　　1. Bno less than “与……同样(重要)”。全句意为: “放松休息, 就像新鲜空气、纯净水、清洁的食品一样, 是健康的身心所不可缺少的。”

　　2. Bto have a large fortune与to do well a bit of work…是并列不定式。另外，worth, worthy, worthwhile在用法上的区别是:(1)worth是介词, 后接动名词或名词，形成介词短语。接动名词时, 与主语是动宾关系，其形式是主动的，意义是被动的。如: The book is worth reading. (2)worthy是形容词, 置于be动词后或名词后面, 做后位修饰语, 其结构是: be worthy of doing sth., sth. is worthy to be done。(3)worthwhile是形容词，要与形式主语it并用：It is worthwhile to read the book.worth和worthy都不能用于这种结构。

　　3. Aone 指代前面提到的具有泛指含义的可数名词单数, 在该句中指代another nation, 句中属于泛指，可见B是错误的。such指代前面讲过的整个情况，多用作主语。that 指物时常用来指代不可数名词, 指代可数名词时具有特指含义。

　　4. Bwhether 引导名词性从句做主语, 谓语动词应为单数。另外，remain一般不用被动式, 所以B为正确选项。

　　5. C这是there be句型的异化形式，即there be 句型中还可以用be以外的不及物动词，如live, stand, exist, come, remain等。
