二樓說的是對的，但為了加強(qiáng)語氣，建議把for 改成 becauseWe couldn't turn left just now, because a policeman was there.ps: police 后面用復(fù)數(shù)的原因是它是一個集體名詞，如people

Don't turn left, considering the policeman just now.

the police后要用 were, can't 應(yīng)改成couldn't .或者說 We couldn't turn left just now, for a policeman was there.

The police was there just now, so you can't turn left.
