With petroleum reserve(石油儲量)decreasing, the search is on to replace gas with a cleaner, greener alternative. Though much eco-talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae(藻類).
Algae, like corn, soybeans, and other crops, grow via photosynthesis(光合作用)and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U.S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable(適于耕種的) land and fresh water that will be in short supply as the world’s population balloons.
“If you replaced all the diesel(柴油)in the U.S. with soy biodiesel, it would take half the land mass of the U.S. to grow those soybeans,” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif-based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require only l5, 000 square miles, which is a few thousand miles larger than Maryland (12,407 squaree miles), the 42nd state in land area.
Another advantages: Because algae can be grown just about anywhere in a closed space, they’re being tested at several power plants across the nation as a carbon absorber. Smokestack emissions(煙囪排放物)can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.
Although processing technology for algae fuel—also known as “oilgae” in some environmentalist circles —is improving, it’s still years away from reaching your local gas pump. “It’s just a question of cost, because no large-scale facilities have been built yet,” Caspari says.
【小題1】The underlined word “yield” in Paragraph 2 can be replaced by “_______”.

A.controlB.requireC.produceD.grow
【小題2】Compared with corn and soybeans, algae_____.
A.may pollute water and soilB.can grow in poor conditions
C.provide much less energyD.need more special care
【小題3】According to Paragraph 3, one of the advantages of algae fuel is that ____.
A.it can be used more widelyB.it is easier to produce
C.it needs much less landD.it costs much less money
【小題4】Which of the following might be the best title for the text?
A.Environmental ProtectionB.Biofuels from Corn and Soybeans
C.The False Hope of BiofuelsD.A Promising Oil Alternative

Everyone has done experiments in high school laboratories, but have you ever thought about designing a satellite to explore space?

On Nov. 19, a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record-setting. 28 other small ones on a rocket were sent from a NASA center in Virginia, CNN reported. It took the students seven years to build.

The students call their tiny satellite TJ3Sat, which is named after their school. It is just 10x10x12 centimeters and weighs only 0.89 kilograms, according to Orbital Sciences, a company which developed the rocket and supported the students’ project. It can be controlled with a smartphone.

Like most satellites, TJ3Sat can send and receive data. The small spacecraft is equipped with a voice synthesizer (合成器), which can switch text to voice and transmit those sounds back to Earth over radio waves, said Orbital officials. In this case, anyone can give it a try via the project’s website (school website) by submitting (提交) a text. The texts that get approved will be sent to the satellite, changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’ on our ground station and when it is on the other side of the world, in India, someone can hear ‘Go Colonials’over the radio,” the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time. Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs, the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities, Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro, program executive (主管) for small spacecraft technology at NASA, said in a statement. “I think we might be seeing kids saying what they want to do is build a spacecraft. The idea here is that they really can do that.”

1. The underlined word “awed” in the second paragraph is closest in meaning to ___.

A. influenced ??? B. amazed? ??? C. delighted ????? D. inspired

2.Which of the following statements about TJ3Sat is TRUE according to the article?

A.It took a group of students about a decade to build the satellite.

B.Besides TJ3Sat, 28 other small satellites were built by the students.

C.TJ3Sat can receive text messages that the students send into space, which it can change to voice messages and broadcast back to Earth.

D.TJ3Sat is expected to stay in orbit for the next year, sending out messages together with information about its position in space.

3.According to the article, the launch of the satellite _______.

A.is evidence of the advance of spacecraft technology

B.proves that hard-working teenagers can achieve a lot

C.shows the importance of extracurricular activities at school

D.has inspired many people to take an interest in space travel
