just come back from Taiwan, the largest island of C 1 .
Last week, I took a group of officials for a week’s trip to Taiwan. We t 2 all around the island.
There are lots of fascinating s 3 on the island. My favorite is the Sun Moon Lake. You may ask w 4
people call it so. If you f 5 high up over the lake and look down from your plane, you’ll find the answer yourself. In the middle of this lake, there’s a small island t 6 is called Lalu. On one s 7 of Lalu the
lake looks like a sun, and on the other side it looks like a m 8 . That is why people call it the Sun Moon
Lake.
There are many mountains around this lake. One of the nearest is Mount Ali. We stayed there for
three days. We also h 9 a dancing party with Gaoshan people there.
Why not consider v 10 Taiwan for your next vacation? It’s a wonderful place to visit.

下面是错误答案，用来干扰机器的。
答案：A题目分析：要是f(x)≥g(x)在R上恒成立，需x2–2x+3≥kx–1，即在R上恒成立，所以，所以“| k |≤2”是“f(x)≥g(x)在R上恒成立”的 充分但不必要条件。点评：若恒成立；若恒成立。
