阅读理解中不可避免地会遇到一些生词(有些是熟词生义)，疑难语句。遇到这些问题，我们可用下面几种方法解决：

技巧1：根据同义词或反义词来判断

如：Tom is lazy but his brother is industrious.

该句中but表示转折，就暗示了lazy和industrious是一对反义词，由此可知in dustrious意为“刻苦的、勤奋的”。

技巧2：根据定义和释义来 推测

如：She is studying g lauc oma，a kind of disease on the eyes.

我们可能猜不出glaucoma的确切 词义，但通过后面的解释可知道glaucoma(青光眼)是一种眼睛疾病。

技巧3：根据常识来推测

如：Water usually boils at 100 centigrade.

众所周知，水的沸点是100摄氏度，由此不难判断出centigrade的意思是“摄氏度”。

技巧4：运用构词法进行猜测

如：The colors of Hawaii in summer are unforgettable.

forget意为“忘记”，un为否定前缀，因此unforgettable就是“令人难忘”之意。]
