Cell phone use and texting are increasingly common, especially among teens. And that could be a problem. Texting affects learning and performing on test, a new study finds. So a Montana teen, Colin decided to test that.

They asked 47 classmates to take part in a two-part experiment. The goal was to test how well these students understood written material. Each one had to read a paragraph or two about a certain topic, then answer questions about it.

In the first part, the participants had 15 minutes to understand and then answer questions about six readings. Throughout this test, they met no distractions.

During a new set of readings, the brothers sent messages to the participants’ cell phones every 90 seconds. In each message, there were questions that required a reply.

Participants should have scored better on the second test because it was easier. In fact, they scored worse when distracted by messages. Only a few students scored as well when replying to messages as they did when undistracted. But importantly, nobody performed better during the texting part.

The brothers presented details of their findings at the Intel International Science and Engineering Fair. Boys and girls scored equally poorly while texting, the brothers noticed. Older participants didn’t do any better than younger ones. And it didn’t matter if a student thought he was good at multitasking. On average, the brothers found that even students who were confident of their abilities did just as poorly while texting. Surprisingly, even though the students remembered less of what they read while texting, most of them answered questions in messages perfectly.

“Our teachers are very happy to see these results,” says Coler. The teens’ new data strongly support their teachers’ opinion that texting while studying is a serious distraction.

1. What did Colter and Colin want to test?

A. Cell phone use and texting are more common.

B. Teens should avoid cell phone use and texting.

C. Texting affects students’ performance on test.

D. The effect of texting differs from person to person.

2.What can we learn from the two-part experiment?

A. The written material in the two parts was the same.

B. Participants in part 2 received more than one message.

C. The time of the test in two parts was the same.

D. All the participants were distracted by messages.

3.The brothers’ findings were related to participants’ ________.

A. reading performance B. quality

C. writing ability D. reading speed

4. From the results of the experiment, we can find _________.

A. boys were better at multitasking than girls

B. the easier the tests were, the more mistakes were made

C. nobody did good jobs in the two-part experiment

D. some students’ test results were not affected by texting

5.What’s Colter’s teachers’ attitude toward the results?

The oldest and most common source(来源) of renewable energy known to man, biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----biomass promises to play a continuing role in providing power and heat for millions of people around the world.

According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide(二氧化碳), because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun’s energy. In this way, biomass serves as a sort of natural battery(电池) for storing the sun’s energy. As long as biomass is produced continuously ----with only as much grown as is used--- the “battery” lasts forever.

According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008----although the numbers aren’t all in yet----wind power probably took over first place because of the rapid development of wind farms across the country.

Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner’s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.

1.Why is biomass considered as “ a sort of natural battery”?

A. It burns merely plant matter.

B. It keeps producing electricity.

C. It stores the energy from the sun.

D. It produces zero carbon dioxide.

2.We learn from the text that in 2008 ______.

A. Wind power would be the leader of renewable energy.

B. there was a rapid growth of electricity production

C. biomass might become the main energy source

D. 0.5~0.9 of power supply came from biomass

3.Why does the author encourage power plants to use biomass?

A. To prevent the waste of energy.

B. To increase production safety.

C. To reduce pollution.

D. To save money.

4.Where does the text probably come from?

A. A research plan. B. A science magazine

C. A book review. D. A business report.
