参考答案

II. 1. 本题为细节推断题。由第一段前两句话可知，观夜空会看见很多星星，而每一颗星都能通过核聚变产生大量的能量，作者将星星比喻成了“发电厂” ，故C为正确答案。

2. 本题为逻辑推理题。由第二段doubled a world record set in 1997… make the same amount of energy as four wind turbines make可知本次实验是1997年的两倍且与四个涡轮机产生的能量同量，故选C。

3. 此题为细节信息题。由第四段This problem can be solved with cooling systems可知，冷却系统可以解决设备因过热而停止的问题，故B为正确答案。

4. 本题为归纳主旨题，本段是在回答这段的第一句话”why do we care so much about star power?”，亦是核聚变反应的优势，故A为正确答案。

5. 本题为归纳判断题，由文意可知，该实验历经数年虽然有最新的进步，但因条件要求高而影响进程，只有B选项陈述相符。

IV. A: 1. energies 2. set 3. experiment 4. landmark 5. conditions

B: 1. 北京为奥运会投入了大量资金。
