【诊断指导】
习惯上不使用被动语态的几种情况
1)不能用于被动语态的动词和词组，常为结束性动词或状态动词。

如：add up to, appear, arrive, become, belong to, be to blame(受谴责), break out, consist of, come true, die, escape, exist, fail, fall, happen, last, occur, remain, rise, stay, succeed, take place
The news quickly spread in the country.这个消息在国内很快传开了。

2)下列动词的主动语态表示被动意义，而且常与well, quite, easily, badly等副词连用。

如：lock（锁）; wash（洗）; sell（卖）; read（读）; wear（穿）; blame（责备）; ride（乘坐）; write(写); draw(画); cut （削）; end（结束）; shut（关）;
My pen writes smoothly.我的钢笔写起来很流畅。

The cloth looks good and washes well. 那种布看起来不错，还很耐洗。

3)不定式在easy, difficult, hard, heavy, light, fit, comfortable, dangerous, impossible等形容词之后作状语时，常用主动形式表示被动意义
His speech is n’t easy to understand. 他的演讲不易理解。

The coffee is better to taste. 这咖啡味苦。

4)在need, want, require等动词后，用动名词的主动形式表示被动意义
The bike wants/needs repairing. (=The bike needs to be repaired.) 这辆自行车需要修理。

5)在形容词worth后面用动名词的主动形式表被动意义，不可接不定式。

但可用be worthy to be done 或be worthy of being done形式亦可表达同样的意思。

如：
The book is worth reading again.
=The book is worthy to be read again.
=The book is worthy of being read again. 这本书值得再读。

解题注意点
1) 时态并不是“源于”语法规则的，而是说话人用来表达一定意思的。

我们不可以说某个句子“只能用这个时态”而“不能用那个时态”。

一个句子应该用什么时态只能取决于它需要表达的意思，以及它所处的语言环境，绝不可脱离实际应用，一味死记硬背语法条条。

2) 要认真研读试题的题干，搜索尽可能多的“时间参照信息”，尤其是动词冗余信息中的时间信息。
