1．A is Bwhat C is to D．
1） Water isto fish what air is to man（水對魚的關(guān)系就象空氣對人的關(guān)系一樣.）
2）Ten is tofive what eight is to four．（10比5等于8比4）
2．What C isto D,A is to B．
l）What foodis to the body,a book is to themind.（書籍對于心靈猶如食物對于身體.）
2）Whatthegun is to a fighter,the pen is to awriter．（作家的筆猶如戰(zhàn)士的槍.）
3．What C isto D,that A is to B．
