马上就要考试了，让大家背的2300个核心词汇记得怎么样了？当然，如果在考场上忘了也要有对策：生词如果不影响做题就直接跳过，如果影响做题的话就教大家下面几种方法去推测！大家赶快都来过一遍！
1.词根词缀
用词根、前缀、后缀推断生词的含义、词性或情感方向。
倘若你在完型中遇到这两道题：
①anonymity is also behind the explosion of cyber-crime...Can privacy be preserved while bringing safety and security to a world that seems increasinglylawless ?（-less是否定后缀，表示没有什么什么的，此处表示没有法律的、无法无天的，与上文的crime对应）
②Such visions are based on the downsides of being unemployed in a society built on the concept of employment.（downsides是合成词，down表示负面方向，sides是方面，因此该词的意思是不利方面。）
下面给大家整理最常用的一些词根、后缀及前缀：
| 属性 | 特征 | 含义 | 举例 |
| 词根 | flect, flex | 弹性 | reflect/flexible 反映、回想/柔软的、灵活的 |
| part | 部分 | party/participate 派对、党派/参加 | |
| pict | 画 | depict/picture 描述/图片 | |
| scribe | 写 | describe/subscribe 描述/订阅 | |
| sequent | 顺序 | subsequent/consequence 随之而来的/结果 | |
| graph | 图画 | photograph/telegraph 照片/电报 | |
| pose | 摆放 | expose/compose/impose 暴露、使接触/组成/施加 | |
| struct | 结构 | construct/infrastructure 建造/基础设施 | |
| rupt | 断裂 | disrupt/interrupt/bankrupt/erupt 破坏/中断/破产/喷发 |
| 属性 | 特征 | 含义 | 举例 |
| 后缀 | -ee | 人的职业（被动） | employee/trainee 雇员/培训生 |
| -er/or/ist | 人的职业（主动） | employer//instructor/specialist 雇主/导师/专家 | |
| -ment/ion/ness/ance | 名词 | encouragement/adaptation/ willingness/importance 鼓励/适应/意愿/重要性 | |
| -ous/al/ble/ful | 形容词 | anxious/critical/ responsible/grateful 焦虑的/批判的/ 负责的/感恩的 | |
| -ly | 副词 | fortunately/undoubtedly 幸运地/毋庸置疑地 |
| 属性 | 特征 | 含义 | 举例 |
| 前缀 | pre- | 之前 | preview/precondition 预习/先决条件 |
| post- | 之后 | post-postwar/postgraduate 战后/研究生 | |
| im/in- | 向内 | import/invasion 进口/侵略 | |
| out- | 向外 | outside/outbreak 外部的/爆发 | |
| super- | 上 | supermarket/superficial 超市/肤浅的 | |
| re- | 再次 | review/reunion 回顾/重聚 |
2.根据逻辑连接词推测
比如在阅读中遇到这道题：
Unlike so-called basic emotions such as sadness, fear, and anger, guilt emerges a little later, as well as a child’s growing grasp of social and moral norms.
Researchers think that guilt can be a good thing because it may help__C foster a child’s moral development.
（即使句中有许多生词，仅根据句中的逻辑联系词unlike、such as、and、as well as，我们可以得出：sadness、fear和anger同类都属于emotion，a child’s growing grasp of social and moral norms和前文的later一致，即可整理出句子的结构：不像......guilt later，child’s moral norms也是）
| 逻辑关系 | 连接词 |
| 对立 | but / however / yet / nevertheless / nonetheless（然而，但是）； Although / Though / while / despite / in spite of / even though / even if（尽管）； instead / rather than / while / whereas / unlike / on the contrary / by contrast / 比较句（than）前后 |
| 并列 | and / also / similarly / likewise / meanwhile / as well as / either…or.../ neither…nor… |
| 因果 | because / for / as / since / duo to / owing to / in that / now that / as a result of（因为）; so / thus / therefore / hence / as a result / lead to（所以） |
| 举例 | for example / for instance / such as |
| 递进 | not only...but(also)..., what's more, moreover, furthermore, more importantly, what's worse, worse still, besides, in addition 比较级 |
| 总结 | Overall, to sum up, to summarize, to conclude, in conclusion, on the whole, in a word, in short, briefly, all in all |
3.根据上下文推测
比如翻译里的一句话：
“I had so much anxiety that I would wake up in the middle of the night and stare at the ceiling. I had no money and needed the job. ”
双引号表明这是一段自述，在描述一个具体的情景。
① 如果不认识anxiety，可先放，根据后文提到的“我没有钱，我需要工作”，表明这是一个负向词，那么可以尽量翻成“难过/不安/焦虑/有压力”等。
② 如果不认识stare 和 ceiling，可根据介词at表明在某物上、对着某物。根据前文，“我在半夜醒来”，可推断，只能对着天花板看。
4.根据介词推测
比如在完型中遇到这样的题：
Weighing every other week allows me to observe and _____ any significant weight changes. A approve of B hold onto C account for D depend on
（该题属于完型中的短语考察，即使不知道选项短语的意思，根据介词也可推出：of表示从属、.....的，onto表示在......上，for引导因果，on表示....之上。and表示前后并列，and前说明weighing 让我去observe，后文也一定表示weighing的作用，所以解释changes改变的原因，选C。）
5.机智飘过
在翻译里如果遇到一个必须翻译且无法根据上下文推断的题目，比如：
He ticks “astronaut” but quickly adds “scientist” to the list and selects it as well.
实在不知道astronaut的意思的时候，就这样翻使句子尽量通顺：他选了一个职业，但很快加了“科学家”到列表中并也选了它。
