真题演练

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.

参考答案及解析:
1. being -> been

2. their -> its
此处物主代词指food,所以要用单数形式的所有格its。

3. relative -> relatively
修饰形容词(此处是过去分词形式)要用副词,所以要把relative改为relatively。

4. good -> bad / poor
从逻辑上说,应该是收成不好(bad / poor harvest)是带来粮食危机(food crisis) 的原因之一,所以应该把good改为poor或者bad。

5. as -> /
此处是表示“即使”的意思,所以应该去掉as,即even if。

6. politics -> political
Politics是名词,修饰名词reasons要用形容词.

7. by -> for
for instance“例如”是固定搭配。

8. double -> doubled
have (more than) doubled

9. few -> fewer
And连接两个对称结构,此处均比较级:fewer stems and more seeds。

10. crop -> crops
crop意为“庄稼,作物”时是可数名词,要用复数形式。
