17、和against后面常跟sth.，有时against后跟being done来强调动作的被动性。(3)主动句中prevent/stopfrom中的from可省略，在被动句中from不可省略，而keepfrom中的from无论在主动句还是在被动句中都不能省略，因为keep sb. doing sth. 的语义是“让某人一直做某事”。单项填空 ()(1)He is wearing sunglasses to _ his eyes from the strong sunlight.

(P30) 当时有许多不同种类的恐龙，其中有很多种类曾经生活在中国。 “There be 名词”是英语中最为常用的句式之一，表示“某处存在某物”。在使用中，我们应当注意以下几点：(1)there be 中的be动词的数的变化要依据“就近原则”，即与它距离最近的主语在人称和数上保持一致。There is a pen a

23、nd two pencils in the pencil box. There are two pencils and a pen in the pencil box.

25、g no bus B. Being no bus C. There was no bus D. No busC考查了独立主格结构与并列句的关系。当在语句中有并列连词时，这就说明这是一个并列句，前后都是完整的句子，所以本题也就用了There was no bus。如果没有并列连词so，就说明它是独立主格结构，用There being no bus。(4) there be结构的时态与情态动词形式 there be结构的时态与情态动词形式是借助时态助动词或“情态动词be动词”的正确形式表达。 There is going to be a class meeting in our classroom this after
