At the railway stations all across Britain next week, groups of students will gather with their backpacks to wait for the trains that will carry them home for Christmas. This is a large movement of human beings as before, but with more contradictory traffic flows, so that trains filled with the young pass each other travelling in every direction.
At first, I went home every weekend with my washing, but then those visits became less regular. How did I let my parents know I was coming? They had no phone. Perhaps I wrote to them (“Expect me with dirty shirts this Friday afternoon”), but more likely I didn’t let them know, and just turned up or didn’t turn up, not understanding that my parents’ hopes of seeing me were a greater disappointment of my carelessness than a spoiled tea.
And in all this I suspect I was typical (有代表性的), at least of young men. As for our fathers and mothers, none of them talked of “empty-nest syndrome (综合症)”, even though its possible effect that the main human duty is to protect and feed the young would have suited their generation better than ours. Then, the feeling of loss went without a name. Today, it’s a condition with remedies, which will make parents feel more enjoyable in their life, The Mayo Clinic, for example, suggests you try to maintain regular contact with your children through “visits, phone calls, emails, texts or video chats”. If you feel unhappy, lean on (depend on … for support) loved ones or your mental health providers. Above all, stay positive: “Thinking about the extra time and energy that you might have to devote to your marriage or personal interests after your last child leaves home, it might help you adapt to this major life change.”
What can’t be denied, however, is that children often leave home. In modern societies, this is what they do. Christmas is the very time they can be depended on to return. For the non-religious, that may be this season’s true comfort and significance.
【小题1】The main reason for the busy traffic across Britain next week is that _______.

(D)
At a certain time in our lives we consider every place as the possible site for a house. I have thus searched the country within a dozen miles of where I live. In imagination I have bought all the farms, one after another, and I knew their prices.
The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the dollars and sold him the farm for just what I gave for it.
The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.
I was not really troubled by the loss. I had always had a garden, but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(无牵无挂). It makes but little difference whether you own a farm or not.

—“In the case of mild illness, patients should be provided with supportive care at home by a designated caregiver and only referred to health care facilities if they deteriorate or develop danger signs.
—Such danger signs may include: weakness or inability to stand, lethargy, unconsciousness, convulsions, very difficult or obstructed breathing or shortness of breath, inability to drink fluids, high fever.
—Treatment at home should entail(需要) rest, fluids(液体), medication for fever, and good nutrition, with patients kept separate from other people except one designated carer who should wash their hands and household surfaces frequently.
—It is more important in the home that patient wears a mask than the caregiver. The mask need not be worn all day and only when close contact with the caregiver is anticipated.
—If enough masks are available, caregivers should also use them to cover their mouth and nose during close contact.
—Windows should be kept open to allow good ventilation(通风).

In the 1920s demand for American farm products fell, as European countries began to recover from World War I and started austerity （紧缩） programs to reduce their imports．The result was a sharp drop in farm prices．This period was more disastrous for farmers than earlier times had been, because farmers were no longer self-sufficient．They were paying for machinery, seed, and fertilizer, and they were also buying consumer goods．The prices of the items farmers bought remained constant, while prices they received for their products fell．These developments were made worse by the Great Depression, which began in 1929 and extended throughout the 1939s．
In 1929, under President Herbert Hoover, the Federal Farm Board was organized．It established the principle of direct interference （干预） with supply and demand, and it represented the first national commitment to provide greater economic stability for farmers．
President Hoover's successor attached even more importance to this problem．One of the first measures proposed by President FranklinD．Roosevelt when he took office in 1933 was the Agricultural Adjustment Act, which was later passed by Congress．This law gave the Secretary of Agriculture the power to reduce production through voluntary agreements with farmers who were paid to take their land out of use．A deliberate shortage of farm products was planned in an effort to raise prices．This law was declared unconstitutional （违背宪法的） by the Supreme Court on the grounds that general taxes were being collected to pay one special group of people．However, new laws were passed immediately that achieved the same result of resting soil and providing flood-control measures, but which were based on the principle of soil conservation．The Roosevelt Administration believed that rebuilding the nation’s soil was in the national interest and was not simply a plan to help farmers at the expense of other citizens．Later the government guaranteed loans to farmers so that they could buy farm machinery, hybrid （杂交） grain, and fertilizers．
53．What caused the problem in the demand for American farm products?
A．The effect of the Great Depression．
B．The shrinking of overseas markets．
C．The destruction caused by the First World War．
D．The increased exports of European countries．
54．The word “successor” refers to ______．
A．President Hoover           B．US Secretary of State
C．President Franklin          D．US Secretary of Agriculture
55．The Agricultural Adjustment Act encouraged American farmers to ______．
A．reduce their scale of production        B．make full use of their land
C．adjust the prices of their farm products  D．be self-sufficient in agricultural production
56．The Supreme Court rejected the Agricultural Adjustment Act because it believed that the Act ______．
A．might cause greater shortage of farm products
B．didn't give the Secretary of Agriculture enough power
C．would benefit neither the government nor the farmers
D．benefited one group of citizens at the expense of others

At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse(粗糙的)wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have different exposures to environmental factors studying twins allows an “opportunity to control for genetic susceptibility(易受影响性),” Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors.
But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk.
Baron’s team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned(晒黑)without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal(异卵双生)and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status.
From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage.
Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors—such as smoking, being overweight, and unprotected overexposure to the sun’s damaging rays—may help motivate people to minimize these risky behaviors.
67．Which of the following is true according to the passage?
A．Jeanne and Susan share all the habits including smoking.
B．Skin aging is related more to environment and lifestyle than genetic factors.
C．Only identical twins can take part in the research.
D．Sunscreen use cannot help people have less skin damage.
68．Why did Baron’s team do the research on twins?
A．Twins are more likely to suffer from skin cancer.
B．It may guarantee the research is not influenced by genetic factors.
C．It gives others an opportunity to control twins’ genes.
D．It helps find twins are exposed to different environments.
69．What can you infer from the last paragraph?
A．This research makes people aware of dangerous lifestyles.
B．The environmental factors are unavoidable.
C．Being exposed to the sun is absolutely damaging.
D．There is little relationship between skin aging and environment.
70．The passage is mainly concerned with___________
A．skin cancer and environment
B．identical twins research
C．aging skin and environmental factors
D．genes and lifestyles
