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.

size of our office.

此句中掌握的重点是when的用法，现分述如下：
