Have you ever heard the saying: All work and no play make Jack a dull boy? What this means is that if you study all the times you will become a boring person. You must go out and have a fun with your friends, otherwise you will lose him. No one wants to be friends with someone only talked about work and study.
Perhaps you have a confident problem. Please try to remember that you do is just for yourself rather than no one else, but do not compete with your classmates. No one can be happier in studying seven days and seven nights in a week.

The Dark Age of Greece
【小题】Among early civilizations, we call the low points "dark ages", because civilizations often dropped to such a low level that it is hard to get an accurate picture of their history during these periods. During a dark age, a civilization may not have produced monuments, statue, or other objects which we use to learn about early civilizations.
One' of the most important dark ages was the dark age of Greece,which lasted from about 1100 BC to 900 BC. Prior to-that-time,Greece had a highly advanced society called the Mycenaean civilization. The Mycenaeans were a trading civilization1.In fact, the Mycenaean civilization was so important that when it collapsed in the 12th centuryBC,most other civilizations in the region collapsed as well.The next 200 years are like a blank page to historians and we know very little about this period.2.The collapse of the Mycenaeans brought an end to writing in the area, and thus an end to the written records historians rely on.
The little that we know about this period has been learned from archaeology. It seems that civilization became much less advanced. The pottery from this period is much simpler and less artistic. This suggests that there was lack of wealthy people to buy higher quality products. 3. This would suggest a large decrease in population, possibly due to a widespread lack of food and consequent starvation.
Sometime around 800 BC, the Greeks began to emerge from this dark age, most probably due to the influence of other civilizations. They had lost their early writing system, but began to use the writing system of the Phoenicians at this time.4.Over the next 300 years, their civilization continued to rise, and their dark age was forgotten.
A.Many civilizations undergo a series of high points and low points during their history.
B.Many early civilizations underwent dark ages, but Greece never recovered from its dark age.
C.They began constructing larger cities and trading with their neighbors again.
D.Another interesting point is that most of the large cities of earlier time periods appear to have been abandoned in favor of much smaller settlements.
E.Many pieces of evidence suggest that there was a huge increase in population during the dark age of Greece.
F.and they did much to spread their culture across the eastern Mediterranean.
G.One major reason for this is that writing basically stopped.
Our senses aren't just delivering a strict view of what’s going on in the world; they're affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who've just eaten.
Psychologists have known for decades that what's going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Rémi Radel of University of Nice Sophia-Antipolis, France, wanted to investigate how this happens.
Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-1evel thinking processes get involved. Radel recruited 42 students with a normal body mass index. On the day of his or her test, each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch first. So half the students were hungry when they did the experiment and the other half had just eaten.
For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen for about l/300th of a second each. They flashed at so small a size that the students could only consciously perceive. A quarter of the words were food-related. After each word, each person was asked how bright the word was and asked to choose which of two words they’d seen-a food-related word like cake or a neutral word like boat. Each word appeared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food- related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception, not in thinking processes, Radel says. "This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment, I know that our brain can really be at the disposal of our motives and needs. "Radel says.
1.Why was there a delay on the day of the experiment?
A. Because hungry people needed time to fill their stomach.
B. Because Radel wanted to create two groups of testers, hungry and non-hungry.
C. Because noon was not the right time for any experiment.
D. Because Radel needed time to select participants in terms of body mass index.
2.What does the writer want to tell us?
A. Human’s senses aren’t just delivering a strict view of what’s going on in the world.
B. What’s perceived by our senses affects our way of thinking.
C. Human brains can really be at the disposal of our motives and needs.
D. Thinking processes guarantee the normal functions of our senses.
3.What can we infer from the passage?
A. 42 participants are too small a number for a serious investigation.
B. An experiment with hungry and non-hungry participants is not reliable.
C. Our thinking processes are independent of our senses.
D. Humans can perceive what they need without involving high-level thinking processes
Taste is such a subjective matter that we don’t usually conduct preference tests for food. The most you can say about anyone’s preference is that it’s one person’s opinion. But because the two big cola companies—Coca-Cola and Pepsi Cola are marketed so aggressively, we’ve wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting.
We invited staff volunteers who had a strong liking for either Coca-Cola Classic (传统型) or Pepsi, Diet (低糖的) Coke, or Diet Pepsi. These were people who thought they’d have no trouble telling their brand from the other brand.
We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants’ choices with what mere guess-work could have accomplished.
Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse----only 7 of 27 identified all four samples correctly.
While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste burnout, was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price.
