事實(shí)細(xì)節(jié)題。本題察看對(duì)復(fù)雜句的理解。第

4段第

1句指出了答案。

from是對(duì)

resistantto

的同義取代。3.[B]

推理判斷題。本題察看對(duì)長(zhǎng)句的理解。最后一段第

2句中的

B為正確選項(xiàng)。其余選項(xiàng)固然都是昆蟲假裝的目的，但都與假裝成自然物體沒關(guān)。4.[D]推理判斷題。本題察看對(duì)含有分詞構(gòu)造的理解。依據(jù)第2段倒數(shù)第2句中的useful及分詞構(gòu)造pollinating可推測(cè)昆蟲對(duì)植物的生長(zhǎng)有好處。選項(xiàng)A、B、C中都有any,過于絕對(duì)。由第3段第2、3句可知選項(xiàng)A不對(duì)。文章雖在開頭指出昆蟲存活的.年月久遠(yuǎn)，但全文未提到它是存活時(shí)
