For this part, you are allowed 30 minutes to write an essay explaining why it is unwise to put all your eggs in one basket. You can give examples to illustrate your point. You should write at least 150 words but no more than 200 words.

It is a truth universally acknowledged that we need to have a plan B when making crucial decisions or important plans. As an old saying goes, it is unwise to put all your eggs in one basket. This saying obviously aims to deliver the message that in order to avoid possible failures and setbacks, having a second choice is essential.

Nobody can be certain of what is going to happen in the future; therefore, we all need to have different plans and preparations in case of undesirable outcomes. Then, the losses and risks can be tremendously reduced. 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.

To conclude, it is highly unfeasible to put all eggs in just one basket. Not only will this give rise to the unexpected and unaffordable result, but we will be inclined to be irrational and unreasonable.

参考译文

我们需要在制定关键决策或重要计划时制定一个备用计划，这是一个普遍承认的事实。俗话说，把所有的鸡蛋放在一个篮子里是不明智的。这句话显然是要告诉我们：为了避免可能的失败和挫折，第二选择是至关重要的。

没有人可以肯定将来会发生什么事情;因此，为了避免不良结果，我们都需要有不同的计划和准备。那么损失和风险就可以大大降低。例如，随着房地产市场现在的高利润，许多人将所有的钱投入去买新房，有的甚至贷款买房。可能的结果是，一旦市场冷却，房价下跌，投资者更有可能失去他们的利润和资本。

总而言之，将所有鸡蛋放在一个篮子里是非常不可行的。这不仅会造成意想不到的难以估量的结果，而且我们也会被看作不理性的。

根据题目要求，我们可以列出以下提纲：

第一段：引出名言，揭示寓意。

第二段：介绍原因，举例说明。

第三段：总结全文，提出建议。
