今天小编要和大家探讨的问题是：托福阅读遇到生词要如何应对?那么面对这样的情况，各位考生要怎么做呢?快来听小编讲一讲吧!
应对技巧2：从上下文中找线索
At night, the solar energy (stored as vast quantities of heat in city buildings and roads) is slowly released into the city air. Additional city heat is given off at night (and during the day) by vehicles and factories, as well as by industrial and domestic heating and cooling units. The release of heat energy is retarded by the tall vertical city walls that do not allow infrared radiation to escape as readily as does the relatively level surface of the surrounding countryside. The slow release of heat tends to keep nighttime city temperatures higher than those of the faster-cooling rural areas.
The word "retarded" in the passage is closest in meaning to
A. disguised
B. added to
C. made possible
D. slowed down
应对托福阅读词汇题中陌生词汇的第二个技巧是从生词本身所在的上下文中寻找线索来进行突破。以上面这道题为例，retarded出现在这个句子里：
The release of heat energy is retarded by the tall vertical city walls that do not allow infrared radiation to escape as readily as does the relatively level surface of the surrounding countryside.
很显然这是个大家比较头疼的长难句，先来简化一下，变成：
The tall vertical city walls are doing something to the heat energy because they do not allow infrared radiation to escape.
总而言之就是city wall对heat energy做了点什么以防止radiation escape。这个句子里比较有意思的就是do not allow，现在再回头去看题目选项给出的这些词汇，added to和made possible显然在意思上都是和not allowed有冲突的，可以先排除掉，剩下的diguised不好判断，heat energy能不能被disguised不好说，但放在这里显然意思上不太搭，跟整个句子关系不大。这样一来选项D显然看上去就顺眼多了，不让infrared radiation逃脱所以要slow down一下heat energyd的释放也是比较符合逻辑关系的。正确答案也的确就是D。
应对技巧3：词性判断排除法
Several dinosaur fossil localities preserve coprolites. Coprolites yield unequivocal evidence about the dietary habits of dinosaurs. Many parts of plants and animals are extremely resistant to the digestive systems of animals and pass completely through the body with little or no alteration. Study of coprolites has indicated that the diets of some herbivorous dinosaurs were relatively diverse, while other dinosaurs appear to have been specialists, feeding on particular types of plants. The problem with inferring diets from coprolites is the difficulty in accurately associating a particular coprolite with a specific dinosaur.
The word "unequivocal" in the passage is closest in meaning to
A. deniable
B. unambiguous
C. unclear
D. largely
最后一种应对词汇题生词的技巧其原理来自于做选择题时比较经典的排除法思路。而应用到词汇题上，比较容易切入的一个排除点就在于词汇本身的词性了。来看上面这道例题，选项的4个词汇里有一个明显画风不一样词性不对路的词，就是选项D的largely，妥妥的副词。而uneuivocal本身很明显是一个形容词。所以选项D就可以先行排除掉了。之后再看剩下的3个选项，deniable和unclear意思是比较相近的，都有不确定的含义在里面，而unambiguous的意思则正好相反，是毫不含糊，明确。那么正确选项应该就是B了。
