Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving (铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages (短缺)．Drier climates are of course more likely to have droughts (干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there's a lot we can do to lower the number.
You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher (洗碗机) only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
Which of the following is most likely to lead to less groundwater?
| A．Using river water. |
| B．Paving parking lots. |
| C．Throwing batteries away. |
| D．Throwing rubbish into lakes. |
What can be inferred from the text?
| A．It takes a lot of effort to meet our water needs. |
| B．All water shortages are due to human behavior. |
| C．There is much we can do to reduce family size. |
| D．The average family in America makes proper use of water. |
The last paragraph is intended to ________.
| A．show us how to fix leaks at home |
| B．tell us how to run a dishwasher |
| C．suggest what we do to save water at home |
| D．prove what drinking glass is best for us |
The text is mainly about ________.
| A．why paving roads reduces our water |
| B．how human activity affects our water supply |
| C．why droughts occur more in dry climates |
| D．how much we depend on water to live |
I had the meanest mother in the world. While other kids ate candy for breakfast，I had to have cereal，eggs and toast. Others had cokes and candy for lunch，while we had to eat a sandwich. As you can guess，my supper was different than the other kids’. But at least I was not alone in my suffering. My sister and two brothers had the same mean mother as I did.
My mother insisted on knowing where we were at all times. She had to know who our friends were and what we were doing. We had to wear clean clothes every day. Other kids always wore their clothes for days. We reached the height of disgrace because she made our clothes herself，just to save money.
The worst is yet to come. We had to be in bed by 9：00 each night and up at 7：45 the next morning. So while my friends slept，my mother actually had the courage to break Child Labor Law. She made us work. I believed she lay awake all night thinking up mean things to do to us. Through the years，our friends’ report cards had beautiful colors on them, black for passing，red for failing. My mother, however，would merely be content with black marks. None of us was allowed the pleasure of being a dropout.
She forced us to grow up into educated and honest adults. Using this as a background，I’m now trying to bring up my three children. I’m filled with pride when my children think I am mean because now I thank God every day for giving me the meanest mother in the world.From the passage we can learn that the writer’s mother was __________.

London—coffee protects mice from radiation and could get the same way in humans, according to Indian scientists.
Scientist at India’s Bhabha Atomic Research Center discovered that mice injected with caffeine (咖啡因)remained alive after high doses(剂量)of normally lethal radiation.
Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans .
“It does suggest that coffee might have some beneficial effects in protecting against radiation,” he told New Scientist magazine late last month.
George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation(伽玛射线),enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams(毫克)of caffeine per kilogram of body weight were still alive.
On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died.George and his team drew the conclusion from .
| A．the magazine | B．their invention | C．the experiment | D．their experience |
From the news, we know can be protected from radiation.
| A．both mice and humans | B．only mice |
| C．only humans | D．neither humans nor mice |
From paragraph 5, we know 30 percent of the mice died 25 days later. The reason was probably that .
| A．these mice had been given only 80 milligrams of caffeine |
| B．these mice hadn’t been injected with caffeine |
| C．these mice were very big and strong |
| D．these mice hadn’t been given enough caffeine |
Which is the best title of the article?
| A．Human and Mice | B．New Radiation Defense—Coffee |
| C．Deadly Radiation—Gamma Radiation | D．Mice Died of Caffeine |
In paragraph 2,the underlined word “ lethal ”means .
| A．causing death | B．lively | C．exciting | D．rich |
Most lives saved from sinking ferryCao Min couldn’t believe she was experiencing exactly what she had seen years ago in the film “Titanic”.
Cao and her two children from Anhui Province were traveling on board the “Liaoludu 7”on February 22.They were among the first people on the ship who were rescued by lifeboats. Cao’s one-year-old son was the youngest passenger on board.
The “Liaoludu 7”was traveling in the Bohai Straits(渤海海峡)from Lushun in Liaoning Province to the port city of Longkou in Shandong Province. It suddenly lost its power at 2:30 pm and tilted(倾斜)on its side. With 81 people on board, the ferry(渡船)began to sink.
“I was so scared that my legs couldn’t move forward. They kept shaking even when I was asked to jump onto a “ lifeboat.” Cao recalled.
Upon receiving the urgent appeal, China Marine Search and Rescue Center(中国海上搜救中心)immediately informed the State Council(国务院).The center sent eight lifeboats to the sinking ship and asked for help form the Ministry of Agriculture, the Navy and nearby fishing boats.
After more than four hours of fighting against strong winds and freezing ocean water, the passengers were recovered. All but four survived. These four died after spending too long in the freezing waters, according to a spokesperson for the Beijing-based center.

For years and years people have been saying that the railways are dead. “ We can do without railways.” People say…as if motorcars and planes have made the railways unnecessary. We all keep hearing that trains are slow, that they lose money, and that they’re dying .But this is far from the truth: in these days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they are cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, it takes you from the heart of a city into the heart of another. It doesn’t leave you up as a plane does, miles and miles from the city center. It doesn’t hold you up as a car does, in endless traffic jams, and a single train carry goods which a plane or a motorcar could never do.
Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time? And we are only at the beginning, for we have just entered the age of super-fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorcars we can’t use because we have not enough money to buy the oil and planes we can’t fly for the same reason..Some people think the railways are unnecessary for many reasons except that .

The Republic of Vanuatu is an island nation located in the South Pacific Ocean. It was one of the poorest nations in the region. Within the last five years, however, it has become a hot spot for adventure travelers. In 2006 it was voted the happiest place on Earth. The reason is not that Vanuatu are the richest but that Vanuatu has white-sand islands, clear waters, the world’s most accessible live volcano, great diving and food that grows faster than it can be picked.
