動(dòng)詞可以放在句首，具有助動(dòng)詞

親愛的同學(xué)們，今天小編準(zhǔn)備跟大家分享一些情態(tài)動(dòng)詞的用法。情態(tài)動(dòng)詞在英語學(xué)習(xí)中是比較重要的一個(gè)版塊，包含許多細(xì)碎的知識(shí)點(diǎn)，需要我們著重記憶。情態(tài)動(dòng)詞不止包含一個(gè)動(dòng)詞，今天小編先為大家講解一下should的用法。 首先，should后直接跟動(dòng)詞原形，沒有人稱和數(shù)的變化, 如： You should go home at once. He should eat more vegetables. I should finish my homework before nine. should的否定形式是在should后面加not, 可以縮寫為shouldn’t, 意為“不應(yīng)當(dāng); 不應(yīng)該”。如: You

可以明顯地看出，他是一名教師。 【難點(diǎn)】as意為―如，照(某種事實(shí)或情況)‖，在本句中為關(guān)系代詞，指代第二個(gè)分句，as代替整個(gè)句子作主語時(shí)，謂語動(dòng)詞通常必須用單數(shù)。 ? 10. Great as Newton was, many of his ideas ____ today and are being modified by the work of scientists of our time.? A. are to challenge ? ? ? ? ?B. may be challenged ? ? ?C. have been challenged ? ? ?D. are challenging? ? ?10. C)? 【句意】盡管牛頓非常偉大，然而他的許多觀點(diǎn)當(dāng)前正受到懷疑，并且當(dāng)今的許多科學(xué)家正在努力對(duì)這些觀點(diǎn)進(jìn)行修正。?? 【難點(diǎn)】challenge意為―挑戰(zhàn)，懷疑‖，常用作及物動(dòng)詞。本句中牛頓的觀點(diǎn)受到挑戰(zhàn)為一個(gè)當(dāng)前已經(jīng)發(fā)生的事實(shí)，故采用現(xiàn)在完成時(shí)的被動(dòng)語

別的： 1、表示請(qǐng)求、建議等，would比will委婉客氣。如： Would you pass me the book? 2、表示意志、愿望和決心。如： I will never do that again. 我再也不會(huì)做那了。 They asked if we would do that again. 他們問到，我們是否愿意再次做那。 3、 用“will be”和“will(would) + have + 過去分詞”的結(jié)構(gòu)表示推測(cè)，主要用于第二、三人稱。前者表示對(duì)目前情況的推測(cè)，后者表示對(duì)已經(jīng)完成的動(dòng)作或事態(tài)的推測(cè)。如： This will be the book you want. 這本書應(yīng)該是你想要的。 He will have arrived by now. 他現(xiàn)在應(yīng)該已經(jīng)到了。 The guests would have arrived by that time. 那時(shí)，客人們應(yīng)該都動(dòng)詞到了。 I thought you would have finished this by now. 我認(rèn)為你現(xiàn)在應(yīng)該已經(jīng)完成了。 4、will表示習(xí)慣、請(qǐng)求，固有性質(zhì)等。 Everyday he will sit here hour after hour doing nothing.（習(xí)慣） 他每天

D lying是lie的現(xiàn)在分詞，在句中作后置定語。? 2 C ―It is worth doing‖是固定結(jié)構(gòu)，意思是―干… …是值得的‖。 3 B 4 D 5 C? 6 ?A 分詞短語作定語時(shí)，應(yīng)放在被修飾的名詞后，相當(dāng)于一個(gè)定語從句：Most of the artists who were invited to the party were from South Africa. 7 D? 8 A 分詞短語作狀語時(shí)，其邏輯主語必須與句子的主語一致。該分詞的邏輯主語是the trees，與動(dòng)詞give含有動(dòng)賓關(guān)系，因而用過去分詞given表示被動(dòng)，Give more attention這個(gè)條件狀語相當(dāng)于狀語從句If they had been given more attention。? 9 ?A making是現(xiàn)在分詞用作狀語，表示伴隨情況或做補(bǔ)充說明。B和C屬語法錯(cuò)誤。D項(xiàng)是不定式，可作目的狀語，但目的狀語前通常不能用逗號(hào)。 10 D

行時(shí)和被動(dòng)語態(tài)。 進(jìn)行時(shí)態(tài)中的be 此時(shí)，be可以與主要?jiǎng)釉~的現(xiàn)在分詞一起，構(gòu)成各種進(jìn)行時(shí)態(tài)。如： 1. He is reading in the library now.(現(xiàn)在進(jìn)行時(shí)) 2. She was swimming in the river this time yesterday.(過去進(jìn)行時(shí)) 助動(dòng)詞 特殊句型中的be 特殊句 There be句型 與上面用法都動(dòng)詞中有一個(gè)叫做be動(dòng)詞。英語名“be verb”。除了原形不同的是，be可以與there一起構(gòu)成there be句型，用來表示存在。 幾個(gè)常見的例句： 1.
