WORDS
1.Sap
A style that consists of passive constructions will sap the reader’s energy.
If you describe something saps your energy,you mean you are weakened by it.
Eg.I was afraid the sickness had sapped my strength.
例子：The cold has sapped my strength so I am afraid I can not finish today’s reading task.
2.toss-up
Or is he perhaps—the opinion is open to argument—the best pitcher?Admittedly I don’t know. It’s virtually a toss-up.
If you describe something is a toss-up,you mean you don’t know exactly what the answer is.The either side is even.
Eg.It's a toss-up whether oil prices will go up or down over the days ahead.
例子：It’s a toss-up whether I go aboard or stay at home.
3.sprinkle
Like adverbs, they are sprinkled into sentences by writers who don’t stop to think that the concept is already in the noun.
If you describe something sprinkle with something,you mean it has a few of them throughout it and they are far apart from each other. 星星点点地分布

Men in green army uniforms are sprinkled throughout the huge auditorium.
4. dissimilar
it’s probably because you’re trying to make the sentence do more than it can reasonably do—perhaps express two dissimilar thoughts.
