初中英語表示量的詞

初中英語表示量的詞

英語中沒有量詞
要表示只能用數詞或冠詞
eg:a car/desk一輛小車/一張課桌
two cups of tea兩杯茶
a piece of new一則新聞
one
數詞+表示量的名詞+of句型中,形容詞應加在哪?
例如a pair of pants,如果想改成一條藍色的褲子,藍色應加在哪?所有都是這樣的嗎?
a pair of blue pants
a pair of後面的名詞可以用形容詞修飾,形容詞常常放在pair之後
有不懂可以找我.
a pair of blue pants
a pair of後面的名詞可以用形容詞修飾,形容詞常常放在pair之後
希望幫到你。
LS的回答都對,a pair of blue pants,修飾詞(adj)應該放在名詞pants的前面作定語。
其實如果你對語法不是很清楚的話,還有一個小竅門,就是按照咱們漢語的語法來做。
一條藍褲子,一條是a pair of,褲子的pants,按照順序,藍必然要放到pants的前面拉!
這樣記是不是很簡單呢?
其實很多問題都可以圍繞咱們漢語的語法做記憶,慢慢的你就…展開

其實很多問題都可以圍繞咱們漢語的語法做記憶,慢慢的你就覺得英語的語法其實很簡單,根本沒有漢語難的~
希望能幫到你哦!收起
英語中表示最後的詞和片語!
如:finally,at last,in the end
越多越好啊!
lastly:adv最後;終於e.g:Lastly,I must point out that…最後,我要指出的是…ultimately:adv最後;最終e.g:We hope ultimately to be able to buy a house of our own.我們希望最終能够自己買一所房子.eventual…
finally=at last=in the end
錶最後,最終
in th end最後
at last最後
英語中用於表示“因為”的詞和片語及其用法
希望越多越好!!

Middle English
中古英語
*See Also:because of
A traditional rule holds that the construction the reason is because is redundant,and should be avoided in favor of the reason is that. The usage is well established,however,and can be justified by analogy to constructions such as His purpose in calling her was so that she would be forewarned of the change in schedule or The last time Isaw her was when she was leaving for college. All three constructions are somewhat less than graceful,however.·When because follows a negated verb phrase,it should be preceded by a comma when the because clause explains why the event did not occur. He didn't marry her,because she was frivolous means roughly,“Her frivolity was his reason for not marrying her.”When no comma is used,the because clause is understood as part of what is being negated. He didn't marry her because she was frivolous means roughly,“His reason for marrying her was independent of her frivolity.”
傳統的原則認為結構the reason is because太累贅,應避免,而贊同使用the reason is that .這種用法被廣泛地接受,並可以用類似的結構證明是正確的,如他呼喚她的目的是以便她能預先知道時間安排的改變,或者最近一次我看見她是當她正要去學院時.然而所這三種結構都有不够完美的地方.當because跟著一個否定動詞短語時,該在它前面加一個逗號來表示這個because從句解釋的是為什麼這件事沒有發生.他不娶她,因為她很輕浮.粗略的意思是,“她的輕浮是他不娶她的原因.”當沒有用逗號時,這個because從句被理解為被否定的部分.他不娶她不是因為她輕薄,粗略的意思是,“他和她結婚的原因與她的輕薄無關.”

如圖,已知A,B,C是數軸上的三點
動點P,Q同時從A,C出發,分別以每秒六個組織和三個組織的速度沿數軸正方向運動.M為AP中點,N在CQ上,且Cn=三分之一倍的CQ,設時間為t(t>0).t為何值時,原點O,P.Q三點鐘,有一點恰好是另兩點所連線段的中點
------------------------------------------------
A O B C→
以題意知:A=-10 C=6 B=2
動點P=-10+6t
Q=6-3t
M為AP中點所以M=(-10-10+6t)/2 =-10+3t
N=(6-3t+6)/2 =6- 3/2 t
O為PQ中點所以(M+N)/2=0 M+N=0即-4+3/2 t=0
解得t= 8/3秒
定義域為R的奇函數y=f(x)為减函數,且f(cos^α+sinα)+f(2m)>0恒成立,求m的範圍
f(cos^α+sinα)+f(2m)>0
所以,f(cos^α+sinα)>-f(2m)=f(-2m)
因為f(x)為减函數
所以,cos^α+sinα2m+5/4
因為-1
求y=log1/2X的反函數
你這1/2是底數?
那麼反函數就是y=(1/2)^x
對數函數和指數函數互為反函數
D已知數軸上有三點A.B.C,AB=1/2AC,點C對應的數是200.(1)BC=300,求A點對應的數.(2)在(1)的條件下
動點P,Q分別從A.C兩點同時出發向左運動,同時動點R從A點出發向右運動,點P,Q,R的速度分別為10個組織/秒,5個組織/秒.2個組織/秒,點M為線段PR的中點,點N為線段RQ的中點,多少秒後恰好滿足MR=4RM(不考慮點R與點Q相遇後的情形)
(1)B -100
(2)MR=4RM?題目打錯了吧
設定義域為R的奇函數f(x)是减函數,若當時0
f(cos^2a+2msina)+f(-2m-2)>0
f(cos^2a+2msina)>-f(-2m-2)
f(cos^2a+2msina)>f(2m+2)利用奇函數右式變形
cos^2a+2msina2-cos^2a/sina-1
再通過變形得到2m>(sina-1)+2/(sina-1)+2
該式要成立,只要左式大於右式的最大值即可,故轉求右式最大值,明顯右式為對號函數複合形式,由影像得最大值-1
則左式2m>-1即可
則m>-1/2
已知f(x)是定義在R上的奇函數,當x
x=(1/2)^(f^-1(x))
f^-1(x)=log(1/2)(x)=-log 2(x)(x>1)
=log2(-x)(x
