Sorry to say,our brains naturally start slowing down at the Cruelty young age of 30.It used to be thought that this couldn’t be helped,but new studies show that people of any age can train their brains to work faster.“Your brain is a learning machine,”saying University of California scientist Dr. Michael Merzenich.Given the right tools,we can train our brains to act like they did when we were younger.All that’s required is the practice designed just for the purpose:a few exercises for the mind.

Merzenich has developed a computer-based training method to speed up the process(过程) in which the brain deals with information (positscience.com).Since much of the data we receive comes through speech,the Brain Fitness Program works with language and hearing to better speed and accuracy(准确性).

Over the course of training,the program starts asking you to distinguish(辨别) sounds (between“dog”and“bog”,for example) at an increasingly faster speed.It’s a bit like tennis instructor,says Merzenich,hitting balls at you—faster and faster to keep you challenged(受到挑战).You may start out slow,but before long you’re pretty quick.

The biggest finding in brain research in the last ten years is that the brain at any age is highly plastic.If you ask your brain to learn,it will learn.And it may even speed up while in the process.

To keep your brain young and plastic you can do one of a million new activities that challenge and excite you:playing table tennis or bridge,doing crossword puzzles,learning a language...“When it comes to preventing ageing,you really do ‘use it or lose it’,”says Barbara Sahakian,professor at Cambridge University.

Dr.Merzenich’s training method mainly depends on ______.

A.speech training

B.computer languages

C.the activities one joins in

D.the information being dealt with

By saying “the brain at any age is highly plastic”,the writer probably means the brain can be ______.

A.used B.mastered

C.developed D.researched

What can we learn from the text?

A.Practice makes a quick mind.

B.Brain research started ten years ago.

C.Dr. Merzenich is a scientist in computer.

D.People believed nothing could stop the brain slowing down.

Which of the following agrees with the writer’s idea?

A.The training methods work better for the old.

B.People should use the brain to stop it from ageing.

C.The training of the brain should start at an early age.

D.It’s necessary to take part in as many activities as possible.

Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.

　　Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.

　　These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.

　　We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

What is the main idea of the first paragraph?

　　A.The air we breathe in is harmful.

B.Chemicals are released in the running water.

C.Chemicals are added to the drinking water.

　　D. The water in everyday use is unsafe.

.In Paragraph 2, the underlined sentence means that .

　　A. homes and offices should be aired often

　　B. any pollution should be taken into consideration

　　C. bathing should be done with caution

　　D.we should prevent any pollution from doing harm to us

What is the purpose of the passage?

　　A.To call on us to guard our water.

　　B.To show us that no place is like home.

　　C.To make us aware of the pollution around us.

　　D.To argue that neither homes nor offices are safe.

In November of 2007, NBC Universal launched its first official Green Week. Throughout the week, NBC Universal presented over 150 hours of environmentally themed content through multiple platforms (平台).

Now, NBC Universal is proud to present Green Week 2012. With a new theme and message of “Green Your Routine”, NBC and NBC.com presents green-themed tips in several of our daytime life, among several other features here on the “Green Your Routine” site.

Fashion & Beauty

Throw a clothes exchange party! Are you dying for that sweater your friend wore the other day? Well, maybe she’ll trade for that old T-shirt you have. Here’s a website that helps you organize an exchange party (www.swapstyle.com), or just plan your own!

Go natural with organic make-up. Applying unnatural products on your skin wasn’t exactly that nature intended. Try switching to a line of organic make-up and cosmetics for a different way to bring out your natural beauty.

Home

Drop a brick in your toilet tank! Literally! According to the EPA, flushing (冲洗) makes up 30 percent of a household’s water use (about three to six gallons per flush). By placing a brick in your toilet tank, you can help to conserve the amount of water used during each flush.

Work

Print smarter. Printing and copying can be one of the most costly operations in any office. To save on ink and paper costs, print double-sided and try to fit more than one page on a sheet. More printing tips can be found here: lifehacker.com

Turn off your computer. Do you leave your computer on over night? If so, you’re using up a good amount of electricity. If you can, try turning off your computer and the power strip it’s connected to. If you can’t, shut off your monitor at least.

Transportation

Organize a car pool (拼车). There are many benefits to carpooling. You save on gas and you get to ride in the HOV lines. Get connected with your neighbors and co-workers to start sharing rides and check out this website for more tips: www.erideshare.com.

Lose the car and get a bike. If you live close to where you work, try taking a bike instead of driving. You’ll keep in shape and save on gas!

Every small step and efforts makes a difference! Be sure to GREEN YOUR ROUTINE!
