Many of us live with a roommate at some stage． Sometimes， there can be problems． Who hasn't had an argument about whose turn it is to take out the rubbish or who should be the one to clear up after dinner？1.
You know that there's always someone else around， which can help you feel safer． There is always someone to talk to， so you never feel lonely． Besides these obvious benefits， there are some you may not notice．2.
To examine the effect of living alone， Australian university researchers did much research and found that people living alone tended to eat less fresh food， which can have a significant negative effect on long-term health． However， those living with others generally benefited from a more varied diet compared to those living alone．
3.The researchers believe the social and cultural roles played by cooking， food preparation and eating may be important considerations． For example， those living with friends have someone else to go shopping with， and thus are likely to buy high-quality fresh food regularly．
4.If people living alone find they do not have the knowledge required to prepare a particular dish or cook a certain food， they may fall back on ready-made， less healthy food． However， if they live with at least one other person， they may be able to ask for help．
In addition， people living alone can eat whatever they want at any time of the day or night． However， it's helpful to have someone around who questions your decision to eat frozen pizza at 3am．5.
So， if you now live alone and find yourself fighting a losing battle against poor eating habits， why not consider sharing a home with someone else？ You could encourage one another on to greater health and well-being．
A． Cooking skills may be another factor．
B． In other words， roommates can draw your attention to unhealthy routines．
C． Living with a roommate could be a good thing because a roommate can share your expenses and contribute to your home's maintenance．
D． For example， we're actually more likely to eat healthier food when living with others．
E． What could explain these findings？
F． It's hard to find someone who doesn't grate on your nerves， has a similar cleanliness level as you and goes to bed at the same time．
G． However， living with another person also comes with many benefits．

Many jobs must be done with two people. One person takes the lead. The other helps. So it is with the human body. Much of our body depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance.
Some of the most important helpers in the job of good health are the substances we call vitamins. The word “vitamin” dates back to Polish scientist Casimir Funk in 1912. He was studying a substance in rice. Funk believed the substance belonged to a group of chemicals known as amines (胺类). He added the Latin word “vita”, meaning life. So he called the substance a “vitamine”—an amine necessary for life.
Other studies found that not all vitamins were amines. So the name was shortened to vitamin. But Funk was correct in recognizing their importance.
Scientists have discovered 14 kinds of vitamins. They say vitamins help to carry out chemicals changes within cells. If we do not get enough of the vitamins, we are at risk of developing a number of diseases. This brings us back to James Lind of Scotland. In the 1740s, Lind was a doctor for the British Navy. He was investigating a problem that had existed in the Navy for many years.
The problem was the disease scurvy(坏血病). The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months.
Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker.
However, which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.
1.Why was the name “vitamine” shortened to “vitamin”?
A. Because Funk was totally wrong.
B.Because few vitamins were amines.
C. Because there were new findings.
D. Because the latter was easy to remember.
2.The underlined word “This” in the fourth paragraph probably refers to that _______.
A. people tend to develop many diseases
B. lack of the vitamins causes disease
C. vitamins help chemical changes within cells
D. it is common for people to get no enough vitamins
3.Doctor Lind proved eating fruits can prevent scurvy by means of _______.
A. comparing B. analyzing C. surveying D. questioning
4.What is the main topic of the passage?
A. Food to keep us healthy.
B. The benefits of vitamins.
C. Research into scurvy.
D. Facts about vitamins.

