Passage The Road Not Taken Two roads diverged in a yellow wood, And sorry I could not t

ravel both And be one traveler, long I stood And looked down one as far as I could To where it bent in the undergrowth; Then took the other, as just as fair, And having perhaps the better claim, Because it was grassy and wanted wear; Though as for that the passing there Had worn them really about the same. And both that morning equally lay In leaves no step had trodden black. Oh, I kept the first for another day! Yet knowing how way leads to way, I doubted if I should ever come back. I shall be telling this with a sigh Somewhere ages and ages hence:. Two roads diverged in a wood, and I - I took the one less traveled by, And that has made all the difference. Questions :

What is the title of the poem？

since the 1950s in 1990 in 1955

over three decades in 1933

V.S. Naipaul, a writer in search of roots and winner of Nobel Prize for literature in 1999, was born in Trinidad(1), the son of an Indian civil servant. In his childhood, he was first educated in his hometown and then Oxford University, where he studied literature. There he met Pat and they got married(2).(3), he has been based in England yet spent much time traveling around the world. Travels(4)have taken him around the world on a quest for home and for roots. Sir V.S. Naipaul, now 69, was knighted (授以爵位) by Queen Elizabeth(5). A critic wrote the following about him: "(He is) the wanderer who tries to go home, but is not taken in and is accepted by another home only so long as he admits he is a lodger there."

根据下面内容，回答题： Japan"s 24-hour convenience stores， already struggling with lagging

根据下面内容，回答题：

Japan"s 24-hour convenience stores， already struggling with lagging sales and growth， may soon face yet another threat——moves to limit business hours and close the stores late at night. The prefecture of Saitama， which borders Tokyo， may follow in the footsteps of the western city of Kyoto and urge convenience stores to close during late night hours in an effort to limit carbon dioxide emissions.

Kyoto， a former capital， wants to persuade convenience and other 24-hour stores to close late at night so as to improve evening views of the city and cut down on energy use. The Nikkei said closures could last from 11 p.m. to 7 a.m. The move is strongly opposed by the industry， which fears a withering impact on an already troubled sector also grappling with the. specter of a higher tobacco tax， which could hit overall sales.

"Even if we only operate the stores for 16 hours， we can"t stop the refrigerators，" said Toshiro Yamaguchi， the president of Seven-Eleven Japan Co. He said such cuts in operating hours wouldreduce each store"s profit by 20 percent. "If this happens， our current business model will lose its foundation. "

Analysts said that while it is difficult to estimate the potential impact of the move without a concrete plan， their overall impression was that it was likely to be negative. "This could cut profits and lead to less efficient operations and the increased loss of opportunities，" said Masafumi Shoda， an analyst. " But it depends on the store——urban stores do better than others. There are some in the countryside that are inefficient. ""

Which Japanese city was the first to try to limit convenience store hours？查看材料

A.Saitama.

B.Tokyo.

C.Kyoto.

D.Nagoya.

I was nervous—desperately nervous—about becoming car-free. But eight months ago our car wa

s hit, and the damage was so bad it had to be given up. And that s when I had an idea. Why not just give up having a car at all？ The more I thought about it, the more sensible it seemed. We have a railway station behind our house, a tube station 10 minutes walk away, and a bus stop at the end of the street. If any family in Britain could live without a car, I reasoned, then surely we were that family？ But my new car-free plan wasn t shared by my family. My teenage daughters were shocked. How would they get to and from university？ (A bus, I suggested.)What would their friends think about our family being "too poor to afford a car" ？ (I wasn t that bothered what they thought, and I suggested they take the same approach.) My friends, too, were astonished at our plan. Wasn t a car essential, when you had children？ What would happen if someone got seriously ill overnight and needed to go to hospital (erm...an ambulance？). People smiled, as though this was another of my mad ideas, before saying they were sure I d soon realise that a car wasn t a luxury, it was a necessity. Eight months on, I wonder whether we 11 ever own a car again. The idea that you "have" to own a car, especially if you live in a city, is all in the mind. I live—and many other people do too—in a community that has never been better served by public transport, and yet car ownership has never been higher. Do I really need a car？ The answer, for me, turned out to be no, and Im a lot richer because I dared to ask the question.

The author decided to live a car-free life______.

A．after his car was damaged beyond repair

B．after he was hurt in a terrible car accident

C．because maintaining a car was too costly

D．because the traffic jam was too much for him

V Our birth is but a sleep and a forgetting; The Soul that rises with us, our life s Sta

r, Hath had elsewhere its setting, And cometh from afar; Not in entire forgetfulness, And not in utter nakedness, But trailing clouds of glory do we come From God, who is our home; Heaven lies about us in our infancy! Shades of the prison-house begin to close Upon the growing Boy, But He beholds the light, and whence it flows, He sees it in his joy; The Youth, who daily farther from the east Must travel, still is Nature s Priest, And by the vision splendid Is on his way attended; At length the Man perceives it die away, And fade into the light of common day. VI Earth fills her lap with pleasures of her own; Yearnings she hath in her own natural kind, And, even with something of a Mother s mind, And no unworthy aim, The homely Nurse doth all she can To make her Foster-child, her Inmate Man, Forget the glories he hath known, And that imperial palace whence he came. VII Behold the Child among his new-born blisses, A six years Darling of a pigmy size! See, where mid work of his own hand he lies, Fretted by sallies of his, mother s kisses, With light upon him from his father s eyes! See, at his feet, some little plan or chart, Some fragment from his dream of human life, Shaped by himself with newly-learned art; A wedding or a festival, A mourning or a funeral; And this hath now his heart, And unto this he frames his song; Then will he fit his tongue To dialogues of business, love, or strife; But it will not be long Ere this be thrown aside, And with new joy and pride The little Actor cons another part; Filling from time to time his humorous stage With all the Persons, down to palsied Age, That Life brings with her in her equipage; As if his whole vocation Were endless imitation. VIII Thou, whose exterior semblance doth belie Thy Soul s immensity; Thou best Philosopher, who yet dost keep Thy heritage, thou E ye among the blind, That, deaf and silent, read st the eternal deep Haunted for ever by the eternal mind, Might Prophet I Seer blest I On whom those truths do rest, Which we are toiling all our lives to find, In darkness lost, the darkness of the grave; Thou, over whom thy Immortality Broods like the Day, a Master o er a Slave, A Presence which is not to be put by; To whom the grave Is but a lonely bed without the sense or sight Of day or the warm light, A place of thought where we in waiting lie; Thou little Child, yet glorious in the might Of heaven-born freedom on thy being s height, Why with such earnest pains dost thou provoke The years to bring the inevitable yoke, Thus blindly with thy blessedness at strife？ Full soon thy Soul shall have her earthly freight, And custom lie upon thee with a weight, Heavy as frost, and deep almost as life! Question: The above excerpt is taken from " Ode: Intimations of immortality from Recollections of Early Childhood" by Wordsworth. Analyze the excerpt with reference to the entire poem. Write about 200-300 words.
