Step2Languagepoints

1.Ourownplanet,theEarth,isbecomingmoreandmorecrowdedandpollutedbecauseoftherapidincreaseinpopulation.

我们自己的星球,地球,由于人口的快速增长,变得越来越拥挤,污染越来越严重。

辨析：

fast,quick和rapid

【梳理】

1）fast既可用作形容词又可用作副词,主要表示人或物体本身的速度快,如汽车开得快、人走得快、时间过得快等。

2）quick常用作形容词,主要表示反应快、动作敏捷。

3）rapid是正式用语,只用作形容词,语气较强,常用于表示抽象意义的“快速的”,如价格涨得快、社会变革快等。

【运用】

选用fast,quick或rapid填空。

1）Mybrotheratea________breakfastandwenttoschoolinahurry.

2）Tomrunsso____thatIcan’tcatchupwithhim.

3）Wesawthe______developmentofthesocietytheseyears.

2.ItishopedthatpeoplecouldstartalloveragainandbuildabetterworldonMars.

人们有望能够在火星上重新开始，建设一个更好的世界。

句型Itishopedthat…表示“……可以指望”，指说话者希望如此。

如：

我们希望在本周前完成此项目。
