二、单项选择题。

1.[答案]A

[解析]句意: ——Sarah正忙于将她的小说改编成电影。——噢!

难怪我最近到处都看不到她。根据语境可知Sarah现在正在忙，these days“最近”也在提示此题应用现在完成时，故选择A项。

2.[答案]D

[解析]句意:直到现在，数以千计的红色电话亭,英国的古老形象,由于手机的使用已被拆除。根据时间状语Up to now可知设空处需用现在完成时;主语thousands of red phone boxes与remove之间为被动关系，故需用被动语态，故答案为D项。

3.[答案]C

[解析]句意: ——瞧，已经有人打扫了沙发。——嗯，不是我，我没做过那件事。本题考查动词时态的基本用法。根据Look!可知，设空处表示现在的情况，故用现在时，排除B、D两项; A项表示现在正在进行，不符合句意要求。现在完成时表示该动作对目前所造成的影响或结果，即现在沙发很干净。

4.[答案]B

[解析]句意:——你猜我是谁?——抱歉，我想不起你的名字了。

根据句意可知说话者现在不知道对方的名字，故设空处表示现在的情况，需用现在时，排除A、C两项; slips表示目前的习惯性动作，不合句意。现在完成时可以表示过去的动作对现在的影响，故B项为答案。

5.[答案[C

[解析]句意:到目前为止，一切进展良好。我们确信工作能够按时完成。根据so far (=by now)可知，此处要用现在完成时。

6.[答案]C

[解析]句意:这里有点乱，真抱歉。现在房子正在被粉刷。根据题干中的at the moment可知语境在描述当前的情况，且房子与粉刷为被动关系，故选择C项。

7.[答案]D

9.[答案]B

[解析]句意为:我记得昨晚把笔记本落在书房了。它怎么跑到这里了?哦，我以为你需要它，所以就给你带来了。根据答语可知，come所表示的动作已经发生，要用现在完成时。故B项正确。

四、语法填空

阅读下面材料，在空白处填入适当的内容 (1个单词) 或括号内单词的正确形式。 

[答案] have been found；When；to spot；like；out；it；unexpected；and；more；for  

[解析]本文是一篇说明文，介绍了人们对于恐龙灭绝的不同观点。
(1)考查时态语态。句意：最近，中国科学家在河南省南阳发现了很多种恐龙骨头。由“recently”可知，本句的时态为现在完成时，主语Many kinds of dinosaurs' bones和动词find之间是被动关系，所以用被动语态，故填have been found。
(2)考查连词。句意：当科学家们检查这些骨头时，他们惊讶地发现这些恐龙不仅能像其他恐龙一样奔跑，而且还能爬树。分析句子可知，此处缺少从属连词引导时间状语从句，故填When。
(3)考查非谓语动词。be surprised to do sth.惊讶地做某事，故填to spot。
(4)考查介词。like作介词意为“像”，根据句意可知，此处应填like。
(5)考查副词。句意：恐龙在大约6千万年前突然灭绝。die out固定短语，“灭绝”故填out。
(6)考查代词。think 后接省略that的宾语从句，宾语从句中缺少主语，主语指的是恐龙灭绝这件事，用it来指代，故填it。
(7)考查形容词。unexpected意外的，应用形容词修饰名词incident，故填unexpected。
(8)考查连词。when引导的时间状语从句中缺少连词来连接hit和put，hit与put为并列关系，故填and。
(9)考查固定短语。not any more固定短语，“不再”。本句的否定词隐含在前文的too...to… (太……而不能) 中，故填more。
(10)考查介词。句意：没人确切地知道恐龙为什么在这么短的时间内从地球上消失以及是如何消失的。for sure固定短语，“确切地”，故填for。
[点评]本题考点涉及时态语态，连词，非谓语动词，介词，副词，代词，形容词等多个知识点的考查，是一篇科普类阅读，要求考生在理解细节信息的基础上，进一步根据上下文的逻辑关系，并结合相关语法知识，进行分析推理，从而写出正确的单词形式。
