1.原句：Snakes come near the house now and then and they seem to have made _____________, their home here,not far from the walnut tree. 它们好像在这儿安了家，离核桃树不远。 句型：Sb. seems to do...=It seems that sb. do好像 ⑴ 他好像什么都知道。 He seems to know everything.=It seems ____________________________________ that he knows everything. _____________________________. ⑵ 他好像已在这个公司工作多年。 He seems to have worked=It seems that _____________________________________ he has worked in the company for several years. _____________
“There + seem to be +名词”,其中to be 可省略。 seem 的单复数形式要根据后面作主语的名词的单复数 形式而定。例如： There seems no need to wait any longer. 看来没有再等的必要了。 There seem to be a lot of things to do . (=It seems as if there were a lot of things to do.) 从课文中找到具有这一结构的句子： The first thing I did was to see if there were any products that might help me, but there only seemed to be powders designed to kill snakes.
结构分析：全句是一个由but连接的并列句， 前一分句的主干是the first thing was to see...; (that)I did是定语从句，修饰the first thing; 宾语 if引导的从句作see的 ⑴ ______,在这个 ⑵ 宾语 ______ 从句中， that might help me是定语 从句，修饰products;but后的分句中， designed to kill snakes是过去分词短语作 ⑶ ________ ,修饰powders。 定语
