The human body is a living machine, and, like all machines, it needs "fuel" （燃料） to supply it with energy．This is provided by the food we eat．But how much do we need to stay healthy?
The energy value of food is usually measured in calories．A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃．The number of calories people need per day is different．Also, the number of calories you use at any one moment normally depends on the activity you are in．For example, you need more calories for standing than for sitting, more for running than for walking, and so on．
The energy in food is in the form of three kinds of chemical materials-carbohydrate（碳水化合物）, protein（蛋白质）and fat．Carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm, and fat 8．8 Cal/gm．Each food contains different amount of these materials, as the round pictures show．
1．The amount of calories supplied by equal amounts of milk, rice, and peanuts is the largest in the case of ________．
A．milk B．rice C．peanuts D．rice or peanuts
2．Choose one statement from among A-D that agrees with the passage and the pictures above．
A．You need more calories for swimming than for mountain climbing．
B．Food contains energy in the form of carbohydrates, proteins and fuel．
C．Different people need different amounts of energy depending on their age, sex and the activities they are in．
D．3 grams of milk provides 16．6 calories because carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm and fat 8．8 Cal/gm．
3．This article mainly tells us ________．
A．all the energy is in food B．the human body needs energy
C．the number of calories depends on your activity
D．we must only eat peanuts to get calories

III．阅读理解：（共20 小题，每小题2分，满分40分）
第一节：（共15小题，每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项A、B、C、D中选出最佳选项。
For her first twenty-four year, she’d been known as Debbie---a name that didn’t suit her good looks and elegant manner．” My name has always made me think I should be a cheerleader, ”She complained．”I just don’t feel like a Debbie!”
One day ,while filling out an application form for publishing job, the young woman suddenly changed middle name, Lynne, for her first name Debbie．“That was the smartest thing I ever did,” She says now．“ As soon as I stopped calling myself Debbie．I felt more comfortable with myself… and other people started to take me more seriously”．Two years after her successful magazine editor--- friends and associates call her Lynne．
Naturally, the name change didn’t cause Debbie/Lynne’s professional achievement--- but it surely helped if only by adding a bit of self-confidence to her talents．Social scientists say that what you are called can affect your life．Through history, names have not only identified people but also described them．”… As his name is, so is he …? says the Bible．For better or worse, qualities such as friendliness or reserves, simpleness or charm may be suggested by your name and encourage other people before they even meet you．
Of course , names with a good sense can work for you ---even encouraging new acquaintances．A recent survey showed that American men thought Susan to be the attractive female name, while women believed Richard and David were the most attractive to men．One woman I know turned down a blind date with a man named Harry because “he sounded dull．” Several evenings later she came up to me at a party, pressing for an introduction to a very nice man with whom they looked at each other all evening．“Oh, “ I said．” You mean Harry?” She was ill at ease．

B．was what she happened to do when filling out the form
C．did have an effect on her success
D．entirely contributed to her luck
2．The author introduced Harry to the woman___
A．at the request of the woman herself

