Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment (营养).The old saying “An apple a day keeps the doctor away ”is not as silly as some people think. The body needs fruit and vegetables because they contain vitamin C. Many people take extra vitamins in pill form, believing that these will make them healthy.
But a good diet is made up of nourishing food and this gives all the vitamins you need. The body doesn’t need or use extra vitamins, so why waste money on them?
In the modern western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening,

Instead, a few muscles could claim the title, depending on how strength is measured.
If the title goes to the muscle that can exert(产生) the most force, the victor would be the soleus(小腿肚肌), according to Gray"s Anatomy(解剖学). Without this muscle, we wouldn"t be able to stand, walk, run or shake our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over ourselves (although some of us tend to do that from time to time anyway).
But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from force — pressure takes into account the area over which a force is exerted. The muscle that takes the prize for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book "Clinical Oral Science" (Reed Educational and Professional Publishing, 1998).
In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench(咬紧) and chew because of the masseter muscle.
Others may argue the muscles used in childbirth are the most powerful.
When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity(伸缩性) and forcefulness gives us the ability to speak, eat and kiss – all things very desirable on a first date. However dexterous(灵巧的) it may be though, its power does not match that of muscles such as the soleus.
If slow and steady wins the race, the heart is certainly a contender for the title. When it contracts, the muscle pumps about 2 ounces (59 milliliters) of blood, and is constantly working over a lifetime. Beating about 40 million times a year, a person"s heart will beat approximately 2.5 billion times by the time of their 70th birthday.
小题1:According the passage, the underlined word “contender” in the last paragraph is closet in meaning to “ ”.
A.failure | B.partner | C.muscle | D.competitor |
A.What’s the strongest muscle in the human body? |
B.who is the strongest person in the world? |
C.What are the functions of different muscles? |
D.What are the standards of the strongest muscle? |
A.Without the soleus, we could still stand, walk, run or shake our bodies on the dance floor |
B.a few muscles could be the winners, according to different measures |
C.the muscles used in childbirth are the most powerful |
D.tongue is the strongest muscle for delivering the greatest amount of pressure |
A.Another possible strongest muscle. | B.the conclusion of the strongest muscle. |
C.The functions of different muscles. | D.the Guinness record of strongest muscle. |
Fox Point is operated by Palladia, a group that specializes in providing housing and services to needy people. Palladia received support from Enterprise Community Partners (ECP), which helps build affordable housing by providing support to housing developers.
ECP has created national standards for healthy, environmentally (环境方面) clever and affordable homes which are called, the Green Communities Standards. These standards include water keeping, energy saving and the use of environmentally friendly building materials. Meeting the standards increases housing construction costs by 2%, which is rapidly paid back by lower running costs. Even the positioning of a window to get most daylight can help save energy.
Michael. Bloomberg, New York"s mayor plans to create 165,000 affordable housing units for 500,000 New Yorkers. Almost 80% of New York City’s greenhouse-gas emissions come from buildings, and 40% of those are caused by housing. So he recently announced that the city’s Department of Housing and Preservation and Development (DHPD) , whose duty is to develop and keep the city’s supply of affordable housing, will require all its new projects to follow ECP’s green standards.
Similar measures have been taken by other cities such as Cleveland and Denver, but New York’s DHPD is the largest city developer of affordable housing in the country.
小题1:What is the purpose of describing the boiler room in the first paragraph?
A. To explain the measures the city takes to care for poor people. |
B. To suggest that affordable housing is possible in all areas. |
C. To show how the environment-friendly building works. |
D. To compare old and new boiler rooms. |
A. Lower running costs. |
B. Costing less in construction. |
C. Less air to be lost in hot days. |
D. Better prices for homeless people. |
A. New York City is seriously polluted |
B. people’s daily life causes many carbon emissions in New York City |
C. a great number of people in New York City don"t have houses to live in |
D. some other cities have developed more affordable housing than New York City |
A. To call on people to pay more attention to housing problems. |
B. To prove that some standards are needed for affordable housing. |
C. To ask society to help homeless people and low-income families. |
D. To introduce healthy, environmentally clever-and affordable housing. |
Some people with autism(孤独症) have __小题1:___ experts with their outstanding memories, mathematical skills or musical talent. Now scientists have found that the genes thought to cause autism may also confer(给予) mathematical, musical and other skills on people without the condition.
