    【甲】秦王怫然怒,谓唐雎曰:“公亦尝闻天子之怒乎?”唐雎对曰:“臣未尝闻也。”秦王曰:“天子之怒,伏尸百万,流血千里。”唐雎曰:“大王尝闻布衣之怒乎?”秦王曰:“布衣之怒,亦免冠徒跣,以头抢地耳。”唐雎曰:“此庸夫之怒也,非士之怒也。夫专诸之刺王僚也,彗星袭月;聂政之刺韩傀也,白虹贯日;要离之刺庆忌也,仓鹰击于殿上。此三子者,皆布衣之士也,怀怒未发,休祲降于天,与臣而将四矣。若士必怒,伏尸二人,流血五步,天下缟素,今日是也。”挺剑而起。

    秦王色挠,长跪而之曰:“先生坐!何至于此!寡人谕矣:夫韩、魏灭亡,而安陵以五十里之地存者,徒以有先生也。

(节选自《唐雎不辱使命》)

    【乙】郑同北见赵王。赵王曰:“子南方之传士也,何以教之?”郑同曰:“臣南方草鄙之人也,何足问?虽然,王致之于前,安敢不对乎?臣少之时,亲尝教以。”赵王曰:“寡人不好兵。”郑同因抚手仰天而笑之曰:“兵固天下之狙喜也,臣故意大王不好也。臣亦尝以兵说魏昭王,昭王亦曰:‘寡人不喜。’臣曰:‘王之行能如许由乎?许由无天下之累,故不受也。今王既受先王之传;欲宗庙之安乎?’王曰:‘然。’‘今有人持万金之财,时宿于野,内无孟贲之威,外无弓弩之御,不出宿夕,人必危之矣。’今有强贪之国,临王之境,索王之地,告以理则不可,说以义则不听。王非战国守圉之具,其将何以当之?王若无兵,邻国得志矣。”赵王曰:“寡人请奉教。”

(选自《战国策·赵策三》,有删改)

【注】①狙:狡猾,文中指狡猾的人。②许由:尧舜时代的贤人。③孟贲(bēn):战国时期卫国人,是古代著名的武士。

    Traveling by bicycle is a very popular means of transportation throughout China. China has a huge population, and it is said that there is at least one bicycle for every two people within the country. Of course, many people in China ride bicycles purely for sport or exercise, but it's also a much more commonly accepted means of everyday transportation, as compared to countries such as the United States.

    If you are living for a long period of time in China, chances are you will want to purchase your own bicycle so that you can use it whenever you want for transportation or just for the enjoyment of riding. Even if you don't use a bicycle for everyday transportation, owning one can be a great way of enjoying some of the trails in the rural areas, just for fun. However, if you are just visiting China, renting a bicycle can be a more convenient choice.

    It is important to choose the correct bicycle for your use. You'll find that in China, the one-speed style of bicycle is extremely popular. These bicycles are great if you want to ride around in the city to see the sights. They are quite comfortable and easy to ride. You can often rent a bicycle for an entire day for around $15.

    However, if you wish to ride on some of the rural paths, a mountain bike style would be a better choice. They are great for different kinds of road surfaces, providing for a safer ride. If you are planning to have a desire to tour and still be able to carry packages with you, then a touring bike would be the best choice. These are generally the most expensive to rent, but are extremely handy for carrying packages and even some of your luggage along with you.
