China has lately been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some 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, 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.

Linda was kind of late. Linda, 25, had a lot to do at work, plus visitors on the way: her parents were coming in for Thanksgiving from her hometown. But as she hurried down the subway stairs, she started to feel uncomfortably warm. By the time she got to the platform, Linda felt weak and tired — maybe it hadn’t been a good idea to give blood the night before, she thought. She rested herself against a post close to the tracks.

Several yards away, Frank, 43, and his girlfriend, Jennifer, found a spot close to where the front of the train would stop. They were deep in discussion about a house they were thinking of buying.

But when he heard the scream, followed by someone yelling, “Oh, my God, she fell in！”Frank didn’t hesitate. He jumped down to the tracks and ran some 40 feet toward the body lying on the rails. “No ! Not you ! ”his girlfriend screamed after him.

She was right to be alarmed. By the time Frank reached Linda, he could feel the tracks shaking and see the light coming. The train was about 20 seconds from the station.

It was hard to lift her. She was just out. But he managed to raise her the four feet to the platform so that bystanders could hold her by the arms and drag her away from the edge. That was where Linda briefly regained consciousness, felt herself being pulled along the ground, and saw someone else holding her purse.

Linda thought she’d been robbed. A woman held her hand and a man gave his shirt to help stop the blood pouring from her head. And she tried to talk but she couldn’t, and that was when she realized how much pain she was in.

Police and fire officials soon arrived, and Frank told the story to an officer. Jennifer said her boyfriend was calm on their 40minute train ride downtown—just as he had been seconds after the rescue, which made her think about her reaction at the time. “I saw the train coming and I was thinking he was going to die, ” she explained.

A. By helping her rise to her feet.                       B. By lifting her to the platform.   

C. By pulling her along the ground.                     D. By dragging her away from the edge.

58. When did Linda become conscious again?
