“have/has sb. ever+动词的过去分词”用于询问某人过去的经历，ever表示“曾经”，用以加强语气。
例：Has she ever been to France 她曾经去过法国吗？
Have you ever climbed the Great Wall
你曾经登过长城吗？

afford用法比较丰富，后面可以接名词、
代词和动词不定式。
例：We cannot afford the trip.
我们承担不起旅行的费用。
We cannot afford to go on a holiday this
year. 我们今年没钱度假。
4. I've stopped trying now.
注意: stop doing sth. 表示“停止正在做的

做的事去做另一件事”。试比较：
She stopped singing.
她停止了歌唱。
She stopped to sing.
她停下来去唱歌了。
5. You can make it up.
make up表示“创造，编造”。
例： He made up an interesting story and told it
to his friends.他编了个有趣的故事讲给他的朋友

make up还有“组成，构成”的意思。
例：The three paragraphs make up a passage.这
三个段落构成了一篇文章。(共16张PPT)
