It's a waste to cut　　 lots of trees for chopsticks every year．

There's no doubt that　　 is the coldest season of the year in China．

The traffic was so heavy this morning that I was nearly　　 for school．

I fell in love　　 the Science Museum of Jilin Province the first time I visited it．

The weather report says there will be a strong wind today．Be sure to　　 all the windows．
