　　Energy from the Sun

　　Everyone needs and uses energy. If there were no energy, 46

　　Most of the energy on this planet comes from the sun, but people do not receive that energy directly. It comes from different sources and in different forms.

　　Green plants convert the sun’s energy to food energy that animals and people use for life. The energy from animals has been used for hundreds of years to operate farm equipment and to pull carts, wagons, and other vehicles.

　　The sun’s energy takes water from rivers, lakes, and oceans and 47 When rain or snow falls on the land some of it flows into rivers and streams. This flowing water can be used to 48 Water can also be converted to steam, which produces energy to operate machines.

　　Winds also come from solar energy. Air that has been heated by the sun rises and creates winds. The process of winds has moved ships on the sea, ground grain, and brought water to the earth.

　　There is also solar energy in wood, oil, and coal. These fuels have been 49 People burn them to produce heat and to create power for machines. Oil and coal are used to produce electrical energy, too. And electricity produces light heat, and sound energy. In addition, electric power operates many kinds of equipment, tools, and machines, which make work easier.

　　If you made a list of all the jobs performed by the different kinds of energy, you would fill many pages. The need for power increases every day, and some sources of energy 50 So scientists and technicians are trying to find new ways to produce power.

　　A formed over many centuries from plants.

　　B returns it to the earth in the form of rain or snow.

　　C are being used up very quickly.

　　D there would be no life.

　　E produce mechanical energy and electricity.

　　F are being produced everyday.

　　Improve Computer-research Skills

　　Like many college students, Jose Juarez carries around a pocket-sized computer that lets him watch movies, surf the Internet and text-message his friends.

　　He’s part of "Generation M" - those born after 1985 who 51 up connected to everything from video game to cellphones.

　　"For us, it’s everyday life," said Juarez, 18, a freshman 52 California State University at Sacramento (CSUS).

　　53 , educators are now saying that not all Generation M-ers can synthesize the piles of information they’re accessing.

　　"They’re geeky, but they don’t know what to 54 with their geekdom," said Barbara O’Connor, a Sacramento State communications studies professor who has been involved in a nationwide 55 to improve students’ computer-research skills.

　　In a recent nationwide test to 56 their technological "literacy" - their ability to use the Internet to complete class assignments - only 49 percent correctly evaluated a set of Web sites for objectivity, authority and timeliness. Only 35 per cent could correctly narrow an overly 57 Internet search.

　　About 130 Sacramento State students, including Juarez, participated in the experimental test, 58 to 6,300 college students across the country.

　　The hour-long assessment test is conducted by Educational Testing Service. It is a web-based scavenger hunt (拾荒游戏) 59 simulated Internet search engines and academic databases that spit out purposely misleading information.

　　"They’re very good at 60 in and using the Internet, but don’t always understand what they get back," said Linda Goff, head of instructional services for the CSUS library.

　　"You see an open search box, you type in a few words and you 61 the button," said Goff, who is involved in the testing.

　　"They take at face value 62 shows up at the top of the list as the best stuff." Educators say that these sloppy research skills are troubling.

　　"We look at that as a foundational skill, in the same way we 63 math and English as a foundational skill," said Lorie Roth, assistant vice-chancellor for academic programmes in the CSU system.

　　Measuring how well students can "sort the good 64 the bad" on the Internet has become a higher priority for CSU, Roth said.

　　CSU is considering 65 a mandatory assessment test on technological literacy for all freshmen, much as it has required English and math placement tests since the 1980s.

　　Students in freshman seminars at Sacramento State were asked to take the test early in the semester and were expected to finish another round this week to measure their improvement.
