        ①晚夏时节，玉米成熟了。街头做烤玉米生意的乡下人多了起来。
        ②有一天，在离我家很近的中山路上，我遇见了一个卖玉米的人。他占据着很好的地段，背靠着沃尔玛超市和工人文化宫，在过街天桥下，用一个铁皮箍起的炉子，烤着玉米。玉米被竹签穿着，一穗穗地横在炭火上。他似乎害了伤风，不时地抽着鼻子。他的生意真不错，烤好的玉米很快被路人买了去，他便剥了新的玉米，接着烤。在他旁边，摊开着一个大网袋，那里面装着至少上百穗的玉米。
       ③我不爱吃烤玉米，想买他几穗生的，回家煮。我指着他烤着的玉米问：“多少钱一穗？”
       ④“一块五。”他转动着竹签，头也不抬地说。
       ⑤“我想买四穗。”我说。
       ⑥他抬起头，问了一句：“你能吃四穗？”
       ⑦“ 我要买生的，回家去煮。”我说。
       ⑧他抽着鼻子，很干脆地说：“不卖！”
       ⑨我以为他怕我跟他讲价，于是安慰他说：“我买生的，也按一块五一穗的钱给你。”
       ⑩“那也不卖！”他坚决地说。
       ⑪这让我大惑不解。我开导他：“你卖熟的才一块五，而我买生的是一样的价，省了你的炭火，还省了你的力气，你怎么算不过来帐？”
       ⑫一听我嘲笑他不会算账，他沉下脸，指着我庄严地说：“卖给你生的，那些要吃烤玉米的人，要是不够吃了怎么办？”
       ⑬天哪，竟然是这理由！我心底里骂着他“蠢 货”，掉头而去。到了中山路革街相交的路口，我碰到了另一个烤玉米的人。这次，我以熟玉米的价钱了，顺利地买了几穗生玉米。摊主显然明白这买卖划得来，很高兴，他笑着对我说：“好吃了再来啊。”
       ⑭我提着生玉米走的时候，又遇到了那个不卖给我玉米的人。我站定了，示威性地晃悠着手中的玉米。他在招揽生意的时候，看到了我，也看到了那兜玉米，他张大了嘴，很惊恐的样子，好像的提着的，是一颗颗手雷。他别过身去，连打了几个喷嚏，然后回过头来，接着烤他的玉米，那么地安闲，那么地从容。
       ⑮夏季过去了，街上烤玉米的人都不见了。有一天路过天桥，在苍茫的蓝色中，我忽然想起了那个烤玉米的人，想起了他清瘦而黧黑的脸，以及他灵活地转动炭火上的玉米时的知足的神态。我忽然觉得他是一个身上洋溢着神灵之光的人。他为了一个信念，或者说是一种责任，拒绝唾手可得的利益，他这种固执，难道不可贵吗？
       ⑯我想，好的写作者就应该像那个玉米人那样，可以笨一点，可以放弃一点现实的利益，可以甘心承受坚持自己的信仰而带来的生意上可能的冷清。我愿意做这样一个玉米人，守着自己的炉子，守着炉子里心灵的炭火，为那些爱我作品的读者（哪怕是少数），精心焙制食粮。

    A major development to self-driving cars may change the way we will drive in the future. Google, the leading company in self-driving technology, has changed its develop plan. It had driverless cars built by car factories, but now it will start building its own cars.

    Google has started to build some kinds of experimental electric self- driving cars that look like a Smart car or Fiat 500. There is no steering wheel(方向盘), gas pedal or brake. The only things a human passenger controls are a red "e-stop" button (按钮) for fear stops and a start button. The car's only "friendly" face is designed to make it help people accept self-driving technology.

    Google workers took part in a long experiment, in which they used self-driving cars for their usual travel to work. No accident happened, but Google's heads realized that depending on a human passenger to drive in an emergency(紧急情况) wouldn't work because they may be reading, working , or sleeping. Now the self-driving car drives by itself if the driver takes his hands off the wheel for over ten seconds.

    Google recently announced that its cars had covered 700,000 miles of public roads, and they were now running in busy city streets. People who love self-driving cars say this will improve transport by making roads safer, cutting down accident, and making less pollution.

    Of course, there's no need to look for parking at a crowded shopping mall. Instead, users could let their self-driving cars drop them off to park itself. A mother who took a test ride said that having the car would allow her more time to catch up with her son. The cars could also allow people who might not be able to drive to enjoy the hand-free driving. And drunk driving? Not a problem. It is very likely that by 2020, driverless cars will be common. Do you believe so?
