[单项选择] 第三篇 How We Form First Impression
We all have first impression of someone we just met. But why Why do we form an opinion about someone without really knowing anything about him or her - aside perhaps from a few remarks or readily observable traits
The answer is related to how your brain allows you to be aware of the world. Your brain is so sensitive in picking up facial traits. Even very minor difference in how a person’s eyes, ears, nose, or mouth are placed in relation to each other makes you see him or her as different. In fact, your brain continuously processes incoming sensory information - the sights and sounds of your world. These incoming signals are compared against a host of “memories” stored in the brain areas called the cortex(皮质) system to determine what these new signals “mean”.
If you see someone you know and like at school, your brain says “familiar and safe”. If you see someone new, it says, “new and potentially threatening”. The
A. One’s physical appearance can influence our first impression.
B. Our first impression is influenced by the sensitivity of our brain.
C. Stereotypical impressions can be dead wrong.
D. We should adopt mature thinking when getting to know people.

How the First Stars in the Universe Came into Existence
Researchers believe that our universe began with the Big Bang about 13 billion years ago, and that soon after that event, matter began to form as small dust grains and gases. How the first stars formed from this dust and gas has been a burning question for years, but a state-of-the-art computer simulation now offers the most detailed picture yet of how these first stars in the universe came into existence.
The composition of the early universe was quite different from that of today, and the physics that governed the early universe were also somewhat simpler. Dr. Naoki Yoshida and colleagues in Japan and the U.S. incorporated these conditions of the early universe, sometimes referred to as the “cosmic dark ages,” to simulate the formation of an astronomical object that would eventually shine its light into this darkness.
The result is a detailed description of the formation of a protostar — the early stage of a
A. was governed by simpler physics √
B. got fewer stars shinning in it
C. started over 13 billion years ago
D. was composed in a way similar to that of today
[单项选择]We have to realise how old, how very old, we are. Nations are classified as "aged" when they have 7 per cent or more of their people aged 65 or above, and by about 1970 every one of the advanced countries had become like this. Of the really ancient societies, with over 13 per cent above 65, all are in Northwestern Europe. We know that we are getting even older, and that the nearer a society approximates to zero population growth, the older its population is likely to be-- at least, for any future that concerns us now.
To these now familiar facts a number of further facts may be added, some of them only recently recognised. There is the apparent paradox that the effective cause of the high proportion of the old is births rather than deaths. There is the economic principle that the dependency ratio-- the degree to which those who cannot earn depend for a living on those who can--is more advantageous in older societies like ours than in the younger societies of the developing world, be
A. old people are more dependent than babies.
B. children are more handicapped than the aged.
C. the inactive aged are more reliable than children.
D. infants are more of a handicap than the elderly.
