The plane was late and detectives were waiting at the airport all
morning.They were expecting a valuable parcel of diamonds from South
Africa.A few hours earlier,someone had told the police that thieves
would try to steal the diamonds.When the plane arrived,some of the
detectives were waiting on the airfield.Two men took the parcel off
the plane and caried it into the Custom House.While two detectives
were keeping guard at the door,two others opened the parcel.To their
surprise,the precious parcel was full of stones and sand!
☆someone had told...
過(guò)去完成式，過(guò)去以前發(fā)生的事情
...that thieves would try to...
would+do:過(guò)去將來(lái)式，間接方式，轉述，站在過(guò)去看未來(lái)
☆when和while都表示當……的時(shí)候，考試時(shí)一定選when
while能用when代替，但是when卻不一定能用while代替
while+從句，動(dòng)作一定會(huì )延續
when+延續性動(dòng)作/瞬間動(dòng)詞
when he arrived/died
用過(guò)去進(jìn)行時(shí)：
在過(guò)去的某一點(diǎn)時(shí)間，或者是過(guò)去某一動(dòng)作同時(shí)發(fā)生的另外一個(gè)動(dòng)作。瞬間動(dòng)詞（如arrive）無(wú)進(jìn)行時(shí)態(tài)。
同時(shí)發(fā)生的兩個(gè)動(dòng)作
1.一個(gè)用一般過(guò)去時(shí)，另一個(gè)用過(guò)去進(jìn)行時(shí)。
2.分工的情況，均用過(guò)去進(jìn)行時(shí)

★Special difficulties
vt+adv+賓語(yǔ)(n)
vt+賓語(yǔ)(n/pron)+adv
vi+prep+賓語(yǔ)(n)
賓語(yǔ)的位置和詞性取決于施加動(dòng)作的動(dòng)詞
介詞出現，一定要有賓語(yǔ)，所以v+prep+賓語(yǔ)(n)
副詞可以省略，v+賓語(yǔ)(n/pron)+adv或v+adv+賓語(yǔ)(n)
是副詞還是介詞要看動(dòng)詞是及物動(dòng)詞還是不及物動(dòng)詞
vt-adv vi-prep
而判斷是不是及物動(dòng)詞就要看平時(shí)的積累了
特殊：1.make up...->make(vt)up one's mind
語(yǔ)法上可以改為make one's mind up,但習慣上不改
2.ask for...
表面上ask（vt），可改。但要注意是ask (sb) for sth
的省略，所以不能改
