　　2. each of

　　We use each of before a pronoun or a determiner (for example the， my， these). The pronoun or noun is plural.

　　each of us/you/them

　　each of + determiner + plural noun

　　Each of us sees the world differently.

　　I write to each of my children once a week.

　　3. each in mid-position

　　When each refers to the subject， it can go with a verb in mid-position， like all， both and some adverbs. In this case plural nouns， pronouns and verbs are used.

　　auxiliary verb + each

　　are/were + each

　　They have each been told.

　　We can each apply for our own membership card.

　　You are each right in a different way.

　　each + other verb

　　We each think the same.

　　The plans each have certain advantages and disadvantages.

　　4.position with object

　　Each can follow an object (direct or indirect) as part of a longer structure.

　　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 of something 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 been mentioned， 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 the others.

　　7.pronouns

　　When a pronoun or possessive is used later in a clause to refer back to each + 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 in ETS’s eyes.)

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