2) Natural fiber is said to be superior to synthetic fiber.
我很快意识到，这件小事与我们在中国要做的工作直接相关：考察儿童早期教育 (尤其是艺术教育)的方式，揭示中国人对创造性活动的态度。因此，不久我就在与中国教育工作者讨论时谈起了钥匙槽口一事。
两种不同的学习方式
我的中国同行，除了少数几个人外，对此事的态度与金陵饭店工作人员一样。”既然大人知道怎么把钥匙塞进槽口——这是处理槽口一事的最终目的， 既然孩子还很年幼，还没有灵巧到可以独自完成要做的动作，让他自己瞎折腾会有什么好处呢?他很有可能会灰心丧气发脾气——这当然不是所希望的结果。为什么不教他怎么做呢?他会高兴，他还能早些学会做这件事，进而去学做更复杂的事，如开门，或索要钥匙——这两件事到时候同样可以 (也应该)示范给他看。
3) The city’s importance as a financial center has evolved slowly.
4) His nationality is not relevant to whether he is a good lawyer.
5) The poems by a little-known sixteenth-century Italian poet have found their way into some English magazines.
创造力第一?
从对创造力的态度来说，优先次序似乎是颠倒了：西方的年轻人先是大胆创新，然后逐渐深谙传统；而中国的年轻人则几乎离不开传统，但是，随着时间的推移，他们同样可能发展到具有创新的境界。
