A.increased B.would contracted C.has increased D.had increased
3.Some living creatures can change certain features of their environment so as to suit _______.
A.it B.itself C.them D.themselves
1.B 根据句意,空处应该是否定意思,而 ACD选项都是肯定意思,所以B.
2.C 因为since+时间点或过去时态的句子时,翻译为自什么时间以来,与现在有关,与现在完成时连用,所以C.
3.A.此句意思是 一些生物为了适应环境,能改变自身特征.环境应该用it 代替.
不知这解释你是否满意.有问题请继续问.为什么改变自身特征不用themselves 或itself creatures不是复数吗？so as to suit __________ 我认为此处意思是：为了适应环境 ，environment 应该用单数。 所以选了A。 suit oneself意思是：随自己的意愿行事。我觉得在这不很合适。
