Inflation has made many Americans reevaluate their assumptions about the future; they still expect to live better than their parents did, but not so well as they once thought they could.
=Inflation/ has made many Americans/ reevaluate their assumptions about the future/; they still expect to live better/ than their parents did/, but not so well as they once thought they could.
#通货膨胀/已经使很多美国人/重新定位他们对未来的期望/;他们仍然期望过的更好/比他们的父母/但并没有他们想象的那么好。
*这个句子不长，意思也很简单。但注意句中的两个比较：一个是live better than，就是通常的比较级，容易理解;另一个是not so well as，as well as 是和…一样好，加个not表示不如…好，而不是和…一样不好。
Europeans have long known that eating quail sometimes makes the eater ill, but only recently has it been established that the illness is caused by a toxin present in the quail’s body only under certain conditions.
=Europeans have long known/ that eating quail sometimes makes the eater ill/, but only recently has it been established/ that the illness is caused by a toxin/ present in the quail’s body/ only under certain conditions.
#欧洲人很早就知道/吃鹌鹑有时使得吃的人得病/，但是直到最近才知道/这个病是有一种毒素引起的/存在于鹌鹑的体内/只有在某些条件下。
*这句话比较简单，前后意思相对，句子的重心在后面。有个难点but only recently has it been established，不要想语法，只要考虑内容，“最近才明白”，并不难理解。
