“Jimmy has never seen ne，”said Mrs Andersn．“Because he's Mn-brn and can't visit Earth．[2]That's why I'm bringing ne here．I think it's the first ne ever n the Mn．”[2]“That's why...”句型，表示“那就是为什么……”。
Jimmy was ut n the crater，[3]as his mther had said．His arms and legs were lng and agile③．He lked thicker and stubbier [4]with his spacesuit n，but he culd handle the lunar gravity [5]as n Earth-brn human being culd．The uter side f the crater slped④suthward and the Earth，which was lw in the suthern sky，was nearly full，[6]s that the entire crater-slpe was brightly lit．The slpe was a gentle ne and even the weight f the spacesuit culdn't keep Jimmy frm racing up⑤it in a flating hp⑥that made the gravity seem nnexistent⑦．
[3]as引导非限制性定语从句，as指代前面主句的内容。[4]“with＋n．＋adv．”结构。[5]as引导比较状语从句。[6]s that引导结果状语从句。
“Cme n，Rbutt，”he shuted．Rbutt，wh culd hear him by radi，squeaked⑧and bunded after．Jimmy，[7]expert thugh he was，culdn't utrace⑨Rbutt，wh didn't need a spacesuit，and had fur legs and tendns⑩f steel．Jimmy culdn't g wrng while Rbutt was arund，[8]tripping⑪him when he was t near a rck，r jumping n him t shw hw much he lved him，r circling arund and squeaking lw and scared when Jimmy hid behind a rck，when all the time Rbutt knew well enugh where he was．
[7]此处是让步状语从句的倒装形式，作表语的名词提到了句首，名词前的冠词要省略。[8]三个并列的动词-ing结构作状语。
He heard his father's vice n his private wavelength⑫．“Jimmy，cme back．I have smething t tell yu．”Mr Andersn was smiling．“We have smething fr yu，Jimmy．It's at the rcket statin nw，but we'll have it tmrrw after all the tests are ver．”“Frm Earth，Dad？”

“But，Dad，we dn't knw what's inside the dg，r what his feelings are．Maybe it's just acting，t．”Mr Andersn frwned．“Jimmy，yu'll knw the difference when yu experience the lve f a living thing．”Jimmy held Rbutt tightly㉒．He was frwning，t，and the desperate㉓lk n his face meant that he wuldn't change his mind．He said，“But what's the difference hw they act？Hw abut hw I feel？I lve Rbutt and that's [12]what cunts㉔．”[12]what引导表语从句，what在该从句中作主语。
And the little rbt-mutt，which had never been held s tightly in all its existence，[13]squeaked high and rapid squeaks—happy squeaks．(Adaptatin f excerpts frm“A By's Best Friend”by lsaac Asimv)[13]“”是同源宾语现象。即：名词squeaks作动词squeaked的宾语。类似的情况还有：dream a wnderful dream，smile a sweet smile。
男孩的挚友安德森先生问：“亲爱的，吉米在哪儿？”“在外面的环形山上，”安德森太太回答道，“罗布特跟吉米在一起。它到了吗？”“是的，在火箭站，正在接受测试。自从15年前我离开地球后，就从没见过真正的狗了。”“吉米从来没见过狗。”安德森太太说。
“因为吉米是在月球上出生的，他不能去地球。所以我要带过来一只。我觉得这应该是月球上有史以来的第一只狗。”正如吉米妈妈所说，他在外面的环形山上。吉米手长脚长，行动灵活。穿着太空服的吉米虽看起来臃肿矮胖了一些，但他能承受月球引力，而在地球出生的人是不能承受这种引力的。环形山外侧向南倾斜，南面天空下方的地球全部显现出来，因此整个环形山山坡明亮了起来。山坡非常平缓，即使吉米穿着厚重的太空服，也不能阻碍他跳着跃向山坡，就好像引力不存在一样。
“快过来，罗布特。”他大喊。靠电波辨认声音的罗布特发出叫声，跳着跑向吉米。论速度，吉米虽然是个能手，但他比不过罗布特，因为它有四条腿和钢铁做的肌腱，还不用穿太空服。只要有罗布特相伴，吉米就没有危险。当吉米过于靠近一块岩石，它会扑倒他；罗布特还会扑向他，以表达爱意；当吉米藏在岩石后，罗布特就原地打转，低吼，战战兢兢，不论什么时候，罗布特都对吉米的位置了如指掌。
吉米通过自己的专属波长接收到了爸爸的声音，“吉米，回来一下。我有事情要和你说。”安德森先生面带微笑，“吉米，我们有东西要给你，它现在就在火箭站，但是要等到明天所有测试结束后，我们才能接到它。”“是从地球来的吗，爸爸？”
“是从地球来的小狗，儿子，是月球上的第一只狗。你将不再需要罗布特了。我们不能同时要两只，其他的孩子会收养罗布特。”他好像在等吉米说点什么，接着又说，“你会知道什么才是真正的狗，吉米。狗是有生命的。罗布特仅仅是机械仿制品，是一只机器狗罢了。所以它才叫罗布特。”吉米皱皱眉头，“爸爸，罗布特不是仿制品。”“罗布特只是用钢铁和电线制造的，只有一个简单的正电子大脑。”
“爸爸，我想让它做什么，它都能做到，它懂我。”“不是这样的，儿子。罗布特只是一个机器。它的反应只不过是按照编好的程序去做而已。真正的狗是有生命的。等小狗来了，你就会明白二者的不同之处了。”吉米看着又在吼叫的罗布特，它的叫声非常低沉缓慢，好像受到了惊吓。吉米伸出双臂，罗布特一跃，跳了上去。吉米问：“那罗布特和真正的小狗有什么不一样呢？”
“这很难解释。”安德森先生说，“但用眼睛看的话，会很容易。小狗会真的爱你，而罗布特只是设定好，假装很爱你。”“但是，爸爸，我们并不知道小狗真正想的是什么，它是什么感觉。可能它也只是在假装。”安德森先生眉头一皱，“吉米，如果你体验过一个生命体对你的爱时，你就会明白其中的不同。”吉米紧紧抱着罗布特。他也皱着眉头，脸上的坚定表明他不愿改变心意。他说：“那它们在行为上有什么不一样？那我的想法呢？我爱罗布特，我觉得这是最重要的。”
小小的机器狗自出现以来从未被抱得那么紧，它发出尖细且急促的叫声，那是快乐的叫声。(节选自艾萨克·阿西莫夫的《男孩的挚友》)
