(to) do sth.“帮助某人做某事”，to可省略，故填(to) get。 6．句意：一些年轻人花太多时间在手机上玩游戏。spend time (in) doing sth.“花费时间做某事”，动词短语，故填动名词形式playing作宾语。 7．句意：他们的父母经常告诉他们不要这样做，但他们不听。tell sb. not to do sth.“告诉某人不要做某事”，动词短语，故填动词不定式not to do。 8．句意：上周，我朋友汤姆的妈妈让他交出手机三天。make sb. do sth.“让某人做某事”，make为使役动词，后接不带to的动词不定式即give。 9．句意：但后来他开始读书，并觉得很有趣。start to do sth.和start doing sth.均可表示“开始做某事”，故可填to read或reading。 10．句意：他说数字设备帮助我们很多，但我们应该明智地使用它们。根据“said”可知，宾语从句的主句是一般过去时，从句陈述的是客观事实，可用一般现在时，主语digital devices为复数，动词help用原形。 八．选词填空 请从方框内选择适当的词并用正确的形式填空，使文章完整连贯。注意每空一词，每词仅用一次，有两词为多余项。 impossible   family   quick   they   what   come   use   in   do   with   drive   and There are robots all around us.

It makes our lives more convenient and colourful. Firstly, technology is playing an important role in our lives.It has made our daily lives easier. With the help of technology, we can study online, chat with friends who live far away from us. There are some robots that can deliver food to our tables. Secondly, technology has made our lives more colourful. We can get a lot of pleasure by watching TV, listening to music and watching short videos. 　　We are middle school students. We can use technology, but we can't rely on it too much. For example, if we spend too much time watching short videos, we might waste a lot of time. So we should learn to use technology wisely. 1 学科网（北京）股份有限公司 $
