Nuclear power’s danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can’t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can’t detect them or sense them without a radio receiver. Similarly, we can’t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated（辐射）and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its parents.
Radiation can hurt us. We must know the truth.
1.What is the main idea of the passage?

socialize with others. In Houston, they partnered with the National Tennis Association for a charity event.

Getting old might not be something that's yet to cross your mind. But ageing is unavoidably going to get the better of us one day. And that’s why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.
We all know that regular exercise is good for us. In recent years, although we've been told to aim to walk 10,000 steps a day to remain healthy, other advice to do three quick and energetic 10-minute walks a day is thought to be even more effective. And the latest piece of research might put a spring in your step if you’re someone who walks at a fast pace. That’s because, according to scientists, the speed at which people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing.
Tests on 1,000 people from New Zealand born in the 1970s found that slower walkers tended to show signs of "accelerated ageing". Their lungs, teeth and immune systems were in worse shape than those who walked fester. And what’s worse, the study found not only did slower walkers' bodies age more quickly, their faces looked older and they had smaller brains.
This might be seen as a wake-up call for people with a slower pace who might feel it's time to work out get fitter. But it might be too late; researchers say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.
So, what's the point of knowing that a slower walking pace might mean a smaller brain? Well, researchers say measuring walking speed at a younger age, and understanding what this might mean, could be a way of testing treatments to slow human ageing. This might help us make lifestyle changes while we're still young and healthy. Any steps we can take to prolong a good mental and physical state is a no brainer!
1.Which of the following is considered to be a better choice?
A.Walking 10,000 steps a day. B.Doing three quick and energetic walks a day.
C.Doing irregular exercise every day. D.Frequently doing sports in spring.
2.What can be inferred from the passage?
A.Faster walkers will get fitter, be younger and have bigger brains.
B.People's health condition can be predicted from their walking speed at 45.
C.This study found that slower walkers age more slowly.
D.People who walk faster are more brilliant than slower walkers.
3.What does the underlined word "prolong" in Para.5 mean?
A.give something up B.transfer something at random
C.make something last longer D.put something off
4.What would be the best title?
A.Walking to Stay Young B.Getting Old and Doing Exercise
C.Having a Happy Life D.Slow Walking and Ageing

Most kids grow up learning they cannot draw on the walls. But it might be time to unlearn that training — this summer, a group of culture addicts, artists and community organizers are inviting New Yorkers to write all over the walls of an old house on Governor’s Island.
The project is called Writing On It All, and it’s a participatory writing project and artistic experiment that has happened on Governor’s Island every summer since 2013.
“Most of the participants are people who are just walking by or are on the island for other reasons, or they just kind of happen to be there,” Alexandra Chasin, artistic director of Writing On It All, tells Smithsonian.com.
The 2016 season runs through June 26 and features sessions facilitated by everyone from dancers to domestic workers. Each session has a theme, and participants are given a variety of materials and prompts and asked to cover surfaces with their thoughts and art. This year, the programs range from one that turns the house into a collaborative essay to one that explores the meaning of exile (流放).
Governor’s Island is a national historic landmark district long used for military purposes. Now known as “New York’s shared space for art and play,” the island, which lies between Manhattan and Brooklyn in Upper New York Bay, is closed to cars but open to summer tourists who flock for festivals, picnics, adventures, as well as these “legal graffiti (涂鸦)” sessions.
The notes and art scribbled (涂画) on the walls are an experiment in self-expression. So far, participants have ranged in age from 2 to 85. Though Chasin says the focus of the work is on the activity of writing, rather than the text that ends up getting written, some of the work that comes out of the sessions has stuck with her.
“One of the sessions that moved me the most was state violence on black women and black girls,” says Chasin, explaining that in one room, people wrote down the names of those killed because of it. “People do beautiful work and leave beautiful messages.”
1.What does the project Writing On It All invite people to do?
A.Unlearn their training in drawing.
B.Participate in a state graffiti show.
C.Cover the walls of an old house with graffiti.
D.Exhibit their artistic creations in an old house.
2.What did the project participants do during the 2016 season?
A.They were free to scribble on the walls whatever came to their mind.
B.They expressed their thoughts in graffiti on the theme of each session.
C.They learned the techniques of collaborative writing.
D.They were required to cooperate with other creators.
3.What kind of place is Governor’s Island?
A.It is a historic site that attracts tourists and artists.
B.It is an area now accessible only to tourist vehicles.
C.It is a place in Upper New York Bay formerly used for exiles.
D.It is an open area for tourists to enjoy themselves year round.
4.What does Chasin say about the project?
A.It just focused on the sufferings of black females.
B.It helped expand the influence of graffiti art.
C.It has started the career of many creative artists.
D.It has created some meaningful artistic works.
