有一年夏天，我从加利福尼亚州塔霍市的家乡驱车前往新奥尔良。在沙漠深处，我遇见一个年轻人站在路边。他一只手伸出拇指，另一只手拿着一个煤气罐。我开车直接从他身边经过。我认为其他人会停止。
有一年夏天，我从加利福尼亚州塔霍市的家乡驱车前往新奥尔良。在沙漠深处，我遇见一个年轻人站在路边。他一只手竖起大拇指，另一只手拿着一罐汽油。我开车从他身边经过。我想其他人会停止的。
此外，油箱只是一个掩护，停止汽车和抢劫司机。在这个国家有一段时间，如果你忽视了需要帮助的人，人们会认为你是个混蛋。如果你帮助他们，你就是个傻瓜。犯罪团伙、吸毒者、杀人犯、强奸犯、小偷和劫车犯到处潜伏。为什么要冒险呢？“我不想参加”已经成为一个国家信条。
此外，汽油罐只是阻止汽车和抢劫司机的掩护。在这个国家曾经有一段时间，如果你对需要帮助的人置之不理，你会被认为是一个混蛋。如果你帮忙，你就是个白痴。犯罪团伙、吸毒者、杀人犯、强奸犯、小偷和劫车犯到处都是，为什么要冒这个险呢？“我不想参加”已经成为全国的口头禅。
过了几个州之后，我还在想着那个搭便车的人。把他一个人留在沙漠里对我并没有太大的伤害。让我烦恼的是，做这个决定对我来说是多么容易。我的脚都没离开油门。

Hi, David,
It’s great to hear that you’re coming soon.
You can travel by plane or train. If I were you, I’d do it by plane. Why not contact a few travel agents? They sometimes offer cheap flights.
It would be worth bringing another form of identification, like an ID card, because you won’t want to carry your passport around all the time. You ought to bring a little English currency with you, in case the banks are shut when you arrive. However, it’s a good idea to have mainly travellers checks, as they’re much safer. By the way, you’ll probably find it’s well worth getting a student card — you’ll be able to get all sorts of discounts, particularly when it comes to traveling around.
There’s just one other thing — you’d better remember to get in touch with us when you’re over here, or we’ll be very upset!
Love,
Chen Bin
