If you’re training for a marathon , a proper plan for water intake (摄入) is important. Of course, there’s the risk of dehydration (脱水). But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium (钠) in the blood . The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research.
Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight.
One technique for deciding how much water you need is to get the exact numbers. Runners have to weight themselves before and after a run to determine how much water they’ve lost. If their weight drops by more than 2 percent, they have not drunk enough water.
Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can’t get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration , the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water .

Thomas Hardy was an English novelist and poet. A Victorian realist, in the tradition of George Eliot, he was also influenced both in his novels and poetry by Romanticism, especially by William Wordsworth. Charles Dickens is another important influence on Thomas Hardy. Like Dickens, he was also highly critical of much in Victorian society, though Hardy focused more on a declining rural society.
While Hardy wrote poetry throughout his life, and regarded himself primarily as a poet, his first collection was not published until 1898. Initially therefore he gained fame as the author of such novels as Far from the Madding Crowd (1874), The Mayor of Casterbridge (1886), Tess of the D'Urbervilles (1891), and Jude the Obscure (1895). However, since the 1950s Hardy has been recognized as a major poet, and had asignificantinfluence on The Movement poets of the 1950s and 1960s, including Phillip Larkin.
The majority of his fictional works,initiallypublished as serials in magazines, were set in the semi-fictional region of Wessex and explored tragic characters struggling against their passions and social circumstances.

Dogs can be trained to identify the smell of lung cancer long before symptoms develop.
A new study is the first to show that sniffer dogs can be relied upon to find the unique smell of the disease of in 7 out of 10 sniffers. Researchers from a hospital in Germany believe dogs could become even better at picking out cancer cases with more training, but the final goal is to identify the cancer-specific chemical compounds the dogs can smell, and develop a device that could be used to help diagnose lung-cancer victims at an earlier stage.
Lung cancer is Britain’s deadliest cancer, with over 39.000 cases diagnosed annually, of which only 25 percent will survive for a year, since the disease is mostly found at an advanced stage, when it is very difficult to treat. Early detection is often by chance, although scientists have been working on using samples of exhaled(呼出的) breath from patients for future screening. They attempt to use the samples to locate volatile organic compounds(VOCs) in the breath that are linked to the presence of cancer, but no reliable methods have been found so far that are lung-specific.
The researchers combined this approach with recent findings about the abilities of some dogs to alert their owners to undiagnosed cancer, probably through smell. This latest study used family dogs, which were given special training over an 11-week period to identify a VOC in the breath of patient.
The researches worked with 220 volunteers, including patients with lung cancer at early and advanced stage, patients with chronic pulmonary disease(慢性肺炎), and healthy volunteers. The dogs took part in a number of tests to see if they could reliably distinguish compounds in the breath of lung-cancer patients-even if they smoked. The dogs were asked to sniff glass tubes containing cotton impregnated(浸染) with samples of breath from those taking part and had to lie down if they detected a VOC from a lung cancer patient.
The dogs successfully identified 71 samples with lung cancer out of a possible 100. They also correctly detected 372 samples that did not have lung cancer out of a posible 400.What can we conclude from the research according to the passage?
| A．The volunteers included patients with various cancer successfully |
| B．It used police dogs specially trained over a period. |
| C．It aimed to see if dogs could sniff cancer-specific compounds. |
| D．The dogs identified 372 samples with lung cancer successfully. |
We can infer from the passage that a VOC is probably a kind of _____.
| A．liquid | B．drug | C．equipment | D．chemical |
Which of the following is Not true according to the passage?
| A．The research involved about a hundred dogs in all. |
| B．Dogs can usually detect the lung cancer patients well. |
| C．There are about 39,000 lung-cancer patients in Britain every year. |
| D．Lung cancer is Britain’s biggest cancer killer. |
What can be the best title of the passage?
| A．A New Way to Treat Cancer |
| B．A New Way to Detect Disease |
| C．Dogs Can Sniff out Cancer |

A person, like a commodity, needs packaging. But going too far is absolutely undesirable. A little exaggeration, however, does no harm when it shows the person's unique qualities to their advantage. To display personal charm in a casual and natural way, it is important for one to have a clear knowledge of oneself. A master packager knows how to combine art and nature without any traces of modification, so that the person so packaged is no commodity but a human being, lively and lovely.
A young person, especially a female, shining with beauty and full of life, has all the favor granted by God. Any attempt to make up would be self-defeating. Youth, however, comes and goes in a moment of doze. Packaging for the middle-aged is primarily to repair the furrows(磨损) ploughed by time. If you still enjoy life's enthusiasm enough to keep self-confidence and pursue pioneering work, you are unique in your natural qualities, and your charm and grace will remain. Elderly people are beautiful if their river of life has been, through plains, mountains and jungles, running its course as it should. You have really lived your life which now arrives at a complacent stage of serenity indifferent to fame or wealth. There is no need to resort to hair-dyeing-the snow-capped mountain is itself a beautiful scene of fairyland. Let your looks change from young to old synchronizing(同步) with the natural aging process so as to keep in harmony with nature, for harmony itself is beauty, while the other way round will only end in unpleasantness. To be in the elder's company is like reading a thick book of elegant edition that fascinates one so much as to be willing to part with.
As long as one finds where one stands, one knows how to package oneself, just as a commodity establishes its brand by the right packaging.In writer’s opinion, to show one’s personal charm casually and naturally, one ought to _____.

Sit Up Straight: Tips for Improving Your Terrible Posture
The more time we spend sitting in front of our computers, the worse our posture gets. Modern technology is turning us into literally twisted creatures.
In addition to being detrimental to how your body functions, bad posture isn’t cute. It causes you to jut(突出) your hips forward, slump your shoulders, and even breathe inefficiently, according to Pat Davidson, a trainer with a PhD in Exercise Physiology who is the Director of Training Methodology and Continuing Education Coordinator at Peak Performance in NYC.
Davidson explained that bad posture compromises your diaphragm(隔离), the big muscle right below the ribs that helps you take deep breaths. So instead, you start using other muscles, like your shoulders, to help you breathe. It turns out that people with lousy posture don’t walk correctly, and they count on their lower back muscles to help propel themselves forward.
Here are a few quick fixes recommended for correcting your slump:
• If you sit at a desk all day, don’t perch on the edge of your chair at work trying to sit up straight. The best thing you can do is keep your hips against the back of the chair and use it for support—that’s what it’s there for.
• Get up frequently and walk around.
• If you carry a heavy shoulder bag, make sure to carry it on both your right and left shoulder, switching off as each gets tired. Even better: wear a cross-body bag so that the weight’s more evenly distributed.
• Work out your core muscles. You can try backwards jump-roping. If the rope hits you, you have the wrong posture. Hula hooping is also a good choice.
• Focus on the upper back and shoulder muscles. One of her favorite exercises is having clients stand up against a wall, with your hips touching the wall. Put a tennis ball between your shoulder blades and try to squeeze the ball. Boating is also excellent for improving posture, since it causes you to pull your shoulders up and back.According to the passage, a bad posture can_____.
a. stop us from taking deep breathes
b. functionally change our body
c. hurt our diaphragm
d. make our walking posture incorrect
| A．bcd | B．acd | C．abc | D．abcd |
What does the underlined word “detrimental” in the second paragraph probably mean?
| A．harmful | B．helpful |
| C．meaningless | D．vital |
Which of the following tips is true for a good sitting posture?
| A．Sitting on the edge of the chair. |
