Work Your Mind
Here’s something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later.
This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. “Don't be too quick to get help when learning something new,” education expert Manu Kapur told TFK. “Try to work on it yourself even if it means trying different ways.”
Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher’s help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher.
With the teacher’s help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution.
Kapur’s advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. “Simply doing a little work or nothing at all won’t work,” says Kapur. “The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible.”

While many of us may have been away somewhere nice last summer, few would say that we’ve “summered.” “Summer” is clearly a noun, more precisely, a verbed noun.
Way back in our childhood, we all learned the difference between a noun and a verb. With such a tidy definition, it was easy to spot the difference. Not so in adulthood, where we are expected to “foot” bills, “chair” committees, and “dialogue” with political opponents. Chances are you didn’t feel uncomfortable about the sight of those verbed nouns.
“The verbing of nouns is as old as the English language,” says Patricia O’Conner, a former editor at The New York Times Book Review. Experts estimate that 20 percent of all English verbs were originally nouns. And the phenomenon seems to be snowballing. Since 1900, about 40 percent of all new verbs have come from nouns.
Even though conversion (转化) is quite universal, plenty of grammarians object to the practice. William Strunk Jr. and E.B.White, in The Elements of Style — the Bible for the use of American English — have this to say: “Many nouns lately have been pressed into service as verbs. Not all are bad, but all are suspect.” The Chicago Manual of Style takes a similar standpoint, advising writers to use verbs with great care.
“Sometimes people object to a new verb because they resist what is unfamiliar to them,” says O’Conner. That’s why we’re comfortable “hosting” a party, but we might feel upset by the thought of “medaling” in sports. So are there any rules for verbing? Benjamin Dreyer, copy chief at Random House, doesn’t offer a rule, but suggests that people think twice about “verbifying” a noun if it’s easily replaceable by an already existing popular verb. Make sure it’s descriptive but not silly-sounding, he says.
In the end, however, style is subjective. Easy conversion of nouns to verbs has been part of English grammar for centuries; it is one of the processes that make English “English.” Not every coinage (新创的词语) passes into general use, but as for trying to end verbing altogether, forget it.
1.What can we learn about the verbing of nouns?
A.It hasn’t recently been opposed by many grammarians.
B.It is more commonly accepted by children than adults.
C.It hasn’t been a rare phenomenon in the past century.
D.It is easily replaced by existing verbs in practice
2.What is most leading experts’ attitude towards the practice of the verbing of nouns?
A.Cautious. B.Satisfied.
C.Disappointed. D.Unconcerned.
3.What does the author think of ending the verbing of nouns?
A.Predictable. B.Practicable.
C.Approaching. D.Impossible.
4.What is the best title for the text?
A.Are 40 Percent of all new verbs from nouns？
B.Are Summering and Medaling Annoying?
C.Are You Comfortable about a New Verb?
D.Are There Any Rules for Verbing?
In the atmosphere， carbon dioxide acts rather like a one-way mirror the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert's prediction， the atmosphere wilbe3C warmer in the year 2050thanitis today， if man continues to burn fuels at the present rate.If this warming up took place， the icecaps in the poles would begin to melt thus raising sea level several meters and severely flooding coastal cities.Also， the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球) ， possibly resulting in an alteration of the earth's chief food-growing zones.
In the past， concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic， which maybe affected by only a few degrees of warming：in other words， by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
However， most of the fuel is burnt in the northern hemisphere， where temperatures seem to be falling Scientists conclude，therefore，that up to now natural influences on the weather have exceeded those caused by man.The question is：Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and“cold”spots(that is， the relatively less hot spots) on the sun.As the sun rotates(旋转) ， every 27.5 days it presents hotter or“colder”faces to the earth， and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure， and consequently on wind circulation.The sun is also variable over along term：its heat output goes up and down in cycles， the latest trend being downward.
Scientists are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years， including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(惯性) of the earth's climate.If this is right，the warming effect of carbon dioxide might thus be serving as a useful counter-balance to the sun's diminishing(减少) heat.
1.Why is the fuel consumption greater in then or them hemisphere， but temperatures there seem to be falling?
A.Mainly because the levels of carbon dioxide are rising.
B.Possibly because the output of solar energy varies.
C.Because the inertia of the earth's climate take effect.
D.Possibly because the icecaps in the poles are melting
2.On the basis of their models， scientists are of the opinion that
A.the climate of the world should be becoming cooler
B.the new Ice Age will be delayed by the greenhouse effect
C.the man-made warming effect helps to increase the solar effects
D.it will take thousands of years for the inertia of the earth's climate to take effect
3.If the assumption about the delay of a new Ice Age is correct， .
A.the best way to overcome the cooling effect would be to burn more fuels
B.ice would soon cover the northern hemisphere
C.the increased levels of carbon dioxide would warm up the earth quickly
D.the greenhouse effect could work to the advantage of the earth
4.The purpose of the article is to explain .
A.the greenhouse effect
B.the solar effects on the earth
C.the models of solar-weather interactions
D.the causes affecting weather

The moment I stepped in high school, I have made up my mind to study hard for the purpose of entering the good university. In the first year, I made a lot of new friends, all of who were so excellent. I felt great pressure during the second year. My scores went up or down and I felt so worrying. I told me that I needed relaxation. Listen to music was a good way. Besides, I would like to talk my friends, because they understood me. We would have some tea in the shop and then share secret. When we laughed out happy, all the annoyance would disappear.
