English food has a bad reputation abroad. This is most probably because foreigners in England are often obliged to eat in the more “popular” type of restaurant. Here it is necessary to prepare food rapidly in large quantities, and the taste of the food inevitably suffers, though its quality, from the point of view of nourishment, is quite satisfactory.  Still, it is rather dull and not always attractively presented. Moreover, the Englishman eating in a cheap or medium price restaurant is usually in a hurry—at least at lunch—and a meal eaten in a leisurely manner in pleasant surroundings is always far more enjoyable than a meal taken hastily in a business-like atmosphere. In general, it is possible to get an adequate meal at a reasonable price; in fact, such a meal may be less expensive than similar food abroad. For those with money to spare, there are restaurants that compare favourably with the best in any country.

橐驼非能使木寿且孳也,能顺木之天,以致其性焉尔。凡植木之性。,其本欲舒,其培欲平,其土欲故,其筑欲密。既然已,勿动勿虑,去不复顾。其莳也若子,其置也若弃,则其天者全而其性得矣。故吾不害其长而已,非有能硕茂之也;不抑耗其实而已,非有能早而蕃之也。他植者则不然:根拳而土易;其培之也,若不过焉则不及。苟有能反是者,则又爱之太殷,忧之太勤,旦视而暮抚,已去而复顾。甚者爪其肤以验其生枯,摇其本以观其疏密,而木之性日以离矣。虽日爱之,其实害之;虽日忧之,其实仇之:故不我若也。 ——选自《种树郭橐驼传》 郭橐驼种树的基本原理是什么?
