The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.
"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich"s team added in their report.
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person"s skin was.
When skin is exposed to sunlight, notably（尤其）the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich"s team wrote.
Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（紧缩）, reducing blood supply to the skin.
Smoking can also damage the connective tissue (组织)that supports both the skin and the internal organs.
小题1:The best title for this passage would be_______.
| A．The danger of smoking | B．Smoking causes skin aging |
| C．Quit smoking for health | D．A survey of smokers |
| A．smoking won’t make skin protected from the sun |
| B．smoking will do damage to skin rather than other organs |
| C．smokers over 65 usually won’t worry about their skin |
| D．the age of smokers is not connected with the result of the test |
| A．it will lower blood supply to skin | B．it can make you feel tired |
| C．it can make skin come off | D．it can make blood run faster |
| A．inform people about the result of the study |
| B．advise people how to protect skin |
| C．warn people not to smoke again |
| D．introduce a new way of avoiding skin aging |

China is conducting a rectification (整顿) within two years. Inspectors will search for all known banned materials in food production. To reduce trading barriers, China will raise the ratio of adopting international standards in the food industry to 55 percent from today’s 23 percent. “Safety is the first consideration for anything entering people’s mouth followed by its nutritious value,” said Hao Yu, secretary-general of the National Food Industry Standardization Technique Committee. He added the usage of food addictives (添加剂) will be a major field for consideration in setting the new standards. On-the-spot checks during the past two years have shown the abuse (滥用) or misuse of addictives in food production and processing has become the biggest threat to food safety. In one case, talcum (滑石粉) powder was found in flour products, which is outlawed according to national food standards.
“At present there are no methods or standards to test the content of talcum powder in flour,” said Shang Yan’e, an official with the national watchdog on grain and oil inspections. Under the guidelines, all banned addictives will be recorded as inspections increase, Relevant departments have allocated (分配) funds to conduct risk evaluations on current food addictives to fix the limits of their usage. China will adopt international advanced techniques and standards so as to find out the harmful materials in food within a shortest period.
小题1:China will raise the ratio of adopting international standards in the food industry by _____.
| A．55% | B．32% | C．23% | D．78% |
| A．Safety | B．Value | C．Nutrition | D．Addictives |
| A．Addictives are dangerous to people’s health. |
| B．Chinese food will be as safe as foreign food. |
| C．New food safety standards are to be fixed. |
| D．Food safety is a major concern in present China. |
Hungry elephants cause big problems for farmers and villagers in some parts of Kenya when they are searching for food. Two years ago the Kenyan wildlife service had to unwillingly shoot five elephants who continued to destroy crops.
In order to prevent such bad activities, the Elephants charity put a mobile phone SIM card on a huge bull elephant called Kimani. The conservationists(自然保护者) then set up a virtual(虚拟的) fence. Each time Kimani came near the fence, a text message was sent to farmers. So far he’s been stopped from going into the danger area fifteen times.
The project seems to be working successfully as Kimani hasn’t come near a farm for four months. A similar system has now been put into operation in another part of the country.
One of the biggest benefits of the project is that elephants seem to learn from one another, which can help a whole group change their habits.
The elephants can also be tracked using Google Earth software. This is also helping the protectors know where to use their resources to protect the animals well.
小题1:Elephants often cause problems in Kenya, because ______.
| A．they are attacked | B．they are angry |
| C．they are sad | D．they are hungry |
| A．The protector. | B．The writer. |
| C．The elephant. | D．The conservationist. |
| A．the text messages are of little help to the wildlife protectors |
| B．the project has worked out to be a great success in Kenya |
| C．a mobile phone SIM card has been put in all the elephants |
| D．the project has been introduced to all parts of the country |

