[Day 677 2016-08-03]Lesson 35-1 Space odyssey
The Moon is likely to become the industrial hub of the Solar System, supplying the rocket fuels for its ships, easily obtainable from the lunar rocks in the form of liquid oxygen. The reason lies in its gravity. Because the Moon has only an eightieth of the Earth's mass, it requires 97 per cent less energy to travel the quarter of a million miles from the Moon to Earth-orbit than the 200 mile-journey from Earth's surface into orbit!
This may sound fantastic, but it is easily calculated. To escape from the Earth in a rocket, one must travel at seven miles per second. The comparable speed from the Moon is only 1.5 miles per second.
[Day 678 2016-08-04]Lesson 35-2 Space odyssey
Because the gravity on the Moon's surface is only a sixth of Earth's (remember how easily the Apollo astronauts bounded along), it takes much less energy to accelerate to that 1.5 miles per second than it does on Earth. Moon-dwellers will be able to fly in space at only three per cent of the cost of similar journeys by their terrestrial cousins.
Arthur C. Clark once suggested a revolutionary idea passes through three phases: 1 'It's impossible -- don't waste my time.'
2 'It's possible, but not worth doing.'
3 'I said it was a good idea all along.'
生詞:
1.obtainable(adj.):able to be obtained
例句:customers' finacial details are easily obtainable.
2.lunar(adj.):determined by the moon
例句:a lunar eclipse
3.orbit(n.):軌道
例句:The earth is in the orbit around the sun.
4.astronaut(n):太空人
例句:The Apollo astronauts bounded along.
5.dweller(n):a person or animal that lived in a specified spaces
例句:The majority of urban dwellers live in small apartment.
6.terrestrial(adj):地球的
例句:Increased ultroviolet radiation may disrupt terrestrial ecosystems.
點評:
hazel說:我声音洪亮,有语调和停顿eightieth 的e没出来,calculate的ca注意一下
Anda:m放在结尾的问题,容易被漏掉;oxygen英音的读法o不太一样,去查一下;escape读的不太好;five没读好~
糾正後:calculated/[ˈkælkjʊleɪtɪd];escape/[ɪsˈkeɪp] 要特別注意,然後oxygen的o要發英音版
聽到anda發comparable與錄音不太相同,後來查字典後,comparable
Pronunciation: /ˈkɒmp(ə)rəb(ə)l/,重音應該放在後頭。
課文涉及哪些訊息?太空人中,月球與地球之間的比較
表達啥意思?相對地球,月球上相關資料,像是能量消耗比、比重
我可以應用在啥場景?在理解外太空時,可以了解一些關鍵字,像是orbit,astronaut
哪些詞讓我印象深刻?The Apollo astronauts bounded along
我可以積累啥半成品?描述都市居民住的狀況
The majority of urban dwellers live in small apartments.
