本题为语境型选词填空,需先通读短文把握主旨(介绍电脑这一发明对生活的改变),再结合每个空的句子结构、词性要求、固定搭配及上下文语境,从方框内单词中选择并转换为适当形式填空。
【解析】
1. 句意:我写信告诉你我最喜欢的发明。favourite后需接名词,方框中invent的名词形式为invention,符合语境,故填invention。
2. 句意:它极大地改变了我们的生活。此处修饰动词changed,需用副词,great的副词形式为greatly,故填greatly。
3. 句意:现在,在互联网的帮助下,我们可以在家轻松搜索所需信息。结合上下文“在家找信息”,对应方框内的Internet,故填Internet。
4. 句意:我的电脑连接到网络,所以我可以和朋友在任何地方交流。be connected to是固定搭配,意为“连接到”,故填connected。
5. 句意:许多困难的工作可以被电脑在几秒内完成。jobs与do是被动关系,情态动词的被动结构为“can be + 过去分词”,do的过去分词是done,故填done。
6. 句意:它们高速工作且从不疲倦。at a high speed是固定短语,意为“高速”,故填speed。
7. 句意:当我有空时,我经常在屏幕上看电影或听音乐。结合语境“看电影、听音乐的载体”,对应方框内的screen,故填screen。
8. 句意:事实上,我无法想象没有它我的生活会是什么样。in fact是固定短语,意为“事实上”,故填fact。
9. 句意:当然,我父母经常警告我不要花太多时间在上面,因为对眼睛不好。warn sb not to do sth是固定搭配,主语parents为复数,时态为一般现在时,故填warn。
10. 句意:请回信并分享你的想法。此处与write back并列,需用动词原形,share ideas意为“分享想法”,故填share。