Their guidance teacher was their adviser, consulting with them when the group encountered difficulties. Though they sought advice from English，math and science teachers， they were responsible for monitoring one another’s work and giving one another feedback. There were no grades, but at the end of the term，the students wrote evaluations of their classmates.
The students also designed their own course. In addition to some regular courses，they each took on an ‘individual project’，learning to play the piano or to cook，writing a novel or making a video about domestic(国内的) violence. At the end of the term，they performed their new skills in front of the entire school. The last part of their self - designed course was to do a ‘collective project’ that had social significance. Because they felt the whole experience had been so life – changing，they ended up making a film showing how other students could start and run their own schools.
The project was a success. After returning to their traditional study，the students have high motivation and are doing well. One student who had failed all of his previous math courses spent three weeks teaching the others about probability. The lesson learned here is that if students are given the opportunity to take control or contribute significantly to their own learning they will become more accomplished，more engaged and more knowledgeable.
The students in the project are remarkable because they demonstrate the kinds of learning and personal growth that are possible when teenagers feel ownership of their high school experience，learn things that matter to them and learn together.
小题1:Which of the following statements is TRUE?
| A．Some students might drop out of high school. |
| B．The teachers monitored the students’ homework. |
| C．The students themselves solved all their problems. |

| B．tended to escape from the whole society |
| C．were unwilling to share their experiences |
| D．focused on self-study and working together |
| A．the traditional study is better than the project |
| B．all the students had failed their math courses |
| C．the students have freedom to design their lessons |
| D．the project was mainly concerned with math courses |
| A．they are unusually talented |
| B．they have better backgrounds |
| C．they have supportive teachers |
| D．they are owners of their education |
| A．Structure the kids’ days to the minute |
| B．Let kids rule their own school within a school |
| C．Offer students few opportunities to do anything |
| D．Provide traditional education to the students |
Once upon a time—July 20, 1969, to be specific – two men got out of their little spaceship and wandered around on the moon for a while. Ten more men walked on the moon over the next three and a half years. The end.
Unfortunately, not quite. A fair number of Americans think that this whole business of moon landings really is a fairy tale. They believe that the landings were a big hoax (骗局) staged in the Mojave Desert, to convince everyone that U.S. technology was the “best” in the whole wide world.
Which is the harder thing to do: Send men to the moon or make believe we did? The fact is that the physics behind sending people to the moon is simple. You can do it with computers whose entire memory capacities can now fit on chips the size of postage stamps and that cost about as much as, well, a postage stamp. I know you can because we did.
However, last fall NASA considered spending $15,000 on a public-relations campaign to convince the unimpressed that Americans had in fact gone to the moon. That idea was mostly a reaction to a Fox television program, first aired in February 2001, that claimed to expose the hoax. The show’s creator is a publicity hound (猎狗) who has lived up to the name in more ways than one by hounding Buzz Aldrin, the second man on the moon. Mr. X (as I will call him, thereby denying him the joyous sight of his name in print) recently followed Buzz Aldrin around and called him “a thief, liar and coward” until the 72-year-old astronaut finally lost it and hit the 37-year-old Mr. X in the face.
Anyway, NASA’s publicity campaign began to slow down. The nonbelievers took the campaign as NASA’s effort to hide something while the believers said that $15,000 to convince people that the world was round — I mean, that we had gone to the moon — was simply a waste of money. (Actually, the $15,000 was supposed to pay for an article by James E. Oberg, an astronomy writer who, with Aldrin, has contributed to Scientific American.)
If NASA’s not paying Oberg, perhaps it could put the money to good use by hiring two big guys to drag Neil Armstrong out of the house. Armstrong is an extremely private man, but he is also the first man on the moon, so maybe he has a duty to be a bit more outspoken about the experience. Or NASA could just buy Aldrin a commemorate plaque (纪念匾) for his recent touch on the face of Mr. X.
小题1:We can learn from Paragraphs 2 and 3 that some Americans believe _______.
| A．moon landings were invented |
| B．U.S. technology was the best |
| C．moon landing ended successfully |
| D．the Mojave Desert was the launching base |
| A．NASA’s publicity campaign. | B．The Fox television program. |
| C．Buzz Aldrin. | D．James E. Oberg. |
| A．proof to hide the truth |
| B．stupid and unnecessary |
| C．needed to convince the non-believers |
| D．important to develop space technology |
| A．NASA should not bother with the non-believers. |
| B．Armstrong was a very private and determined person. |
| C．Armstrong should be as outspoken as Buzz Aldrin. |
| D．NASA should send more astronauts to outer space. |
