巧记瞬间性动词的转换“开始离去借来还，出生入死买到家，穿衣入睡要感冒，开开关关变结束。”1beginbeon6returnbeback2leavebeawayfrom7joinbein3gobeoff8diebedead4borrowkeep9buyhave5comebehere10arrivebehere10reachbehere11putonwear13catchacoldhaveacold14openbeopen15closebeclosed17end/finishbeover16becomebe12fallasleepbeasleep注意点四：havebeenin,havebeento与havegoneto的用法1、have(has)beenin表示“在某地（多长时间）”，现在仍在那里。常与表示一段时间的状语连用。例如：Mr.BrownhasbeeninShanghaiforthreedays.布朗来上海已经有三天了。TheyhavebeeninCanadaforfiveyears.他们到加拿大有五年了。2、have(has)beento表示“曾经去过某地”，现在已经不在那里了。可与just,ever,never等连用，例如：Ihavejustbeentothepostoffice.我刚才去邮局了。MaryhasneverbeentotheGreatWall.玛丽从未去过长城。HaveyoueverbeentoHangzhoubefore?你以前曾经去过杭州吗？Have(has)beento后面可接次数，表示去过某地几次。例如：Theyhavebeentothatvillageseveraltimes.他们去过那个村庄好几次了。3、have(has)goneto意为“到某地去了”，表示到了某地或正在去某地的途中。总之，说话时该人不在现场，例如：----WhereisTom?----Hehasgonetothebookshop.他到书店去了。JackJohnsonhasgonetoLondon.

杰克.约翰逊到伦敦去了。have/hasbeento和have/hasgoneto的用法区别1“Have/hasbeento+地名”表示曾经去过某地，说话时已经回到说话地点，常与once、twice、ever、never等时间连用。2“have/hasgoneto+地名”表示去某地了，现在没有回答，人不在说话地点。巧记：beento，goneto意不同，两者用法要记清；

havebeento+地名，曾经到过某地行；

havegoneto+地点，到某地去了一走远。用法四用have/hasbeento和have/hasgoneto填空—Hi，Lucy，

haddid

have现在完成时表示过去发生或已经完成的某一动作对现在产生的影响或结果，强调的是现在的情况。所以它不能和表示过去时间状语连用；而一般过去时只单纯表示过去的动作或状态，和现在不发生关系，可以和表示过去的时间状语连用。一）现在完成时与一般现在时的句型转换eg：IhavestudiedEnglishforthreeyears-----IstudiedEnglishthreeyearsago-----ItisthreeyearssinceIstudiedEnglish试一试，用所给词的正确形式填空1I

③若词尾为“辅音字母加y”，则改y为i加ed。词尾为“元音字母+y”时，直接加d；如:
