You might say that someone is "hedging his bet" when he invests in several different kinds of businesses. One business may fail, but likely not all. 如果某人在多门不同类型的生意上分别投资,你可能会说他是在双面投机(hedging his bet).生意可能会亏损,但不可能全部都亏损. Farmers know that it is necessary to "make hay while the sun shines."____________________ 农民们都知道,把握时机(make hay while the sun shines)是非常必要的.
