Read the following article and select the best answer. Article: The sun was just coming up when I headed out to work last May at 6 a.m. Not quite dark but dark enough to need my headlights. I turned onto one of the lonely rural country roads. Maybe it was because I was listening to the radio, maybe it was because I was already thinking about some projects at work, that I didn't spot the dark object on the road until I was too late. I ran over it and felt the back left tire pull, and then sink. I stopped and got out of the car. No mystery here---- my back left tyre was cut like a loaf of bread. Back 50 yards was a piece of sharp iron I had run over. I had never changed a tyre. I looked up the road. Not a car in either direction. The nearest service station was miles away. I threw up my hands. Then I remembered---- my cell phone! I powered it up before realizing, I didn't know who to call. Wouldn't you know it, I spotted a car coming from the opposite direction. The driver slowed as he approached. I guessed he could see I was in trouble. He stopped his car, got out and immediately saw the trouble. "Madam, would you like me to change that tyre for you?" he asked. The man couldn't have been more friendly. I was frightened out there and he put me completely at ease. "There," he said, after putting on the spare, "you are all set to go." "Good thing for me that you were driving this way," I told him, as I climbed back into my car. "Funny you should say that," he said. "Just like you, I was heading to work, but my job is in the opposite direction. I made a wrong turn at some point. I don't know what I was thinking." Question: What did the man do when he saw the writer? - He stopped and laughed at her. - He walked over to frighten her. - He helped her without hesitation. - He drove away in the opposite direction.
He helped her without hesitation.

Read the following article and select the best answer. Article: The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world. These were the goals set out by the Shanghai Water Authority. With the city's population expected to increase only slightly and the economy to boom by 2020, Chen Yin, an official in the water authority, said Shanghai's water consumption will not increase from its present amount. Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, "Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve." He said water saving will help keep the sustainable development of China's economy. Saving one cubic meter of water means saving the city's infrastructure costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology. "The aim is to arouse public awareness of the seriousness of water shortages," Chen said. "The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water." Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city's drinkable water, is nearing exhaustion. The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water. Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used. At present, the city has 600,000 family toilets, each using 13 liters of water per flush. These are to be renovated to use only 9 liters of water per flush. The authority is renovating the first 200 toilets for households - at a cost of Yuan each. In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation. Another task the city is engaged in is the treatment of sewage to improve the water... Question: We can infer from the passage that _ . - not everyone today in Shanghai is aware of water shortage - citizens today in Shanghai drink the best quality of water in the world - the boom of economy will need a larger amount of water in the future - all the family toilets will be renovated to save water within 3 years
not everyone today in Shanghai is aware of water shortage
