There are quite a few advantages of wearing school uniforms. The idea may seem disagreeable at first, but considering all the positive effects coming from wearing uniforms you would be more likely to enjoy them.
Teachers love school uniforms because it helps provide an orderly learning environment. Having students dressed in uniforms may teach them how to present themselves in a neat and professional manner. It gives students the opportunity to learn how to dress like young ladies and gentleman. And they can focus their attention on academics rather than style.
Purchasing (购买) school uniforms is easy and needs less hesitation and consideration. No matter what the school’s policy is, there are only specific essential (基本的) pieces to the wardrobe (服装) that are necessary, so it won’t break the bank. A few wardrobe items can last a long time. Parents could also enjoy an easy morning, as it will take less time to choose a set of clothes for the school day.
Students wearing uniforms will feel less pressure about what to wear or not to wear when their classmates are dressed similarly. Getting dressed before school becomes less of a chore(琐事) when students are limited in their choices, so there shouldn’t be any trouble about choosing an outfit for the day and getting ready quickly. Some students may not like the lack of individuality(个性) with a uniform, but some school dress code policies may offer them the opportunities to show their unique styles.
Uniforms today are also becoming trendier and can be seen in many areas of pop culture. Celebrities(名人)and fashion designers are using uniforms as inspiration for new looks which also appeal to students.

Fish species are expected to shrink in size by up to 24% because of global warming, say scientists.
The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected.
The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish"s body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size.
The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth"s poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future."
Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans.
When compared with actual observations of fish sizes, the model seems to underestimate what"s actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted.
Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously affect the ability of fish to reproduce. "Smaller fish produce fewer and smaller eggs which could affect the reproductive potential of fish stocks," he said.
小题1:What"s the main idea of the passage?| A．Global warming makes fish smaller. | | B．Global warming makes fish decrease in numbers. | | C．Global warming affects the fish distribution. | | D．Global warming affects the ability of fish to reproduce. |
小题2:What is the key factor making the fish smaller now?| A．The rising body temperatures. | | B．The lower level of oxygen in the water. | | C．The increasing metabolic rate. | | D．The normal body activities. |
小题3:We can infer that as ocean temperatures increase .| A．more big fish will be born in the sea | | B．fish tend to swim towards the shore | | C．fish tend to move towards the warm areas | | D．fish tend to move towards the colder areas |
小题4:What does the underlined word "underestimate" mean?| A．make an exact prediction of | B．make too low an estimate of | | C．make too high an estimate of | D．make a careful study of |

Attempts to understand the relationship between social behavior and health have their origin in history. Dubos (1969) suggested that primitive（原始的）humans were closer to the animals because they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain things and alleviating（减轻）symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes and cures of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual (礼仪) to drive harmful spirits away from a diseased body.
One of the earliest attempts in the Western world to formulate principles of health care based upon rational thought and rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B.C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings attributed to him have provided a number of principles underlying modern medical practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics (道德). Among other things, it requires a physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor-patient relationship.
Hippocrates also argued that medical knowledge should be derived（源自于）from an understanding of the natural sciences and the logic of cause and effect relationships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human-being is influenced by the totality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.
小题1:The topic of the first paragraph is summarized in ________.| A．the first sentence of the paragraph | | B．the second sentence of the paragraph | | C．the third sentence of the paragraph | | D．the last sentence of the paragraph |
小题2:Why did primitive humans rely on magic in their beliefs about the causes and cures of diseases?| A．Because magic was an inseparable part of their life. | | B．Because they had little knowledge about the functioning of the body. | | C．Because the diseases were caused by the evil spirits. | | D．Because magic must be used in going through the rituals to drive out the evil spirits. |
小题3:Considering Hippocrates’ background, we can see from the second paragraph that ________.| A．he was the forefather of modern medicine | | B．experts are sure that the books bearing his name were not written by him | | C．he had a rational mind aided by supernatural instincts | | D．experts do not know much about him except when and where he lived |
小题4:All of the following are included in the Hippocratic Oath EXCEPT ________.| A．helping patients | | B．keeping oneself from harming patients | | C．keeping secret all matters to maintain a good relationship with the patients | | D．obeying rules for modern medicine practice |
小题5:Which of the following best expressed the main idea of the last paragraph?| A．Doctor’s concerns remain unchanged. | | B．Medicine comes from nature. | | C．Environment affects health. | | D．Climate determines lifestyle. |

A study suggests that although most students at UK universities are happy with their courses, dissatisfaction has grown as fees rise．The study highlights a big variation in teaching time, and lists different ideas about the value of getting university degrees．
Katharine Collins, a second-year college student
The course has been very interesting, but I was expecting a little more one-to-one time with my teacher．
We do about four assignments （作业） each term, each of which is about 3,000 words．However, sometimes they are not that helpful．We hope to be given the right to write feedback （反馈） after every assignment, but we had no feedback at all throughout the first year．We are given grades about three weeks after we hand the assignments in．There is no feedback on where we have gone wrong or how we might improve．
Lee Millington, a creative-writing student
I choose the courses because of its reputation．There is a lack of one-to-one teaching．I would like personalized feedback from an expert in my field of writing．Some of the lectures have been quite helpful but they try to use too many different styles of writing．For example, if you want to be a poet, you might find that the lectures focus too much on novels．
I think there is too much attention paid to sharing our work in workshops and giving each other feedback．I think there should be more time given to actual teaching, rather than to feedback from people who are at a similar level to me．
Reporters from Hounsdown Secondary School, Ella, 16
When I work independently, I feel I have more freedom to develop my ideas and come up with more original viewpoints．The price of university will still be worth it to get the qualifications （资格证书）necessary for better jobs．
Tyier, 16
Although the cost of university is very high now, I think university is required for gaining a good and well-paid job．

