5) doubtful; negative

Reading and Discussing

3. For reference

1) Due to the energy shortage on earth, it’s essential for human beings to explore other planets, e.g., Mars. For our survival in the future, perhaps we have to be a multi-planet species.

2) Space exploration requires humans to be able to travel long distances through space and survive in space for long periods of time. The demands of even beginning to explore these possibilities test humans’ ph ysical, psychological and technological mettle. Pushing further into space exploration means overcoming huge costs, technical problems, the limitations of the human body and the uncertainties of space itself.

即使加里奥特对颇值得称道的马斯克项目信心满满，其中也还有模糊不清的成分。他之所以如此热情，部分是因为马斯克的太空探索技术公司这周刚刚宣布其蚱蜢机型第三轮测试成功。这种机型采用单片助推器和机组舱，可以像长腿的火箭一样升空和降落。但是这种机型只能达到240英尺（80米）的高度，且飞行速度不快。自从人类有了飞入太空的梦想，航天工程师就一直研发着单极入轨飞行器，犹如人类对冷聚变和永动机的执著追求一样，但迄今仍无人成功。这并不意味着马斯克也做不到，他或许可以，但这确实意味着，仅仅一次240英尺的测试难以承受太空飞行的梦想就能实现之重。加里奥特宣称，蚱蜢

机之类的航天飞机只比传统的一次性助推器多消耗10%的燃料，这一说法让人

难以信服。

9. Reference translation

At the Jiuquan Space Center, Shenzhou 5 is scheduled to blast into orbit atop a Changzheng (“Long March”) rocket. But unlike those four unmanned Shenzhou test spacecrafts which have already made orbital flights, Shenzhou 5 is expected to carry a crew of up to three young pilots, which will make China the third nation to send people into space. Although representatives of three dozen countries have gone into orbit since the dawn of the space age, they have all traveled aboard either American or Russian spacecraft. China’s space agency, however, built several key systems on its own, and in some ways the Shenzhou is technologically superior to the Soyuz.
