We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don't keep reducing emissions(排放) of carbon dioxide (CO2 ) and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment. For one month we recorded our personal emissions of CO2. We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭) produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man is Changing the Climate and What it Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica. "To stay below that point, we need to reduce CO2 emissions by 80 percent," he said.

Good advice, I thought. I'd opened our bedroom windows to let in the wind. We'd gotten so used to keeping our air-conditioning going around the clock. I'd almost forgotten the windows even opened. We should not let this happen again. It's time for us to change our habits if necessary.

1.Why did the author and his wife try a new diet?

A. To take special kinds of food.

B. To respond to climate change.

C. To lose weight.

D. To improve their health.

2.The underlined words "tipping points" most probably refer to ________.

A. freezing points B. burning points

C. melting points D. boiling points

3.It can be inferred from the passage that ________.

A. it is necessary to keep the air-conditioning on all the time

B. it seems possible for every household to cut emissions of CO2

C. the average US household produces about 3,000 pounds of CO2 a month

D. the average European household produces about 1,000 pounds of CO2 a month

The word "OK" is the most frequently spoken all-purpose expression on the planet — and it's turning 176 years old on March 23, 2015. The term was born during a 19th-century abbreviation(縮寫(xiě)) craze and went on to international fame with its own hand gesture.

Last year, Henry Nass, a 64-year-old retired English teacher, a New Yorker, had spent the last few weeks handing out cards championing "Global OK Day" in advance of the coming anniversary.

"No matter where people are from they use the word 'OK,' but they don't know where it comes from," says Nass. "The problem is because it's just, you know, OK."

The word is OK, perhaps, but its history is definitely better than average. Late etymologist Allen Walker Read traced the two-letter word to 1839, when editors at the Boston Morning Post signed off on articles as “all correct” with a simple word “OK”.

The word made it into print on March 23 of that year, in an article against a rival editor in Providence who had stated wrongly that a band of Bostonians heading to New York would pass through the Rhode Island capital (Providence).

"We said not a word about our team passing 'through the city' of Providence," the Morning Post reported. "O.K. — all correct."

The humor of the Providence-Boston joke has been lost to history — but the word OK took off from there, soon connoting(隱含) agreement, acceptance, averageness, quality or likability.

By 1840, it served as a slogan for President Martin Van Buren's unsuccessful reelection campaign. “Old Kinderhook is OK,” posters stated, a reference to the eighth president's birthplace and his supporters' belief in his satisfactory performance.

1.Why did Henry Nass hand out cards?

A. To let people understand the history of the word “OK”.

B. To call on people to use the word “OK” properly.

C. To appeal to people to celebrate OK Day.

D. To attract people’s attention.

2.What does the author want to convey in Paragraph 4?

A. The history of the word “OK” is known to average people.

B. The history of the word “OK” is unfamiliar to people.

C. People frequently use the word “OK” in history.

D. People are fond of the word “OK” in history.

3.What does the underlined phrase “took off” in Paragraph 7 probably mean?

A. Got off B. Set up

C. Moved off D. Became popular

4.We can learn from the text that Kinderhook is of the eighth American president.

A. the name B. the birthplace

C. the policy D. the belief

It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?

Ocean water is full of salt— and salt water can hold up more weight than fresh water. See for yourself!

You Will Need:

● 3 cups of warm water

● Measuring cup

● Wide-mouthed jar

● Salt

● Spoon

● Raw potato

You Will Do:

1. Pour 1.5 cups of warm water into the jar.

2. Add 1/3 cup of salt.

3. Stir(攪拌) until the salt is completely dissolved.

5. Gently place the potato into the jar. Do not drop it.

What Will Happen:

The potato will sink— but only halfway!

Why?

Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.

You have probably heard of the Mozart effect. It’s the idea that if children or even babies listen to music composed by Mozart, they will become more intelligent. A quick Internet search reveals plenty of products to assist you in the task. Whatever your age there are CDs and books to help you taste the power of Mozart’s music, but when it comes to scientific evidence that it can make you more clever, the picture is more mixed.

The phrase “the Mozart effect” was made up in 1991, but it was a study described two years later in the journal Nature that sparked(激發(fā)) real media and public interest about the idea that listening to classical music somehow improves the brain. It is one of those ideas that sound reasonable. Mozart was undoubtedly a genius himself; his music is complex and there is a hope that if we listen to enough of it, we’ll become more intelligent.

The idea took off, with thousands of parents playing Mozart to their children, and in 1998 Zell Miller, the Governor of the state of Georgia in the US, even asked for money to be set aside in the state budget so that every newborn baby could be sent a CD of classical music. It was not just babies and children who were exposed to Mozart’s music on purpose, even an Italian farmer proudly explained that the cows were played Mozart three times a day to help them to produce better milk.

I’ll leave the debate on the impact on milk yield to farmers, but what about the evidence that listening to Mozart makes people more intelligent? More research was carried out but an analysis of sixteen different studies confirmed that listening to music does lead to a temporary improvement in the ability to handle shapes mentally, but the benefits are short-lived and it doesn’t make us more intelligent.

1.What can we learn from paragraph 1?

A. Mozart composed many musical pieces for children.

B. Children listening to Mozart will be more intelligent.

C. There are few products on the Internet about Mozart’s music.

D. There is little scientific evidence to support Mozart effect.

2.The underlined sentence in paragraph 3 suggests that ________.

A. people were strongly against the idea

B. the idea was accepted by many people

C. Mozart played an important part in people’s life

D. the US government helped promote the idea

3.What is the author’s attitude towards the Mozart effect?

A. Favorable. B. Objective. C. Doubtful. D. Positive.

For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts and rejections with it.

Many weight-conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our mistake is believing that being thin equals being loved, being special, and being cherished. We fantasize (幻想) about what it will be like when we reach the long-awaited goal .We work very hard to realize this dream. Then, at last, we find ourselves there.

But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self-worth, and, of course, love.

It took me a long time to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes towards ourselves, the whole world changes.

1.The passage tries to stress the importance of ____________.

A. body size B. different beauty standards

C. culture difference D. attitudes towards life

2.What does the word “everything” in paragraph 2 mean?

A. The whole world B. All the problems.

C. All the properties.D. The absolute truth.

3.What can be inferred about the author?

A. The author is a Samoan.

B. The author succeeded in losing weight.

C. The author probably got wounded in wars or accidents.

D. The author has been troubled by her/his weight.

4.According to the author , what is the common view of those who have lost some weight first and gained it back later ?

A. They feel optimistic about future plans on weight control.

B. They are indifferent to the regained weight.

C. The feel angry about the regained weight.

D. They think they should give up their future plans on weight control.
