動(dòng)詞第三人稱單數(shù)形式 主語有三單,動(dòng)詞也有三單,快點(diǎn)來習(xí)慣,體會在心里,一定要過關(guān).1、 概念動(dòng)詞第三人稱單數(shù)：主語是第三人稱單數(shù)，即謂語動(dòng)詞的發(fā)出者是it、she、he、可數(shù)名詞單數(shù)、不可數(shù)名詞等表示單數(shù)概念的詞時(shí)，實(shí)義動(dòng)詞后面要加-s或-es。（注意：若主語不是第三人稱單數(shù)形式，就直接用動(dòng)詞原形；若主語是三單，后有will等情態(tài)動(dòng)詞修飾時(shí)，動(dòng)詞也用原形。）2、 動(dòng)詞三單變化規(guī)則（只有一般現(xiàn)在時(shí)才有第三人稱單數(shù)）動(dòng)詞第三人稱單數(shù)的變化規(guī)則及發(fā)音規(guī)律，同名詞單數(shù)變復(fù)數(shù)大致相同，請認(rèn)真觀察。1、 大多數(shù)實(shí)義動(dòng)詞在詞尾加“s”，在清輔音后發(fā)音為/ s / ，在濁輔音及元音因素后發(fā)音為 / z /。 如：speakspeaks /s/ ; comecomes /z/ ; playplays /z/2、 以輔音字母加“y”結(jié)尾的動(dòng)詞，要先將“y”變?yōu)椤癷”，然后再加“es”，讀/z/。 如：studystudies /z/ ; flyflies /z/ 3、 以“s，x，ch，sh”結(jié)尾的動(dòng)詞，在詞尾加“es”，發(fā)音為/ iz / 。 如：teachteaches /iz/ ; watchwatches /iz/ 4、 以“o”結(jié)尾的動(dòng)詞,在詞尾加“es”。 常出現(xiàn)的兩個(gè)以“o”結(jié)尾的動(dòng)詞go和do后加“es”，讀/z/ 。 如：gogoes /z/ ; dodoes /z/ 5、 記住最為特別的be的三單is ；have的三單是has。注意（1）下面兩個(gè)動(dòng)詞變?nèi)龁螘r(shí)，原詞的元音部分的發(fā)音發(fā)生了較大的變化，要記憶。 如：do/du:/ does/d z/ ; say/sei/ says /sez/ （2）以不發(fā)音字母“e”結(jié)尾的開音節(jié)詞，如果尾音是s，z時(shí)，加“s”后字母“e”發(fā)音， 與所加“s” 一起讀做iz。 如： closecloses iz 3、 動(dòng)詞第三人稱單數(shù)的句子結(jié)構(gòu)。1、 肯定/否定句 三單+is +表語 . 三單+動(dòng)詞第三人稱單數(shù)+其他 . 三單+is+not+表語 . 三單+doesnt +動(dòng)詞原形+其他 .2、 一般疑問句 1）當(dāng)謂語動(dòng)詞是be動(dòng)詞時(shí)，一般疑問句結(jié)構(gòu)為“Is+三單+表語？”。它的肯定回答為： Yes, 三單+is. ;否定回答為：No，三單+isnt.。 2）當(dāng)謂語動(dòng)詞是實(shí)義動(dòng)詞時(shí)，在肯定句句首加助動(dòng)詞does,即“Does+三單+動(dòng)詞原形+ 其他？”。它的肯定回答為：Yes，三單+does.;否定回答為：No，三單+doesnt.。3、 特殊疑問句 特殊疑問詞+一般疑問句4、 要點(diǎn) 1）一定要看準(zhǔn)句子的主語是第三人稱而且還是單數(shù)； 2）經(jīng)常與頻率副詞連用：always (一直，總是），usually（通常），often (經(jīng)常），sometimes （有時(shí)），seldom (很少），hardly (幾乎不），never (從不），once a day (一天一次），twice a week(一周兩次），three times a month(一個(gè)月三次）。 如:I often speak Chinese. 我經(jīng)常說漢語。練習(xí)題I、寫出下列動(dòng)詞的第三人稱單數(shù)。go do buy draw shout play teach make catch find swim jump begin dig help miss sing finish give keep dance worry sit hear match get have love learn cry fly study come call smile be write stop open check look drink leave read pick eat walk start tell push die _ live _ show vote judge buy _ carry_ borrow listen wash II、用動(dòng)詞的正確形式填空。1、I _ (go) home by bus. 2、Jack _(go) home by bike.3、When _(do)he get up? 4、Her mum _(run) to the goose.5、He_(do not)like apples. 6、Sam_(put) it under his arm.7、The boy_(chase) it. 8、Kitty_(watch)TV everyday.9、John cant_(find) his watch. 10、Where _(do)Grandma live?11、Miss Wang_(live) in America now. 12、The girls_(give) the key to Sally.13、That key _(open) the old box. 14、She _(say) “I like these puppets”.15、What_(do)Alice find? 16、Which toy_(do) she like?17、He doesnt_(know)her name. 18.、Mike _( cook ) in a restaurant . 19、He_( speak ) Japanese . 20、How does he_(go)to the post office?21、He often _( have ) dinner at home . 22、Liu Tao _ ( do ) not like PE(體育）.23、She _(do) homework by herself. 24、They _ (do) homework by themselves.25、Kate _ (walk) to school every day. 26、Lucy and Lily _ (walk) to school every day.27、David and Ben _(be ) in Class Four ,Grade Seven .28、The girl _（teach） us English on Sundays.29、He_(feed)them at 8:00 in the morning.30、She _( ride ) to school from Monday to Friday .31、We _ (not watch ) TV on Sunday .32、Su Hai and Su Yang _(work ) in a shop(在商店）.33、There_( be) some water in the bottle(瓶子）.34、The giant（巨人）_(climb) up the beanstalk（豆莖）.35、Michael usually_ (listen) to the radio in the morning.III、選擇正確的單詞填到括號里。1、 What does Candy _(wants, want ) to be ?2、 He shouldnt _ (throw, throws ) rubbish on the floor(草地）.3、 Peter _ (help, helps ) his mother with the housework(家務(wù)）.4、 She never _(run, runs ) in the library(圖書館）.5、 We will _(fly, flies ) kites on this Sunday .6、 Tom and Mary _(has, have ) pen pals in China .7、 They _(speaks, speak ) English after class.8、 He _(dont , doesnt ) get up early .9、 What _( do, does ) your father do ?10、 Let us _(fly , flies ) kites on this Friday afternoon .IV、將下列句子改為第三人稱He的句型（看例句）。例句：I brush my teeth once a day .He brushes his teeth once a day .1、 I come from China. _2、 You have a big black knife. _3、 What do you do ? _4、 Our parents work in an office . _5、 What color are your clothes ?_V、A：用括號里所給詞的適當(dāng)形式。1、The desk _ _ (have)four legs.2、She _ _ (do) her homework every day.3、Danny_ _ (fall) and breaks his tail.4、He _ _ (live) in Shijiazhuang.5、He _ _ (need) a pair of shoes.6、Danny_ _ (see) the apple tree.7、She_ _ (come) from America.8、My mother and father_ _ (walk) to the office every day.9、Danny and her mother sometimes _ _ (go) for a walk after supper.10、The train_ _ (leave) at 10:13 am.11、That hat _ _ (look) like a cat.12、Danny _ _ (hurt) his nose.
