1.make a promise
该动词短语意为“允诺”，其中的promise为名词，与它搭配的词组还有keep one’s promise(守信)等。如：

Promise 也可是动词（vt.& vi.）意为“允诺”，“答应”。
所用动词句型为：
promise to do sth(不定式作宾语)
promise sb. to do sth.（后接双宾语）
promise (sb)that – clause
(that-clause为宾语从句)
如：①He promises me to buy a bike for my birthday gift.
②He promises me that he will buy a bike for my birthday gift.
2.pretend to be a lawyer
该结构中pretend 意为“装扮”，“装假”，后跟不定式或宾语从句 。其中不定式（有时态变化）是试题中的重点考查形式。如：

7.when you show none
此句中掌握的重点是when的用法，现分述如下：
①when在本句中，相当于if,引导条件状语从句，意为“既然”。如：
How can I help them to understand when they won’t listen to
me?
②when意为“当……的时候”，“在……时”，引导时间状语从句。
③when是并列连词（=and then）意为“就在这/那时”，连接两个句子。如：We are about to go to city when it is raining.
8.so young a body
说明：在一个带有形容词的名词词组中，不定冠词a/an 通常放在adj.的前面。但是，如果adj.前有so, too, how,quite时，a/an应放 adj.的后面。其结构是：so/too/how/quite+adj.+a/an +n.。如：

make love to sb .向某人示爱
12.on one condition
该介词短语意为“规定一个条件”。如：
