【题目】China’s government has been trying all measures to reduce pollution in the past few years. Now people can enjoy a fresh environment everywhere. The following two graphs are adopted from the column of “City Information” on the webpage of Beijing Review.
Graph 1: Olympic Cities Air Quality Report
City | Date | API | Major Pollutant | Air Quality Degree | Quality Condition |
Beijing | Sep. 8 | 37 | N/A | Ⅰ | Very good |
Qinhuangdao | Sep. 8 | 52 | PM10 | Ⅱ | Good |
Qingdao | Sep. 8 | 68 | PM10 | Ⅱ | Good |
Shanghai | Sep. 8 | 67 | PM10 | Ⅱ | Good |
Shenyang | Sep. 8 | 88 | PM10 | Ⅱ | Good |
Tianjin | Sep. 8 | 54 | PM10 | Ⅱ | Good |
Graph 2: Chinese National Standard
API Values | Levels of health concern | Colors |
When the API is in this range: | ...air quality conditions are: | ...as symbolized by this color: |
0 to 50 | Very good | Blue |
51 to 100 | Good | Green |
101 to 150 | Slight pollution | Yellow |
151 to 200 | Orange | |
201 to 250 | Medium pollution | Red |
251 to 300 | High pollution | Purple |
301 to 500 | Hazardous | Brown |
Notes:
**API stands for Air Pollution Index(指数).
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.
**Sulfur dioxide(SO2) acts as an acid.Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.
【1】According to Graph 1, which of the following cities has the worst air pollution?
A. Qinhuangdao. B. Tianjin.
C. Qingdao D. Shenyang.
【2】If your city is symbolized by either red or purple, the pollution in your city is .
A. Moderate or high. B. Moderate or slight.
C. Medium or high. D. Medium or slight.
【3】Which of the following statements is TURE?
A. With API value below 150 the air is free from being polluted.
B. The colors from purple to Yellow indicate the air quality is becoming much worse.
C. When there are floating solid particles and dust in the air, it is dangerous pollution.
D. On September /span>8th the color-symbol of Beijing City’s air quality is ‘Blue’.
【4】When more citizens are beginning to have labored breathing soon after they are in the open air, it suggests that .
A. there is a large amount of sulfur dioxide in the air
B. it is so cold that they may have caught a cold
C. they are starting to cough or have a fever
D. they must be infected with permanent lung disease
【题目】One day, Amy is digging in the ground for a potato when along comes Tom. Seeing that there is no one in sight, Tom starts to scream. Tom’s angry mother rushes over and drives Amy away. Once his mum has gone, Tom helps himself to Amy’s potato.
We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Amy and Tom are not humans. They’re African baboons(狒狒).【1】
Tom’s scream and his mother’s attack on Amy could have been a matter of chance, but Tom was later seen playing the same tricks on others.【2】
Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated.【3】An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”
Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe.【4】But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.
It seems that trickery does play an important part in ape societies.【5】Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.
A.An amusing example of this comes from a psychologist working in Tanzania. |
B.And playing tricks is as much a part of monkey behavior as it is of human behavior. |
C.So the psychologists asked his colleagues if they had noticed this kind of trickery. |
D.Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why. |
E. This use of a third individual to achieve a goal is only one of the many tricks commonly
used by baboons.
F. The ability of animals to cheat may be a better measure of their intelligence than their use
of tools.
G. In most cases the animal probably doesn’t know it is cheating.
