to protect the environment for future generations.解析：句意：为了子孙后代，当地政府在保护环境方面所能做的事情是显而易见的。It为形式主语，_ the local government can do to protect the environment for future generations是真正的主语，该主语从句缺少宾语，且表示物，故填what。2New technologies have made _it_ possible to turn out new products faster and at a lower cost.解析：考查it作形式宾语。3All possible means _have_been_taken_(take) to

I am sure he will _in_ time.解析：句意：经理想要看到公司的改变，我确信他迟早会看到的。in time“及时；最后，迟早”，符合题意。12It remains to be seen _whether_ the newly formed committees policy can be put into practice.解析：本题考查名词性从句。句意：那仍然得看新形成的委员会政策能否付诸实践。It在此为形式主语，故seen后为真正的主语从句，又由remains to be seen可知存在不确定的意思，所以用whether是否。13The top leaders of the two countries are holding talks in a _friendly_(friend)
