Around the world, eggs have been a breakfast staple(重要部分)for all good reasons. After all, an egg is a storehouse of vital nutrients, making it an essential part of a healthy diet. And for those of you who are afraid of having this power food because you're worried that it will add to your weight, remember, one egg contains about 80 calories and about five grams of fat. Hence, smart consumption is a far healthier option.
Eggs are a well-known rich source of protein — an important building block of bones, muscles, skin, and blood. The body uses protein to build and repair tissues as well as making other body chemicals. Unfortunately, unlike fat and carbohydrates(碳水化合物), the body does not store protein, and therefore has no reservoir to draw on when it needs a new supply. Thus eggs are the perfect sources and a smart food choice for those who reduce their intake of carbohydrates in a bit to lose extra weight.
Another important nutrient you'll find abundantly in egg white is riboflavin or Vitamin B2. And for all of you wondering what's the benefit of this nutrient, Riboflavin is a water-soluble(水溶性) vitamin which is involved in vital processes in the body and is necessary for normal cell function, growth, and energy production.
The yolk, which many of us avoid out of fear, is actually a very healthy food, if consumed in moderation(适度). Mainly fat, the yolk contains 1.33 gm of cholesterol(胆固醇) per 100 gms and is a rich source of vitamin A, B vitamins, calcium, phosphorous(磷) and iron. Incidentally, the iron found in the yolk is easily digested in the body. According to nutrition experts, one can eat one whole egg every day without harming one's cholesterol and other blood-fat levels. But for those who crave for more eggs, you can reduce fat by having one whole egg and the whites of the rest of the eggs.
1.Eggs are regarded as important in breakfast because__________.
A. it is a custom to have eggs in the breakfast.
B. they are sold at a low price.
C. they are high in calories and low in fat.
D. they can provide people with many nutrients.
2.When our body is short of protein, we may____________.
A. feel tired and sleepy.
B. feel discomfort in our legs.
C. get tired of eating eggs.
D. be eager for other chemicals.
3.Which of the following is true about protein? .
A. It can’t be stored in the body.
B. Fat can be changed into protein.
C. It is a kind of carbohydrate.
D. Our body can only get protein from eggs.
4.We can infer from the last paragraph that____________.
A. the author suggests we only eat the whites of eggs.
B. eating enough yolk can reduce cholesterol in the body.
C. iron and phosphorous in the yolk are difficult to digest.
D. high blood-fat level can do harm to our health

Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.
One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe(津巴布韦), Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.
The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.
1.El Nino is known as ________.
A. the changing of the weather in southern Africa
B. the weather which brings drought (旱灾) to Africa
C. the warming of waters in the Pacific Ocean
D. the weather phenomenon that brings heavy rains to Africa
2.Scientists study El Nino in order that ________.
A. they can put all this information into their computers
B. they can tell why Zimbabwe has little or no rain
C. they can do some research work in this field
D. they can provide a kind of early warning to the place that will suffer from drought
3.Which of the following is TRUE according to the passage?
A. Scientists come to understand how El Nino appears.
B. Three scientists from the USA work on this subject.
C. El Nino has something to do with Zimbabwe’s poor crops.
D. Southern Africa suffered a serious drought and many people died from hunger.

Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable wind energy produced by man-made technologies.
One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity.
According to Pradhan’s proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.
Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains.
T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track.
A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province.
Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn’t taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device.
We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.
1.What can we learn about T-Box?
A. It will be fitted on the trains.
B. It is based on Pradhan’s idea.
C. It can turn electricity into light.
D. It was invented by an Indian scientist.
2.How much electricity can be produced per day by T-Boxes along a railway track of 100km?
A. 260 KWH. B. 2.6 KWH.
C. 150 KWH. D. 1.5 KWH.
3. It can be concluded from the last two paragraphs that ______.
A. T-Box has proved to be effective in harvesting wind
B. the maintenance of T-Box will be costly
C. there is much to do about T-Box
D. T-Box will come into use soon
4.According to the passage, which of the following statements is TRUE?
A. The Indian inventor Santosh Pradhan invented the speeding train.
B. The T-Box’s design won a silver medal in Lite-On Awards last year.
C. Rail travel has become one of the energy-efficient technologies in the world.
D. The India harvests 10,000 megawatts of electricity each day on average.
5.The passage is mainly written to _______.
A. encourage more people to travel by train
B. explain the advantages of electricity
C. tell readers how to save energy and money
D. introduce a new invention to readers

