The deadly earthquake and tsunami (海啸) that struck Japan on March 11 damaged two nuclear power stations. Officials are now working to prevent dangerous radiation from poisoning the air in the area surrounding the Fukushima Daiichi plant. The Japanese government has ordered people living within 12 and a half miles of the plant to evacuate, and asked those living 12 and a half to 20 miles away to stay indoors.
Nuclear power plants create energy using a chemical reaction that produces large amounts of heat. Reactors(反应堆)in Japan have many long, thin rods, called fuel rods(棒), which must be kept cool.
If the reactor’s fuel rods aren’t cooled, the reaction can burn out of control. That’s what happened at the two Japanese plants after the quake caused a power failure and the cooling systems malfunctioned(发生故障). This overheating could cause radiation to escape and sicken many people.
Japan’s 54 nuclear reactors are built to withstand the many small or moderate earthquakes the country faces each year. But Friday’s earthquake was one of the most severe earthquakes ever recorded.
People exposed to unsafe levels of radiation have a higher than normal risk of getting cancer. The Japanese government has been distributing potassium iodide(碘化钾)pills to people in the surrounding areas to protect those who may have come in contact with radiation from the power plant. The pills flood the body with healthy potassium iodide. The potassium iodide works to crowd out “bad” iodine in the body that may have been poisoned by radiation.
On Tuesday morning, 750 workers left the Fukushima Daiichi plant. However, 50 workers stayed behind to use sweater to cool the fuel rods. These dedicated employees are risking their own lives to save many others.
On Thursday, officials used helicopters, fire trucks, and water cannons to spray water on the reactors to cool the fuel rods. But it’s not clear whether these efforts were successful. Officials are now working on a power line to restore electricity to the plant. They hope this will help restart the plant’s cooling system and stop the fuel rods from leaking radiation.The underlined word “evacuate” in Paragraph 1 probably means .

Wildlife faces threats(威胁)from habitat destruction, pollution, and other human actions. Although protecting wildlife may seem too hard at times, even small actions in your own neighborhood can help protect many different animals. Here are some tips on how to protect wildlife through small actions.
1．Create wildlife friendly areas in your backyard.
When trying to make your garden more beautiful, you can choose plants that can provide food and shelter to native wildlife. This will also help cut down on pollution. And bird or bat houses to your yard or garden to attract and shelter these species.
2．Avoid harming the natural ecosystem(生态系统)in your area.
Some plants from other places can kill or harm native plants that provide food and shelter for wildlife.
3．Have a greener lifestyle.
By using less water and fewer fuels, you will be helping to protect the wildlife around you. Take buses or the subway when you can, turn off electric devices when you're not using them, take shorter showers, and keep your room temperature at or below 68 degrees during the winter.
4．Buy products that are wildlife friendly.
Don't buy products that are made from endangered animals. Keep in mind that some endangered animals are killed by traps, catches or hunters who are after other wildlife within the same habitat.
5．Donate money or time to organizations that protect wildlife and their habitats.

If you get a cellphone call, your sleeve(袖子) will soon be able to answer it. If you want to know how far you’ve run, your trousers will be able to tell you. Can’t decide what to wear? Wish your clothes were smart enough to decide for you? A new computer science technology may be able to help your clothing to do just that.
Mark Jones, a computer scientist, says, "We view electronic textiles (电子纺织品) as, sort of, where computing meets the fabric (编织品)."
This high-tech marriage is bringing up the wearable computers, like trousers that can interpret movement and let a computer know your every move.
A loom (织布机) helps make the wires and fabric together. Then special equipment in the fabric can measure the speed. Signals are then sent from the trousers to a computer to show the process.
Tom Martin also says, "E-textiles are a way for us to build wearable computers that look like normal clothing and can fit in fully with the environment."
Researchers also hope wearable computers will help save lives. "We will be able to tell what activity a person is doing. That sort of information is highly valuable when we’re trying to monitor someone with a long-term illness such as heart disease," Jones says. Monitoring your every step is something that clever clothing can do a little easier. Researchers plan on developing more smart clothes to integrate computers into shirts, hats and gloves.What does the underlined word "marriage" refer to in the passage?
| A．The special equipment in the fabric used to measure the speed of our movement. |
| B．The unity（结合）of fabric and computing materials to make smart clothes. |
| C．Wearable computers which fit in with the environment. |
| D．The influence of electronics and computer science technology. |
How will smart clothes be able to know the wearer’s every movement?
| A．There are the wires and fabric together. |
| B．There are signals in the smart clothes. |
| C．The computer built into them will control their every movement. |
| D．The clothing will have special equipment fixed into the fabric. |
The reason that people need smart clothes is that __________.
| A．people are too lazy to decide what to wear |
| B．scientists want to prove their intelligence |
| C．smart clothes can provide information about the wearer’s health |
| D．smart clothes are as cheap as normal clothes |

