In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair-weather friends. They will be with you as long as you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities(品质) of character, especially understanding, honesty and reliability(可靠).

Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person’s place, and he tries to think of ways to be helpful. He is also a good listener.

At the same time, however, a good friend is honest. He does not look for faults(过错) in others. He notices their good points. In short, a friend will try to understand me and accept me.

Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor, he will do his best to help me. If I am in trouble, he will not run away from me.

There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experiences and learn from each other. A good friend has a good sense of humor, too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

When I meet someone who is reliable, honest and understanding, I know I’ve found a friend!

(10分)一个有一定厚度的圆盘,可以绕通过中心垂直于盘面的水平轴转动,圆盘加速转动时,角速度的增加量Δω与对应之间Δt的比值定义为角加速度β(即)。我们用电磁打点计时器、米尺、游标卡尺、纸带、复写纸来完成下述实验:(打点计时器所接交流电的频率为50Hz,A、B、C、D……为计数点,相邻两计数点间有四个点未画出)

①如图甲所示,将打点计时器固定在桌面上,将纸带的一端穿过打点计时器的限位孔,然后固定在圆盘的侧面,当圆盘转动时,纸带可以卷在圆盘侧面上;

②接通电源,打点计时器开始打点,启动控制装置使圆盘匀加速转动;

③经过一段时间,停止转动和打点,取下纸带,进行测量。

(1)用20分度的游标卡尺测得圆盘的半径如图乙所示,圆盘的半径r为     cm;

(2)由图丙可知,打下计数点D时,圆盘转动的角速度为        rad/s;

(3)纸带运动的加速度大小为      m/s2,圆盘转动的角加速度大小为     rad/s2

(4)如果实验测出的角加速度值偏大,其原因可能是                 (至少写出1条)。

5月10日,国内某出口公司向捷克出口一批小商品,价值500万人民币,9月份以捷克克朗进行结算。当时人民币对美元汇率为1美元兑6.2233人民币,捷克克朗对美元汇率为1美元兑24.1780捷克克朗,则人民币和捷克克朗汇率为1人民币兑3.8852捷克克朗。9月期的人民币期货合约以1美元=6.2010的价格进行交易,9月期的捷克克朗以1美元=24.2655的价格进行交易,这意味着9月份捷克克朗对人民币的现汇汇率应为1人民币=3.9132捷克克朗,即捷克克朗对人民币贬值。为了防止克朗对人民币汇率继续下跌,该公司决定对克朗进行套期保值。由于克朗对人民币的期货合约不存在,出口公司无法利用传统的期货合约来进行套期保值。但该公司可以通过出售捷克克朗对美元的期货合约和买进人民币对美元的期货合约达到保值的目的。该交易属于()。

A.外汇期货买入套期保值

B.外汇期货卖出套期保值

C.外汇期货交叉套期保值

D.外汇期货混合套期保值
