copies of the book _.A.be destroyed B.should destroyC.were destroyed D.was destroyed提示:根据动词command的用法，宾语从句的谓语动词应该使用(should) do 结构，且此处应该表示被动。答案:A3.praise讲: v. n. 称赞；赞扬；赞美短语:praise sb./sth.for.因为赞扬praise sb./sth.as sth.赞扬为in praise of为赞扬sing high praise for高度赞扬例:The guests praised the meal.客人们称赞这顿饭做得好。He was obviously expecting to be praised.他显然想要得到表扬。He praised her for her

out.我们的燃料快用光了。Our food soon ran out.我们的食物很快就吃完了。Were running out of time.我们快没有时间了。链接拓展(1)比较:run out 和run out of的区别。run out of为及物动词短语，run out为不及物动词短语，在使用时要注意动词的语态。(2) run构成的短语还有run into撞上；run across不期而遇。His car ran into the tree.他的汽车撞到了树上。I ran across an old friend in the street.我在街上和一位老朋友不期而遇。练: _his food_ ,the man had to come out of his hiding place.A.Since;run out of B.Because;run

Red Sea civilisations from the earliest times.众所周知，非洲从早时开始，就已经同印度和红海文明有过接触。It is well known that.表示“众所周知”，其中it为形式主语，that引导的从句是真正的主语。例:It is well known that the earth is round.As we know,the earth is round.As is known(to us all),the earth is round.众所周知，地球是圆的。It is well-known that Edison invented the electric lamp.众所周知，是爱迪生发明的电灯。链接提示注意比较该句型和“As we know, +主句”及“As is known, +主句”的区别，三个句型表示的意思是一样的，但是结构不同。It is known that.为主语从句形式，后面用that引导真正的主语；而as引导的是从句，后面使用逗号，然后跟主句。练: _it takes years of practice to gain the skills of an expert.A.As is known that B.It is known to us thatC.As we know that D.It is known to us提示:本题主要考查了表示“众所周知”的几个句型结构上的不同。答案:B2.v.ing形式作伴随状语讲:请注意观察下面教材原句:.Zheng sent a message to the king and to other African states,inviting them to send ambassadors.郑和向这位国王和其他非洲国家发出了邀请，请他们派使者来该句子中的inviting them to send ambassadors可以理解为伴随状语，可以改为and连接的并列谓语结构:.states and invited them to send ambassadors。例:He sat there in silence,looking sad and doing nothing.他默默地坐在那里，看上去很难过，什么也没做。The secretary worked late into the night,preparing a long speech for the president.秘书工作到深夜，为总统准备一个长演讲稿。链接提示注意使用v.-ing形式作伴随状语时，v.-ing的逻辑主语应该和句子的主语一致，即表示主谓关系；如果是逻辑动宾关系，则使用过去分词形式表示伴随的动作。如:In order not to be disturbed, I spent three days locked in my study. 在spend time doing sth.这一句型中，doing应该表示主动，而此处的动词lock按句子的意思应该为被动，所以使用过去分词。练:Mr.Macfarland completed the course successfully, _ all with his excellent performance.A.surprised B.surprising C.to surprise D.having surprised提示:v.-ing形式作伴随状语，其逻辑主语为Mr Macfarland。答案:B辨析1.worth,worthwhile,worthyworth adj. 值；值得结构:(1)be worth+money=cost 值；(2)be worth doing值得做某事(这种结构中的动词-ing形式，在逻辑上与前面的主语具有动宾关系，但该词不能用被动式)(3)表示“很值得”时用well修饰。(4)可用引导词it作be worth的形式主语。worthy adj.值得的短语:be worthy of sth.值得be worthy of being doing 值得做某事be worthy to be done 值得做某事worthwhile adj.值得花时间做某事，可以作定语。结构:be worthwhile doing/to do值得做某事即时练习:(1)I only paid $1000 for the car but it is _ a lot more.(2)This book is _ reading a second time.(3)What he did is _ praise.(4)This book is _
