2016年職稱英語衛(wèi)生類備考語法知識：人稱代詞

人稱代詞：人稱代詞代替人和事物的名稱,分為主格和賓格兩種形式。

1、主格用來作句子的主語、表語。如：I often go shopping on Sundays.(星期天我常去購物) / Are they from Brazil?(他們是巴西人嗎?) / Where have they gone?(他們上哪兒去了?) / That's it.(就那么回事) / It's he!(是他!)

2、賓格用來作及物動詞或者介詞的賓語。如：Who teaches you English this year?(今年誰教你們的英語?) / Help me!(救救我!) / We often write letters to her.(我們常給他寫信)

3、人稱代詞作表語或者放在比較狀語從句連詞than或as之后時,可以用主格形式,也可以用賓格形式,口語中大多用賓格。如：--Who is it?(是誰?) –It's I/me.(是我。)

4、三個不同人稱同時出現(xiàn),或者主語中包含“我”時,按照“you→he→I”的順序表達。如：

Both he and I are working at that computer company.(我和他都在那家電腦公司上班) –Who will go there?(誰要去那兒?) –You and me.(你和我)

5、人稱代詞it除了可以指人指物之外,還可以表示“時間、天氣、溫度、距離、情況”等含義,此外還可以作“非人稱代詞”使用,替代作主語或者賓語的不定式、動名詞或者名詞性從句。如：--What's the weather like today?(今天天氣怎樣?)—It's fine.(天氣晴好) / --What's the time?(幾點啦?) –It's 12：00.(12點) / It's a long way to go.(那可要走好長的路) / It took him three days to clean his house.(打掃屋子花了他三天的時間) / It is very clear that the public want to know when these men can go into space.(很顯然,公眾想知道這些人什么時候能進入太空) / We found it very difficult to learn a foreign language well.(我們發(fā)覺要學好一門外語是非常困難的)
