1.B 根據(jù)句意,空處應該是否定意思,而 ACD選項都是肯定意思,所以B.
2.C 因為since+時間點或過去時態(tài)的句子時,翻譯為自什么時間以來,與現(xiàn)在有關,與現(xiàn)在完成時連用,所以C.
3.A.此句意思是 一些生物為了適應環(huán)境,能改變自身特征.環(huán)境應該用it 代替.
不知這解釋你是否滿意.有問題請繼續(xù)問.為什么改變自身特征不用themselves 或itself creatures不是復數(shù)嗎？so as to suit __________ 我認為此處意思是：為了適應環(huán)境 ，environment 應該用單數(shù)。 所以選了A。 suit oneself意思是：隨自己的意愿行事。我覺得在這不很合適。
