P.72-75Vocabulary

1.Tips:做这类题要知道所给出的单词和题目的意思、区分所给出单词的词性，填空时应注意时态和形式的变化。

1)    threatens

2)    by a small margin

3)    civilize

4)    closed up

5)    wandered

6)    paste

7)    without so much as

8)    sideways

9)    hook up to

10)  universal

11)   chart

12)  Bathed in

详细解释：为什么是bathed in, 而不是being bathed in或 bathing in呢？

先看几个过去分词作状语的例句：1. Seen from the moon, the earth looks green. 从月亮上看时，地球是绿色。2. Satisfied with what he did, the teacher praised him in class. 由于老师对他所做的事情很满意，于是在班上表扬了他。看第1个例句，相当于When the earth is seen from the moon, the earth looks green. 合并后变成Seen from the moon, the earth looks green. 那么教材中的这个题的语法逻辑是：The boundless stretch of corn fields was bathed in glorious（注意被动语态be bathed in）; The boundless stretch of corn fields looked an impressive sight. 这两句合并在一起，就变成了Bathed in glorious sunshine, the boundless stretch of corn fields looked an impressive sight. .

3. Tips: 这样的题是一种同时训练单词语义和写作语法意识的题，难度较大。做此练习不求完全正确，做了练习就有收获。

1)        looked back on; atmosphere; urban life

2)        era; hooked up to the; the electronic

Statistics (1) show that crime in rural (2) areas is now rising faster than in the cities. The era (3) when the countryside stood for (4) safety and security has long gone. No longer is it safe anywhere to go out leaving the door on the latch (5). We all feel vulnerable (6) and seek to strengthen the barriers (7) we use to hold criminals at bay. These can range from old-fashioned bolts and bars to the latest electronic (8) devices. A moment’s reflection (9), however, is enough to bring us face to face with the following puzzle: we may have locked the evils out, but in doing so we have locked ourselves in. This hardly seems a civilized (10) way of life.