I had the meanest mother in the world. While other kids ate candy for breakfast, I had to have cereal (谷类食物), eggs or toast. While others had Cokes and candy for lunch, I had to eat a sandwich. As you can guess, my supper was different from other kids' too. But at least I wasn't alone in my sufferings. My sister and two brothers had the same mean mother as I did.
My mother insisted upon knowing where we were at all times. She had to know who our friends were and where we were going. She insisted if we said we'd be gone an hour, then we be gone one hour or less—not one hour and one minute. And she always insisted upon us telling the truth. Now you can see how mean she was.
The worst is yet to come. We had to be in bed by nine each night and up at eight the next morning. We had to wash dishes, make beds, and learn to cook. We had to wear clean clothes and take a bath, while the other kids always wore their clothes for days. I believe she laid awake at night thinking up mean things to do to us.
Through the years, things didn't improve a bit. We could not lie in bed, “sick” like our friends did, and miss school. Our marks in school had to be up to par(达到正常水平). Our friends' report cards had beautiful colors on them, black for passing, red for failing. My mother, being as different as she was, would settle for nothing less than ugly black marks.
As the years rolled by, we were one by one put to shame. We were graduated from high school. With our mother behind us, talking, hitting and demanding respect, none of us was allowed the pleasure of being a dropout.
My mother was a complete failure as a mother. Out of four children, a couple of us attained some higher education. And whom do we have to blame for the terrible way we turned out? You're right, our mean mother. She forced us to grow up into educated and honest adults.
Now I am trying to raise my three children. I am filled with pride when my children think I am mean because, you see, I had the meanest mother in the world.
1.What does the sentence “But at least I wasn't alone in my sufferings.” mean?
A.The author's mother was only mean to her.
B.The author's mother suffered her.
C.The author's mother was mean to her sister, brothers and her.
D.The author wasn't alone because of suffering.
2.Why was the author's mother mean to her children?
A.Because she wanted her children to be top students in school.
B.Because she wanted her children to bring home colored report cards like her friends did.
C.Because she wanted her children to drop out.
D.Because she wanted her children to do their best at school and be educated and respected citizens.
3.Which of the following statements is NOT true according to the passage?
A.Some of the children weren't able to go to college because of their mean mother.
B.Mother didn't let the author tell lies.
C.Mother asked the author to wear clean clothes.
D.The author could not miss school even if she was ill.

I had the meanest mother in the whole world. While other kids ate candy for breakfast, I had to have cereal, eggs or toast. When others had cokes and candy for lunch, I had to eat a sandwich. As you can guess, my supper was different from the other kids' also. But at least, I wasn't alone in my sufferings. My sister and two brothers had the same mean mother as I did.
My mother insisted upon knowing where we were at all times. You'd think we were on a chain gang. She had to know who our friends were and where we were going. She insisted if we said we'd be gone an hour, that we be gone one hour or less — not one hour and one minute.
We had to wear clean clothes and take a bath everyday. The other kids always wore their clothes for days. We reached the height of insults because she made our clothes herself, just to save money.
The worst is yet to come. We had to be in bed by nine each night and up at eight the next morning. We couldn't sleep till noon like our friends. So while they slept --- my mother actually had the nerve to break the Child Labor Law. She made us work. We had to wash dishes, make beds, learn to cook and all sorts of cruel things.

As the years rolled by, first one and then the other of us was put to shame. We were graduated from high school. With our mother behind us, talking, hitting and demanding respect, none of us was allowed the pleasure of being a drop-out.
My mother was a complete failure as a mother. Out of four children, a couple of us attained some higher education. None of us have ever been arrested or divorced. Each of my brothers served his time in the service of this country. She forced us to grow up into God-fearing, educated, honest adults. Using this as a background, I am now trying to raise my three children. I am filled with pride when my children call me mean. Why? Because now I thank God every day for giving me the meanest mother in the whole world.
