　　英語學習中我們常常會遇到各種各樣的語法，其中時態(tài)考察是比較常遇見的一種類型的題目。本文，伊頓教育一對一輔導小編就分享現(xiàn)在進行時講解及練習，幫助同學們更好的掌握英語中，現(xiàn)在進行時態(tài)的使用!!!下面，就跟著小編一起學起來吧!!!

　　01 概念

　　表示正在發(fā)生的事情或動作，常和now，look，listen連用。

　　eg：We are listening to music now.　我們現(xiàn)在正在聽音樂。

　　Listen! He is playing the piano. 聽!他正在彈鋼琴。

　　02 結構

　　1.be + 動詞現(xiàn)在分詞(即：動詞-ing形式)，be + doing 是一個整體，不能分開。

　　2.be 隨著主語的變化而變化，doing的變化規(guī)則根據(jù)現(xiàn)在分詞的變化規(guī)律來定。

　　03 動詞現(xiàn)在分詞的構成規(guī)律

　　1.一般情況下,在動詞原形后直接加-ing;

　　eg：work→working do→doing　　play→playing

　　2.以不發(fā)音字母e結尾的動詞，先去掉e，再加-ing;

　　eg：dance→dancing　　come→coming

　　3.在重讀閉音節(jié)(即：輔音+元音+輔音)的動詞中，要先雙寫末尾的輔音字母，再加-ing;

　　eg：get→getting　 shop→shopping

　　run→running　 swim→swimming

　　4.以 ie 結尾的重讀閉音節(jié)詞，將ie改成y再加ing。

　　eg：lie→lying die→dying

　　04 現(xiàn)在進行時的各種句式變化

　　1.否定句

　　方法：直接在be的后面加not。

　　eg： They are running.　→They are not running.

　　2.一般疑問句

　　方法：直接把be放在主語的前面，其余位置不變。

　　eg：：They are running.　→Are they runnin?

　　3.特殊疑問句

　　方法：如果就劃線部分提問事情或動作時，用What…doing?

　　eg：They are swimming in the sea now.

　　→What are they doing in the sea now?
