because of ,due to , owing to , on account of和thanks to 的用法比较

这一词都表示“由于”的意思，在使用时应该注意以下区别：1．because of意为“由于，因为”，强调因果关系，在句中仅作状语，修饰句中的一部分，与其他成分不用逗号隔开。如：We must not get discouraged because of such a minor setback．

我们决不可因为这样一个小小的挫折而灰心丧气。2．owing to与because of一样，也强调因果关系，除作状语外，也可作表语。作状语时修饰整个句子，可在句首或句末，用逗号隔开。如：

They decided to cancel the flight，owing to the storm．

由于这场暴风雨，他们决定取消这个航班。

His death was owing to an accident．他死于一场事故。3．due to引出造成后果的原因，在句中作表语、状语和定语。作表语和状语时与owing to同义，作状语时，一般不与其他成分隔开。不用于句首。如：

This accident was due to（owing to）his careless driving．

这次车祸是由于他开车疏忽大意造成的。

He arrived late due to（owing to）the storm．由于暴风雨他来晚了。

Mistakes due to carelessness may have serious consequences．

由于疏忽大意造成的错误可能带来严重的后果。

4．on account of与because of，owing to同义，但语气较为正式。可作状语、表语，不作定语。如：

He could not come on account of his illness．他因病不能前来。

That was on account of lack of exercise．那是由于缺乏锻炼。5．thanks to表示“幸亏，多亏”多用于表达正面意思，相当于感谢，在句中作状语和表语。

如：Thanks to your advice，much trouble was saved．多亏你的建议，减少了许多麻烦。

5.tough

1）The wire is tougher than that. (坚韧的，不易磨损的）2）You need to be tough enough to survive in the jungle.（坚忍不拔的，吃苦耐劳的）

3）a tough criminal（粗暴的，凶暴的）
