Mobile phone use among children has become a problem for the school this year. Several children have got mobile phones as Christmas gifts, and more students want them.
Mary Bluett, an official, said mobile phone use is a distraction(分心)to students during school hours and it also gives teachers so much trouble in their classrooms. Teachers were also saying that sometimes students might use phone messages to cheat during exams.
She said some schools had tried to ban mobile phones. Some parents felt unhappy because they couldn’t get in touch with their children.
Many teachers said students should not have mobile phones at school, but if there was a good reason, they could leave their phones at school offices. They also said there were many reasons why the students should not have mobile phones at school: they were easy to lose and were a distraction from studies.
Many people say that they understand why parents would want their children to have phones, but they think schools should let the students know when they can use their mobile phones.

Last Friday, at least 5 people were killed by lightning in Nepal(尼泊尔).
Lightning strikes are the second most common cause of deaths during natural disasters in the US. The first is floods. Around 400 people nationwide are struck by lightning each year, and of those, 73 people die. There are more people killed by lightning than by tornadoes and hurricanes.
Because lightning kills only one or two people at a time, its danger does not receive as much attention as other disasters.
So to raise awareness, the US has made June 22-28 National Lightning Safety Week. It aims to warn the public of the dangers of lightning and provide safety tips during thunderstorms.
"If you hear thunder, you are in danger of lightning," said Rocky Lopes, a disaster educator at the American Red Cross.
"Thunder means that lightning is close enough to hit you at any minute, so you should move indoors immediately and stay there until after the storm has ended. The single most important thing to remember is to seek a hiding place," Lopes said.
Summer is the high time for lightning storms, so when lightning strikes across the sky, remember these safety tips:
Stop working, fishing, swimming or playing in open fields.
If you can count less than ten seconds between a thunder and a lightning flash, take cover inside the nearest building.
Do not stand under a tree.
Get off bicycles or motorcycles.
Crouch down(蹲下)if there is no hiding place.
Avoid open spaces, wire fences, metal objects and electrical objects such as hair driers.
小题1: The popular opinion about being struck by lightening is that ______.
A.there’s a greater chance for being killed by lightening than any other natural disaster |
B.it is the most dangerous among all the natural disasters |
C.the chance for a person to be struck by lightening is very small |
D.it is impossible for people to be killed by lightening |
A.18% | B.50% | C.30% | D.73% |
A.just stand by your bicycles and motorcycles |
B.quickly find a place to go inside |
C.count ten seconds between a thunder and a lightening |
D.don’t have a hair drier in your hand |
A.There are more people killed by tornadoes and hurricanes than by lightening in US each year. |
B.There are on average 5 persons killed by lightening in Nepal each day. |
C.The death rate of being stuck by lightening is much higher than by other natural disasters. |
D.The National Lightening Safety Week is made to warn the public against![]() |
NEW DELHI----Just a few years ago, Mala was a typical middle-class Indian housewife. She cooked, cleaned and looked after her two small children.
Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive and her mother-in-law took her children away from her, saying they would get the disease. “When friends dropped for a visit, she would introduce me, saying, ‘She is my son’s widow. She has AIDS,’” said Mala. AIDS is now described as “explosive(炸药)” around the world. A study of a hospital in the port city of Durban in South Africa, where the world’s biggest and Africa’s second AIDS conference opened last Sunday, found that almost half the beds in medical wards (病房) were occupied by AIDS patients.
South Africa has one of the world’s fastest growing HIV infections, with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus than Africa, where the disease has killed about 12 million people.
AIDS is now threatening to surround many of Asia’s poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of infected people, because of the population base.
In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 860,000 people (the actual number may be a little larger), mainly drug users, live with HIV/AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates that the number hit by AIDS in Asia will climb about eight million over the next five years from about six million.
In many Asian countries, the battle against HIV is a social and cultural one against public discussion of sexual health put a nationwide media campaign into action to limit the speed of HIV through unsafe sex. Brenton Wong, an official for Singapore’s Action for AIDS, says the actual HIV incidence in the city state of 3.9 million people is at least eight times higher than official data. “Shame and deny is still very, very common so people are afraid to get tested and many times won’t even tell their families if they test positive,” said Wong.
小题1:We can conclude from the underlined sentence in the last paragraph that ______.
A.The official data always tell lies and cheat people to hide![]() |
B.3.9 million people in Singapore suffered from AIDS. |
C.Singapore has a population of 3.9 million |
D.The number of people infected with HIV is at least eight times larger than that of the AIDS patients in Singapore. |
A.4.3 million | B.6 million | C.8 million | D.3.7 million |
A.![]() | B.unsafe sex | C.love | D.drugs |
A.The battle against Aids in many Asian countries is against their culture and social customs. |
B.Though the HIV infection in Asia develops with low speed, the infected number is still quite large compared to other continents. |
C.India has the second largest number of HIV infected people. |
D.Aids might affect the poverty-stricken countries more severely. |

While China may be the world’s biggest toy maker, many of the best are exported. Department stores here do not have enough toys of high quality. It is said that the demand for educational toys is low.
A US company, Baby Care, is trying to change that with a new way to sell toys in China.
Baby Care works basically together with doctors in Beijing hospitals. People who join the company’s "mother club" can get lectures and newsletters on baby and child development at no extra cost, if they agree to spend 18 dollars a month on the company’s educational toys and child-care books.
"We want to build a seven year relationship with those people," said Matthew J. Estes, Baby Care’s president. "It starts during pregnancy (孕期), when the anxiety and needs are highest." Baby Care works on a one-to-one basis. Doctors, nurses, and teachers paid by Baby Care advise parents and explain toys that are designed for children at each stage of development to age six.
Baby Care opened its first store in China last June in a shopping center in central Beijing and another near Beijing Zoo. It plans to have 80 stores in China within six years.
It is a new model for China and develops a market in young children’s education and health that no other companies are in.

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 p

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 die 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 die skin and the internal organs,.
