15、 also.连接两个并列的动作run和climb。归纳拓展they were surprised to find属“主语be形容词to do”结构，这一结构中的形容词往往是表示心理活动的词；接不定式时，不定式的逻辑主语是句子的主语，且经常使用不定式的主动形式，不定式表原因。用于这一句式结构的形容词有surprised,moved,disappointed,pleased,happy,sad,delighted,sorry,interested,glad,worried,eager,anxious,angry等。We were disappointed to hear it.听到这件事我们失望了

19、 of是定语从句，从句中动词短语thought of缺少宾语，故用which或that引导。8They lived on the earth tens of millions of years ago,long before humans came into being and their future seemed secure at that time.千百万年前它们就在地球上生活，比人类的出现要早得多，它们的未来在那时看似很安全。句式分析(1)这是一个由and连接的并列句。(2)在第一个分句中含有before引导的时间状语从句。before“在之前”。Even great men hav

24、ing bitten;lying考查afraid的用法以及非谓语动词。be afraid to do sth.害怕做某事；be afraid of doing sth.担心做某事；dog与lie(躺)之间为主动关系，且表示正在进行，因此应用现在分词。6.Most companies marketing effort is focused on getting customers，with little attention _(pay)to keeping them.答案：paid考查非谓语动词。句意：大部分公司的营销工作以赢得顾客为中心，而很少注意留住他们。本句的后半句是介词with的复合结构

25、，attention和pay之间是动宾关系，所以用过去分词表示被动。7_ the dog is fierce,it never harms people.答案：Though/Although句意：尽管这只狗很凶猛，它从不伤害人。8Before the foreigner entered that country,his passport _(inspect)by the customs official.答案：was inspected考查动词词义辨析。句意：在这个外国人进入那个国家前，海关官员查看了他的护照。.完成句子1Because of _，he was rushed to hospit
