  Directions:In this section, there is a passage with ten blanks. You are requested to select on word for each black from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the blank is indentified by a letter.

  Please mark the correcsponding letter for each item on Answer Sheet 2 with a single line through the centtre. You may not use any of the words in the bank more than once.

  Questions 47 to 56 are based on the following passage.

  The American patent system, provided for in the Constitution, was designed to encourage the creation and use of new technology.

  A useful patent meant that the inventor could make a lot of money. In exchange for this gover- nmental protection, the government published the patent __53___ , which had to provide enough information so that other people could understand the invention—thus adding to the general__54_technological knowledge. And at the end of the 14 years, anyone could use the invention for__55__.The idea behind the patent system was twofold: it would increase the amount of technology, by providing a way for people to make money out of new ideas, and it would make new technology widely available, by publicizing ideas that might ___56__ be kept as trade secrets.

  B) however J ) yield

Section B

  Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements.

  Passage one(选自CET4,2008.6)

  Questions 57 to 61 are based on the following passage.

  Gobal warming may or may not be the great environmental crisis of the 21 st century, but—regardless of whether it is or isn’t—we won’t do much about it. We will agrue over it and may even, as a nation, make some fairly solemn-sounding commitments to avoid it. But the more dramatic and meaningful these commitments seen, the less likely they are to be observed.

  Al Gore calls global warming an “inconvenient truth”, as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve global warming, and—without major technological breakthroughs we can't do much about it.

  From 2003 to 2050, the world’s population is projected grow from 6.4 billion to 9.1 billion,a 42% increase. If energy use per person and technology remaim the same, total energy use and greenhouse gas emissions (mainly CO2 ) will be 42% higher in 2050. But that’s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world’s poor to their present poverty and freeze everyone else’s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050.

  No government will adopt rigid restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still, politicians want to show they’re “doing something”. Consider the Kyoto protocol (京都议定书). It allowed countries that joined to punish those that didn’t . But it hasn’t reduced CO2 emissions (up about 25% since 1990), and many signatories (签字国) didn’t adopt tough enough policies to hit their 2008―2012 targets.

  The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development progrom might find ways of breaking our dependence on fossil fuels or dealing with it.

  The trouble with the global warming debate is that it has bacome a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering problem, we’re helpless.

  C)It is a problem that can be solved once it is recognized.

  D)It is an area we actually have little knowledge about.
