　　3、Idleness is the root of all evils.

　　4、He was ashamed to have made the mistake.(=He was ashamed that he had made the

　　mistake. =He was ashamed because he had made the mistake.)

　　除了上述例句外，英语中还有很多或易或难表达原因结构。我们在进行写作训练时候，不能满足于一知半解，要讲究书面语言正确性和准确性。比如，because是最常用引导原因从句连词，语气最强，表示直接原因，若because置于句首，后面主句不能再用so。用as引导原因从句语气较弱，所说明原因是附带，而since表示原因暗示着是稍加分析之后才能推断出来原因。

　　四、否定结构

　　评议与分析：

　　例句1选自96年1月四级考生作文，例句2选自92年1月六级考生作文。例句1 错误在于该考生混淆了need作为情态动词和作为普通动词用法。need作为情态动词时，主要用于否定句，后面动词不带to, needn't worry，作we谓语。need作为实意动词时，可用于肯定句、否定句和疑问句，don't need to worry 中to worry作don't need宾语。例句2错误在于该考生混淆了too和either区别，这两个词都表示“也”意思，但是在英语中too, also只能用于肯定句，而either只能用于否定句。
