    The African elephant, which is the largest land animal remaining on earth, is of great importance to African ecosystem. Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the- forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.

    It is the elephant's great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.

    Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.

    What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

(1)、What is the passage mainly about?
A、Disappearance of African elephants. B、The effect of African elephants' search for food. C、Forests and savannas as habitats for African elephants. D、The eating habit of African elephants.
(2)、What does the underlined phrase "setting the terms" most probably mean?
A、Fixing the time. B、Deciding the conditions. C、Improving the quality. D、Worsening the state.
(3)、What do we know about the open spaces in the passage?
A、They result from the destruction of rain forests. B、They provide food mainly for African elephants. C、They are attractive to plant-eating animals of different kinds. D、They are home to many endangered animals.
(4)、The passage is developed mainly by_____
A、giving examples B、pointing out similarities and differences C、describing the changes in space order D、showing the effect and then explaining the causes
举一反三
阅读下列短文,从每题所给的四个选项中(A、B、C、D)中,选出最佳选项。

    In one of the old buildings near our school,one could see an old man sitting by a large window on the first floor,His name was James.During the three years at school,I had hardly ever found him missing from his usual position.

He was a high-ranking government official and lived happily with his wife .Once there was a bus accident,in which a number of passengers were seriously injured and taken to the hospital for treatment.James was responsible for the rescue operation.It was a big hospital,but James was shocked to notice how ill-equipped it was.There was no enough life-saving drugs and life-supporting equipment.The injured and their companions had to struggle there .James attempted to help .However,though he emptied his pockets,many of them died that day.

That was a turning point in his life.He made a decision to devote his life to helping others,particularly the poor and needy patients and their companions.He began to spend much of his income on these people.Since this required much time and energy,he found it difficult to fulfill his official duties and therefore chose to retire,which,in turn,reduced his income considerably.

His wife was deeply worried.Most of the time,James was out and paid least attention to home affairs.Meanwhile,as he was spending a lot helping others,she had struggle even to meet the household expenses.Though she was not against his helping the poor,she urged him not to ignore his own home and life,but it had no effect on him.She decided to leave him ,never to return.Though he continued his work, this was a great blow and did serious harm to his health and enthusiasm and he was soon forced to stay indoors.That was when he took his position by the window,spending his time looking outside.

    A few weeks after my graduation,I returned to school,only to find the building gone.I heard that they were torn down.Everyone left except James.He refused to go and the next morning,he was found at his usual place by the window,dead.

    Depression(抑郁) can be a destructive illness, plaguing millions of people worldwide with feelings of sadness, hopelessness, and fatigue. Despite numerous antidepressant drugs, as many as a third of patients don't respond to medication. This has forced doctors to be more creative in finding different treatments for the condition.

    In the past two decades, researchers have tied depression to a seemingly unrelated condition: inflammation(炎症), the body's natural response to stress. It could rise from injury or inflection, or even emotional issues like an unhappy marriage or problems at work. Some amount of inflammation is generally beneficial, as it increases production of cytokines(致癌因子),proteins that help us heal and protect us from the effects of overwork.

    But excessive cytokine levels, and the inflammation they bring on, could come at a cost—a number of studies suggests that high levels of cytokines could contribute to depression.

    Cytokines can reach the brain several ways: directly through the blood-brain barrier or indirectly by binding to nerve fibers elsewhere, which send signals to the brain to produce the inflammation molecules. In the brain, cytokines can disturb the production and release of several important signaling chemicals, including serotonin, dopamine and glutamate, which help control emotion, appetite, sleep, learning and memory. It's though that a lack of serotonin activity in the brain causes depression; most antidepressants increase the activity. But cytokines also have been shown to activate stress hormone signaling in the brain, which man also serve to develop depression.

