托福写作词汇each VS every

　　I want them each to be happy.

　　She kissed them each on the forehead.

　　I bought the girls each an ice-cream.

　　She sent them each a present.

　　(BUT NOT I helped them each OR I wrote to them each.)

　　5.one each etc

　　Each can follow a noun object in sentences that say how much/many ofsomething each person gets.

　　They got $20, 000 each when their mother died.

　　I bought the girls two ice-creams each.

　　A similar structure is used in giving prices.

　　They cost $5.50 each.

　　6. each without a noun

　　We can drop a noun and use each alone, if the noun has already beenmentioned, but each one or each of them is more common in an informal style.Note that a following verb is normally singular.

　　I’ve got five brothers, and each (one/of them) is quite different from theothers.

　　7.pronouns

　　When a pronoun or possessive is used later in a clause to refer back toeach + noun/pronoun, the later word can be singular (more formal) or plural(less formal)

　　Each girl wore what she liked best. (more formal)

　　Each student wore what they liked best. (less formal, “they” is wrong inETS’s eyes.)

　　Each of them explained it in his/her/their own way. (“their” is wrong inETS’s eyes)

　　二.Each and every: the difference

　　1.Each with two or more; every with three or more

　　Each and every are both normally used with singular nouns. Each can be usedto talk about two or more people or things; every is normally used to talk aboutthree or more.

　　The business makes less money each/every year. (NOT….each/every years.)

　　She had a child holding on to each hand. (NOT…every hand.)

　　Note Every (which is normally used with singular nouns) can be used beforeplural expressions in measurements of frequency. For example: every two years,every tree steps.

　　I go to Hong Kong every six weeks.

　　2. difference of meaning

　　In many cases, both each and every can be used without much difference ofmeaning.

　　You look more beautiful each/every time I see you.

　　But we prefer each when we are thinking of people or things separately, oneat a time. And every is more common when are thinking of people or thingstogether, in a group. (Every is closer to all.) Compare:

　　Each person in turn went to see the doctor.

　　He gave every patient the same medicine.

　　We do not use each with words and expressions like almost, practically,nearly or without exception, which stress the idea of a whole group.

　　She’s lost nearly every friend she had. (NOT…nearly each friend…)

　　0208-36: Almost (every) the hereditary (material) of (an individual)organism resides (in the) chromosomes.

　　The correct answer is: every -----> all.

　　It\'s for sure that “every” is wrong in the sentence, but if “every”------> "each of", “ almost each of the…” is still wrong.
