Ⅰ.单项填空

1．—What is his suggestion?

—Just guess the meaning of it whenever you ________ a new word in reading.PHjxK1AemD

A．come in B．come at

C．come across D．come about

答案与解读：C 句意：——他的建议是什么？——在阅读中无论什么时候遇到一个新单词，你都可以去猜测它的意思。根据句子的意思可知应该选C，come across意为“碰到，偶遇”。come

in“进来”；come at“攻击，冲向”；come about“发生，产生”，均不符合句子的意思。PHjxK1AemD

2．It's my daily duty to have the English newspapers ________ to the senior students.PHjxK1AemD

A．printed B．published

C．delieved D．advertised

答案与解读：C 句意：把这些英语报纸分发给高中生是我每天的任务。deliver有“交付，递送”的意思。print“印刷”；publish“出版”；advertise“登广告”，均与句子意思不符。PHjxK1AemD

3．—What are the students ________ about?

—Whether Senior 3 students should join in the coming school sports meet.PHjxK1AemD

A．quarrelling B．inspiring

C．fighting D．arguing

答案与解读：D 句意：——学生们在争论什么？——高三学生该不该参加即将来临的学校运动会。argue有“争论”的意思，符合句意。quarrel“争吵，吵架”，inspire“鼓舞，激起”，

fight“打架”，均不符合句子的意思。PHjxK1AemD

4．________ with so many fans of the famous star, the stadium is hard for us to enter.PHjxK1AemD

A．Crowding B．To be crowded

C．Crowded D．Crowded out

答案与解读：C 句意：体育馆挤满了这位明星的粉丝，对于我们来说要进去是很难的。此处是过去分词作状语，crowd与the stadium之间是被动关系，所以要用过去分词。PHjxK1AemD 5．________ the stars carefully, and you will find that they are not shining themselves.PHjxK1AemD

A．Observe B．Notice

C．Glance D．Mind

答案与解读：A 句意：仔细观察这些星星，你就会发现它们本身是不发光的。observe“观察”；notice“注意”；glance“看一眼，扫视”，是不及物动词；mind“介意，注意”。只有observe 符合句子的意思。PHjxK1AemD

6．After doing market research, all the researchers think it ________ to invest a large sum of money in the project.PHjxK1AemD

A．worthless B．priceless

C．valuable D．worthwhile

答案与解读：D 句意：做过市场调研之后，所有的研究者都认为在这个工程上投资一大笔钱是值得的。由于后面是动词不定式，故要用worthwhile，表示“值得(去做某事>”。PHjxK1AemD 7．Liu Xiang ________ his experience during the World Track and Field Events when being interviewed by

Reuters.PHjxK1AemD

A．spoke to B．referred to

C．contributed to D．talked to

答案与解读：B 句意：刘翔在接受路透社的采访时谈到了他在世界田径赛上的经历。speak to“和某人说话”；refer to“谈到，提及”；contribute to“导致，引起”；talk to“对……讲话”。只有refer to符合句子的意思。PHjxK1AemD

8．Only when he returned from the exchange program

________ how much he enjoyed it.PHjxK1AemD

A．he knew B．he had known

C．did he know D．had he known

答案与解读：C 句意：直到从交换工程上返回时，他才知道自己是多么喜欢它。“only＋状语(从句>”位于句首时，句子要部分倒装，排除选项A和B；根据从句中的谓语动词returned可知此处要用一般过去时，故C项正确。PHjxK1AemD

9．Greatly ________， the students made up their minds to carry ________ the experiment.PHjxK1AemD

A．inspiring; out B．inspired; on

C．inspire; through D．inspire; away
