clear: 指清除不要的东西。
sweep: 指用扫帚等进行清扫，也用作比喻。

clean, cleanse

这两个单词的拼写非常相近，且都包含动词"净"的意思。
clean: 意思是“使洁净”、“把...去垢”（to make clean by washing，dusting，sweeping or brushing）。如：to clean a dress，room，hand，shoe，watch等。

• please clean your shoes.
  请把鞋刷干净。
• he cleaned the floor with water.
  他用水冲洗地板。
• i have got my watch cleaned in a watch-shop.
  我的表已在一家钟表店清洁过了。

cleanse: 意思是“清洗干净”，“使...纯洁”（to make thoroughly clean or make pure）。为此，cleanse含有“彻底洗清”之意味，语义比clean强得多。clean和cleanse的另一区别是前者为一般用语；后者是正式的（formal）或古旧的用语，有时它还能用于比喻意义，例如to cleanse one's soul洗涤心灵；to cleanse the heart of sin 洗心革面；ethnic cleansing 种族清洗/灭绝。

• we have cleansed the garden of weeds.
  我们已把花园里的杂草清除干净。
• she bought some detergent and antiseptic from a dyeing and cleansing store.
