What time of day can you think most quickly? Are you a morning person? Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.
Many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you wake up can help your body’s temperature rise quickly.
But everyone’s body clock is different and some are special. Morning people will get up early and
work better early in the day. Evening people will work later but work better towards the end of the day. Research shows that we’re better at some activities at certain times of the day. Physical performance is at its best between 3 pm and 6 pm, so it’s better to exercise later in the day.
Between noon and 4 pm, people begin to pay less attention. This is because we think less quickly
after a big meal. Research also shows we become sleepy around 2 pm. This is why people in Spain take a short sleep in early afternoon. Finally, it is best to eat when we’re active. This allows our body
to burn calories better and stops our blood sugar levels from getting too high.__________ can tell us what time of day we can perform best at.

In the US and Britain, the slogan around colleges was “Save water. Shower with a friend.” Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit(IC) card reader at each tap shows the time. No mone
y, no water. The benefits of the new system can be seen with the old system, which charged 1 yuan for each person regardless of time in the shower. The university used about 320 tones of water daily under the old system, but only 160 tons now.
Many students use the new system but opinions on it are divided. Some student
s say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they’re still covered in soap. They have to ask the bathhouse worker to help them buy extra time.
“It’s a flaw in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students’ suggestions that they be allowed to pay after they’ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.
Without the time limits, most students tended to shower for 30 to an hour in the bathhouse. Some even used the hot water to wash their clothes. “In my experience, 10-20 m
inutes is enough,” said Dai Zhihua, a third-year student who usually takes 8 minutes. A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 yuan per minute. One male student responded by setting a record with a two-minute shower. According to the passage, which of the following is NOT true?
| A．Having finished bathing, the student has to pay for it. |
| B．The clock times all through while the student is bathing except when the bather paused for soap. |
| C．If money runs out, there will be no water. |
| D．Students pay for the amount of time they want in the shower. |
The underlined word “flaw” (Paragraph3) most probably means______.
| A．perfection | B．advantage | C．pity | D．fault |
Since the new system has performed, ______ of water can be saved.
| A．a quarter | B．one third | C．one half | D．two thirds |
It can be inferred from the passag
e that______.
| A．the new operation can solve the water crisis. |
| B．The new operation can raise students’ environmental awareness. |
| C．a similar operation has been set in other universities. |
D．The univ ersity has saved a lot of water by using the new system. |
China news, Beijing, July 29 --- Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not
sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate(控制) the real estate market by raising tax on property industry. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered. Wha
t is the average housing price per square meter in China?
| A．8000 yuan. | B．10000 yuan. | C．7000 yuan. | D．Not mentioned. |
Which of the following does NOT support the idea that the average housing price in China is even higher than in the United States?
| A．Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. |
| B．American people’s average income is several dozen times higher than that of Chinese people. |
| C．The population who need houses in China is larger than in the United States. |
| D．The houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. |
How many measures are mentioned in the last paragraph in order to reduce the high housing prices?
A．One. |
B．Two. | C．Three. | D．Four. |
What is the main idea of this passage?
| A．The housing price in China is so high that the government should do something useful to prevent it. |

| D．Chinese government issued a set of policies that aimed to benefit the public. |

The word “day” has two meanings. When we talk about the number of days in a year, we are using “day” to mean 24 hours. But when we talk about day and night, we are using “day” to mean the time between sunrise and sunset. Since the earth looks like a ball, the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning(旋转) of the earth. At the equator(赤道) day and night are sometimes the same length. They are each twelve hours long. The sun rises at 6 in the morning and sets at 6 in the evening. For six months the North Pole is tilted(倾斜) toward the sun. In those months the Northern Hemisphere(半球) gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than night. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.When the Western Hemisphere is having day, the Eastern Hemisphere is having ______.
