VOA慢速英语:A Traditional Thanksgiving Meal, With Modern Shortcuts

over time随着时间的过去

例句：Bad habits are developed over time.
     坏的习惯随着时间慢慢滋生。

2. It tastes much sweeter than the starchier corn of the past.

much sweeter,much修饰比较级

3.The way Americans prepare for Thanksgiving has also changed. Economist John Anderson of the American Farm Bureau Federation says people look for ways to save time, though not everyone does.

not everyone部分否定

all，every，both，always等用于否定结构时不是全部被否定，而是表示其中的一部分被否定。而且英语多半将not置于谓语中。

例如：

All is not a gold that glitters.（即Not all that glitters is gold.）
闪闪发光物，未必尽黄金。

Every one cannot write novels.（即Not every one can write novels.）
不是所有的人都能写小说。

4.If you think about our food in general, not just Thanksgiving dinner, but our food products in general, there has been a tremendous move over the last twenty or thirty years toward more convenience products.

in general一般而言, 总的来说, 从总体上看

例句：The class are, in general, very bright.
      总的说来, 这个班级的学生都很聪明。
