掌握高频词汇，不再担心SAT考试难不难

　　很多考生担心SAT考试词汇量要求，课窝教育老师认为SAT考试背单词也并非只是单纯的死记，大家需要结合SAT真题等理解SAT词汇的运用，那么备考SAT该如何做呢?一起先来学习高频词汇吧~

　　在可汗阅读历史类篇章Benjamin 于1787年的Constitutional Convention上发表的演讲中有出现，如下：

　　For having lived long, I have experienced many instances of being obliged by better information or fuller consideration, to change opinions even on important subjects, which I once thought right, but found to be otherwise.

　　在文学类篇章Jane Austin 的NorthAnger Abbey中有如下句子：

　　They saw nothing of Mr. Allen; and after looking about them in vain for a more eligible situation, were obliged to sit down at the end of a table, at which a large party were already placed, without having anything to do there, or anybody to speak to, except each other.

　　/在这两个句子中，都有一个共同的词组feel / be obliged to do sth. 该词组意为被迫做某事

　　obliged 还有一个重要意思，就是感激的。

　　eg. I am much obliged to you for helping us.

　　补充一个意思：

　　oblige有help，帮忙之意。

　　eg. I'd be glad to oblige.

　　eg. Would you oblige me with some information?

　　在2016年北美十月真题的社会学篇章David Rotman的“How Technology is Destroying Jobs”中有个句子：

　　MIT business scholars Erik Brynjolfsson and Andrew McAfee have argued that impressive advances in computer technology—from improved industrial robotics to automated translation services—are largely behind the sluggish employment growth of the last 10 to 15 years.

　　又如可汗阅读文学类篇章Nathaniel Hawthorne的The House of the Seven Gables中有如下句子：

　　He was as yet invisible; the sluggishness on Colonel Pyncheon's part became still more unaccountable, when the second dignitary of the province made his appearance, and found no more ceremonious a reception.

　　另外，在北美六月的Essay考试篇章Raise The Minimum Wage中也出现过：

　　But in California, as in most of the United States, growth has been sluggish.

　　第一和第三句都和经济有关，可见该词在形容经济发展缓慢时是个常用高频好词。意为缓慢的。

　　第二句形容人的行动迟缓，懒散。意为行动迟缓的，懒散的。

　　该词在柯林斯词典中的英文解释如下：

　　You can describe something as sluggish if it moves, works, or reacts much slower than you would like or is normal.
