第一個(gè)：He went to the United States.
第二個(gè)：He has gone to the United States.
第三個(gè)：He is going to the United States.（也可以說(shuō)He will going to the United States）
be going to的意思是 打算（還未決定）,will的意思是 將（已經(jīng)決定）,根據(jù)需要選用不同的句子
區(qū)別,我分開來(lái)說(shuō)吧：
先說(shuō)have gone to,have been to
1) have gone to意為“到某地去”,說(shuō)話時(shí)該人不在現(xiàn)場(chǎng),一般不用第一人稱、第二人稱代詞作句子的主語(yǔ).如：
—Where is Jim?———吉姆在哪里?
—He has gone to England．———他去英國(guó)了.（尚未回來(lái)）
Mr Wang isn't here．He has gone to Qingdao．王先生不在這里.他去青島了.
2) have been to意為“曾經(jīng)去過某地”,現(xiàn)在已不在那里了,現(xiàn)在回來(lái)了,后可接次數(shù),如once,twice,three times等,表示“去過某地幾次”,也可和 just,never,ever等連用.如：
My father has been to Beijing twice．我父親去過北京兩次.
I have never been to the Great Wall．我從未去過長(zhǎng)城.
3) have been in表示“在某地呆了多少時(shí)間”,常與時(shí)間段狀語(yǔ)連用.如：
I have been in Shanghai for three years．我到上海已有三年了.
He has been in London for half a month．他來(lái)倫敦已有半個(gè)月了.
再來(lái)說(shuō)went to,go to,be going to
went to就是go to的過去時(shí),常用于一般過去式的句子中,
go to是一般現(xiàn)在時(shí),
be going to是將來(lái)時(shí)態(tài)的.
而have been to ,have gone to這兩個(gè)是完成時(shí)的
如果還沒有分清楚過去時(shí),現(xiàn)在時(shí),將來(lái)時(shí),完成時(shí),那就自己去查吧!
可以嗎?
打字打得好可憐
