  八年級(jí)上冊(cè)英語(yǔ)第二單元知識(shí)點(diǎn)2

  重點(diǎn)句子:

  1.How often do you exercise? 你(你們)多久鍛煉一次身體?

  解析:How often + 助動(dòng)詞do(does或did) + 主語(yǔ) + do sth.?

  疑問(wèn)詞how often是問(wèn)頻率(多久一次),(在這里助動(dòng)詞do(does或did) 是起幫助構(gòu)成疑問(wèn)的作用)與一般現(xiàn)在時(shí)或一般過(guò)去時(shí)連用,回答一般是用表示頻率的副詞,如:once, twice, three times…, sometimes, often, quite, often, never, every day, once a week , twice a month , three times a month , three or four times a month等。

  Eg1)——How often do you go to the factory?

  ——Twice a week.你們多久到工廠(chǎng)去一次?每星期兩次。

  Eg2)——How often does he go shopping?

  ——He goes shopping once a month.

  2.——“What do you usually do on weekends?”

  ——“ I usually play soccer.”“周末你通常做什么?”“我通常踢足球。”

  解析:第一個(gè)do為助動(dòng)詞, 在這起幫助構(gòu)成疑問(wèn)的作用;而第二個(gè)do則是實(shí)義動(dòng)詞。

  Eg1)What do you usually do on weekends? I often go to the movies.

  Eg2)What does she usually do on weekends? She sometimes go hiking.

  3.——“What’s your favorite program?”

  ——“It’s Animal World.”“你最喜歡什么節(jié)目?”“動(dòng)物世界。”

  4.As for homework , most students do homework every day .

  解析:as for...意思是“至于;關(guān)于”,常用于句首作狀語(yǔ),其后跟名詞、代詞或動(dòng)詞的-ing形式(即動(dòng)名詞)。

  如:As for him,I never want to see him here. 至于他,我永遠(yuǎn)不希望在這里見(jiàn)到。

  As for the story,you'd better not believe it. 關(guān)于那故事,你最好不要相信。

  As for myself, I don’t want to go now. 至于我自己,我現(xiàn)在不想去。

  As for the man, I know nothing about him. 至于那個(gè)人,我什么都不知道。

  5. Mom wants me to get up at 6:00 and play ping-pong with her .

  解析:want to do sth. 意思是“想要做某事”;

  want sb. to do sth.意思是“想要某人做某事”。如:

  Eg1)Do you want to go to the movies with me?你想和我一起去看電影嗎?

  Eg2)The teacher doesn't want us to eat hamburgers.老師不想讓我們吃漢堡包。

  注意:有很多動(dòng)詞后面用這種結(jié)構(gòu)做動(dòng)詞的復(fù)合賓語(yǔ),如:

  ask sb. to do sth. 叫某人做某事

  tell sb. to do sth. 告訴某人去做某事

  help sb. (to) do sth. 幫助某人做某事

  6. She says it’s good for my health.

  解析:be good for...表示“對(duì)……有益(有好處)”;

  其反義為:be bad for...。(這里for 是介詞,后跟名詞、代詞或動(dòng)名詞)如:

  Eg1)It's good for us to do more reading. 多讀書(shū)對(duì)我們有好處。

  Eg2)Reading in bed is bad for your eyes.在床上讀書(shū)對(duì)你的眼睛有害。

  7. How many hours do you sleep every night?

  8. I exercise every day , usually when I come home from school .

  9. My eating habits are pretty good .

  解析:這里pretty相當(dāng)于very 。

  10.I try to eat a lot of vegetables , usually ten to eleven times a week .

  解析:try to do sth.表示“ 盡力做某事 ” ,不包含是否成功的意思

  try doing sth.表示“(用某一辦法)試著去做某事”。如:

  eg)You’d better try doing the experiment in another way.你最好試試用另一種方法做這個(gè)試驗(yàn)。

  11. My healthy lifestyle helps me get good grades.

  解析:help sb.(to) do sth.幫助某人做某事

  12. Good food and exercise help me to study better.

  解析:這里better是well的比較級(jí),而不是good的比較級(jí)

  13.Is her lifestyle the same as yours or different?

  =Is her lifestyle the same as your lifestyle or is her lifestyle different from yours?

  解析:be the same as … / be different from …

  14. What sports do you play ?

  15. A lot of vegetables help you to keep in good health .

  解析:keep in good health = keep healthy = stay healthy

  16. You must try to eat less meat .

  解析:try to do sth.表示“盡力做某事” ,不包含是否成功的意思,less是little的比較級(jí)

  17. That sounds interesting.

  解析:這是“主語(yǔ)+系動(dòng)詞+表語(yǔ)”結(jié)構(gòu)的簡(jiǎn)單句。

  sound(聽(tīng)起來(lái)),look(看起來(lái)),smell(聞起來(lái)),taste(嘗起來(lái)),feel(覺(jué)得),seem(好象),grow(變得),get(變得)等詞在英語(yǔ)中可用作系動(dòng)詞,后跟形容詞作表語(yǔ)。如:

  Eg2)The music sounds very sweet. 這音樂(lè)聽(tīng)起來(lái)很入耳。

  Eg3)The smoke grew heavier and heavier. 煙霧變得越來(lái)越濃了。

  解析:kind of = a little

  a kind of 一種

  19.Exercise such as playing basketball is fun.像打籃球這樣的鍛煉是有趣的。

  20.although=though雖然 <不能與but連用>

  如:Although he is old, he is quite strong.(He is old, but he is quite strong.)

  解析:句子中,有although或though就不可再用but,但可用yet或still“仍然,還”;

  與之類(lèi)似的情況:有because就不能再用so.

  21.She says it’s good for my health.她說(shuō)它對(duì)我的健康有好處。

  解析:be good for對(duì)…有益;其反義詞組:be bad for對(duì)…有害

  如:Eating vegetables is good for your health.吃蔬菜對(duì)你的健康有益。

  辨析:be good for ,be good at ,be good with

  be good for“對(duì)…有益”;

  be good at“擅長(zhǎng)于”;

  be good with“和…相處的好”;

  如:I’m good at playing football.

  Are you good at children?

  22.How come?怎么回事?

  解析:表示某件事很奇怪,有點(diǎn)想不通??蓡为?dú)使用,也可引導(dǎo)一個(gè)問(wèn)句,相當(dāng)于疑問(wèn)詞why.但how come開(kāi)頭的特殊疑問(wèn)句使用的仍是陳述語(yǔ)序。

  如:How come you didn’t tell me about it?

  =Why didn’t you tell me about it?你怎么不早點(diǎn)告訴我這件事?

  23.well,how about Tuesday?哦,那星期二怎么樣啊 ?

  解析:How about…?=What about …?,“…怎么樣”,用來(lái)向?qū)Ψ秸髑笠庖?jiàn)。

  如:It’s very sunny today ,how/what about playing tennis?

  24.Twenty percent don’t exercise at all.20%的學(xué)生根本不鍛煉。

  解析:“not…at all”“一點(diǎn)也不;根本不”

  如:He didn’t do his homework at all yesterday.昨天他根本沒(méi)有做作業(yè)。

  拓展:not at all “不客氣”=you are welcome.

  如:---Thank you very much.

  ---Not at all
