2018年首场SAT考试就在明天，3月的SAT考试首次在亚洲设置考场既让人兴奋又让人紧张：终于可以不用舟车劳顿参加3月考试；3月首场亚洲考试会不会当小白鼠？为了给同学们考前一颗定心丸，TD特地给大家准备了语法备考锦囊，助你变身套路王，决胜SAT。
一、undermine,contradict通常都不选
以2016.3US第11题为例：
This lifestyle also gives them the abilityto search farther and in more diverse locales than other organisms in the huntfor food, reproductive opportunities, and optimal environmental conditions.
At this point, the writer is considering adding the followingsentence.
Because conditions vary both form region toregion and over time within a given region, not all environmental conditionsare equally optimal.
Should the writer make this addition here?
A. Yes,because it makes an important exception to the claim in the previous sentence.
B. Yes,because it highlights the difficulties of living both in the rest of theparagraph.
C. No, becauseit contradicts information presented in the rest of the paragraph.
D. No, becauseit provides a weak conclusion to the passage by digressing from the main point.
全文主要在讲mudskippers弹涂鱼的双呼吸模式对于其生存的帮助，这句话与文章内容无关，因此要删掉，No的两个选项中C有contradict，排除，答案为D。
以2016.3US第15题为例：
The illusion is a powerful one, but theexhibit offers more than just fantasy: careful attention to these remarkableitems reveals the physical realities behind the legends of medieval Europe.
At this point, the writer is considering adding the followingsentence.
In fact, the museum has an extensiveselection of items from around the world, from early American muskets to theskill, horsehair, and leather uniforms of Japan’s Edoperiod and the Turkish curved swords known as scimitars.
Should the writer make this additionalhere?
A. Yes,because it provides additional relevant information about the items displayedin the gallery.
B. Yes,because it highlights the extent of the museum’scollection of arms and equipment.
C. No, becauseit distracts from the passage’s focus on the armor ofmedieval Europe.
D. No, becauseit undermines the writer’s claim that the exhibitreveals historical realities.
全文讨论核心内容是armor，因此该句提到的博物馆的一系列展品属于无关信息，因此删掉。D有undermine排除，答案选C。
2016.12US第33题为例：
These studies have shown that floating islands are successful at curbing the effects of polluted runoff.
At this point, the writer is considering revising the underlined portion as follows.
runoff and that more communities should embrace this practical solution to the problem of our diminishing wetlands.
Should the writer make this revision here?
A. Yes,because it clarifies the environmental problem that has made the development off loating islands so important.
B. Yes,because it strengthens the conclusion of the passage by recommending a courseof action that follows logically from the argument.
C. No, becauseit introduces a new perspective on floating islands that does not belong in the concluding sentence of the passage.
D. No, becauseit assumes that the reader is directly affected by this issue.
题目问该非完整句是否要添加，因为是非完整句，当然要选yes。因为非完整句通常都会对文章中已经出现的信息进行解释或者补充，所以一般都是有用信息，因此留下。本题A选项说该句清楚表述了使得发展浮岛变得如此重要的环境问题，但是这句话并没有说具体什么环境问题，因此选择B。
再来看2017.3US第43题
He rallied sixty four prominent Americans to sign a petitionasking US government to award him unlimited funds to build broad acre.
At this point, thewriter is considering revising the underlined portion as follows.
Americans, including artist Georgia O’Keeffe,philosopher John Dewey, and playwright Thornton Wilder
Should the writer make this revision?
A. Yes,because it strengthens the claim made in previous sentence by naming some ofWright’s supporters.
B. Yes,because it provides insights into what kinds of professions were considered tobe influential in Wright’s day.
C. No, becauseit does not demonstrate that the people listed were prominent during Wright’stime.
D. No, becauseit does not list any prominent architects as Broadacre supporters.
增加的部分是非完整句，留下。AB中选择。美国名人的列举就是为了对之前提到的Americans具体解释，所以选择A。
以2016.11Asia第23题为例：
Software allows text and other visual artifactsto be archived andsearched. They can also be adapted, and interactive programs help readersengage with texts and with each other in new ways.
Which choice most effectively combines the sentences at theunderlined portion?
A. archived andsearched; while works can also be adapted
B. archivedand searched, and besides being adapted,
C. archived,searched, and adapted; however,
D. archived,searched, and adapted, and
该题只把两句话交界处的几个词划线archived ... and, 因此根据套路选最短，D符合。当然，需要把选项带入原文验证语意是否符合要求。
再来看一道2016.12US第25题
Floating islands are wetland replicas. They are constructed on basesof durable, buoyant materials.
Which choice most effectively combines thesentences at the underlined portion?
A. replicas;these are constructed
B. replicasconstructed
C. replicas:these islands are constructed
D. replicas;they constructed them
划线部分仍然处于两句话交界，最短选项为B。语意符合原句，constructed on修饰replicas。
看完了以上内容，大家一定意识到应考技巧很重要，但是，考场心态也不容忽视。在这里严肃提醒大家：考试时高度集中精力。
考试过程中，同学们会不自觉得陷入这样一种思维中：阅读部分难度大，我一定要特别专注。65分钟的阅读考试结束后，进入语法部分，同学们可能会默默长舒一口气，精神上容易放松下来，语法部分不像之前那样大脑活跃且紧张。但是！大错特错！语法知识点考得非常细节，并且语法更有可能冲击高分，因此要更专注！语法考试过程中要不断给自己“要专注”的心理暗示。
同学们考前要记得过一遍错题集，熟记小妙招，预祝大家取得理想成绩！
