When making crucial decisions or important plans, it is always necessary to have a plan B. As the old saying goes, "Never put all your eggs in one basket." Having a second choice is essential to reducing the loss.
　　It is easy to understand that, for any plan that involves investments beforehand, one should prepare for the worst situation no matter how well it appears currently. When the profits are higher, people are also taking greater risks. For example, as the real-estate market is highly profitable nowadays, many people invest all their money into new houses and some even raise a mortgage. The possible result is that once the market cools down and the house prices go on a decrease, the investors are more likely to lose the profits as well as the capital. Admittedly, putting all the eggs in one basket maximizesthe possible gaining. However, in unfavorable conditions, it also maximizes the loss.
　　In conclusion, it is unwise to put all your hopes into one possible solution. People should all learn the importance of avoiding risks with a plan B.

　　【点评】
　　题解：“把所有鸡蛋放在一个篮子里是不明智的。”
　　本题难度中上，讨论风险与机会的关系，以及减少风险的方法，较抽象。
　　文章可采取三段式。首段简单阐述话题含义。主体部分重点论述“把所有鸡蛋放在一个篮子里”可能带来的风险。由于话题较抽象，此处可用具体的事例论述，证明在有一定风险的情况下，人们不应该将所有的希望都集中在同一个解决方案中，而是应该有备用方案，以减少风险。结论部分重述主题。
