Language points
1.We need to come up with a plan for…
我們必須想出一個(gè)計(jì)劃。
need 是一個(gè)常見(jiàn)的動(dòng)詞，表示“需要”之意。它既可以作實(shí)義動(dòng)詞，也可以作情態(tài)動(dòng)詞。其具體用法如下：
need用作實(shí)義動(dòng)詞，有“必要”、“必需”之意，有人稱、數(shù)和時(shí)態(tài)的變化，可以接名詞、代詞、動(dòng)名詞或帶to 的動(dòng)詞不定式作賓語(yǔ)，構(gòu)成疑問(wèn)句和否定句時(shí)要借助于助動(dòng)詞。如：
這個(gè)人在工作時(shí)需要一本英語(yǔ)詞典。
The man needs an English dictionary when he works.
你必需親自見(jiàn)他嗎？
Do you need to see him yourself?
need用作情態(tài)動(dòng)詞，意為“必須”、“必要”，沒(méi)有人稱、數(shù)等變化，后接不帶to 的動(dòng)詞不定式。
通常用于疑問(wèn)句和否定句中，構(gòu)成疑問(wèn)句和否定句時(shí)，不需要使用助動(dòng)詞。
你必須和你的同學(xué)去公園嗎？
Need you go to the park with your classmate?
他不必花掉這么多錢買這塊新手表。
He needn’t spend much money on this new watch.
【注意】 由need引出的疑問(wèn)句，答語(yǔ)表示肯定時(shí)用must或have to；表示否定時(shí)用needn’t或don’t have to。
A: Need I come to work tomorrow?
明天我需要來(lái)上班嗎?
B: Yes, you must / have to. 是的，你必須來(lái)。
A: Need I finish the work at once?
我需要馬上完成這項(xiàng)工作嗎？
B: No, you needn’t / don’t have to．
不，不必馬上完成。
2....and called up all his friends and told them
about the problem.
給他所有的朋友打電話告訴他們他的問(wèn)題。
call up 表示“給……打電話”，后面接指人的詞。
這個(gè)男孩給你打電話只是為了聊天嗎？
Did the boy call you up just for a chat?
“給……打電話”的常見(jiàn)說(shuō)法還有:

當(dāng)我到那時(shí)，他們正在給他們的老師打電話。
