二、修筑一条水泥路,甲队独修需12天完成,乙队独修需15天完成,乙队先做全程的1/10,剩下的由甲、乙合做,还需多少天就能完工?

A、were
B、was , with
A、did
B、planted , digged
A、else
B、fed , was
A、want

B:went / with
A:did
B:planted / dug
A:else
B:fed / was
A:wanted
二:

1、根据上下文,完成下列对话。
A:Where(were)you last week?
B:I(was)on a farm (near )my family.
A:What(did)you do on the farm?
B:We(planted)trees and(pulled)up carrots.
A:What(else/others)did you do?
B:We(feed)cows.It(was)fun!
A:Wonderful!I(would like)to go to the farm,too.
二、修筑一条水泥路,甲队独修需12天完成,乙队独修需15天完成,乙队先做全程的1/10,剩下的由甲、乙合做,还需多少天就能完工?
解:设甲队一天完成的工作量是X,乙的是Y,
则:所有的工程量为:12X 或者15Y
又因为 12X=15Y,则 X=15Y/12
乙队先做全程的1/10,则还剩下工程量为:15Y*9/10
剩下的甲乙合做需要的天数为:
(15Y*(9/10))/(15Y/12+Y)=6
注:第一题的英语从对话上理解因为开头一句有last week 所以一般来说就是针对的过去式,然后根据逻辑可以判定其他空格填什么 也许会有偏差 请谅解!

A were B was with A did B planted picked A else B rode is A want

A:Where(were )you last week?
B:I( was)on a farm (with )my family.
A:What( did)you do on the farm?
B:We(planted )trees and(dig )up carrots.
A:What( else )did you do?
B:We( feeded )cows.It(was )fun!
A:Wonderful!I( want )to go to the farm,too.
二、修筑一条水泥路,甲队独修需12天完成,乙队独修需15天完成,乙队先做全程的1/10,剩下的由甲、乙合做,还需多少天就能完工?
甲队的工效:1/12,乙队的工效:1/15
(1-1/10)÷(1/12+1/15)=6
答 :6天
