Ⅰ.单项填空
1.D 句意为:你认为他到这里有多久了?since自从,引导的状语从句用一般过去时态,主句用现在完成时态,指段时间可用一般现在时态。
2.D 此处sound为连系动词,意为“听起来”,后面可用形容词、名词或介词短语作表语。此处省略了主语that或it。
3.A 多个形容词修饰名词时,排列顺序通常是关系最密切的离名词最近。我们平时常用“九字令(限、描、大、形、龄、颜、籍、物、类)”来给名词前的形容词排序。句意为“一位朋友告诉我这儿附近有一家不错的小海鲜餐馆。我们去那儿吃午饭吧,怎么样”?
4.B 本题考查动词ed形式短语作定语。theparty与hold之间是被动关系,因此用held。tobeheld表示未发生;held表示已发生;beingheld表示正在发生。根据答语“是的,实际上我参加了那次聚会”,可知已发生。
5.D exhausted意为“筋疲力尽的”,为形容词作状语,说明主语的特征。句意为“直到她完成所有的工作才筋疲力尽地回到家”。
6.A since意为“自从”,表示时间或动作的起点。当since表示从过去的一个时间点延续至说话的现在时,通常要求主句使用现在完成时,而since从句用一般过去时。句意为“你教英语很长时间了吗?”“是的,自从大学毕业至今”。
7.C 本句为“Thisis+序数词+time(that)+现在完成时”这一句型。句意为“这是你第一次来北京吗?你对这个城市的印象如何”?
8.D 句意为:很抱歉在这样的场合麻烦你回答那么多的问题。考查短语bothersb.withsth.用……来打扰某人,C项虽也可以用impresssb.withsth.,但与句意不符。
9.B 根据题意“除了百万富翁外谁能付得起钱买这么贵的汽车呢?”可知“买得起,付得起”应用afford,另外,四个词中只有afford可直接跟不定式。
10.B anapproachto...意为“……的方法”,其中to为介词,后跟名词、代词或动名词。
Ⅱ.阅读理解
先进的科学技术让人们变得越来越无隐私可言,很多人对保护隐私这个问题言行不一,或许只有当我们失去它的时候才会知道它的宝贵。
1.C 考查细节理解。根据文章第三段第一句可知,即使与朋友之间也要有明确的界限,即要保持一定的距离。
2.B 考查推理判断。根据文章第三段中所举的事例可知人们在使用现代技术的时候会留下一些痕迹,从而泄露了自己的秘密。
3.D 考查推理判断。根据文章第四段和第五段可知,美国人对于保护隐私的问题说的和做的不一致。
4.D 考查细节理解。根据文章最后一段可知,隐私就像健康一样,只有当我们失去的时候才知道它的珍贵。
5.B 细节理解题。由文章第二段中的Inherletter,Gracetoldhimthatheshouldlethiswhiskersgrowbecausehisfacewas“sothin”.可知,Grace建议林肯留胡子是因为留了胡子能使他的脸看起来不那么瘦。由此可以推断Grace提建议是为了使林肯的外在形象更好。
6.D 细节理解题。由林肯信中的一句话IregretthenecessityofsayingIhavenodaughters...可知,林肯觉得没有女儿是个遗憾。
7.C 细节理解题。从文章内容可知,Grace写信建议林肯留胡子时,他没有采纳,但是后来当选总统后改变了主意决定留胡子,并在去华盛顿的途中与Grace见面了,由此可知他心里一直记着小女孩的建议。
8.A 推理判断题。文章最后一段提到Grace连准备送给林肯的花都忘了送出,由此可以推断,她见到林肯时很紧张。
9.B 推断理解题。从文中可知林肯的形象是高的黑色帽子、蝴蝶结领结和胡须,故图片B为正确答案。
