重点·难点·考点及疑点注释

　　短语纵横

　　1during the last three or four hundred years在近三四百年期间

　　用during the last...或in the last...表示“近……时间以来”或“在过去的……期间”，last

　　可换为past，指的是到现在为止的情况或结果，与现在有关，因此，句中谓语动词常用现在完成时。

　　What have you done in the last five days?近五天你干了些什么?

　　During the past month they have done a lot for the poor.

　　在过去的一个月中，他们为穷人做了许多事情。

　　2make a chart制图，绘图

　　He downloaded the information about several countries and made a chart.

　　他下载了几个国家的信息，制了个图表。

　　3start/end with以……开始/结束

　　start意为“开始”，end意为“结束”，with后可跟名词作宾语。

　　His speech started with a song and ended with another song.

　　他的演讲以一首歌开始，以另一首歌结束。

　　4travel path旅行路线

　　此处travel为名词，意思是“旅行”，作定语。path是名词，意为“路线；路程”。

　　My travel path hasn't been decided yet.我的旅游线路还没有定下来。

　　点击句型

　　1be busy doing sth./ with sth.忙于做某事/忙于某事

　　interested in...则是延续性动词短语，表示状态。

　　语法天地

　　人口多少的表达法
