1. 【解析】答案是B。stop to do sth.和stop doing sth.意思不同。前者为停下去做另一件事，后者为停止正在做的事。而整个句子的意思为：特丽莎看见了我以后停下来聊了一会儿。所以答案B是正确的。
2. 【解析】答案是C。在主动语态中，我们常用see sb. do/doing sth.的形式。被动语态时就应该为：sb. be seen to do/doing sth.。由于此句中有时间状语this time yesterday所限制，所以答案只能是C。
3.【解析】答案是B。动词tell的用法为：tell sb. to do/not to do sth.。而动词want的用法为want to do sth.。能同时满足这两个条件的只有B。所以答案B是唯一正确的。
4.【解析】答案是B。动名词和不定式可以用作表语。四个被选项中，只有B是不定式的形式。所以答案B是正确的。
5.【解析】答案是B。这句中首先要区分rise（不及物动词）和raise（及物动词）。及物动词一定要跟宾语。其次动词hang的过去式和过去分词有两种不同的形式。hang/hanged/hanged意思为“上吊”；而hang/hung/hung意思为“悬挂”。所以答案B是正确的。
6.【解析】答案是B。everyone意思为每个人；人人，所有的人。所跟的动词要用单数的形式。而用代词或反身代词时看作名词的复数形式，如例句中用了they。所以答案B是正确的。
7.【解析】答案是A。从结构来看，这是一句真实的条件状语从句。我们常在if引导条件句中用一般现在时来代替一般将来时，主句用一般将来时。所以答案A是正确的。
8.【解析】 答案是B。allow这类动词的用法为allow sb. to do sth.为主动语态。根据句意应用被动语态，即sb. be allowed to do sth.的结构。所以答案B是正确的。
9.【解析】 答案是C。此句中有两个提示语。他们分别是look和just now。一般情况下，提示语look出现时大都用现在进行时；just now出现时大都用一般过去时。但是根据上下文的意思，此句的意思为：麦克已经在黑板上画了一只鹭，是刚才画的。所以答案C是正确的。
10.【解析】 答案是B。形容词generous的意思为大方的、慷慨的。它可以用来表示主语的特征，用于It+ be+形容词+of+名词或代词+不定式的结构中。而在It+ be+形容词+ for+名词或代词+不定式的结构中，for+名词或代词作不定式的逻辑主语，表示不定式所表示动作的特征。所以四个被选项中只有答案B是正确的。 |