The finding has _小题2:___ from a study of autism among 378 Cambridge University students, which found the condition was up to seven times more common among mathematicians than students in other fields.
If __小题3:__, it could explain why autism - a ___小题4:___that makes it hard to communicate with, and relate to, others ─ continues to exist in all types of society. It suggests the genes responsible are usually ___小题5:__, causing the disease only if present in the wrong combinations. “Our understanding of autism is undergoing a ___小题6:__,” said Professor Simon Baron-Cohen, director of the autism research centre at Cambridge, who led the study.
“It seems clear that genes play a significant role in the causes of autism and that those genes are also ___小题7:__ to certain intellectual skills.”
Scientists have long been interested by the apparent ___小题8:__ between autism and intellectual gifts in specific fields. This has made autism a hot topic in popular culture, from films such as Rain Man, which starred Dustin Hoffman and Tom Cruise, to books such as The Curious Incident of the Dog in the Nighttime.
Temple Grandin, 61, was diagnosed(诊断) with autism as a child and is now professor of animal sciences at Colorado State University. She said: “People with autism have played a vital role in human evolution and culture. Scientists such as Isaac Newton and Albert Einstein show every __小题9:___ of having been autistic. The world owes a great deal to those who design and programme computers, many of whom show autistic traits.”
A surgical technique known as “keyhole surgery” has become more common in recent years. In general, the surgeon will make a couple of small incisions around the area where the operation is going to be performed. Tubes are pushed into the holes, and a tiny camera, which is called an endoscope, is put into the body. The camera is attached to a large monitor screen that is positioned so that the doctor can see it while he performs the operation. In addition to the camera, doctors also push their tiny surgical instruments through the tubes. The awkward part of keyhole surgery is that it is counterintuitive; that is to say, if a surgeon wants to move the tool to the left, he or she must push it to the right.
Other advancements in technology are also being used today in the OR (operation room). A new machine called the “da Vinci Surgical System” has been tested in hospitals in the U.S.. Unlike keyhole surgery, the da Vinci’s robot’s moving parts are designed to imitate the natural hand and wrist movement of a surgeon, thus providing better control and sensitivity. The system is controlled by a surgeon from a console(控制台). Sitting at a console a few feet from the patient, the surgeon can perform an operation by holding and moving highly sensitive pads that enable him or her to control the instruments. The area of the body on which the surgeon is working is enlarged on a screen, which is attached to the console. This gives surgeons a realistic three-dimensional view of the area — similar to what they would see during a traditional surgical procedure.
Although the da Vinci Surgical System is undergoing some trials for some procedures, it has been welcomed as revolutionary by many surgeons. Patients with serious illnesses must still undergo major surgery, but the smaller incisions and less invasive procedures typically mean that a shorter recovery time is needed. In some cases, the patient’s stay in the hospital has been cut in half when the da Vinci Surgical System was used. On the downside, some operations have taken up to fifty minutes longer because surgeons are inexperienced at using the new technology. As surgeons become more familiar with the machines, the time needed for surgical procedures is likely to decrease.

Because you feel full sooner, you eat less of your main course.
The soup regime(养生法)was tested by researchers at Pennsylvania State University, led by Dr Barbara Rolls.
They found that when people ate a first course of soup before lunch they reduced their total calorie intake by 20 per cent, compared with those who did not begin the meal with soup.
But those who favor creamy soups should be careful.Researchers stressed the soup must be low-calorie and based on stock(菜汤), not cream.
All of the soups tested in the study were made from identical ingredients - chicken stock , broccoli(硬花甘蓝), potato, cauliflower(菜花)and carrots.
They were mixed together to create four different textures and thickness from separate stock and vegetables through to pureed soup.
Scientists thought that thick soups with chunks of vegetables which required chewing might be more filling, but to their surprise they found all forms had the same effect.
The findings were presented to the Experimental Biology conference in Washington, DC, and the research was part-funded by the National Institutes of Health.
小题1: What’s the reason that adding low-calorie vegetable soup to the start of a meal can actually help to lose weight?
A.You can take in large quantities of vegetables. |
B.You can absorb high calories from the soup. |
C.You can take in low calories from the soup. |
D.You can feel full soon after having the soup. |
A.chicken stock | B.cauliflower | C.cream | D.carrots |
A.Vegetable Soup Helps to Lose Weight. |
