10．---Many peoplewon't realize that it is important to get along well with others until friends go away from them．（直到朋友離開他們才意識到與他人好好相處很重要） （until）
---Yes．So we must learn to communicate with others．

Answer 1

分析 許多人直到朋友離開他們才意識到與他人好好相處很重要．
---是的，所以我們必須學(xué)會和他人溝通．

解答 答案：won't realize that it is important to get along well with others until friends go away from them．
結(jié)合句意表達(dá)的是直到…才，結(jié)合所給的until用not…until…，遵循主將從現(xiàn)的規(guī)則，主句用一般將來時(shí)will+動詞原形，realize意識，后加賓語從句，that作為引導(dǎo)詞，做某事是怎樣的用it's+adj+to do sth，從句表達(dá)的是客觀事實(shí)用一般現(xiàn)在時(shí)，important重要的，get along well with others 與他人好好相處，until從句用一般現(xiàn)在時(shí)，主語friends復(fù)數(shù)，離開go away fron them，故答案是won't realize that it is important to get along well with others until friends go away from them．

點(diǎn)評 not…until直到…才 
表達(dá)的意思是"直至某時(shí)才做某事"．動詞為延續(xù)性或非延續(xù)性都可以．
否定句：
She didn"t arrive until 6 o"clock．
她直到6點(diǎn)才到．
Don"t get off the bus until it has stopped．
公共汽車停穩(wěn)后再下車．
