Hiya,
1. ジョーンズさんはが五千円しか払わなかったので、丸山先生は びっくりしてしまった。
It looks as if this should mean "Prof. Maruyama was suprised because Mr Jones paid (him) only 5,000 yen".
However, I do not understand はが.
2. 日本の女性たちがみんなおとなしくて、何も文句を言わ ないから、男性たちが勝手なことをしてるんじゃないん ですか。
I get the main part as: "Japanese women are all submissive and never complain, so the men do exactly as they please..."
Then I can never quite remember how to deal with じゃないんですか. Is it OK to translate this as "Isn't the case that..." or "Isn't it a fact that..." or similar?
3. Two women are discussing desirable qualities in a husband.
高橋: やっぱり家庭を大切にする人じゃないと困りますよね。
田中: 高橋さんもそういう人を早く見つけなさいよ。
My translation:
Ms Takahashi: "Of course, it's bad if the man (you marry) doesn't value home and family."
Ms Tanaka: "You should quickly find a man like that (i.e. a man who does value home and family) too ("too" possibly referring to a third woman previously mentioned)!"
Does this look right?
4. The speaker is talking about the role of women in the Japanese workplace.
それに、お茶くみもだんだんやめようっていう声があっ て、私の会社でも近いうちにお茶の機械を入れることに なるらしいです。
My translation: "Also, there are people (lit. voices) saying that the practice of serving tea (by Japanese women) should gradually stop, and even in the company where I work, it seems that they'll soon be installing a (tea-making) machine."
Is this OK?
I parsed やめようっていう as やめよう (probable/volitional form of やめる) + って + いう. Is that correct? Is it reasonable to translate this as "(people say the practice) should stop"?
