I quite agree to the suggestion that we should recycle these textbooks. For one thing, recycling textbooks can save a lot of natural resources, which is beneficial to our environmental protection and sustainable development. For another, senior students may have made plenty of useful notes on the pages. They are of great help to those textbook users, who may benefit and improve a lot by consulting the recycled textbooks. A lot of precious time and energy are saved.

　　From my point of view, much emphasis should be laid on the environmental protection. It’s essential we have the awareness of recycling textbooks in good condition instead of throwing them away. Saving resources and protecting what can be recycled and reused is the responsibility all of us should shoulder.

　　语境的判断在许多情况下需借助个人常识来判断, 所以考生在做题时应充分结合自己所具备的常识进行合理推测, 如车在转弯时车速要放慢, 人累了就要休息, 这都是常识。不过若是作者用了but, however之类表示转折的词语, 情况则可能与已知常识完全相反。
