科学研究表明，大量吃鱼可以大大减少患心脏病的危险，这里起作用的关键因素是在鱼油中所含的丰富的“奥米加一3”脂肪酸。因此，经常服用保健品“奥米加一3”脂肪酸胶囊将大大有助于你预防心脏病。以下哪项如果为真，最能削弱题干的论证

A．“奥米加一3”脂肪酸胶囊从研制到试销，才不到半年的时间。

B．在导致心脏病的各种因素中，遗传因素占了很重要的地位。

C．不少保健品都有不同程度的副作用。

D．“奥米加一3”脂肪酸只有和主要存在于鱼体内的某些物质化合后才能产生保健疗效。

From the first use of the rocket to carry satellites into space to the setting up of space stations, human beings have been putting great effort into space research. And so far, we have achieved many successes. But there are still numerous tasks in front of us and we should not stop trying to progress.

The international space station (ISS) is an important step we should take in space exploration. It is not only helpful but also essential. It provides a proper space environment for many experiments that we have wanted to do for a long time. It is also a base for the observations of the earth and the universe. It could also be an important base for later travel to the moon and Mars. In a word, if we want to explore space more, the first thing we should do is to set up a space station.

As the space station costs a lot of money, it is hard for one country alone to establish one. The USA seems to be the only country that has the ability to build a space station alone，and it has tried to do so, but not very successful. So it aggregated many other countries to work on it together. Though it is still extremely expensive, it is much cheaper than doing it alone. It is really a job that needs everyone’s effort and will benefit everyone.

Led by the U.S. and Russia, the ISS is a joint project between six space agencies involving 16 countries. Called the greatest achievement in human cooperation, the ISS has come to the end of a ten-year’s hard work in construction. China has applied for participation in (taking part in) the project many times. Unfortunately all the applications were rejected, which drove China onto the path of independent development. As the Long March Ⅱ-F/T1 carrier rocket blasted off (leave the ground) and successfully carried the Tiangong-1 into space on September 29, 2011, China takes a big step toward its Space Station Era.

Some West media suggested that the successful launch of Tiangong-1 would disturb the balance of global space power, raising concerns (关注) about “China threat”. China’s space project is not designed for military (军事的) purpose but for developing space technology to explore space resources and make use of them for mankind’s well-being.
