20、系统,它可以取代谷歌的Android操作系统。1.【解析】is aimed。考查一般现在时态的被动语态。句意:美国政府推迟了对华为技术有限公司(Huawei Technologies Co)的技术销售禁令,此举旨在减少对这家中国科技巨头的全球客户和供应基地的影响。此处move是先行词,在后面的定语从句中作主语,且move和aim之间是一种被动关系,句子用一般现在时态,故填is aimed。2.【解析】response。考查固定搭配。句意:作为对这一举措的回应,华为创始人兼首席执行官任正非周二表示,美国政府90天的延期“意义不大”,并补充称,该公司已准备好应对禁令,并为最坏的情况做好了准备。固定

21、搭配:in response to“对有反应”。故填response。3.【解析】adding。考查现在分词作伴随状语。句意:美国政府的90天的延期并不意味着什么,他补充称该公司正准备处理这个禁令,并准备好应对最坏情况。此处句子主语Ren Zhengfei和add之间是一种主动关系,是现在分词作伴随状语,故填adding。4.【解析】with。考查固定词组。句意:美国政府的90天的延期并不意味着什么,他补充称该公司正准备处理这个禁令,并准备好应对最坏情况。固定词组:deal with“处理,解决”。故填with。5.【解析】preparations。考查固定词组。句意:美国政府的90天的延期并

22、不意味着什么,他补充称该公司正准备处理这个禁令,并准备好应对最坏情况。固定词组:make preparations for“为做准备”。故填preparations。6.【解析】has developed。考查动词时态。句意:华为表示已经开发了自己的手机操作系统。结合句意可知句子用现在完成时态,句子主语是it,故填has developed。7.【解析】which。考查非限制性定语从句。句意:华为表示,它已经开发出自己的手机操作系统,它可以取代谷歌的Android操作系统。此处system作先行词,指物,在后面的非限制性定语从句中作主语,that不能引导非限制性定语从句,故填which。8.【解析】determination。考查名词。句意:外交部发言人陆慷周二表示,中国政府有维护自身合法权益的坚定决心和能力。此处strong是形容词,修饰名词,故填determination。9.【解析】What。考查主语从句。句意:要求两国经济在贸易上绝对平等地开放是不现实的。此处是主语从句作主语,从句缺少引导词,且从句也缺少主语,所填词应该起双重作用,故填What。10.【解析】beneficial。考查固定词组。句意:协议必须是平衡的,对双方都有利。固定词组:be beneficial to“有益于”。故填beneficial。本课结束
