on中，词组的意思相当于affect。effect也可以用作及物动词，但意思完全不同，作“使发生，产生结果”解。(3)influence既可用作名词，也可用作动词，通常指通过说服、举例等对行动、思想、性格等产生不易觉察到的、潜移默化的影响。常用的短语搭配：have an influence on sb./sth.对某人/某事物有影响。(牛津P1046)What exactly is the

Dwhen解析：选C。考查同位语从句的引导词。句意为：你同意后天我们召开一个晚会的建议吗？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。8 .settlevi. 定居vt. 解决(回归课本P14)The history of the city goes back 650 years when the

along解析：选A。come along走过来，快点，进行，一道去；settle down定居。空格前有连词and说明所填选项与moved是并列谓语，所以排除B、D两项。句意：正是由于这种原因她叔叔搬出纽约，在一个小村庄定居。9 .viewn风景；视野；观点(回归课本P14)In the city，you can enjoy an amazing view from the Sky Tower.在这个城市，从天空宝塔你可以欣赏得到令人惊异的景色。hold different views持不同的观点come into view看得见，出现in view (of sb./sth.)在的视野中in ones view在某人看来in view of鉴于；由于view on/about/that.有关的看法/意见归纳拓展(朗文P1715)The only viewA big red

you句型梳理1【教材原句】.，“it_is_clear_that we are going to see a huge growth in shopping on the Internet.”(P8)，“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。There 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。John 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。归纳拓展it替代后面that引导的从句作形式主语的句式有：(1)It isadj.(clear，apparent，obvious，possible，probable，likely，certain，natural.)thatclause(谓语形式用陈述语气)(2)It is n.(a pity，shame，ones duty，no use，no good，no wonder，no surprise.)thatclause(谓语形式用陈述语气)(3)It isp.p.(said，believed，known，recorded，estimated，announced，expected.)thatclause(谓语形式用陈述语气17_ disappeared as time went on that he was afraid of climbing high mountains.AIt BThatCWhat DWhich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。2【教材原句】But I still find_it_hard_to_imagine.(P12)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)(牛津P754)You may find your illness hard to accept.你可能觉得难以相信自己患病。(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。Have you found anyone to replace her yet?你找到代替她的人没有？I found my vase broken on the ground.我发现我的花瓶碎在了地上。18So difficult did I find _ to work out the problem that I decided to ask my partner for help.Amyself BusCthat Dit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。3【教材原句】 In 1985，the New Zealand government made_the_whole_country_a_nuclearfree_zone.(P14)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：In 1949，they made Beijing the capital of New China.在1949年，北京成为新中国的首都。Can you make it suitable for children?你能不能使它更适合孩子？We made him monitor of our class.我们选他当班长。【温馨提示】表示官街、职位的名词作宾补时，其前无冠词。19完成句子(1)电脑使英语学习更加容易。Computers make _ easier to learn English.答案：it(2)他大声喊叫，使整个房间都能听到他的声音。He
