過去:生活條件差、道路狹窄、車輛少、住不好、吃不飽、聯系簡單、慢.
現在:生活條件優越、道路寬、車輛多、住的舒適、手機普及.
n the past: poor living conditions,narrow roads,vehicles less,live well,enough to eat,contact a simple,slow.
Now: excellent living conditions,road width,vehicles,live in comfort,cell phone popularity.
在疑問句中,動詞含有現在進行時的形式嗎
在動詞後面的前提下
有!比如:I am cleaning the room.一般疑問句:Are you clening the room?在疑問句中,動詞含有現在進行時的形式
下列四個函數中為週期函數的是
1.y=3
2.y=3x°(注意是度數)
3.y=sin|x|,x∈R
4.y=sin(1/x),x∈R且x≠0
1.
第一個,以任意數為週期
問題補充:A y=tanx B y=sin絕對值x c y=cos2x d y=絕對值sinx d y=絕對值sinx
現在進行時陳述句變特殊疑問句,動詞要變原形麼
What are you doing?你看這個是東西原型嗎?
最後不是doing嗎?
看來是不要用原形的
下列函數中,週期為π,且在[π4,π2]上為减函數的是()
A. y=sin(2x+π2)B. y=cos(2x+π2)C. y=sin(x+π2)D. y=cos(x+π2)
C、D中函數週期為2π,所以錯誤當x∈[π4,π2]時,2x+π2∈[π,3π2],函數y=sin(2x+π2)為减函數而函數y=cos(2x+π2)為增函數,故選A.
Be動詞還原,並改為一般疑問句
1.the pen's my brother's
2.that's liu's sister
3.Anna's Jim's sister
4.the pen's miss jin's
5.my mother's handbag's yellow and white
6.it's helen's grandma's glass
1.The pen is my brother's.
問:Is the pen your brother's?
2.That is Liu's sister.
問:Is that Liu's sister.
3.Anna is Jim's sister.
問:Is Anna Jim's sister?
4.The pen is Miss Jin's.
問:Is this Miss Jin's pen?
5.My mother's handbag is yellow and white.
問:Is your mother's handbag yellow and white?
6.It is Helen's grandma's glass.
問:Is it Helen's grandma's glass?
1.Is the pen your brother's?
2.Is that Liu's sister?
3.Is Anna Jim's sister?
4.Is the pen miss Jin's?
5.Is your mother's handbag yellow and white?
6.Is it Helen's grandma's glass?

2.That is Liu's sister.->is this Liu's sister?
3.Anna is Jim's sister.-> is Anna Jim's sister?
4.the pen is miss jin's->is the pen mis…展開
1.The pen is my brother's.-> Is the pen my brother's?
2.That is Liu's sister.->is this Liu's sister?
3.Anna is Jim's sister.-> is Anna Jim's sister?
4.the pen is miss jin's->is the pen miss jin's?
5.my mother's handbag is yellow and white->Is my mother's handbag yellow and white
6.it is helen's grandma's glass.-> is it helen's grandma's glass?收起
Is the pen your brother's?
Is that Liu's sister?
Is Anna Jim's sister?
Is the pen Miss Jin's?
Is your mother's handbag yellow and white?
Is it Helen's grandma's glass?
注意be動詞縮寫和名詞所屬格的區別
在R上,下列函數中為週期函數的是
A sin(e^x)
B e^sinx
C xcosx + tanx
D arcsinx + arccosx
請說明下原因
我開始選的是D,但是答案是B
我不明白,請多指教
sinx是週期函數,所以e^sinx自然也是週期函數
至於D,arcsinx + arccosx =派/2是常函數,一般不認為是週期函數
更重要的是,D的定義域不是R,而是在(負派除2,派除2)
D是常數函數
現在進行時的句子怎樣改為一般疑問句,一般疑問句是用助動詞開頭,還是用be動詞開頭?
be動詞提前
下列函數中最小正週期為2π的是
A.y=sin²;x
B.y=sin|x|
C.y=|cos(x/2-π/3)|-1/2
D.y=sinx/1+cosx
A、周期π
B、周期π
C、週期2π
D、週期2π
D
D
Ta=π
Tb=π
Tc=4π
老師不是說過有sin(nx)或者cos(nx)之類的最小正週期是π/n嗎,囙此你認真將各個選項變形就可以得出答案了;B選項的可以通過畫圖得出是π……
好好看書就會做咯,加油啊。我也差不多忘了,呵呵