Forty years ago, Rachel Carson died and the Pittsburgh area lost perhaps its most influential citizen．A native of a Pennsylvania College for Women graduate, Carson published “Silent Spring” in 1962, a work that launched the modern environmental movement and led to the creation of the Environmental Protection Agency （EPA） as well as the passage of our major environmental laws．
However, there has been a puzzling and troubling trend in recent years: an attack on her theory by conservatives and the agrochemical （农用化学品） industry．For example, Rush Limbaugh gave the following quiz: “Who caused more deaths: Adolf Hitler or RachelCarson?” Limbaugh's answer was Carson, due to the approximately 100 million deaths from malaria （疟疾） since 1972, the year in which the pesticide （杀虫剂）DDT was banned for use in the United States in part as a result of “Silent Spring．”
Therefore, on this 40th anniversary of Carson's death, we need to take a scientific look at the myths that remain about pesticides．
Myth 1: Pesticide usage has declined since 1962．In fact, pesticide usage has more than doubled since 1962, and the global pesticide industry currently uses over 2．5 million tons of pesticides each year．Even DDT is still used abroad．
Myth 2: Pesticides are safe．In fact, as Carson warned us, these poisonous chemicals are unsafe since they are designed to kill biological organisms, but are often not specific in their targets．Pesticide exposure can cause skin irritation, headache, cancer and even death．According to the WHO, over 25 million people a year in developing countries suffer severe acute pesticide poisonings with over 20,000 deaths．
Of the 80,000 pesticides and other chemicals in use today, 10 percent are recognized as carcinogens （致癌物质）．According to recent studies, brain cancer rates are five times higher in homes with “no-pest” strips and six times higher in homes where pets wear flea collars （杀蚤颈圈）．Our homes have pesticide concentrations 10 to 100 times higher than outdoors．
So, if Carson were with us today, still battling the agrochemical industry that spent millions of dollars, what would she be advocating? I feel confident that she would be a strong supporter of a new principle of chemical assessment．
Simply put, this principle requires producers of pesticides to prove that they are safe and necessary before they are put on the market．Our current system puts the burden of proof on government and scientists to prove that a pesticide is dangerous and poses an “unacceptable risk” before it can be pulled from the market．
1．Limbaugh attacked Carson because he thought that _____．
A．“Silent Spring” had caused in part the 100 million deaths from malaria
B．she was supporting the production of poisonous pesticides
C．“Silent Spring” was originated from Hitler’s writings
D．she had not cared for the 100 million deaths from malaria
2．Which of the following is the content of Myth 1?
A．The production of pesticides has doubled during the past 40 years．
B．2．5 million tons of pesticides have been produced since 1962．
C．The usage of pesticides has been dropping since 1962．
D．Pesticides have become less poisonous since 1962．
3．The author mentions “flea collars” in the sixth paragraph to indicate _____．
A．pesticides contribute to the development of cancer
B．the close connection between them and dog cancer rates
C．the medical effect of flea collars on dogs
D．flea collars contribute to high pesticide concentrations indoors
4．What is the suggested new practice of chemical assessment?
A．Government should prove a pesticide is unsafe．
B．Scientists should be responsible for writing assessment reports．
C．Producers of pesticides should provide proof of their safety．
D．A special committee should be set up for chemical assessment．

About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table．I couldn’t help overhearing parts of their conversation．At one point the woman asked: “So, how have you been?” And the boy, who could not have been more than seven or eight years old, replied, “Frankly, I’ve been a little depressed lately．”
This incident stuck in my mind because it confirmed my growing belief that children are changing．As far as I can remember, my friends and I didn’t find out we were “depressed” until we were in high school．
The evidence of a change in children has increased steadily in recent years．Children don’t seem childlike anymore．Children speak more like adults, dress more like adults and behave more like adults than they used to．
Whether this is good or bad is difficult to say, but it certainly is different．Childhood as it once was no longer exists, why?
Human development is based not only on innate（天生） biological states, but also on patterns of access to social knowledge．Movement from one social rote（生搬硬套） to another usually involves learning the secrets of the new status．Children have always been taught adult secrets, but slowly and in stages: we tell sixth graders things we keep hidden from fifth graders．
In the last 30 years, however, a secret-revelation（揭示） machine has been brought in 98 percent of American homes．It is called television．Television passes information to all viewers alike, indiscriminately （不加区分地）．Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures．
Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access．Reading and writing involve a complex code of symbol that must be memorized and practices．Children must read simple books before they can read complex materials．
1．Traditionally, a child is supposed to learn about the adult world______________．
A．through contact with society
B．naturally and by biological instinct （本能）
C．gradually and under guidance
D．through exposure to social information
2．The phenomenon that today’s children seem adult like is due to ____________．
A．the widespread influence of television
B．the poor arrangement of teaching content
C．the fast pace of human intellectual development
D．the constantly rising standard of living
3．Why is the author in favor of communication through print for children?
A．It enables children to gain more social information．
B．It develops children’s interest in reading and writing．
C．It helps children to memorize and practice more．
D．It can control what children are to learn．
4．What does the author think of the change in today’s children?
A．He feels amused by their premature （早熟） behavior．
B．He thinks it is a phenomenon worthy of note．
C．He considers it a positive development．
D．He seems to be upset about it．
