用友报表系统中，报表公式定义包括( )。 A．计算公式 B．审核公式 C．舍位平衡

如图所示，质量M="3.5" kg的小车静止于光滑水平面上靠近桌子处，其上表面与水平桌面相平，小车长L="1.2" m，其左端放有一质量为m₂="0.5" kg的滑块Q。水平放置的轻弹簧左端固定，质量为m₁="1" kg的小物块P置于桌面上的A点并与弹簧的右端接触。此时弹簧处于原长，现用水平向左的推力将P缓慢推至B点(弹簧仍在弹性限度内)时，推力做的功为W_F，撤去推力后，P沿桌面滑动到达C点时的速度为2 m/s，并与小车上的Q相碰，最后Q停在小车的右端，P停在距小车左端S="0.5" m处。已知AB间距L₁="5" cm，A点离桌子边沿C点距离L₂="90" cm，P与桌面间动摩擦因数μ₁=0.4，P、Q与小车表面间动摩擦因数μ₂=0.1。(g="10" m/s。)求：

(1)推力做的功WF；

(2)P与Q碰撞后瞬间Q的速度大小和小车最后速度v.

孔子尝日∶“未知生，焉知死”生与死自孔子时起便是中国人始终关注的问题，并得到各种回答。尤其在汉代，人们以空前的热情讨论这两个问题，不仅是出于学者的学术乐趣，亦出于普通民众生存的需要。然而，正如孔子所说，在中国思想史上，对生的问题的关注似乎远胜于对死的问题的追问。有时候人们确实觉得后者更重要，但这并非由于死本身，而是因为人们最终分析认为，死是生的延续。 这段文字的核心观点是( )。

A．孔子关于生死的看法对中国人产生深远影响

B．生与死是中国思想史上长期受到关注的问题

C．中国人对生与死的问题的讨论实际以生为旨归

D．对生死问题的不同答案源自讨论者的不同观念

When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.

When I was in the eighth grade, I had a friend. We were shy and "too serious" about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say: "Let’s start with a train whistle today." We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we were changing into social creatures and the stories and poems stopped.

When I lived for a time in London, I had a friend, he was in despair and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.

For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:"Yes, I must tell..." We have never met.

It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist,who will only fill up the healing silence necessary to those darkest moments in which I would rather be my own best friend.

According to paragraph 4, the author and her friend（）.

A. call each other regularly

B. have similar personalities

C. enjoy writing to each other

D. dream of meeting each other
