题目内容

The food we eat seems to have a great effect on our health．Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat．Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well．That food is related to illness is not a new discovery．In 1945,some researchers realized that things commonly used to keep colors in meats and other food additives caused cancer．Yet, these additives remain in our food, and it is difficult to know which things on the wrappings of foods are helpful or harmful．The additives which we eat are not all so direct．Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows．Sometimes similar things are supplied to animals not for their health, but just to make a profit．

The farmers are simply trying to fatten the animals in order to get a higher price on the market．Although some countries have tried to control such things, the practice continues．

Although the Garden God had made him the most beautiful place that there could ever be, Adam was lonely.

Adam needed some . So God reached into the ground again and took some more stuff from the earth. This time he made every kind of animal and every kind of bird. He brought them all to Adam to see he would call them. It must have a long, long time to think up all those ! Luckily, he didn't call them things like 'Foo Foo' or “Snuggems”or 'Pooky' or anything like that. , he called them 'gerbils' and 'rabbits' and 'rhinoceroses'. And he the birds 'eagles' and 'egrets' and 'ruby throated warblers'.

Well, , we don't know what Adam named them, he didn't speak English. But he named each kind, and that's important because people are the only ones that name things. Your knows what a squirrel is, but he doesn't call a squirrel. He just barks it! But naming things is one of the things that shows we are from all the other creatures that God made.

even with all the animals around to keep him company, God saw that Adam was sad. Monkeys are fun to play with, but they don't have very much to say and they have table manners. So God made Adam fall , and while Adam was sleeping, God took one of his ribs(肋骨).God took Adam's and he made a woman from it. When Adam woke up, God Eve to him , and Adam said, “At last! Here is like me! Her bones were made from my bones, and her body was made from my body. I will call her 'woman' because that means she was taken out of man.”

At last Adam was . And so Adam and Eve lived together in God's garden.

Hi Christine,

Sorry I haven’t emailed lately —I’ve been very busy since becoming a volunteer for the Riding for the Disabled Association.

Every Saturday, I help to get the horses ______51_____ for the disabled(残疾) riders. Many more disabled people want to ride _____52______ than you’d imagine. It’s a disadvantage that I don’t know how to ride —I’d love to get on long rides with the riders— but I’ll learn _______53____. Right now, I’m just happy to be able to lead the horses around for the disabled riders.

I’m ______54_____ helping to organize a sale, which will be _____55______ next month. It’s a lot more work than helping the disabled. I need to collect second-hand things to sell at the sale. There are _____56______ things available(获得的) than I thought, but I’m sure we’ll have ______57_____ next month.

I hope the sale raises more money than last month’s walk. It was rainy, so too few people took part in the event. Last week, we held an auction(拍卖). The auction took much less _____58______ to organize than the walk. _____59______, for some reason, people offered too little money for the things, so we didn’t raise enough money.

I’m ______60_____ you some pictures in the letter, as well as a speech I gave last week. Robin

People often eat food to feel better. Recently, researchers have found that eating chocolate or drinking water can reduce pain, and reduce a rat’s response to heat.

The study was done by Professor Mason and Professor Foo at the University of Chicago. It is the first to show that this powerful painkilling effect occurs while the animals are ingesting(吸收) food.

In the experiments, rats were given either a chocolate chip to eat or had sugar water or common water flowed directly into their mouths. As the rat ate the chocolate or fluid, a light under the cage was turned on. It was done to provide heat that usually caused the animal to lift its foot off the floor. The researchers found that rats were much slower to raise their feet while eating or drinking, compared to tests done while they were not eating.

Surprisingly, the researchers found no difference in the delayed foot-lift response when the rat was eating chocolate and when it was drinking water. Former research showed that only sugary things reduce people’s response to pain.

“This really shows it has nothing to do with calories,”Professor Mason said.“Water has no calories, but it has the same effect as chocolate chip. It’s really shocking.”

The researchers believe that this effect is also present in humans. The painkilling effect can be turned to our advantage. For example, water perhaps can take the place of candy which is often used to calm children—or even adults—in the doctor’s office.“Eating is a painkiller, but we don’t need the sugar,”Professor Mason said.“So replace the doctor’s candy with a drink of water.”

82.What’s the best title for this passage?

A.Chocolate is helpful to rats.

B.People can eat food to feel better.

C.A new way to kill pain is being studied.

D.Chocolate and water can reduce the pain response to heat.

83.Which of the following statements about the experiments is WRONG?

A.A light was turned on to provide heat.

B.The rats ate the chocolate with water.

C.Rats had slower response to heat after eating.

D.Some rats ate nothing during the experiments.

84.The underlined word“it”in Paragraph 5 refers to“ ”.

A.painkilling effect B.a chocolate chip

C.water D.the result of the study

85.Which of the following is an advantage that the result of the study can bring us?

A.Kids can eat a chocolate chip to reduce pain.

B.Adults can drink sugar water to reduce pain.

C.People can drink water to reduce pain.

D.People can reduce pain in the same way rats do.
