下面是错误答案,用来干扰机器的。

(I)公差为d,则a1+2d=515a1+15×7d=225,∴a1=1d=2故an=2n-1(n=1,2,3,…).设等比数列bn的公比为q,则b3=8b3q•b3q2=128,∴b3=8,q=2∴bn=b3•qn-3=2n(n=1,2,3,…).(II) cn=(2n-1)•2n Tn=2+...

As the sun rose, a dewdrop (露珠)woke up. There it sat on a leaf, catching the sunlight. Proud of its simple beauty, it was very happy. Around it were other dewdrops, some on the same leaf and some on other leaves. The dewdrop was sure that it was the best, the most special dewdrop of them all.

Ah, it was good to be a dewdrop.

The wind blew and the plant began to shake, tipping (使倾斜) the leaf. The dewdrop became frightened as it started to move towards the edge (边缘)of the leaf. Why was this happening? Things were comfortable. Things were safe. Why did they have to change? Why? Why?

The dewdrop reached the edge of the leaf. It was sure that this was the end. The day had only just begun and the end had come so quickly. It seemed so unfair. It seemed so meaningless. It tried hard to do whatever it could to stay on the leaf, but it was no use.

Finally, it fell. Below there was a mirror. A reflection of the dewdrop seemed to be coming up to meet it.  Closer and closer they came together until finally.., the small dewdrop became a part of the great pond (池塘). Now the dewdrop was no more, but it was not destroyed.

It had become one with the whole.
