as+polite+as+possible
@林空771：是as polite as possible 还是as politely as possible -
苍奇18396839783…… 都可以呀,如果动词是系动词用as polite as possible 如果动词是实义动词用 as politely as possible
@林空771：as...as possible结构中,省略号处何时用形容词何时用副词 -
苍奇18396839783…… 当前面句子中的动词是行为动词时省略号处用副词;是系动词时用形容词 因为副词修饰限定动词如 run fast,study hard,listen carefully,dance well 系动词后接形容词作表语 be important,be popular,look happy,be careful We should study as hard as possible We should be as careful as possible 所以我们应说 When we speak to people ,we should be as polite as possible
@林空771：用＂adj./adv./p.p./n.+as+主语+谓语动词,+主句＂句型造句 -
苍奇18396839783…… Small as she is,she is very polite. Fast as he runs,he won second prize. Child as he is,he is very knowledgeable
@林空771：已知{ak}数列是等差数列.(1)若m+n=p+q,求证am+an=ap+aq.(2)若ak=2k - 1,求证a12+a22+…+ak2=13k(4 -
苍奇18396839783…… 解答:证明:(1)因为{ak}是等差数列,设其首项为a1,公差为d,所以am+an=a1+(m-1)d+a1+(n-1)d=2a1+(m+n-2)d. ap+aq=a1+(p-1)d+a1+(q-1)d=2a1+(p+q-2)d. 因为m+n=p+q,所以2a1+(m+n-2)d=2a1+(p+q-2)d,所以am+an=ap+aq. (2)因为...
@林空771：抛色子的概率问题若以连续两次抛色子得到的点数a和b作为P点的坐标,则点P(a,b)落在直线x+y=6和两坐标轴围成的三角形内的概率是多少? - 作业帮
苍奇18396839783…… [答案] 一共有6X6=36个点.区域内有15点,则点P(a,b)落在直线x+y=6和两坐标轴围成的三角形内的概率是 15/36=5/12

苍奇18396839783…… 证明: 因为 (α1,α1+α2,...α1+α2+...+αs) = (α1,α2,...αs)A,A = 1 1 .... 10 1 .... 10 0 1 ... 10 0, ...., 1 由 |A| = 1 ≠ 0 知 A 可逆.所以 r(α1,α1+α2,...α1+α2+...+αs) =r[ (α1,α2,...αs)A ] = r(α1,α2,...αs) = s.所以 α1,α1+α2,...α1+α2+...+αs线性无关.其中用到一个结论: 若P可逆, 则 r(PA) = r(AP) = r(A).满意请采纳^_^.
