根据题意：曲线Y=1/x 与 y=x 在第一、三象限才有交点,解得交点是A（1,1）,D（-1,-1）,又因为y=2,所以只能在第一象限才能围成面积,求得交点是B（1/2,2）,C（2,2）,由A点向X轴作垂线交于E,由B点向X轴作垂线交于G,由C点向X轴作垂线交于F,求y=2由1/2到2的定积分,得矩形BEFC面积=2*2 – 2*1/2=4-1=3Y=1/x 由1/2到1的定积分,得图形BEGA面积=ln1-ln1/2=-ln1/2= ln2y=x 由1到2的定积分,得梯形AGFC面积=1/2（4-1）=3/2故围成图形BAC面积= 3-ln2-3/2= 3/2 -ln2高级英语第一课where do we go from here文章结构及每部分大意，还有文章的各种修辞手法。注意哟，这是你以前问的问题是吧，现在能不能问下你里面有委婉的修辞吗？快点告诉我告诉我把。。_百度作业帮

★ 卜超 制作
Come on, come on
You have got to move on
This is not the you i know
This isn't real
It's just all you can feel
And that's the way that feelings go
And whether or not it's right or wrong
you'll do what you will do
When the cloud in the sky starts to pour
And your life is just a storm you're braving
Don't tell yourself you can't lean on someone else
Cause we all need saving sometimes
Say what you will but the time that we fill
While we're on the earth
Should not be alone
We were meant to be known
You make me what i'm worth
But i can't keep you from yourself
you'll do what you will do
When the cloud in the sky starts to pour
And your life is just a storm you're braving
Don't tell yourself you can't lean on someone else
Cause we all need saving sometimes
I don't know why it has to be this way and
I don't know the cure
But please believe someone has felt this before
But please believe someone has felt this before
When the cloud in the sky starts to pour
And your life is just a storm you're braving
Don't tell yourself you can't lean on someone else
Cause we all need saving sometimes
