They think Rbutt is just a machine.
Q2: 2) If yu were Jimmy, which ne wuld yu chse, Rbutt r a real dg?

1. The uter side f the crater slped suthward and the Earth, which was lw in the suthern sky, was nearly full, s that the entire crater-slpe was brightly lit.
Paraphrase: The entire crater-slpe faced suth and was brightly lit by the sun’s reflectin n the Earth, which was just abve the hrizn t the suth.
1) 句子结构分析:① 首先看清句子的大结构，是 and 连接的两个并列句，第一个并列句是 The uter side f the crater slped suthward，第二个并列句的主干是 the Earth was nearly full。② 第二个并列句的主语 the Earth 后面紧跟了个由 which 引导的非限制性定语从句，which 指代的是 the Earth。③ 第二个并列句中还包含一个 s that 引导的结果状语从句。
She leaned frward and kissed him n the cheek.
① suthward 是副词，意为“向南方”，以 –ward 结尾的词都有“向……方向”的意思，如 frward 意为“向前”
练习：她倾身向前，吻了他的面颊。
② which 引导的非限制性定语从句对先行词或主句起到补充说明的功能，不起到“限定”作用。
（which 引导的非限制性定语从句是对主句进行补充，非限制性定语从句若去掉，不影响主句的意思完整。）
例如：He didn’t pass the exam , which disappinted me.
③ s that 在此引导的是结果状语从句，意为 “因此，所以”。 例如： I tk n ntice f him, s that he flew int a rage.我没注意到他，他因此大发雷霆。
He practices speaking English every day, s that his spken English is fluent.
辨析: s that 后面也可接目的状语从句，此时 s that 后面的从句多有 can / culd / may 等词, 意为 “目的是”。例如：The ld man takes mre exercise s that he can live lnger.
练习：他每天都练习说英语，因此口语非常流利。
2. The slpe was a gentle ne and even the weight f the spacesuit culdn’t keep Jimmy frm racing up it in a flating hp that made the gravity seem nnexistent.
Paraphrase: Jimmy was able t bund easily up the gentle slpe, hardly nticing the weight f his spacesuit because f the Mn’s lw gravity.
句中有 keep sb. frm ding sth 这个短语，意为 “阻止某人做某事” , 相当于 stp sb. frm ding sth。
练习：我们要采取措施阻止这样的事情再次发生。
We have t take measures t keep this kind f thing frm happening again.
例如：These wrries kept her frm sleeping prperly.这些烦恼使她睡不好觉。
2) flat v. 浮动；漂浮；飘动；飘移；使漂流
3) hp n. 单足蹦跳；单足短距离跳跃；短途旅行
A plastic bag was flating in the water.一个塑料袋在水中漂浮。

3. Jimmy culdn’t g wrng while Rbutt was arund, tripping him 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.
Paraphrase: Jimmy was always safe while Rbutt was with him. Rbutt wuld knck him ut f truble when he was t near a rck, jump n him t shw hw much he lved him, r g rund in circles making nises as if he was scared when Jimmy hid behind a rck. Rbutt always knew very well where Jimmy was.
1) 此句中的 tripping … a rck, jumping … lved him, circling arund and squeaking … where he was 为四个并列的 ding 结构，在句子中作 was arund 的伴随状语。
2) 此句中的 trip 意为 t make smene fall by putting yur ft in frnt f them when they are mving “把（某人）绊倒”
例如： He didn’t ntice me and stretched ut his ft suddenly, almst tripping me.他没注意到我，突然伸出脚，差点把我绊倒。
4. Jimmy held ut his arms and Rbutt was in them in ne bund.
Paraphrase: When Jimmy pened his arms, Rbutt jumped int them at nce.

Yu’ve dne s much wrk ─ yu’re bund t pass the exam.你下了这么大工夫，考试绝对没问题。
