In most towns today, you can see teenagers standing over electronic machines with flashing lights, shooting at spaceships from other planets and dropping bombs on strange monsters(恶魔). The machines have names like Space Warrior, Dark Invader and so on. It used to be believed that damage was done only to those strange visitors from outer space, but now it seems that they are striking back.
Many teenagers like electronic games so much that they can't stop playing. They spend hours tightly holding the joystick controls and constantly pressing buttons marked "fire". They develop pains on their fingers because of the constant pressure. They play and play that the pains have no chance to cure properly. The rapid wrist movement required to guide the spaceship across the screen causes another problem: the muscles of the wrist and arm become so inflamed and swollen(充血红肿) that they press against the bones. This condition is what doctors now call "Space Warrior's Wrist". Other strange aches and pains are also likely to affect the elbows and shoulders.
Another even more alarming problem is shown by the case of a 17-year-old girl which was recently reported in the British Medical Journal. She had been playing various kinds of electronic games for more than two hours a day. Her father repaired games and machines and she could use the cassettes and systems in his workshop as often as she liked. One day, after playing a game called Dark Invader, she lost consciousness(知觉) and fell to the floor. Doctors who examined her found she was suffering from an unusual illness caused by lights flashing at a particular frequency.
Electronic games are found very popular with __________.
A. people living in towns B. students studying in high schools
C. girls working in their father's workshops D. young people age about 13-19
"Space Warrior's Wrist" is caused by __________.

China has recently been faced with serious issues of product safety. Some cases have brought attention internationally to the increased use of imported ingredients to make food and medicine.
In Panama, medicine made with a poisonous chemical killed or sickened more than one hundred people. A Chinese company had identified it as diethylamide glycol （ [化]乙二醇）, a low – cost substitute commonly used in automobile antifreeze（防冻剂）.
Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine（三聚氰胺）, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.

查看习题详情和答案>>In 1977, a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way. The author was Agatha Christie, one of the most successful writers of detective stories in the world.
In June 1977, a baby girl became seriously ill in Qatar, near Saudi Arabia. Doctors were unable to find out the cause of her illness with confidence, so she was sent to Hammersmith Hospital in London. She was then only semi-conscious (半清醒状态) and on the "Dangerously Ill" list. A team of doctors hurried to examine the baby only to discover that they, too, were confused by the very unusual symptoms (症状). While they were discussing the baby's case, a nurse asked to speak to them.
"Excuse me," said Nurse Marsha Maitlan, "but I think the baby is suffering from thallium poisoning. (铊中毒)"
"What makes you think that?" Dr. Brown asked. "Thallium poisoning is extremely rare."
"A few days ago, I was reading a novel called A Pale Horse by Agatha Christie," Nurse Maitlan explained. "In the book, somebody uses thallium poison, and all the symptoms are described. They're exactly the same as the baby's."
"You're very thoughtful and you may be right," another doctor said. "We'll carry out some tests and find out whether it's thallium or not."
Tests showed that the baby had indeed been poisoned by thallium, a rare metallic substance used in making special glass. Once they knew the cause of the illness, the doctors were able to give the baby the correct treatment. She soon recovered and was sent back to Qatar. Later it was reported that the poison might have come from an insecticide (杀虫剂) used in Qatar.

A. a doctor in Qatar B. Nurse Maitlan
C. Dr. Brown D. Agatha Christie
The baby was sent to London because _____.
