　　(3)It is＋p.p.(said，believed，known，recorded，estimated，announced，expected...)＋that-clause(谓语形式用陈述语气),(4)It＋vi.(seem，occur，happen...)＋that-clause(谓语形式用陈述语气) ①There are few clouds in the sky.It is clear that the weather will soon turn out fine. 天上几乎没有什么云彩了,很显然天气很快就要转晴. ②John works very hard.It_is_quite_possible_that he will pass the College Entrance Exam next month. 约翰学习非常刻苦,他通过下月的大学入学考试是完全可能的. 2(教材P12)But I still find_it_hard_to_imagine. 但我还是觉得令人难以想像.

　　【句法分析】本句型中的it是形式宾 语，指代后面的不定式to imagine，而形容词hard在句中则为宾语补足语。在“find＋宾语＋宾语补足语”句式中，find的含义为“发现，觉得”或“发现……处于某种状态”，其常见结构有： (1)find＋宾语＋形容词/副词/介词短 语；(2)find＋宾语＋现在分词(现在分词与宾语是主谓关系或表示动作的进行或持续)； (3)find＋宾语＋过去分词(过去分词与宾语是动宾关系或表示动作的完成)； (4)find＋宾语＋名词(名词与宾语是系表关系)。 ①(牛津P754)You may find your illness hard to accept. 你可能觉得难以相信自己患病. ②(牛津P754)She woke up and found_herself_in_a_hospital_bed.她醒来发现自己躺在医院的病床上. ③Peter,who was usually shy,found himself talking to the girls.彼得通常很害羞,却发现自己不知不觉已在跟女孩子们说话. ④I found_my_vase_broken on the ground. 我发现我的花瓶碎在了地上. 3(教材P14)In 1985,the New Zealand government made_the_whole_country_a_nuclear-free_zone... 在1985年,新西兰政府使全国成为无核区域…… 【句法分析】“make＋宾语＋宾补”这一句式结构中make为使役动词，常构成如下结构： ①In 1949,they made Beijing the capital of New China. 在1949年,北京成为新中国的首都. ②Can you make_it_suitable for children? 你能不能使它更适合孩子？ 跟踪训练 Ⅰ.完成句子 1．这消息使她高兴. The news_______________________。 made/makes her happy 2．她说的笑话把我们都逗乐了. Her jokes________________all_________. 3．你能用英语把意思表达清楚吗？ Can you _______________________in English? made/make us laugh make yourself understood Ⅱ.单项填空 1．So difficult did I find ________ to work out the problem that I decided to ask my partner for help. A．myself

　　B．us C．that

　　D．it 解析：选D.考查“find＋宾语＋宾语补足语”结构.本句是so引导的倒装句,可还原为：I found it so difficult to work out the problem that I decided to ask my partner for help.根据句子结构可推知用it作形式宾语,而真正的宾语为后面的不定式短语to work out the problem. 2．________ disappeared as time went on that he was afraid of climbing high mountains. A．It

　　B．That C．What

　　D．Which 解析：选A.考查it作形式主语.句意：随着时间的推移,他对爬高山的恐惧感消失了.首先忽略as time went on这一时间状语,就会发现that从句是真正的主语.而四个选项中只有it可作形式主语. 3．When he came to life,he found himself________to a tree,with his mouth filled with a towel. A．to tie

　　B．tying C．being tied

　　D．tied 解析：选D.句意：当他醒来时他发现自己被捆在树上,嘴里塞了一条毛巾. himself与tie之间为被动关系,故应用过去分词形式作宾语补足语. 4．________is difficult to imagine his accepting the decision without any consideration. A．It

　　B．That C．What

　　D．Which 解析：选A.考查it作形式主语.句意：很难想像他会不假思索地就接受了这个决定.it作形式主语,真正的主语是不定式：to imagine his accepting.... 温馨提示 请做课时作业　必修二　Unit 4 本部分内容讲解结束 按ESC键退出全屏播放 解析：选C.考查同位语从句的引导词.句意：你同意后天我们举办一个晚会的建议吗？从句意看,suggestion后面的从句为同位语从句,且语意完整,故用that引导,that在名词性从句中没有任何意 义,只起连接作用. 7．After I waited for a very long time, the manager made a phone call to me yesterday ________ me a good job at last. A．giving

　　B．providing C．supplying

　　D．offering 解析：选D.句意：我等了很长时间之 后,昨天那位经理给我打来电话,最终提供给我一份不错的工作.offer“提供”符合句意和结构,B、C两项的句式结构不对,A项含义不对. 8．Most of us know we should cut down on fat,but knowing such things isn’t much help when it________shopping and eating. A．refers to

　　B．speaks of C．focuses on

　　D．comes to 解析：选D.refer to查阅,提到;speak of谈及,说到;focus on集中于;come to意为“达到,涉及”,符合句意.

　　句型巧析 1(教材P8)．..,“it_is_clear_that we are going to see a huge growth in shopping on the Internet.” ……,“很显然,我们将会看到网上购物的大幅度增长.” 【句法分析】句中it为形式主语，真正的主语为that引导的主语从句，在主语从句中，that不作句子成分，但不可以省略，主语从句常用it作形式主语，当然也可以将从句置于句首直接作主语。it替代后面that引导的从句作形式主语的句式有： (1)It is＋adj.(clear，apparent,obvious，possible，probable，likely，certain，natural...)＋that-clause(谓语形式用陈述语气) (2)It is ＋n.(a pity，shame，one’s duty，no use，no good，no wonder，no surprise...)＋that-clause(谓语形式用陈述语气) 归纳拓展 辨析
