Lie in bed, by an open window, and listen…
“No air conditioning? How can you sleep?” a friend asks, horrified. I tell her my family has decided to shut the air conditioner off and reduce our electric bill. On this first night of our cost-cutting plan, it’s only 85 degrees. We’re going to suffer, but the three kids complain anyway.
They have grown up in 72-degree comfort, protected from the world outside.
“It’s too hot to sleep,” my 13-year-old daughter complains. “I’m about to die from this heat,” her brother complains down the hall. “Just try it tonight,” I tell them. In truth I’m too tired to turn for long. My face is sweaty, but I lie quietly listening to the cricket choirs outside that remind me of childhood.
The neighbor’s dog howls. Probably a passing squirrel. It’s been years since I took the time to really listen to the night.
I think about grandma, who lived to 92 and still helped with my mom’s gardening until just a few weeks before she died. And then, I’m back there at her house in the summer heat of my childhood. I move my pillow to the foot of grandma’s bed and turn my face toward the open window. I turn the pillow, hunting for the cooler side.
Grandma saw me turn over and over. “If you just watch for the breeze(清风),” she said, “you’ll cool off and fall asleep.” I stare at the filmy white curtain, willing it to move. Lying still, waiting, I suddenly notice the life outside the window. The bug chorus. Neighbors, porch(门廊)-sitting late, speak in unclear words that calm me.
“Mom, did you hear that?” my seven-year-old son cries, “I think it was an owl(猫头鹰)family.”
“Probably,” I tell him, “just keep listening…”
Without the working air conditioner, the house is peaceful, and the natural night noises seem close enough to touch. I hope I’m awake tonight when the first breeze comes in.

As any parent with an iPhone or an iPod Touch knows, mobile apps (手机软件) can be an engaging and entertaining experience for kids. Now, a new study of PBS Kids suggests that the experience can be an educational one as well.

The study, which was administered by PBS under a grant from the Department of Education, first tested the vocabulary level of a group of 90 Title 1 school children, aged 3 to 7. Then, the children were each given two weeks with an iPod Touch loaded with the Martha Speaks Dog Party app created by PBS Kids.

The study monitored how the children used the iPod, during what hours, and in what context. On average, the study found that kids played with the iPod Touch for a total of 5 hours across the two weeks, with half that time spent playing the Martha Speaks app. At the end of the two week trial, the children were given another vocabulary test, which revealed an increase in vocabulary acquisition by as much as 31 per cent.

The study findings are particularly useful as smart phones and mobile devices have become increasingly popular among families and parents are faced with a proliferation of mobile apps designed for kids. According to a recent Nielsen study, smart phone usage is 12% higher in households with children than other households.

“Mobile apps can be a great learning tool in the hands of children,” said Lesli Rotenberg, SVP, Children’s Media, PBS. “This research is important in helping to better understand and guide the development of new apps that improve the value of children’s screen time with significant educational outcomes.”

So what does it all mean? Well, at the very least it will help parents get over that guilty feeling when they hand over their iPhone or iPod Touch for a little peace and quiet. At best, it provides more evidence that mobile devices and apps do indeed have educational value and could be an important part of the child-learning process for many years to come.

1.What Lesli Rotenberg said in the fifth paragraph suggests that       .

A. he has a positive attitude towards mobile apps

B. he thinks children should never use smart phones

C. he is doubtful about mobile apps designed for children

D. he thinks parents should be careful with mobile apps for children

2.The underlined sentence in the last paragraph implies that       .

A. parents will feel more comfortable giving kids iPhone or iPod Touch

B. parents will know what kind of mobile phones are suitable for kids

C. parents will know what children do with mobile phones

D. parents can watch over their children now and then

3.What would be the best title of the text?

A. The popularity of smart phones among kids 

B. The entertaining function of smart phones

C. Smart phones make kids learn more.             

D. It’s too early for kids to use smart phones

Astronomers have captured(捕获) the first direct image of a planet being born.

Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.

The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.

Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.

Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.

Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.

Planets can change orbits(轨道) after forming, so it’s difficult to answer such questions by studying older planets.

“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.

Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮强过) them. Kraus and Ireland used two techniques to overcome this problem.

One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.

The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.

1.The research on younger planets helps scientists _____________.

A. study why planets change orbits after forming

B. understand how planets move around their stars

C. answer questions about the age of stars and planets

D. know the relationship between planets and their stars

2.Why are young planets like LkCa 15b hard to discover?

A. Their stars are brighter than them..      B. They are very far from the earth.

C. They are generally too small.           D. They rarely form.

3.According to the text, Kraus and Ireland _____________.

A. have been working in the same university

B. observed the planet on a volcano in Hawaii

C. used two new methods in the observation

D. cut holes in the mirrors when observing

4.Which of the following would be the best title for the text?

A. Youngest planet seen as it’s forming.

B. Planet 450 light years away discovered.

C. World’s first direct image of a planet taken.

D. New technique helps discover young planets.
