【應掌握的句子】
1. How often do you exercise? 你(你們)多久鍛煉一次身體?
How often + 助動詞do(does或did) + 主語 + do sth.? 疑問詞how often是問頻率(多久一次),(在這里助動詞do(does或did) 是起幫助構成疑問的作用)與一般現(xiàn)在時或一般過去時連用，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。
翻譯：“你們多久到工廠去一次?”“每星期兩次。”
“How often do you go to the factory?” “Twice a week. ”
“他們多長時間舉辦一次舞會?”“通常每兩周舉辦一次。”
“How often do they have a dancing party?” “Usually, once every other week.”
“他多久去購一次物?”“一個月一次。”
“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。”
第一個do為助動詞, 在這起幫助構成疑問的作用;而第二個do則是實義動詞。
翻譯：
What do you usually do on weekends? I often go to the movies. What does she usually do on weekends? She sometimes go hiking.
3. “What’s your favorite program?” “It’s Animal World.”
=What program do you like best?
“你最喜歡什么節(jié)目?”“動物世界。”
4. As for homework , most students do homework every day .
as for...意思是“至于;關于”，常用于句首作狀語，其后跟名詞、代詞或動詞的-ing形式(即動名詞)。如： As for him，I never want to see him here. 至于他，我永遠不希望在這里見到。
As for the story，you'd better not believe it. 關于那故事，你最好不要相信。
翻譯：至于我自己，我現(xiàn)在不想去。 (As for myself, I don’t want to go now. )
至于那個人，我什么都不知道。(As for the man, I know nothing about him.)
5. Mom wants me to get up at 6:00 and play ping-pong with her .
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：
Do you want to go to the movies with me?你想和我一起去看電影嗎?
The teacher doesn't want us to eat hamburgers.老師不想讓我們吃漢堡包。
6. She says it’s good for my health.
be good for...表示“對……有益(有好處)”;其反義為：be bad for...。(這里for 是介詞，后跟名詞、代詞或動名詞)
如：It's good for us to do more reading. 多讀書對我們有好處。
Reading in bed is bad for your eyes.在床上讀書對你的眼睛有害。
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 . 這里pretty相當于very 。
10. I try to eat a lot of vegetables , usually ten to eleven times a week .
try to do sth.表示“ 盡力做某事 ” ，不包含是否成功的意思而try doing sth.表示“(用某一辦法)試著去做某事”。
如: You’d better try doing the experiment in another way.
你最好試試用另一種方法做這個試驗。
11. My healthy lifestyle helps me get good grades.
help sb.(to) do sth.幫助某人做某事
12. Good food and exercise help me to study better.
這里better是well的比較級，而不是good的比較級
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? 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 .
keep in good health = keep healthy = stay healthy
16. You must try to eat less meat .
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
17. That sounds interesting.
這是“主語+系動詞+表語”結構的簡單句。sound(聽起來)，look(看起來)，smell(聞起來)，taste(嘗起來)，feel(覺得)，seem(好象)，grow(變得),get(變得)等詞在英語中可用作系動詞，后跟形容詞作表語。如：
It tastes good. 這味道好。
The music sounds very sweet. 這音樂聽起來很入耳。
The smoke grew heavier and heavier. 煙霧變得越來越濃了。
【詞語辨析】
一、maybe / may be
1. The baby is crying she is hungry.
2. The woman a teacher .
maybe 是副詞，意為“大概，可能，或許”，一般用于句首。May be是情態(tài)動詞，意為“可能是..，也許是..，大概是..”.
二、a few / few / a little / little
三、none / no one
none指人或物，強調數(shù)量，用how many提問，常與of連用。no one 多指人，強調“無人”這種狀態(tài)，用who提問，不可與of連用，作主語時，其謂語動詞用第三人稱單數(shù)形式。
四、hard / hardly
hard作形容詞，意為“困難的，艱苦的，硬的”;作副詞，意為“努力地，猛烈地”。Hardly意為“幾乎不”。
