  Thomas Malthus published his"Essay on the Principle of Population" almost 200 years ago. Ever since then, forecasters have being warning that worldwide famine was

  S1________

  just around the next corner. The fast-

  growing population's demand for food, they warned, would soon exceed their supply,

  S2________

  leading to widespread food shortages and starvation.

  But in reality, the world's total grain harvest has risen steadily over the years. Except for relative isolated trouble spots like

  S3________

  present-day Somalia, and occasional years of

  good harvests, the world's food crisis has

  S4________

  remained just around the corner. Most experts believe this can continue even as if

  S5________

  the population doubles by the mid-21st

  century, although feeding 10 billion people will not be easy for politics, economic and

  S6________

  environmental reasons. Optimists point to concrete examples of continued improvements in yield. In Africa, by instance,

  S7________

  improved seed, more fertilizer and advanced growing practices have more than double

  S8________

  corn and wheat yields in an experiment. Elsewhere, rice experts in the Philippines are producing a plant with few stems and

  S9________

  more seeds. There is no guarantee that plant

  breeders can continue to develop new, higher-yielding crop,

  S10________

  but most researchers see their success to date as reason for hope.

  答案与解析:

  S1. being→been。本题考查的是现在完成进行时,由have (has) + been + p.p.构成,表示以前到现在动作一直在进行之中。

  S2. their→its。本题考查名词与代词指代不一致的问题。动词exceed后面指代的是前文的单数名词food。 S3. relative→relatively。修饰isolated, 应用副词形式。

  S4. good→bad。根据上下文意思,应将good 改成它的反义词bad。

  S5. 去掉as。因为even if 是一个固定短语,意思是"即使……也"。

  S6. politics→political。本题误把名词用作了形容词。

  S7. by→for。for instance (或 for example "例如")是一个介词的固定搭配。

  S8. double→doubled。动词double表"使……多出一倍;把……增加一倍;增加了一倍",而形容词double表"双的,双人的,双重的"。根据上下文,这里要用动词的过去分词形式,才符合题意。

  S9. few→fewer或less。根据上下文的平行结构可知,本题是考查形容词的比较级形式。

  S10. crop→crops。本题是名词单复数的误用。crop是可数名词,根据上下文可知应该用它的复数形式crops。
