join

　　[誤] Did you attend the football club

　　[正] Did you join the football club

　　[析] join經(jīng)常用于參加某個(gè)團(tuán)體、政黨，并作為其中的一個(gè)成員;attend則重點(diǎn)強(qiáng)調(diào)出會(huì)議、到場(chǎng)，而不一定進(jìn)行具體活動(dòng)，如： Did you attend the meeting yesterday而take part in則強(qiáng)調(diào)參與某些具體活動(dòng)或運(yùn)動(dòng)，如： I take part in the football game.

　　just

　　[誤] I have finished my work just now.

　　[正] I finished my work just now.

　　[析] just now意義剛才，所以句中的謂語(yǔ)動(dòng)詞要用過(guò)去式。

　　[誤] Just I won the game.

　　[正] I just won the game.

　　[析] just單獨(dú)使用時(shí)不應(yīng)放在句首，而應(yīng)放于① be動(dòng)詞之后，如： He is just a student.② 名詞與一般動(dòng)詞之間。③ 用在第一助動(dòng)詞之后，如： I have just returned home. 但just與其他詞組成詞組時(shí)，如just now, just then, 則可用于句首和句尾。如： Just then he saw the bus coming.

　　just justly

　　just常用于三種含意： ① 恰好，如： Its just five oclock. ② 僅僅，相當(dāng)于only, 如： I have just enough money to buy a dictionary. ③ 不久前，如： I just missed my old friend; He left a few minutes ago. 而justly其意為公正的，如： He was justly punished for his crimes.
