A．a B．an C．the D．/
【答案】A
【详解】句意:晚饭后，我通常带我的宠物狗去公园散步。
考查冠词用法。a表泛指，不定冠词，用于以辅音音素开头的单词前;an表泛指，不定冠词，用于以元音音
素开头的单词前;the表特指，定冠词;/表示不填，零冠词。根据take my pet dog for... walk可知，此处是指遛
狗，考查take...fora walk“遛(宠物);去散步”，动词短语。故选A。
2. —I haven’t been to the Bird’s Nest. What about you?
—________. I am planning to go there this weekend.
A．Me too B．Me neither C．So did I D．Neither did I
【答案】B
【详解】句意:--我没去过鸟巢。你呢?-我也没有。我计划这个周末去那里。
考查倒装句。Me too我也是，用于肯定句;Me neither我也没有，用于否定句;So did I我也是，用于肯定
句;Neither did I我也没有。根据I haven't been to the Bird's Nest.以及I am planning to go there this weekend.可
知，此处表示“我也没有(去过)”，排除A、C项。根据I haven't been to the Bird's Nest..为现在完成时可知，
D项为一般过去时，需排除。故选B。
3. —________ I ask the teachers for help?
—No, you needn’t. You can ask your classmates for help. ________ of your teachers is free as they’re having a
meeting.
A．Must; Both B．May; Neither C．Must; None D．Need; All
【答案】C
【详解】句意:--我必须向老师寻求帮助吗?--不，你不需要。你可以向你的同学门寻求帮助。你的老师们都
没有空因为他们正在开会。考查情态动词和代词。must必须;may可能;need需要;both(两者)都;a(三者或三者
以上)都;neither(两者)都不;none(三者或三者以上都)不。must为情态动词，它引导的一般疑问句要用 No,you
needn't.来回答。根据后文as they're having a meeting可知，老师们都没有空，不止两位老师。故选C。
4. —Can I ________ Robinson Crusoe?
—Sure, it’s very interesting, but you can only ________ it for two weeks.
A．borrow; lend B．lend; borrow C．borrow; keep D．lend; keep
【答案】C
【详解】句意:--我可以借《鲁宾逊漂流记》吗?--当然，它很有趣，但是你只能借两个星期。
考查动词辨析。borrow借入，短暂性动词;1end借出，短暂性动词;keep保持，这里强调保管，延续性动词。
根据“Can1.Robinson Crusoe?"可知，此处强调借入，所以前句用borrow;后句句中for two weeks是一段持续的时间，第二个空需用延续性动词keep。故选C。
5. —We will enter a good high school ________ we work hard.
—I agree. Work hard enough and our dream will come true one day.
A．as soon as B．as long as C．as far as D．as well as
【答案】B
【详解】句意:--只要我们努力学习，就一定能考上好高中。--我同意。努力学习，总有一天我们会梦想成
真。考查从属连词辨析。as soon as....就..; as long as只要;as far as就….而言;as well as也。根据“We will
enter a good high school...we work hard.”“可知，此处指努力学习是考上好高中的条件，应用as long as“只要”
引导条件状语从句。故选B。
6. Daniel is ________ to help his friends ________.
A．enough kind; all the time B．such kind; at times
C．too kind; at a time D．kind enough; from time to time
【答案】D
【详解】句意:丹尼尔很善良，不时帮助他的朋友。
考查enough的用法和介词短语辨析。enough kind错误表达;all the time总是;such kind如此善良的;at times有
时;too kind太善良，后接不定式表否定意义;at a time一次;kind enough足够好;from time to time时常。enough
足够，用作副词需放在被修饰的词后面，后接不定式短语;根据to help his friends，可知丹尼尔足够善良，所
以时常帮助他的朋友。结合选项，故选D。
7. —I don’t know how to fill out the form. Can you help me?
—________
A．Thank you very much. B．That’s too bad. C．Sure, no problem. D．Good luck.
【答案】C
【详解】句意:--我不知道怎么填这张表。你能帮我吗?--当然，没问题。
考查情景交际。Thank you very much 非常感谢你;That's too bad 太糟糕了;Sure, no problem 当然，没问
题;Good luck祝你好运。根据Can you help me可知，此处为请求对方帮忙，故应同意或拒绝，选项 C“当
然，没问题”符合情景。故选C。
8. —Bob, hurry up! We only have 15 minutes.
—Oh, Dad, 15 minutes ________ enough for us.
A．is B．have C．were D．was
【答案】
【详解】句意:--鲍勃，快点!我们只有15分钟了。--哦，爸爸，15分钟就够了。
考查主调一致。根据15 minutes... enough for us.可知，表示金钱、时间、距离、长度等的复数名词、词组作
主语时，一般被看作一个整体，谓语动词常用单数形式;主语“15 minutes”是一个整体，be动词用is。故选A。