My grandmother seems to be wrong when she says that good manners will never go out of style.
Several days ago, I tried entering a lift with one of my arms fixed in a bandage(绷带) while carrying a computer bag in the other. Not being fast enough, I was passed by two young people who managed to get into the lift before me. The lift door closed only after I entered. Having already pressed their wanted floor button, the young people waited impatiently for me to press the button for where I was going. If they had decided to help, we could have moved much faster. But they had not. So I did my best and pressed the button with my arm. The two young people looked very angry with me. I was losing heart.
The memory of this incident has stayed with me because it followed shortly after my building’s watchman refused to help me carry a heavy box full of books. His answer was that he could not carry the books a few meters because it was not his job. However, I remembered myself helping people for so many years carrying boxes, shopping bags, or pushing wheelchairs upon the request of a stranger in need or when my conscience(良心) called on me. "Oh, this young generation, they have no manners, ”my grandmother would say. The idea of good manners refers to the considering of other people’s feelings. We need more and more people to have good manners. Good manners should be-come part of our lives. The author believes that ________.

Among the many differences between Western and Chinese cultures, table manners are one of the most noticeable(显著的) differences. Westerners often make mistakes at the table in China or in a Chinese home. In order not to have an embarrassing（尴尬的） experience, here are some things to consider next time you are eating with some Chinese.
Step1:
Keep in mind that food is shared. It is one of the biggest differences between Chinese and Western eating habits. In China a few dishes are placed in the center of a table and shared by all. Also, you should offer thanks when a Chinese host takes food from one of the dishes on the table and places it on your plate. Refusing it would not be polite even if you are full.
Step2:
Respect the chopsticks. The chopsticks are the single most important tool at a Chinese table. Use the chopsticks to grab food and never skewer (叉) it. Also make sure to place your chopsticks over your bowl or plate. Don’t lay them on the table or even worse, stick them into the rice bowl.
Step3:
Use communal(共用的)chopsticks. To take food from the center of the table you should use the communal chopsticks or spoons that are placed there for that purpose. If there are no communal tools, use the other ends of your chopsticks to take food, remembering not to use the other end to put food into your mouth.
Step4:
Respect the elders. Table manners in China place extra respect on elders. At the table, pass food to your elders before taking it for yourself. If someone makes a toast, make sure that when you clink glasses with someone older than you, the rim of your glass is lower than the rim of the elder person.How can you use your chopsticks according to the passage?
| A．Use them to grab your own food. |
| B．Put them on the table. |
| C．Use them to skewer the food. |
| D．Stick them into the rice bowl. |
According to the passage, the following are wrong EXCEPT that ________.
| A．you don’t have to accept the food a Chinese host places on your plate |
| B．a skewer is also a commonly used tool at a Chinese table |
| C．one can offer his own chopsticks for communal use when there aren’t any |
| D．when clinking glasses, the rim of the younger person should be lower than that of the older person |
What is the purpose of writing the passage?
| A．To let the world get a full understanding of China. |
| B．To introduce table manners among different cultures. |
| C．To introduce Chinese table manners to Westerners. |
| D．To introduce how Chinese table manners came into being. |
