课时训练江苏人民出版社系列答案In front of the big Shibuya train station in Tokyo, there is a life-size bronze (青铜) statue of a dog. Even though the statue is very small when compared to the huge neon (霓虹灯) signs flashing, it isn’t 21 to find. It has been used as 22 since 1934 and today you will find hundreds of people waiting there for their friends to 23 —just look for the crowds（人群）.
Hachiko, an Akita dog, was born in 1923 and brought to Tokyo in 1924. His owner, Professor Eisaburo Uyeno and he were close friends that cannot be 24 right from the start. Each day Hachiko would go with his owner, a professor at the Imperial University, to Shibuya train station when he left for work. When he came back, the professor would always find the dog 25 waiting for him. 26 , the professor died suddenly at work in 1925 before he could return home.
27 Hachiko was still a young dog, the bond between him and his owner was very strong and he 28 to wait at the station every day. Sometimes, he would stay there for days at a time, though some believe that he kept returning because of the food he was given by street vendors. Over time he became a 29 sight to people going to and from work every day. In 1934, a statue of him was put 30 the station. In 1935, Hachiko died at the place he last saw his friend alive.

Could your cellphone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, powerlines and wi-fi (路由器) could be responsible for a range of illnesses, from rashes to brain tumours.
For example, Camilla Rees, 48, a former investment banker in the US, moved out of her apartment in San Francisco because of the radiation coming from next door. Rees told the Los Angeles Times that when her neighbors moved in and installed a wi-fi router she lost her ability to think clearly. “I would wake up dizzy in the morning. I’d fall to the floor. I had to leave to escape that nightmare,” she said. Since then, she’s been on a campaign against low-level electromagnetic fields, or EMFs（低频电磁场）.
And she’s not alone. Millions of people say they suffer from headaches, depression, nausea and rashes when they’re too close to cellphones or other sources of EMFs.
Although the World Health Organization has officially declared that EMFs seem to pose little threat, governments are still concerned. In fact, last April, the European Parliament called for countries to take steps to reduce exposure to EMFs. The city of San Francisco and the state of Maine are currently considering requiring cancer-warning labels on cellphones.
If these fears are reasonable, then perhaps we should all be worried about the amount of time we spend talking on our phones or plugging into wi-fi hotpots.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the University at Albany, in New York, thinks there’s a greater than 95% chance that power lines can cause childhood leukemia. Also there’s a greater than 90% chance that cellphones can cause brain tumours.
But others believe these concerns are unreasonable paranoia (猜疑). Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cellphones,” said Linet. “We don't have the evidence that there’s much danger.”
Studies so far suggest a weak connection between EMFs and illness — so weak that it might not exist at all. A multinational investigation of cellphones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cellphone industry group.
According to Robert Park, a professor of physics at the University of Maryland in the US, the magnetic waves aren’t nearly powerful enough to break apart DNA, which is how known threats, such as UV rays and X-rays, cause cancer.
Perhaps it’s just psychological. Some experts find that the electro-sensitivity syndrome seems to be similar to chemical sensitivity syndrome, which is a condition that’s considered to be psychological.
Whether EMFs are harmful or not, a break in the countryside, without the cellphone, would probably be good for all of us.
