1. 表特指
所谓表特指，就是说此时的what 在用法上大致相当于the。如：
What money I have will be yours when I die. = The money I have will be yours when I die. 我一死我的钱就都给你。
What possessions I have are yours.=The possessions I have are yours. 我的所有的财产都是你的。
2. 表“微量”
有时不仅表特指，而且还表“微量”，即含有“量不多”之意。如果将“特指”和“微量”结合起来，该结构的意思就是“虽不多，但全部”，有时可译为“仅有”。如：
What ideas he has are his wife’s. 他仅有的一点想法都是他妻子的。
What friends she has are out of the country. 她有的那些朋友全在国外。
这类“what+名词”结构并不是总具有“微量性”，即有时有，有时没有。如果要想明确或强化这种微量性特点，我们可以该结构的名词前加上表示微量的修饰语few(用于复数名词前)或little(用于不可数名词前)。如：
What few friends she has are out of the country.=The few friends she has are out of the country. 她仅有的几个朋友都在国外。
What little free time he had was spent with the family.= The little free time he had was spent with the family. 他仅有的一点空余时间都是与家人在一起度过的。
