固定用法與辨析
1. 辨析gather與collect:
兩詞都表示"集中，歸攏"，但兩者有細(xì)微區(qū)別。
gather既可用于人，也可用于物。如：
gather flowers 采集花 gather one's ideas together集中思想。
collect很多場(chǎng)合與gather完全同義，但一般只用于物，指有選擇或有一定計(jì)劃將零散事物歸攏。如：
collect money: 籌募資金 gather money 攢錢。
2. 辨析seek 與search:
兩詞都表"搜尋"，但有差別。
seek指對(duì)高目標(biāo)或抽象事物的追求。如：seek knowledge渴望知識(shí)。
而search指仔細(xì)尋找或檢查某地點(diǎn)或某人。如：
The police searched his house. 警察搜查了他的房子。
3. 辨析rubbish與refuse:
兩詞都表"廢物，垃圾"，但兩者有細(xì)微差別。
refuse指堆積在一起的破爛無用東西。如：
The refuse was unloaded at the city dump. 垃圾傾倒在城市的垃圾場(chǎng)上。
rubbish指垃圾特意集中起來以便清除掉，但不象refuse那樣成堆成批的存在，該詞也常用于比喻。如：
Put the rubbish into the fire. 把垃圾燒掉。 He talked a lot of rubbish. 他說了一大堆廢話。
4. 辨析sort of與a sort of:
sort of是口語用語，只能作狀語，放在所修飾的動(dòng)詞、形容詞前，表示"有幾分，有點(diǎn)兒"。
I sort of thought you might do it. 我有幾分料到你會(huì)這么做。
a sort of 只作定語，表示"一種……"。如： a new sort of radio 一種新型收音機(jī)。
