句子一：

What else can be said about a bizarre animal that, among other eccentricities, eats mud, feeds almost continuously day and night but can live without eating for long periods, and can be poisonous but is considered supremely edible by gourmets?

这种古怪的动物，有着种种怪诞的习性和特点，包括吃淤泥，几乎日夜不间断的进食但长时间不吃东西也能活下来；身体具有毒性却被美食家推崇为大补的食物。除了这些之外，关于它我们还能再谈点什么呢？

句子二：

Erosion can occur if soil is dry, which is a likely effect if it contains inadequate amounts of carbon.

如果土壤中的碳元素含量低，土壤就可能会干燥，这样的话就会造成侵蚀。（土壤干燥是因为含碳量不足的结果，而土壤易受侵蚀又是土壤干燥造成的）

句子三：

Several parents spoke of requests for work being ignored or refused by the school.

好几位家长都提到了要求去医院工作但不被校方理睬或被拒绝的事情。（言外之意就是：好几位家长都曾提出要去医院工作的要求，但校方根本不予理睬或者直接拒绝）requests for work being ignored or refused by the school是动名词复合结构做speak of宾语，其中requests for work是动名词的逻辑主语，动名词短语用的是被动语态。

单词选择题：

1.

Sea cucumbers come in a variety of colors, ranging from black to reddish brown ___ sand color and nearly white.

A. to B. of C. and D. with

这个肯定是选A。range from 表示包括的一个范围，from A to B to C的用法很常见的。

比如这句：The web would be a repository for all human knowledge, a global marketplace for products and ideas, a forum for anything that required interaction, from delicate international diplomacy to working out complex differential equations to buying office supplies--and it would be entirely free of regulation and control!

2. 

If you carefully build a toy house with an erect set, it will still stand no matter ___ you shake the table.

A. how B. how strongly C. how much D. how violently 

这道题我会选择D。

因为strongly通常表达的是情感或者气味的强烈、浓烈程度；much表示程度的高低或者量的多少；只有violently表示力量的大小。

3. prevent sb. from doing sth. from可以省略不写是吗？

prevent sb （from）doing sth，其中from可以省略。
