There can be more than one answer.------more than 多余; 超过2. Tomorrow I'll be one of(……之一)the first(第一批、第一组)student s to travel in to space(去太空旅行).------one of “……之一”,该短语后面的形容词通常用最高级,名词必须用复数。
如果该结构在句子中作主语时,谓语动词用第三人称单数。
3. It'll take us to the moon. (take sb to 将某人带到,带领某人去)4. I can't wait. (can’t wait 常表达迫不及待的心情后面可以跟动词不定式等)5. The moon is around(大约)380,000 kilometres from the earth, so it'll take us about four days to get there.------It takes/ took/ will take sb. some time to do sth. 做某事花费某人多少时间6. The spaceship will leave the Earth at 9 a.m.------leave“离开”,常与介词for搭配,构成leave for sw. 结构,意思是“离开去某地”。
------leave与come, go 等趋向性动词一样,常常用进行时表达将来的意义。
7. There is no gravity in space, so we'll be able to(有能力,能够)float around in the spaceship.-----no为限定词,意为“没有,不是”,相当于not any。
There is not any gravity in space.------around 副词,“在四周,向四周,到处”,与here and there 意思相近。
------be able to do sth “能够做某事”,能用于各种时态中,时态体现在be的变化上;情态动词can 也可表“能够”,但只用于一般现在时和一般过去时两种时态,过去时用could。
8. We'll have to tie ourselves to our bed so that we won't float away in our sleep.(1)have to “不得不,必须”比较:have to 与mustA. 都有“必须”之意。
have to表示客观需要,must 表示说话人主观上的看法,即主观上的必要。
B.have to 有人称、数、时态的变化,而must只有一种形式。
C. 在否定结构中,don’t have to 表示“不必”,mustn’t 表示“禁止”。
【have to+ v表客观上“不得不做某事”,它可以用于各种时态中,其否定形式必须借助助动词构成don’t/ doesn’t/ didn’t have to 的结构,疑问句必须由do/does/did 等助动词构成。
】(2)tie…to…“把……系/ 绑/捆在……上(3)so that 意为“以便;为的是”,用来引导目的状语从句,后面常跟带can/could 的句子。
(4)float away“飘走”(5)in one’s sleep 意为“在某人的睡梦中;在某人睡着的时候”9. Without gravity, our bodies may get weak, so we’ll have to do exercises every day. ------without 是with的反义词,表示一种伴随的状态,意思是“没有……”。
注意:如果后面接某一动作,动词必须用-ing形式。
------get weak “变得虚弱”,get 这里是系动词,后接adj.,表示“变成某种状态”。
10. I'm going to take as many photos as I can, that is, if my camera still works up there.....我将拍摄尽可能多的照片,也就是说,如果我的照相机在那里还能正常运作的话……(1)take 此处意为“拍摄”,take photos “拍照”,photo为可数名词,注意它在句子中的单复数变化。
(2)as …as sb can 意为“尽某人所能”,中间可用形容词或副词原形。
(3)that is “那就是说;也就是说;即”。
常用来解释或延续某个话题。
(4)if “如果”,引导一个条件状语从句,注意句子的时态通常应遵从“主句用将来时,从句用一般现在时”的原则,当主句表达的是一个客观必然,也可以用一般现在时。
11.Buy great things such as Moon rocks and space postcards.买些如月亮石和太空明信片之类的好东西。
such as“例如,诸如此类的”,用于举例。
(1)这类结构既可以表达为such as, 也可以表达为such…as…。
如:I enjoy songs such as this one. = I enjoy such songs as this one. 我喜欢类似于这首歌的歌曲。
(2)若后面接动词,通常用动名词We are learning different English skills, such as read ing and writ ing.(3)其后不可列出前面提过的所有东西。
如:I know four languages, such as Japanese and English. (正确)I know four languages, such as Japanese, French, Chinese and English.(错误)12. at the moment= now 此时此刻;现在;目前13. Do you want to spend your holidays in hotels on the Moon------spend“花费;度过”,通常人作主语,既可以指“度过(时间)”,也可以指“花费(金钱)”,固定搭配:sb spend…on sth. 和sb spend…(in) doing sth.。
14. They will also need a large amount of air so that people there can breathe.那里还需要大量的空气,这样人们才可以呼吸。
------an amount of 意为“一定数量的”,修饰不可数名词。
a large amount of 意为“大量的”。
还可以说a small amount of“少量的”。
