. How often do you think about fighting germs?
Finding: Seniors are not fighting germs as well as they should.

It's 30 that you think it wise for yourself to know your place and stay away from worldly trouble wearing a mask of cowardice, behind 31 the flow of sap in your life will be retarded (妨碍).
To get a thorough understanding of oneself 32 doing oneself a favor when it's needed. In time of anger, do yourself a favor by giving vent (发泄) to it in a quiet place so that you won't be hurt by its flames; in time of 33 , do yourself a favor by sharing it with your friends so as to change a gloomy mood into a cheerful one; in time of tiredness, do yourself a favor by getting a good sleep or taking some tonic. Show yourself loving 34 about your health and daily life. Unless you know perfectly well when and how to do yourself a favor, you won't be confident and ready enough to resist the attack of illness.
To get a thorough understanding of oneself is to get a full control of ones life. Then one will 35 one's life full of color and flavor.
