Two things I really believe in --- saving money and saving the planet, and it’s even better when I can do something that accomplishes both at the same time. Rainwater harvesting is just such a thing. In the near future, rainwater harvesting will be as common as twelve-year-old girls carrying cell phones.

Many countries already rely heavily on rainwater. Every building in these countries collects the rainwater from its roof and stores it for later use. However, America is just slightly slow to take action.

There are many ways to harvest rainwater and most of them are easy and inexpensive. For example, use rain barrels（桶）to collect the water that would run off your roof. You’d be surprised at how fast a fifty-gallon（加侖）barrel will be filled with free, usable water. New building construction offers some good ways to gather rainwater, and the cost of set-up is usually made up by reduced usage very quickly. Rainwater can be conveyed by roof pipes into underground containers, where a pump can draw water up as needed.

The rainwater can even be treated to make it drinkable. If that rainwater were not collected, but allowed to run over your lawn（草坪）, into the street and eventually to a storm water treatment facility, it would pick up all sorts of pollutants on its journey --- chemical compositions and agricultural poisons from the grass, motor oil, waste water and such from the roads, and who knows what else. That is to say, the shorter distance it covers the more drinkable it will be.

Depending on where you live, the rainwater may be piped to a treatment plant or it may run in natural channels to allow nature to remove the pollutants. Either way, the treatment of rainwater is high priced. If you reduce the amount of rainwater run-off from your home or office, you reduce the need for treatment.

Water is rapidly becoming one of our most precious resources and it is not as abundant as you may think. In the year 2015, the United States used generally 479 billion gallons of fresh water per day.

Your friends' lives may look more exciting than yours on Facebook，but new research shows that is because they are faking(偽造)it.

A recent survey has found around two?thirds of people on social media post images(圖像) to their personal information to make their lives seem more adventurous.And more than three quarters of those asked said they judged their peers(同齡人)based on what they saw on their Instagram，Snapchat or Facebook pages.

The British survey，by smartphone maker HTC，found that，in order to make our own pages and lives appear more exciting，six percent also said they had borrowed items to include in the images in order to pass them off as their own. More than half of those surveyed said they posted images of items and places purely to show off，causing_jealousy among friends and family.

Behavioural psychologist Hemmings said the trend was unsurprising due to the rise of social media.“We're living in a world of instant communication.”she said.“Fashion and style used to live and die in magazines；now people are in search of authentic （真實(shí)的），peer?to?peer recommendations as well，making social media an equal power house to magazines and newspapers.”

“With images being shared in an instant we desire to know what our friends are wearing，or what super stars are buying, as soon as they have got them.” Such is the influence of social media sites like Instagram,76 percent of those asked also said seeing items on social media influences them to buy them，with men more likely to take style advice and buy what they see.

1.How do some people make their lives appear more exciting?

A. By buying pictures.

B. By posting images.

C. By making up stories.

D. By risking their lives.

2.What does the word “jealousy” in Paragraph 3 mean?

Scientists have proved that sleeping and learning go hand in hand. Even a short nap can boost our memory and sharpen our thinking. But the relationship goes deeper than that.

“The brain is not passive while you sleep,” scientist Anat Arzi said. “It’s quite active. You can do many things while you are asleep.”

Arzi and her coworkers didn’t try to teach the sleeping volunteers any complex information, like new words or facts. Instead, the scientists taught volunteers to make new connections between smells and sounds.

When we smell something good, like a flower, we take deep breaths. When we smell something bad, we take short breaths. Arzi and her co-workers based their experiment on these reactions.

Once the volunteers fell asleep in the lab, the scientists went to work. They gave them a whiff of something pleasant and meanwhile played a particular musical note. They didn’t wake up, but they heard—and sniffed(吸氣) deeply. Then the scientists gave the volunteers a whiff of something terrible and played a different musical note. Again, the volunteers heard and smelled—a short snort this time—but didn’t wake up. The researchers repeated the experiment.

After just four repetitions, volunteers made a connection between the musical notes and their paired smells. When the scientists played the musical tone that went with good smells, the sleepers breathed deeply. And when the scientists played the musical tone that went with bad smells, the sleepers breathed briefly—despite there being no bad smell.

The next day, the volunteers woke up with the sound-smell connection. They breathed deeply when hearing one tone and cut their breaths short when hearing the other, which must have been unusual for them. Imagine walking down the street and taking a deep breath upon hearing a particular sound!

1.In the study, the volunteers were taught _______.

A. to become active during sleep

B. to tell the difference between smells

C. to learn new words and scientific facts

D. to make sound-smell connections

2.How did the volunteers react when smelling something nice and hearing musical notes?

A. They took a deep breath.

B. They had a wonderful dream.

C. They woke up at once.

D. They took a short breath.

3.When the volunteers woke up the next day, they_______.

A. learned how to play to musical tones

B. forgot what happened during their sleep

C. continued with the sound-smell connection

D. changed their reaction when hearing the sound

4.The passage mainly tells us _______.

A. special smells and sounds can improve our memory

B. our brain can actually learn something new during sleep

C. the volunteers will always hear similar sounds on the street

D. our brain can tell the difference between smells during sleep
