考点1：时间进程
TIME [singular] a period of time or processduring which something happens.
during/in/throughout/over the course of something
在OG1 - 2 Money Can’t Buy Love: Asymmetric Beliefs aboutGift Price and Feelings of Appreciation这篇文章中，有这么一段：
Thenotion of gift-givers and gift-recipients being unableto account for the other party’s perspective seems puzzlingbecause people slip in and out of these roles every day, and, in somecases, multiple times in the course of the sameday.
送礼方和收礼方不能很好的换位思考实在让人不解，毕竟人们每天都在这两个角色间切换，有时同一天还要切换好几次。这里面的course就指的是在同一天这段时间里。
in the course of
在…之中;在…期间
同时大家也经常会在题目当中读到，这样的题干：
During the course of the first paragraph, the narrator’sfocus shifts from:
这种考察整体结构的题目中的course也是取这个意象。
during the course of
在…的过程中
考点2：行动:行为方式
ACTIONS [countableusually singular] an action or series of actions that you couldtake in order to deal with a particular situation
OG 2 -1小说TheProfessor第八问选项中出现A) contrastingtwo hypothetical coursesof action. 对比两种假设行为，这里面提到的所谓coursesof action就是行为方式的意思。
course of action
行动过程;做法
3.方向：航向;行动方向
DIRECTION [countableusually singular, uncountable] the planned direction taken by a boat or plane toreach a place
OG 3 - 1小说The Schartz Metterklume Method第二问词汇题，
Inline 2, “turn” most nearly means
A) slightmovement.
B) changein rotation.
C) shortwalk.
D) course correction
很多同学可能会觉得D选项好奇怪，为什么要纠正“课程”呢?其实不然，这里面的course就取得方向的意思。大家想一想turn是不是也暗含了改变方向呢?所以这个也是一个很强烈的干扰项。
course correction
纠正路线;航线修正
再来看Practice7 - 3 , Why birds fly in a V Formation，阅读文本：
Theyplan to investigate how the animals decide whosets the course and the pace,and whether a mistake made by the leader can ripple through the restof the flock to cause traffic jams.
他们计划调查动物如何决定谁设定路线和速度，以及的错误是否会使其他鸟群遭殃，造成交通堵塞。

4.教育：课程;讲座

Practice 7 - 5 , Howthe Higgs Boson Was Found，阅读文本：
Infact, in a graduate courseI took that covered what’s known as the StandardModel of ParticlePhysics (the quantum equations physicists have assembledto describe the particles of matter and the dominant forces by which theyinfluence eachother), the professor presented the Higgs field with suchcertainty that for a long while I had no idea it had yet to beestablished experimentally.
a graduate course
研究生课程
► 注：course之后不跟’of’, 不能说 a course of Business Studies’. 应该是‘a course in Business Studies’。
5.发展：进展;进程
DEVELOPMENT [singular] the usual or natural way thatsomething changes, develops, or is done.
take/run its course (=develop in theusual way and reach a natural end)
PSAT 2 - 3，Yellowstone Wolves Boost Berry Diet forGrizzlies, 阅读文本：
“We’re inthe early stages of this ecosystem recovery. This is what we call passiverestoration,” Ripple said. “We put the wolf back in and then we let nature takeits course.”
“我们正处于生态系统恢复的早期阶段。这就是我们所说的被动恢复，“Ripple说。 “我们把狼放回来，其余的就顺其自然。”
take its course
顺其自然;任其自然发展
除了以上出现的这五种，course还有菜肴(MEAL)，比赛(SPORT)，江河(RIVER)，医疗(MEDICAL TREATMENT)，墙壁(WALL)的意思，瞧瞧，一词多义到这种程度，因此背单词一定不能局限在单词书里，还要通过大量阅读，结合上下文，掌握同一单词在不同语境中的不同含义，这正是新SAT和GRE强调的“Words Within the Context”!
