◆ Frank’s build, LIKE his brother, is broad and muscular.
上面的例句中用Frank’s build 和 his brother 进行比较，这在逻辑意义上不平行。所以正确的应该是：
◆ Frank’s build, LIKE his brother’s, is broad and muscular. 或者：
◆ Frank, LIKE his brother, has a broad and muscular build.
上面的例子中我们可以使用that 来代替build ，而如果是复数的话就要用those 来替换：
◆ Frank’s toes, LIKE THOSE of his brother, are short and hairy.
◆ I like to run through forests more than I enjoy walking through crowds.
上面的例子中run through forests 和walking through crowds 两个比较对象并不平行。To run 作为不定式，而walking 则是作为一个名词来使用，所以正确的可以写成：
◆ I like running through forests MORE THAN walking through crowds.
