PETS二级考试猜词技巧(2)
如何猜词，看这里。
③对比法，即通过同义、反义或转折词的关系来确定词义, 如:
She is usually prompt for all her class, but today she arrived in the middle of her first class.
but一词表转折，因此but 前后的意思正相反。后半句的意思是她今天"第一节上了一半才来"，因此反向推理，可得出她平时一向"准时"的结论。
④构词法（前缀、后缀、复合、派生等），即运用词根、词缀的意义判断词义，如:
Perhaps, we can see some possibilities for next fifty years. But the next hundred?
possibility 是 possible 的同根名词，据此可以判断定 possibility 意思是"可能性"。
⑤因果法，即运用因果关系和因果词如so, because, therefore, hence等来判断词义，如:
The lack of movement caused the muscles to weaken. Sometimes the weakness was permanent. So the player could never play the sport again.
从后面的结果"永远不能再运动"中，可以推测 permanent 的意思为"永远的，永久的"。
