動詞-ing作主語的幾種形式：動詞-ing形式作主語時,根據(jù)主謂一致的原則,謂語動詞使用________形式。但是意義不同的兩個動詞-ing形式并列作主語時,謂語動詞要用_________形式。

Readingaloudisagoodwayinlearningalanguage.⑶ListeningtotheEnglishtapesandwatchingEnglishfilmsaregoodwaystolearnEnglish.1.-ing形式直接放在句首，表示抽象的、經(jīng)常的以及習(xí)慣性的動作或狀態(tài)。Itisnogood/usedoing...做...是沒用的。Itisnofundoing…做...沒有樂趣。Itisawasteoftimedoing…做…是浪費(fèi)時間Itisworth/worthwhiledoing…做...是值得的。此類句式常見的有:2.有時為了句子平衡，避免頭重腳輕,

用it在句首作形式主語，而把真正的主語(動詞-ing短語)后置。注意：此類句型只限于以上某些形容詞或少數(shù)名詞,如:worth,worthwhile,awasteoftime,

nouse/good/fun等。Itisworthreadingsuchawonderfulnovel.這么好的書很值得一讀。It’snousecomplainingwithouttakingaction.不行動只抱怨是沒有用的。注意：動名詞作主語用it充當(dāng)形式主語的情況很少，上表中是最常見的句式結(jié)構(gòu)。不定式作主語時，常用it充當(dāng)形式主語，如：It’snoteasytolearnaforeignlanguagewell.學(xué)好一門外語不容易。It’sdifficultforustofinish

theworkinaweek.對我們來說，一周之內(nèi)完成這項(xiàng)工作很困難。1.Beingaddictedtosmartphones
