黃金29篇的第14篇一個問題 - 英檢

第五小題

先容po個那段落的節錄
The first wells were drilled into the Ogallala during the drought years of

the early 1930’s. The ensuing rapid expansion of irrigation agriculture,

especially from the 1950’s onward, transformed the economy of the region.

More than 100,000 wells now tap the Ogallala. Modern irrigation devices, each

capable of spraying 4.5 million liters of water a day, have produced a

landscape dominated by geometric patterns of circular green islands of crops.

Ogallala water has enabled the High Plains region to supply significant

amounts of the cotton, sorghum, wheat, and corn grown in the United States.

In addition, 40 percent of American grain-fed beef cattle are fattened here.

這題問說

why does the author provide the information that 40 percent of American
cattle are fattened in the High Plains?

2.To indicate that not all economic activity in the High Plains is dependent on
irrigation

3.To provide another example of how water from the Ogallala has transformed the
economy of the High Plains

答案是3.

可是我選了2.

我的理由是
3.的文意是說

"提供另外一個關於Ogallala的水 變成High Plains的經濟一部分"

所以3的選項被我刪了

相對來講 我選的2就合理多了阿 提完農業 再提牧業

各位看官 你說我是不是很有理阿 有人可以幫我解答一下嗎
------------------------------------------------------

再問一個句子的文法 從cambridge閱讀Test3中 第一大題節錄的

Such heat would destroy any life-forms lucky enough to have survived to
this point.

我想問的是 從life-forms 後面 lucky開始 就是受詞補語(OC)嗎？
因為我一直看不懂這句的文法
為什麼life-forms後面 不加 which is
----------------------------------------------------------

最後一個

我想要取暖一下

我做黃金29篇從第10篇開始都會錯4-6題耶

我爬文看人家都說黃金29超簡單

那是代表我程度很差嗎

閱讀到底要怎麼進步.....教教我