    With all the evidence implicating inflammation in depression, doctors have been anxious to test anti-inflammatory drugs as a potential treatment. Four small studies published between 2006 and 2017 by research groups in Europe and Iran found that adults diagnosed with depression who took aspirin or another anti-inflammatory drug called Celecoxib, along with an antidepressant, got more relief from feelings of sadness, hopelessness, guilt and fatigue compared with those taking an antidepressant alone. However, Andrew Miller, a professor of psychiatry at Emory University, thought something was wrong in these small, limited studies. None of them looked at whether the participants had to have high levels of cytokines before they'd see a benefit from anti-inflammatory drugs.  "Unfortunately, much of the field has fallen into the trap of viewing inflammation as the be-all, end-all," Miller says. He and his colleagues wanted to see whether the effect of these drugs was limited to the depression patients with high cytokine levels, or if it helped all people diagnosed with depression.

    Little Women is the best-known work of author Louisa May Alcott. Published after the end of the Civil War, the book is about the lives of the author and her sisters. Although it was her most successful work, it was not her first.

    Alcott began writing at the age of 20, when she published her poem “Sunlight”. Throughout her early career, she wrote many poems and short stories for magazines. At the age of 22, she began to write fairy tales, romantic thrillers, and other novels, mostly to earn money. At a time when few opportunities were open to women, Alcott supported women's right to work. With her small income, she had long provided for her family.

    When the Civil War broke out, Alcott, at the age of 30, joined the war effort to fight against slavery. She had originally wished to serve as a soldier. However, women were not allowed in battle at that time. As a result, she became a Civil War nurse. Alcott's work as a nurse served as a milestone (里程碑) in her writing career.

    In December of 1862, she left New England to work in the Union Hotel Hospital in Washington, DC. There were few supplies, and doctors performed operations without painkillers. The conditions for patients and doctors were terrible. Within a few weeks, Alcott herself became so ill that she nearly died. She returned home and recovered slowly over a period of months.

    As soon as her health improved, Alcott started a new project. The letters she had sent home became the basis of a newspaper series about her experience as a Civil War nurse. She wrote about her tasks, the wounded soldiers she looked after, and the difficulties they faced. The series, Hospital Sketches, was a success, which received praise from readers and critics (批评) at the same time. Although her best-known work was yet to come, the success of Hospital Sketches marked the achievement of her dream to become a popular author.

    Imagine being a business that regularly takes huge quantities of your own products worth millions of pounds and burns them up. Your stock literally goes up in smoke. It sounds crazy, but the practice is common for some of the world's biggest clothing manufacturers. They argue that it is the most cost-effective way of maintaining their brand's exclusivity (独特性).

    The clothes that are burned are those that do not sell at a high enough price. Rather than watch them go on sale, the companies would set fire to them and regain a small amount of energy.

    Nobody knows exactly how much unsold stock is burnt annually by those fashion houses, but burning clothes has various negative impacts on the environment. For example, burning clothes made from artificial fibers may release plastic microfibers into the atmosphere, which worsens global warming. A U.K. parliamentary committee report on sustainability and the fashion industry advises the government to ban the burning of unsold stock if it can be reused or recycled.

    Actually, there are other approaches. What if those companies had a section tasked with taking back unsold clothes, redesigning them into new products, and shipping out the new products to the market once again?

    There is also now an opportunity to focus on biodegradable (可生物降解的)fabrics. Clothes that break down faster might not have to be burned. They would also appeal to those who care about the environmental impact of their own wardrobes.

    Additionally, we have an over-production problem. According to the World Bank, while clothing sales have risen steadily since 2000, clothing utilization has fallen at roughly the same rate. For every extra T-shirt that is sold, it will be worn roughly half as much as it would have been 20 years ago. That means better forecasting market trends would in theory result in less waste.

    Burning clothes won't happen simply through fashion firms. The scale of fashion production has to change. And it's important to recognize that these consumer-focused brands will only go where the market takes them. If protecting the environment really matters to the public, they have to make clear that they want more sustainable clothing in the first place. Without consumers demanding that, it won't change.
