The Red Cross is an international organization which cares for people who are in need of help. A man in a Paris hospital who needs blood, a woman in Mexico who was injured in an earthquake, and a family in India that lost their home in a storm may all be aided by the Red Cross.

The Red Cross exists in almost every country around the world. The world Red Cross organizations are sometimes called the Red Crescent, the Red Mogen Daid, the Sun, and the Red Lion. All of these agencies share a common goal of trying to help people in need.

The idea of forming an organization to help the sick and wounded during a war started with Jean Henri Dunant. In 1859, he observed how people were suffering on a battlefield in Italy. He wanted to help all the wounded people regardless of which side they were fighting for. The most important result of his work was an international treaty called the Geneva Convention(日内瓦协定). It protects prisoners of war, the sick and wounded, and other citizens during a war.

The American Red Cross was set up by Clara Barton in 1881. Today the Red Cross in the United States provides a number of services for the public, such as helping people in need, teaching first aid and providing blood.

A good title for this passage is .

A. People in Need of Help B. Safety and Protection

C. The International Red Cross D. Forming an Organization to Help People

The word “aided ” in the first paragraph means .

A. needed B. helped C. caught D. protected

The author really tries to make the reader see that this organization .

A. costs very little money B. works in many nations

C. teaches first aid if necessary D. is called the Sun

We may draw a conclusion (下结论)that during a war.

A. the Red Cross only protects the wounded

B. the Red Cross only helps prisoners of war

C. the Red Cross only helps citizens

D. the Red Cross helps all the people in need no matter which side they are fighting for

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increase the risk.

Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma

Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.

But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.

The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

The underlined word “flaws” in the 2nd paragraph most probably means ______.

A. evidence B. facts C. faults D. failures

People with fair skin and freckles .

A. seldom use sunscreen B. are more in danger of skin cancer

C. can be free from the harm of the sun D. often expose themselves to the sun

We can learn from the passage that ______.

A. sunscreen users get skin cancer more often

B. the volunteers have proved the effect of sunscreen

C. the new study was based on the experiences of volunteers

D. the number of skin cancer patients is increasing in America

Which of the following can be the title for this passage?

A. Sunscreen to Prevent Skin Cancer B. Sunscreen to Increase Skin Cancer

C. Skin Cancer Caused by Sunscreen D. Skin Cancer Caused by Freckles

CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
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 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 that supports both the skin and the internal organs.
66. The best title for this passage would be_______.
A. The danger of smoking B. A survey of smokers
C. Quit smoking for health D. Smoking causes skin aging
67. how wrinkled each person's skin doesn’t relate to_______.
A. the number of cigarettes a person smokes
B. the kind and characteristics of skin
C. how long a person smokes
D. how long skin is under sunlight
68. It can be inferred from the study _______.
A. smoking won’t make skin protected from the sun age
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
69. From the passage smoking results in skin aging mainly because_____.
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
70. The main purpose of the passage is to ______.
A. inform people about the result of the study
B. advise people to how to protect skin
C. warn people not to smoke again.
D. introduce a new way of avoid skin aging

An experimental solar-powered plane landed safely Thursday after completing its first 24-hour test flight, proving that the aircraft can collect enough energy from the sun during the day to stay aloft(在空中) all night.

Pilot Andre Borschberg eased the Solar Impulse onto the runway at Payerne airfield about 30 miles southwest of the Swiss capital Bern at exactly 9 a.m. (3 a.m. EDT) Thursday. Helpers rushed to stabilize the pioneering plane as it touched down, ensuring that its massive 207-foot wingspan didn't scrape the ground and topple(倾倒) the craft.

The record feat(壮举) completes seven years of planning and brings the Swiss-led project one step closer to its goal of circling the globe using only energy from the sun. ‘We achieved more than we wanted. Everybody is extremely happy,’ Borschberg told reporters after landing.

Previous flights included a brief ‘flea hop’ and a longer airborne test earlier this year, but this week's attempt was described as a ‘milestone’ by the team. The team said it had now demonstrated that the single-seat plane can theoretically stay in the air indefinitely, recharging its depleted batteries using 12,000 solar cells and nothing but the rays of the sun during the day. But while the team said this proves that emissions-free air travel is possible, it doesn't see solar technology replacing conventional jet propulsion(喷气推进) any time soon. Instead, the project's overarching purpose is to test and promote new energy-efficient technologies.

Project co-founder Bertrand Piccard, himself a record-breaking balloonist, said many people had been skeptical that renewable energy could ever be used to take a man into the air and keep him there. ‘It’s a matter of time that people come to believe and understand about renewable energies,’Piccard said, adding that the flight was proof that new technologies can help break society's dependence on fossil fuels.

The team will now set its sights on an Atlantic crossing, before attempting a round-the-world flight in 2013, making only five stops along the way. ‘It's absolutely not time to relax,’ said Piccard.
