5、n you are a kid _ determines your brain structure for the rest of your life.A.sooner or later B.more or lessC.to and from D.up and down答案B解析考查习惯表达。句意为：几十年前，科学家们认为，当你还是个孩子的时候，大脑是如何发育的或多或少决定了你余生的大脑的结构。sooner or later迟早；more or less或多或少；to and from来来回回；up and down上上下下。根据题意，故选B。6. go for a holiday?A.Whe

7、een working；haveB.have worked；hadC.am working；will haveD.had been working；had had 答案A解析考查时态。句意为：我最近工作太忙了，没时间帮你学数学。没关系我自己能搞定。由“recently”可知，本句为现在完成进行时，表示动作还可能持续下去，而第二个空表示现在所处的状态，所以用一般现在时。故A选项正确。 8.Parkour(跑酷) is a very popular sport among the youngsters in cities， the only equipment required is a good
8、 pair of shoes.A.which B.thatC.where D.what答案C解析先行词sport为抽象化地点，从句中缺少地点状语，故用where引导定语从句。9.If he had visited me in Beijing，I him to see the sights.A.had taken B.will takeC.would take D.would have taken答案D解析此题考查虚拟语气，从句时态为过去完成时，主句应用should/would/might/couldhave done，故选D，其他选项均不符合虚拟语气中的时态要求。10.What has mad
9、e him in such high spirits recently? by his teacher for succeeding in passing the exam.A.Being praised B.PraisedC.Having praised D.To praise答案A解析通过分析语境可知这里应该用动名词短语作主语，并且表示被动。11.He is eager to try something he has never tried before.Oh，I see.Thats hes different from others.A.when B.whereC.how D.what答
10、案B解析考查表语从句。疑问副词where引导表语从句，where在从句中作地点状语。句意为：他渴望尝试一些以前没有尝试过的事情。我明白。那就是他和别人不一样的地方。故B项正确。12.How could you have trusted the online dictionary so much in translating your resume?Well，I never expected it should translate it so .A.literally B.originallyC.sufficiently D.professionally答案A解析考查副词。句意为：你怎么能这么相

12、 D.the one答案C解析考查代词的用法。one 表示泛指，相当于“a(n)名词”，代替的是同类事物中的“一个”；that表示特指，相当于“the名词”；此 处one“a”product-making power；而_ driven by innovation and emphasizing quality over quantity 中driven by 只是一个非谓语动词短语(be driven by 被驱使)作定语，因此不需要连词引导。所以排除A、B；D项与题意不符。句意为：“2025 中国制造”的目标是把中国从一个产品制造工厂变成一个产品制造大国，一个以创新为导向、强调质量而不是数
13、量的大国。故选C。14.The sustainable development is a simple idea，but that is difficult to put into practice.A.it B.that C.one D.this答案C解析one此处作为不定代词，替代单数可数名词。onean idea。15.What about inviting Tracy to host the party?Good idea!