Anyone with a passing interest in their health will be able to rattle__off a few of the major vitamins, and possibly take an educated guess at what they do. Vitamin C, found in oranges and other fruit and vegetables, is important for wound repair. And the much－talked－about ‘sunshine’ Vitamin D, produced by the skin in response to UV light, is essential for strong bones.
But Vitamin P? It might well have you scratching your head. And that's not surprising: the term was first coined in the 1930s to describe a small group of compounds that provide pigment(天然色素) to plants, and were believed to have health benefits. Fast－forward almost a century and these compounds are now better known as flavonoids.
Today, scientists have identified between 4，000 and 6，000 different kinds and we now know they are responsible for many of the flavors and smells of fruit and vegetables and also that they protect them from invaders such as pests and bacteria.
They are equally important nutrients for the body, helping maintain bones and teeth, and for the production of the protein collagen(胶原), which provides structure to blood vessels, muscles and skin.
They are also said to help the body deal with some of the key drivers of illness, including oxidation(氧化), a natural process by which the body's cells age and can become damaged and defective(有缺陷的). That means they could help to protect against chronic diseases including cancer and heart disease.
1.Which of the following best explains “rattle off” underlined in Paragraph 1?
A.Quickly say. B.Quickly pass.
C.Quickly find. D.Quickly take.
2.What do we know about Vitamin P?
A.We would scratch our head if we took it.
B.It was made into a coin in the 1930s.
C.People didn't think it beneficial in the past.
D.It refers to the compounds also called flavonoids.
3.How many functions of Vitamin P for humans are mentioned?
A.Four. B.Three.
C.Two. D.One.
4.How does Vitamin P help slow the aging process?
A.By dealing with oxidation.
B.By maintaining bones.
C.By strengthening muscle.
D.By protecting against chronic diseases.

高三英语单项填空中等难度题查看答案及解析
Nowadays many people are concerned about the problem of what to do with electronic waste such as old televisions, computers, radios, cellular telephones and other electronic equipment.
Electronic trash, or e-waste, is piling up faster than ever in American homes and businesses. People do not know what to do with old televisions or computers so they throw them in the trash.
National Solid Waste Management Association (NSWMA) state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected.
The US Environmental Protection Agency (EPA) estimates more than 400 million consumer electronic items are dumped each year, and there is a push by more states to ban the waste from landfills (垃圾填埋场) and create recycling programs. They can be torn apart and sorted for useable parts. Mike Fannon who runs the plant in Baltimore says, “There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill, and in certain components there are some materials that should not really be in the landfill.”
Fannon says nearly 20 percent of electronic waste is recycled nationwide. Thirteen years ago, it was only about 6 percent. Recycling rates continue to rise as more communities have banned electronics from landfills in order to keep e-waste poisons like lead (铅) and mercury (汞) out of garbage dumps.
This year several states like Vermont imposed a ban on electronic waste in landfills. More than 25 other states have also adopted bans on e-waste in landfills. Chaz Miller says more can be done to boost electronic waste recycling.
“We can do much better,” noted Miller. “I think clearly our goal should be to do as well as we do recycling newspapers.”
1.Which of the following does NOT belong to e-waste?
A. Old televisions. B. Old computers.
C. Old cell phones. D. Old newspapers.
2.Why is e-waste banned from landfills in many states?
A. Because it can not be recycled.
B. Because the landfills are already full.
C. Because it might damage the environment.
D. Because it can be shipped to other countries.
3.According to Mike Fannon, what might be the best way of dealing with e-waste?
A. Recycling it. B. Selling it.
C. Burying it. D. Breaking it.
4.What can we learn from the passage?
A. Chaz Miller works for EPA.
B. Miller is optimistic about the future of e-waste.
C. At present, less than 10 percent of e-waste is recycled.
D. All states in the US have banned e-waste from landfills.
高三英语阅读理解困难题查看答案及解析
In recent years many countries have been faced with the problem of how to make their workers more productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead to greater productivity? There is something to suggest that while variety certainly makes the worker's life more enjoyable, it does not make him work harder. So variety is not important.
Other experts feel that giving the worker freedom to do his job in his own way is important and there is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice may be important, there is very little that can be done to achieve this.
Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are said to be experimenting with having many small production lines rather than a large one, so that each worker contributes more to the production of the cars on his line. It would seem then that the degree of worker contribution is important.
To what extent does more money lead to greater productivity? The workers themselves certainly think this is important, but perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if companies succeed in making workers' jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.
72. Which of the following things will not increase productivity?
A. Making jobs more varied.
B. Longer working hours.
C. Giving workers the freedom to do his jobs in their own way.
D. Increasing the workers' contribution to production.
73. The last sentence in this passage means that if companies manage to make workers' jobs more interesting, _________.
A. they will want more money
B. they will demand shorter working hours
C. more money and shorter working hours are important
D. more money and shorter working hours will not be so important to them
74. In this passage, the writer tells us _________.
A. how to make the workers more productive
B. possible factors leading to greater productivity
C. more money leads to greater productivity
D. how to make workers' jobs more interesting
75. The writer of this passage is probably a _____________.
A. teacher B. worker C. manager D. physics
