In 2002, the Beijing Municipal government led the nation in issuing an order banning electric bicycles from January 1, 2006. Since then a number of local governments have followed this.  

In May, the Legislature of Zhuhai in South China’s Guangdong Province became the first law-making body in the country to pass a regulation to keep electric bicycles off the roads.  

They claim environmental disadvantage and concerns over public safety justify their ban.  

Local government officials and law makers have argued their leading concern is the threat of pollution from spent lead-acid batteries. The relatively high speed of electric bicycles --- faster than most common bikes at about 20 kilometers per hour --- is just too dangerous in the eyes of some policy-makers.  

They also mention interference with automobiles, common bikes and passers-by that results in accidents or slowed traffic.  

But none of these arguments justify the ban.  

In the first place, it should be made clear that while operating, the battery driving an electric bike sends out almost no polluting gas. They are much cleaner than cars. If the batteries, which can be used for one or two years, are thrown away without proper treatment or recycling, environmental damage is highly likely.  

It is required that electric bike producers and store sellers sign recycling contracts to ensure consumers can sell used batteries back to producers. In practice, some small producers neglect their recycling responsibility, causing concern for environmental pollution.  

It is clear the authorities can solve the problem through strengthening management. Although it will require some extra efforts from the government, it does not go beyond government officials’ call of duty.  

Regarding the speed, there are technical standards governing the production of electric bikes. According to the standards, the designed speed should be limited to a maximum of 20 kilometers per hour. This is slower than the top speed of some mountain bikes.  

To cater to the consumer desire for higher speed, some manufacturers have made it easy to remove speed-limiting devices after purchase, which is potentially very dangerous.  

To make the bicycles safer, local governments should draft regulations specifying severe punishments for rule-breakers. The black sheep should be picked up and punished, but violations by a small number of manufacturers or riders should not be an excuse to spoil the fun for everyone.

China Daily Oct. 11, 2008 The Ministry of Health has called for more awareness from the public on the mental health of the young, as part of efforts to mark the World Mental Health Day which fell on Friday.  

More than 15 percent of Chinese youths have been found with mental problems, and about 30 million young people under 17 are suffering from depression, the Shanghai-based Wenhui Daily reported. The World Health Organization estimates that before 2020, the rate of children with mental problems will increase to 50 percent, and mental problem will become a major factor behind deaths and illness in the young worldwide.  

Deng Xiaohong, the spokesperson for the Beijing Municipal Health Bureau, said rapid social changes is one of the reasons behind the rising number of youngsters with psychological problems. If these mental diseases are not treated on time, science of crimes, drug-taking and other dangerous behaviors are expected to rise. Experts said mental diseases could be caused by many factors, such as the inability to handle interpersonal relations well, unstable emotions and pressures from an overload of studies. A number of expects have also said the one-child policy is another reason leading to poor mental health in the young. Children are said to be too “spoiled” and “selfish” in a one-child family.  

It’s reported that schools in many cities are rolling out measures to help students maintain their mental well-being. Yin Jingmiao, a teacher of the Beijing No, 105 Middle School, told China Daily that the school invites psychologists to provide counseling to students three times a month, “Students can be arranged to have 40-mimute counseling sessions, “Yin said. The school also gives lectures on mental health to senior grade students before they take the National College Entrance Exam to help ease any anxiety arising from the tests.”

DNA is a substance that makes up genes. Everything alive has genes. Plants have genes. Animals have genes. You have genes. Genes are the basic units of heredity (遗传). Heredity means all the characteristics you inherit from your parents. You get your genes from your parents. You inherit half of your genes from your mother. You inherit half of your genes from your father. Genes are a kind of code. A tree’s genes tell what shape its leaves will be. A cat’s genes tell what color its fur will be. Your genes tell what color your eyes will be. Your genes tell what color your hair will be. Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells. Everything alive is made up of cells. Chromosomes are in the center, or nucleus, of cells.  

An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants. He experimented with pea plants in the 1860s. One of the things, or traits (特征), Mendel studied was what makes some pea plants tall and some short. He said that the traits must come from units of heredity passed from the parent plants. These units were called genes.  

In the mid-1900s, scientists discovered that genes are made of DNA. In the 1970s, scientists learned how to change DNA with genetic engineering. Scientists also learned that problems with certain genes cause diseases. Muscular dystrophy, cystic fibrosis, and hemophilia are some genetic diseases―diseases caused by problems in genes. Today, scientists are looking for ways to cure genetic diseases by altering genes through a process called gene therapy.
