trail和trace的区别?

英语沙龙您好,我想请问您几道单选题
1.The gang has escaped without any__.
A.traits B.traces C.tracks D.trails
我查过字典,四个都有踪迹的意思,应该怎样区别呢?答案(B)
2.Thomas edison considered genius to be__one percent inspiration and ninety-nine percent perspiration.
A.constituded in B.composed of C consisted of D.comprised in
我觉得B和c都可以
●
Trait指特点、特征、特性.Trace指 mark,track,sign,etc.showing what has existed or happened,即"曾经存在或发生的事所留下的痕迹、踪迹",也就是我们所讲的抽象意义上的踪迹、痕迹.Track和trail两个词均表示人用肉眼看得见的踪迹、痕迹,其中track尤指车辆、行人、运行经过后留下的足迹、痕迹.）
下面再给你举一个例子：
Sorrow and disappointment left their ____ upon his character.
A.tracks B.traits C.traces D.trails
答案：C
第二题应该选B.虽compose和consist都有"组成、构成"之意,可两者在句法的构成上却是不同.前者一般用作"be composed of",而后者则是"consist of"(主动形式).
如：Water is composed of hydrogen and oxygen.
The house consists of six rooms.
