I have lunch every day. 還表示現(xiàn)在存在的一種狀態(tài). 如：我姐姐是一位老師．My sister is a teacher. 一般現(xiàn)在時態(tài)經(jīng)常與often（經(jīng)常）sometimes（有時）always（總是）usually（通常）等副詞連用，也經(jīng)常與every day（每天）, every week（每周）, every month（每月）, every term（每學(xué)期）, every year（每年）, once a week （一周一次），twice a year（一年兩次）等時間狀語連用。 一般現(xiàn)在時態(tài)分為be 動詞的一般現(xiàn)在時和實義動詞的一般現(xiàn)在時。 1） be動詞包括am，is，are. 中文為"是"， 這三個詞的用法要隨著主語的變化而變化。 "am" 用于第一人稱單數(shù)（I）; "is" 用于第三人稱單數(shù)（he，she，it）; "are "用于第一人稱復(fù)數(shù)（we），第二人稱單數(shù)和復(fù)數(shù)(you), 第三人稱復(fù)數(shù)（ they）。 可以記住以下順口溜： am管 "我"， is管"，她，它，他"， are管"大家"。 2） 一般疑問句和否定句 I am a teacher. (我是一位老師) You are his friend.（你是他的朋友） She is a nurse.（她是一名護士） 以上三個句子都是肯定句. 此.類句子變成疑問句和否定句時,有些地方的語序和漢語不同,需特別注意.變?yōu)橐蓡柧鋾r,把be 動詞"am，is，are" 放在句首,回答時也要使用be動詞；變?yōu)榉穸ň鋾r,把表示否定的not 放在 "am is are" 的后面, 其中可以簡寫為：is not---- isn't are not---- aren't， am not 沒有簡寫形式。 . 如：Am I a teacher? Yes, I am. (No, I am not.) Are you his friend? Yes, you are. (No, you are not.) Is she a nurse? Yes, she is. (No, she is not.) 注意：如果are not, is not放在句尾時，不能使用簡寫，必須寫出整個單詞。 否定句為：I am not a teacher. You are not his friend. She is not a nurse. 3）如果句子的動詞不是be 動詞 "am is are" 而是其他實義動詞, 疑問句和否定句要借助于助動詞"do"或者 "does"， 也就是說be 動詞和實義動詞原形不能同時使用。 這里的 "do"，"does" 本身沒有什么意義，只是幫助構(gòu)成疑問句和否定句. 一般疑問句讀時必須用降調(diào). "do"和 "does"的使用要隨著人稱的變化而變化。請看下面兩組句子，注意區(qū)分他們的共同點和不同點。 I go to school every day. He goes to school every day. I don't go to school every day. He doesn't go to school every day. Do you go to school every day? Does he go to school every day? Yes, I do. (No, I don't) Yes, he does. (No, he doesn't) 這兩組句子中，由于人稱的不同，句子的結(jié)構(gòu)也不同，具體如下： 當主語是第三人稱單數(shù)時，肯定句為：主語+動詞的s形式+賓語 否定句為：主語+助動詞doesn't+動詞原形+賓語 疑問句為：Does+主語+動詞原形+賓語 肯定回答和否定回答也要使用助動詞does. 注：第三人稱單數(shù)用了 does 后面就不用動詞的s形式了,而用動詞原形. 動詞的一般現(xiàn)在時態(tài), 除了第三人稱單數(shù)(he she it) 外,其余都用動詞原形。當主語是其他人稱時，肯定句為：主語+動詞原形+賓語 否定句為：主語+助動詞don't+動詞原形+賓語 疑問句為：Do+主語+動詞原形+賓語 肯定回答和否定回答也要使用助動詞do. 注：變?yōu)橐蓡柧?要在句首加"do" ; 變?yōu)榉穸ň? 要在動詞前面加"do not", 可以簡寫為 "don't". 2. 一般現(xiàn)在時，第三人稱單數(shù)作主語時，動詞的變化規(guī)則。 1） 一般在動詞后加-s詞尾。如，come-comes live-lives 2） 在以ch, sh ,s, x, 或o結(jié)尾的詞后要加-es, 如， teach-teaches catch-catches wish-wishes wash-washes miss-misses guess-guesses mix-mixes fix-fixes go-goes do-does 3） 以“輔音+y”結(jié)尾的詞，先變y為I 再加es,如， Try-tries study-studies reply-replies fly-flies 3look的用法 1) look like看起來象，其中l(wèi)ike 是介詞。如，He looks like his father. 2) look at看。。如，Look at the blackboard. 3) look the same看起來很像。如，Lucy and Lily look the same. 4) look for尋找.如，They are looking for the lost child. 5) look over（醫(yī)生）檢查The doctor is looking over the old woman. 6) Look up抬頭看；（在詞典或參考書中）查找 He’s looking up at the picture. 4. 詞語辨析 Wear意為“穿著，戴著”，表示穿，戴的狀態(tài)。而put on意思為“穿上，戴上”，表示穿，戴的動作。 5． stop doing sth停止做某事； stop to do停下來去做某事 6． remember to do sth 記著要去做某事；remember doing sth.記著（已經(jīng)）做過某事;remember sth/sb記得某物或某人 7． 復(fù)合形容詞構(gòu)詞法 1) 形容詞+動詞-ing,如，Our teacher is easy-going. 2) 名詞+過去分詞，如，This is a man-made satellite. 3) 數(shù)詞+名詞（單數(shù)），如，a ten-year-old boy 【注意】復(fù)合形容詞中的名詞要用單數(shù)。 4) 數(shù)詞+名詞（+ed）如，a three-legged table一張三條腿的桌子。 5) 形容詞+名詞 如，This is a full-time job. 6) 形容詞+名詞（+ed）如，He’s a warm-hearted person. 8．a(chǎn) little和 a bit都可以用來修飾不可數(shù)名詞，作定語。a bit在修飾名詞時必須在后面加上介詞of，如，a bit of water一點水，而用a little則說成a little water ◆unit8.
