2. At present, ur spacecraft are t slw t carry large numbers f passengers t Mars—it wuld take mnths. 目前, 我们的宇宙飞船太慢了, 无法运送大批的乘客去火星——因为要花费几个月的时间。
large numbers f（大量的）=a large number f，修饰可数名词复数形式；
a number f=numbers f 许多、大量, 用来修饰可数名词复数，作主语时，谓语动词用复数形式。
拓展：the number f … ……的数量，作主语时谓语动词用单数形式。

4. The gravity n Mars is nly abut three-eighths f that n the Earth.
火星上的重力大约只有地球上的八分之三。
(1)分数表达法：
分子是基数词，分母是序数词，如果分子大于1，分母要用复数形式，在分子与分母之间可加连字符也可不加连字符。
“分数+f+名词”结构作主语时，谓语动词的单复数视f后面的名词而定，如果名词是复数，谓语动词用复数形式；如果名词是单数或不可数名词，谓语动词用单数形式。
Tw thirds f the land is cvered with water.三分之二的陆地被水覆盖。
One fifth f the students cme frm the cuntryside.

在作比较时，我们常用that/thse指代句中类似或相同的那一部分。通常that用于指代可数名词单数或不可数名词， thse用于指代可数名词复数。此句中的that指代前面的gravity。

specially adv. 专门地，特地 ,强调唯一目的。
He came here specially t say srry t her. 他特意来这里向她道歉。
(2) prevent v. 阻止
prevent sb frm ding sth 阻止某人做某事
动词prevent也可以换成stp或者keep。
stp…(frm) ding=keep…frm ding
stp/prevent后的frm可以省略。
Yu must prevent the kids (frm) playing with fire.
=Yu must stp the kids (frm) playing with fire.
=Yu must keep the kids frm playing with fire.
你必须阻止孩子们玩火。
6. Cmpared with life n the Earth, life n Mars wuld be better in sme ways.与地球上的生活相比，火星上的生活在某些方面要好些。
(1) cmpared with life n the Earth 过去分词短语作状语, cmpare放在句首作状语时，表示被动要用cmpared，表示主动要用cmparing。
Cmpared with many peple, she is really lucky.
和许多人相比，她真的很幸运。
Cmparing this bk with that ne, she fund this ne is better.

in ne’s way挡了某人的路 (in) this way 用这种办法
by the way顺便说一下 n way 没门儿, 不行
7. Every student wuld have a cmputer at hme cnnected t an interplanetary netwrk.每个学生家里都有一台电脑与星际网络相连接。

First cnnect the printer t the cmputer.首先把打印机与计算机连接起来。
This pipe cnnects with the sewer.这条管子连着下水道。
(2)本句中的cnnected t…是过去分词作定语,相当于一个定语从句which is cnnected t..., 即所限定名词是从句谓语动作的对象。
8. Life n Mars wuld be interesting as well as challenging.
火星上的生活，不仅有挑战性，还很有趣。
as well as 既……又……，当as well as与主语连用时，在意义上强调前者，谓语动词应与其前的主语保持一致。