Cloud seeding is a method of artificially causing clouds to produce precipitation （降水） in the form of rain or snow．Cloud seeding has also been used in attempts to modify the severity of hail storms and hurricanes．The effectiveness of cloud seeding remains controversial （有争议的）．but it continues to be used in some regions to try to increase rainfall for agriculture and to build snow packs for water supplies and power production．
Cloud seeding was developed by American scientists Irving Langmuir and Vincent Joseph Schaefer during and after World War II．Their work began as an effort to learn more about the buildup of ice on airplane wings, and eventually led them to attempt to create rainfall by releasing several pounds of crushed frozen carbon dioxide into a cloud from an airplane．In this form, the carbon dioxide is called dry ice．On November 13, 1946, the technique appeared to produce snow directly under the cloud; the snow then turned to rain as it fell to the ground．
For their experiment, Langmuir and Schaefer selected a supercooled cloud, one in which the water droplets remain liquid in subfreezing temperatures．Their theory was that small grains of dry ice falling through the cloud would cause tiny droplets of water vapor in the cloud to freeze into crystals that attracted more water vapor．Their theory proved to be correct and eventually the crystals became heavy enough to fall from the cloud as snow．As the snow reached the warmer temperatures closer to the ground, it melted and became rain．
Another scientist, Bernard Vonnegut, produced a method of cloud seeding using silver iodide （碘化银）．He used particles of silver iodide because its crystal structure resembled that of ice in clouds．Silver
iodide also had practical advantages over frozen carbon dioxide It could be stored at room temperature
and did not require an airplane as a delivery mechanism．Instead, silver iodide crystals could be fired by
cannons （大炮） high into the air, where wind carried them into the clouds．
小题1:According to the text, Langmuir and Schaefer had intended to deal with__
A．how to freeze carbon dioxide
B．how to remove ice on plane wings
C．how to make weather forecast for the war
D how to hide planes in clouds at war
小题2:What is the CORRECT order of the course for cloud seeding with dry ice?
a．snow becoming rain in wanner temperatures b．crystals attracting more water vapor
c．crystals falling in the form of snow d．crystals becoming very heavy
e．freezing tiny droplets of water vapor into crystals
f．putting small grains of dry ice in the cloud| A．a-c-f-d-b-e | B．b-f-e-a-c-d | | C．f-e-b-d-c-a | D．e-a-d-c-b-f |
小题3:Bernard chose silver iodide as a method of cloud seeding because___．| A．it is much cheaper than dry ice | B．it can be stored at any rooms | | C．it can be sent into clouds by wind | D．it is similar |
小题4:The best title for the passage may be "____"．| A．Cloud Seeding | | B．Artificial Raining | | C．Weather Changing | | D．Cloud Gathering |
小题5:How many methods of cloud seeding are mentioned in the passage? |
Researchers conducting a study of hospital stays for over two hundred and eighty six thousand older folks found something interesting in their data.
The number of hospitalizations for heart disease and stroke went down significantly among a certain group of people at a certain time of year. What folks, and what time of year, you ask? Flu season and the lucky people were the ones who got flu shots(流感疫苗).
It’s generally recommended that people over fifty get their flu shots every year. Influenza(流行性感冒) is no small thing. it’s responsible for around thirty six thousand deaths a year in the U. S. alone. Getting the shots also cuts down on the chances of getting pneumonia(肺炎), which is especially dangerous in seniors.
But what wasn’t known was that there seems to be an added benefit to getting a flu shots in terms of warding off heart problems. The data,in fact, are quite strong in suggesting this is the case.
In this study, flu shots cut clown the number of hospitalizations for heart disease by nineteen percent. Stroke went down sixteen percent one season and a whopping twenty-three percent a second season.These are big results.
So what"s the connection between getting a flu shot and having a stronger heart? It isn’t yet known.
Researchers speculate that the flu virus itself may do damage to blood vessels(血管), possibly making clots(血块)more likely. Blood clots in the heart can cause heart attacks, and blood clots in the brain can cause strokes.
Whatever the specific details are, there"s one more good reason to follow your doctor’ s advice and get that annual flu shot.
小题1:According to the study, the number of hospitalizations for heart disease and stroke went down significanntly among the ones who _____.| A．got flu shots after they were ill | | B．got flu shots before they were ill | | C．got flu shots at the flu season | | D．got flu shots whenever convenient |
小题2:The benefits of getting flu shots can be listed except that_____.| A．it can cut down on the chances of gettingpneumonia | | B．it can cut down the number of hospitalizations for heart disease | | C．it can kill the flu virus | | D．if can make blood clots |
小题3:The underlined phrase "warding off" probably means_______.| A．keeping away | B．dealing with | C．setting off | D． picking up |
小题4:According to the passage, we"d better ______.| A．work out to fight against influenza | B．get flu shot every year | | C．follow our doctor"s all advice | D．protect our blood vessels |
