2道语法题
1."By considering that there are millions of gallons of freshwater",Florida environmentalists work to educate the public on the dangers of ground pollution.
文中引号处的用法是错误的.正确的是"Because millions of gallons of fresh water are".请问为什么?considering的正确用法是什么(什么时候才能用considering that ...
2.The name Transferware comes from a nineteenth-century technique "according to which" a pattern is engraved onto a copper roll,printed on tissue paper,and transferrid onto earthenware dishes.
文中according to which的用法是错误的.正确的用法是whereby.请问为什么?whereby的正确用法是什么?
这两题答案都不是死的,病句可以有多种改法.
1、句意要用“考虑到”,considering that ... 就可以了,By是多余的.
答案用Because只是使句子更加简洁而已.英语有使句子更加简洁的习惯.
considering that是【鉴于……而言,考虑到……】
eg. Considering that she is old, he sent her to a nursing home.
考虑到她已经老了,他送她去了疗养院.
2、句意应该是,“名字Transferware来自于一个19世纪的技术,用这项技术,可以往……上面刻上图案”.所以用whereby,用此,由此方法
whereby
adv.[古][疑问副词]根据什么;[关系副词]凭那个; 由此
a system whereby a new discovery may arise
由此可能产生新发现的体系
a plan whereby to escape
逃走的办法
whereby也可以用by which替代.但是不能是according to which.according to虽然有由于、根据的意思,但是偏原因,没有by的“手段、途径”的意思.
