Early artists drawing these animals accomplished a monumental and difficult task．They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex．
Unfortunately，the paintings have been exposed to the destructive action of water and temperature changes，which easily wear the images away．Because the Lascaux caves have many entrances，air movement has also damaged the images inside．
Although they are not out in the open air, where natural light would have destroyed them long ago，many of the images have been destroyed and are barely recognizable．To prevent further damage，the site was closed to tourists in 1963，23 years after it was discovered．

举一反三
Elsewhere，heavy tropical(热带的)storms often result in floods that ruin crops especially in Thailand and Malaysia．This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them．If there is a typhoon or tsunami，thousands of lives are lost too．This happened in Indonesia and Phuket in Thailand in 2004 and It serves to remind us of how Mother Nature can cause great damage．
Weather patterns in general have changed dramatically in recent years．Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise．This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level．It is believed that human activities have caused Mother Nature to show her extreme anger，so it is now important that we really work together to cut down on harmful activities，for example，illegal logging(伐木)or irresponsible forest-burning to clear land for farming．

“The great advantage of a Smartphone is that it provides so many tools in a single，readily available，relatively inexpensive package，”said Qia Wang，a doctoral student who led the development of the software．“For example，on the battlefield，a soldier needs a rangefinder，compass，GPS and other tools to get information before calling in an air strike．With our software，the soldier can have all those instruments in one device that can be purchased off the shelf．When that soldier returns from War，she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video．”
Wang and his colleagues developed their software to locate and track：
Targets of known size—when the size of the target is known．a single image is enough to pinpoint the target’s location．
Targets of unknown size—If the exact size of a target is unknown，the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target，the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently，our software is limited by the physical abilities of smartphone hardware，but the devices are improving rapidly，”Wang said．“We expect that improvements in GPS accuracy，battery life and camera resolution will allow our software to make even more accurate observations．”

Blue/Purple
Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants (抗氧化剂) that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight.
A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer.
Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc.
Green
We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer.
Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene （胡萝卜素）. Diets high in those above are associated with lowered blood pressure."
Foods that contain the green color are: broccoli, cabbage, cucumbers, etc.
Red
Lycopene (番茄红素) in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks.
Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce."
Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc.
Orange
The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A.
"Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the color orange are: Carrots, mangoes, sweet potatoes, pumpkins, etc.
小题1:The passage tries to tell us that ______.
| A．colors mean a lot to people and their health |
| B．foods of different colors will have different benefits |
| C．eating foods with a color must prevent diseases |
| D．what people should eat in their daily lives |
| A．lowering blood pressure | B．improving eyesight |

RTC.A. an organization which advises the aviation (航空 )industry, has suggested that all airlines ban such devices from being used during "critical" stages of flight particularly take- off and landing. Some experts have gone further, calling for a total ban during all flights .Cur- rently , rules on using these devices are left up to individual airlines. And although some air- lines prevent passengers from using such equipment during take-off and landing, most are un- willing to carry out a total ban, given that many passengers want to work during flight.
The difficulty is predicting how electromagnetic fields might affect an aircraft"s computers. Experts know that portable devices send out radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory. they have no way of knowing whether the interference might be. dangerous or not.
The fact that aircraft may be fragile to interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who can "t hear the instructions to turn off his radio because the music"s too loud.
小题1:What is said about the over 100 aircraft incidents in the past 16 years?
| A．They may have been caused by the damage to-the radio systems. |
| B．They may have taken place during take-off and landing. |
| C．They were proved to have been caused by the passengers portable computers. |
| D．They were suspected to have resulted from electromagnetic interference. |
| A．Because it is extremely dangerous to conduct such research on an airplane. |
| B．Because it remains a mystery what wavelengths are liable to be interfered with. |
| C．Because research scientists have not been able to produce the same effects in labs. |
| D．Because experts lack adequate equipment to do such research. |
| A．they don"t believe there is such a danger as radio interference |
| B．the harmful effect of electromagnetic interference is yet to be proved |
| C．most passengers refused to take a plane ,which bans the use of radio and cassette players |
| D．they have other effective safety measures to fall back on |
| A．a new rule for all airlines |
| B．the disadvantages of electronic devices |
| C．a possible cause of aircraft incidents |
| D．effective safety measures for air flight |
That might seem an extraordinary act of selflessness for someone turning 20. But there’s increasing evidence that commitment to community service is becoming much more ordinary to today’s young adults.
“Young adults are doing more volunteer service than in any point in history,’’ said Scott Seider, an assistant professor of education at Boston University who studies the civic development of young adults.
At Harvard, the Winthrop Street Homeless Shelter is one of 86 social service programs associated with the Phillips Brooks House Association, which is a student-run nonprofit organization. Students can work with deaf children, bring pets to nursing homes, and prepare Chinese students to become US citizens, and so on.
Volunteerism develops well outside of colleges, too. Applications to AmeriCorps have risen to a very high level, jumping from 91,399 in 2008 to 258,829 in 2010. City Year, which puts young people in high-poverty schools as tutors and mentors for at-risk students, has had a 140 percent increase in applications since its 2007-2008 service year. Citizen Schools, which uses volunteers to work with students in middle schools, has had a 28 percent jump in applicants between 2008 and 2009.
“Most of my friends know it’s their duty to give back before they settle down,’’ said Samantha Wolf, a 23-year-old Boston University graduate serving with City Year in a Mattapan school.
City Year corps member Antonio Gutierrez, 22, graduated last year from Union College in Schenectady, N.Y., and is applying for admission to law schools, but this year he is tutoring and mentoring students at the Blackstone Elementary School in the South End.
“I grew up in similar circumstances,’’ said Gutierrez, who said he was a weak student until enrichment programs changed his academic trajectory (轨迹). Raised by a single mother in low-income housing across the street from City Year’s South End Headquarters, he used to watch the red-jacketed corps members come and go, and decided to become one someday.
小题1:We learn from what Scott Seider says in Paragraph 3 that young people today .
| A．study harder than before |
| B．do more volunteering than ever before |
| C．don’t care much about others |
| D．like to find jobs in their communities |
| A．It helps to find jobs for college students. |
| B．It offers shelters to the homeless people. |
| C．It helps to build schools for poor students. |
| D．It engages young people to teach at high-poverty schools. |
| A．He wants to give back as a volunteer. |
| B．He has always been an excellent student. |
| C．He never expected to become a volunteer. |
| D．He now works as a teacher. |
