1. There are numerous products which may be said not to admit of being consumed otherwise than unproductively. 有很多产品，可以说除作非生产性消费外别无他用。
2. Much of the foreign money it has attracted has gone into inflating share prices or just accumulated unproductively in foreign reserves. 许多吸收进来的外资要么就是把股价推高，要么就是作为外汇储备躺在那里。
3. The length of our life time is measured by what we have achieved during our life. Therefore, we shall compete against time and do not let it slip by unproductively. 一个人在世间做了多少事就等于寿命有多长。因此，必须与时日竞争，切莫使时日空过。
