真題演練
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 ____1____
just around the next corner. The fast-growing population’s
demand for food, they warned, would soon exceed their ____2____
supply, 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 _____3____
spots like present-day Somalia, and occasional years of
good harvests, the world’s food crisis has remained just ____4____
around the corner. Most experts believe this can continue
even as if the population doubles by the mid-21st century, ____5____
although feeding 10 billion people will not be easy for
politics, economic and environmental reasons. Optimists _____6____
point to concrete examples of continued improvements
in yield. In Africa, by instance, improved seed, more _____7____
fertilizer and advanced growing practices have more than
double corn and wheat yields in an experiment. Elsewhere, _____8____
rice experts in the Philippines are producing a plant with few ____9____
stems and more seeds. There is no guarantee that plant
breeders can continue to develop new, higher-yielding
crop, but most researchers see their success to date as reason ____10____
for hope.
參考答案及解析：
1. being -> been
2. their -> its
此處物主代詞指food，所以要用單數(shù)形式的所有格its。
3. relative -> relatively
修飾形容詞（此處是過去分詞形式）要用副詞，所以要把relative改為relatively。
4. good -> bad / poor
從邏輯上說，應該是收成不好（bad / poor harvest）是帶來糧食危機（food crisis） 的原因之一，所以應該把good改為poor或者bad。
5. as -> /
此處是表示“即使”的意思，所以應該去掉as，即even if。
6. politics -> political
Politics是名詞，修飾名詞reasons要用形容詞.
7. by -> for
for instance“例如”是固定搭配。
8. double -> doubled
have (more than) doubled
9. few -> fewer
And連接兩個對稱結構，此處均比較級：fewer stems and more seeds。
10. crop -> crops
crop意為“莊稼，作物”時是可數(shù)名詞，要用復數(shù)形式。
