    【题目】 There are many gardening tips. Some suggest playing music for your house plants, having conversations with them, or even giving them a gentle touch now and then. Most of these practices are probably more for the benefit of the gardener than the garden, and generally harmless enough but except the last one. Your plants really dislike it when you touch them.

    A new study out of the La Trobe Institute for Agriculture and Food has found that most plants are extremely sensitive to touch, and even a light touch can significantly stunt(阻碍) their growth. “The lightest touch from a human, animal, insect, or even plants touching each other in the wind, can cause a huge gene response in the plant,” Jim Whelan, who led the new study, said. “Within 30 minutes of being touched, 10% of the plant’s genome(基因组) is changed. This involves a huge expenditure(消耗) of energy which is taken away from plant growth. If the touching is repeated, then plant growth is reduced by up to 30%.”

    Whelan and his team are still trying to find out why plants respond, at the genetic level, so strongly. They do have some theories, however. We know that when an insect lands on a plant, genes are activated(激活) preparing the plant to defend itself against being eaten ,” said Dr. Yan Wang, co-author of the study.

    Until more research is done, it’s just a guess at this point. Still, the findings might already lead to new methods for how agriculturalists deal with their crops, to best promote healthier growth.

    It’s worth noticing that while the study found that plants often respond to just a single touch in negative ways, it’s really repeated touching that causes lasting stunted growth. That’s because the plants are looking for patterns in the touching, to tell harmful touch from random touch. So it doesn’t matter if you accidently brush up against a bush during a walk through the woods.

    【1】How is the passage mainly developed?

    A.By comparing

    B.By giving examples

    C.By listing numbers

    D.By showing results of studies

    【2】Why can touching stunt a plant growing according to the study?

    A.It leads to the plant’s energy expenditure.

    B.It makes the plant sensitive to threats.

    C.It causes a genetic disorder in the plant.

    D.It prevents the plant absorbing nutrients.

    【3】What’s the importance of the study by Whelan and his team?

    A.It gives us more useful gardening tips.

    B.It helps find ways to ensure plants’ healthy growth.

    C.It contributes to the further study on genes.

    D.It uses data to warn people not to touch plants.

    【4】What is the passage mainly about?

    A.Something is done to help plants grow.

    B.Plants’ genome can be changed easily.

    C.Plants don’t really like to be touched.

    D.What we do every day may destroy plants.

    【题目】Directions：Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

    Job Discrimination against Women in China

    Nowadays, more and more women have walked out of kitchen and become career women instead of housewives. With the increase in the employment ratio of women in society, some subtle forms of job discrimination do exist.

    To begin with, quite a lot of companies intentionally control the number of female employees when they advertise for staff in the newspaper. Therefore, it is rather difficult for women, even with a master degree, to get well-paid jobs. Some enterprises definitely refuse female applicants, either to avoid their maternity leaves stipulated（规定）by our government when they give birth to a child, or because of the employers’ prejudice against women. Some bosses think women are inferior to men in professional skill and spirit of enterprise.

    Some companies do employ women staff, but inequality is always there like an increasable spot. Even when men and women are in the same position doing the same job, it is no easy task for a woman to be promoted or get equal pay. The employers take the biased attitude toward female employees, and usually think that a man is more capable than a woman. Sometimes they fire a woman without any good reason.

    In china, there is a saying“Women hold half of the sky”. But women are not given enough respect they deserve in their career. Since men and women are together playing the same important role in our whole society, our government, as well as the society, should take efficient measures to provide the same job opportunities to women. And the women themselves should enhance their work ethic and awareness of self-reliance and self-protection. In this way, more and more women can be motivated to work well at their favourite job and promoted to their desirable positions. Only in this way, can our society be called an equal, open and just one for everyone.

    【题目】At 27, after serving in World War II, I dreamed of owning a piece of land. So I moved from central Illinois to Shelbina, Missouri, and bought 236 acres for $6,000. The plot of land was situated on a dirt road and was half farmland and half trees, with an old house that had no running water or electricity. Obviously, it was not what you’d call prime real estate. But it was mine.

    I was alone for the first time in my life, and I found it liberating. My days were filled from dawn until dusk with plowing and planting corn. Dinnertime came and went, and I barely remembered to eat.

    I wouldn’t say I was a great success at farming in Missouri. However, when I went to the store to buy some plowshares, I met a nice woman named Claudette working behind the counter. I also ran into her at St. Mary’s Catholic Church in Shelbina each week. I found out later that her manager kept asking her about “that tall boy (and eligible bachelor) from Illinois living out in the country in an old house with no water, no electricity and no housekeeper.”

    Claudette and her sister soon visited my farm and put up some curtains. To show my appreciation, I took Claudette out for a ride in my 2-ton Studebaker truck. We married in 1954 and have now been together for more than 62 years!

    I later sold the Missouri farm for a $3,500 profit and bought 40 acres in Illinois. For many reasons, buying the Missouri farm was a good idea. I will always cherish memories of owning the farm and meeting my beloved.

    【1】When the author bought the plot of land in Shelbina, ________.

    A. it was well equipped B. he was unsatisfied with it

    C. it was not a real estate D. he worked very hard on it

    【2】The underlined word “liberating” in paragraph 2 can be replaced by the word ________.

    A. upset B. interesting

    C. free D. boring

    【3】The author regards buying the Missouri farm as a good idea because _______.

    A. he was able to sell it at the price of $3,500

    B. he could recall plenty of experiences in his own farm

    C. he got the chance to meet his wife working at a church in Shelbina then

    D. he could purchase another house in Illinois as a result of successful farming

They started it four years before to share a meal among someone, listen to them and figure out how they can help. Mike Campbell is one of the first people they took to lunch and we are still in touch. John or Chase know they can’t solve the homeless problem.
