[单项选择]How exactly, does science work How do scientists go about doing science Ordinarily we think science proceeds in a straight-forward way. Ideally scientists make observations, formulate hypotheses (假设), and test those hypotheses by making further observations. When there is difference between what is observed and what is predicted by the hypothesis, the hypothesis is revised. Science proceeds in this way, which is a gradual method of finding the best fit between observation and prediction.
But this idealized version of how one does science is naive. Although science demands proof that observations made by one observer be observable by other observers using the same methods, it is by no means dear that, even when confronted with identical phenomena, different observers will report identical observations. And it is most certain that, even if the same observations are made, the conclusions as to the meaning of the observations frequently differ.
The fact is that all of us, s
A. The research methods used by scientists.
B. Observation and human perception variation.
C. The relation between hypothesis and observation.
D. The human perceptual mechanism.

[单项选择]A pretty pot plant might make an unemotional work space feel more personal. But new research has revealed that office plants do so much more as they can help staff be more creative and productive, which could ultimately【C1】______promotion. At work,【C2】______houseplants have been proven to aid concentration, increase productivity and【C3】______staff well-being by 47 per cent, according to a study undertaken at this year"s Chelsea Flower Show. The results showed that【C4】______staff to make design decisions in a workspace【C5】______with office plants can increase creativity by 45 per cent and improve productivity by 38 per cent. The researchers believe their findings demonstrate that plants are not unnecessary【C6】______of business environments and add【C7】______to other studies, which indicate plants increase psychological comfort and business【C8】______.

It was time to go a step【C9】______and see whether the principle can also【C10】______creativity and indeed whether the very act of designing the workspace can be used effectively. The results indicate that plants, in a well-designed and personalized office environment can increase business effectiveness【C11】______improved staff productivity and creativity. This gives company managers a real【C12】______to share control of office space with their staff and create meaningful, less【C13】______and more grown up space." Plants have previously been proven to have【C14】______effects in hospitals, where patients with pot plants close by said they experienced less pain, anxiety and tiredness,【C15】______houses with plant-filled rooms【C16】______between 50 and 60 per cent fewer bacteria than other rooms【C17】______plants. Monique Kemperman from The Joy of Plants, said: "Scientific studies have demonstrated that we can see a【C18】______improvement in air quality alone, just by【C19】______a few common houseplants around a room."
