2.Text 3The full influence of mechanization began shortly after 1850, when a variety of machines came rapidly into use. The introduction of these machines frequently created rebellions by workers who were fearful that the machines would rob them of their work. Patrick Bell, in Scotland, and Cyrus McCormick, in United States, produced threshing machines. Improve- meats were made in plows to compensate for different soil types. Stream power came into use in 1860s on large farms. Hay rakes, hay-loaders, and various special harvesting machines were produced, Milking machines appeared. The internal-combustion engine run by gasoline became the chief power source for the farm.In time, the number of certain farm machines that came into use skyrocketed and changed the nature of fanning. Be-tween 1940 and 1960, for example, 12 million horses and mules gave way to 5 million tractors. Tractors offer many. features that are attractive to farmers. There are, for example, numerous attachments: cultivators that can penetrate the s0il to varying depths, rotary hoes that chop weeds; spray devices that can spray pesticides in bands 100 feet across, and many others.A piece of equipment has now been invented or adapted for virtually every laborious hand or animal operation On the farm. lathe United States, for example, cotton, tobacco, hay, and grain are planted, treated for pests and diseases, fertilized, cultivated and harvested by machine. Large devices shake fruit and nut from trees, gain and blend feed, and dry gain and hay. Equipment is now available to put just the right amount of fertilizer in just the right place, to spray an exact row width, and to count out, Space, and plant just the right number of seeds for a row.Mechanization is not used in agriculture in many parts of Latin America, Africa, Agriculture innovation is accepted fastest where agriculture is already profitable and progressive. Some mechanization has reached the level of plantation agriculture in parts of the tropics, but even today much of that land is laboriously worked by people leading draft animals pal- ling primitive plows.The problems of mechanization in some areas are not 0nly cultural in nature. For examples, tropical soils and crops differ markedly from those in temperate areas that the machines are designed for, so adaptations have to be made. But the greatest obstacle to mechanization is the fear in underdeveloped countries that the workers who are displaced by machines would not find work elsewhere, Introducing mechanization into such areas requires careful planning.31. The first paragraph uses several examples to convey the ideas that______.A) the introduction of machines into agricultural work created rebellions on the part of the farmersB) the use of internal combustion engine as a chief power source for the farm produced great influenceC) the mechanization of agricultural work after 1850 gradually robbed many farmers of their workD) ingenious improvements were made in fanning machines in the 1860s to yield production

    Natural Medicines
    Since earliest days,humans have used some kinds of medicines.We know this because hu-mans have survived .Ancient treatments for injury and disease were successful enough to keep hu-mans from dying out completely.
    They were successful long before the time of modern medicine.Before the time of doctors with white coats and shiny(发亮的)instruments. Before the time of big hospitals with strange and wonderful equipment.
    Many parts of the world still do not have university-educated doctors.Nor do they have ex- pensive hospitals.Yet injuries are treated.And diseases are often cured.How?By ancient meth- ods. By medicines that might seem mysterious, even magical(有魔力的).Traditional medicines are neither mysterious nor magical,however.
    Through the centuries, tribal(部落的)medicine men experimented with plants. They found many useful chemicals in the plants.And scientists believe many of these traditional medicines may provide the cure for some of today's most serious diseases.
    Experts say almost 80%of the people in the world use plants for health care.These natural medicines are used not just because people have no other form of treatment.They are used be-cause people trust them.In developed areas,few people think about the source of the medicines they buy in a store.Yet many widely-used medicines are from ancient sources,especially plants. Some experts say more than 25%of modern medicines come,in one way or another,from nature.
    Scientists have long known that nature is really a chemical factory.All living things contain chemicals that help them survive .So scientists' interest in traditional medicine is not new.But it has become an urgent concern.This is because the earth's supply of natural medicines may be dropping rapidly.

    The passage indicates that ancient treatments for injury and disease were_____.
    A: much more successful than modern ones
    B: successful enough for humans to survive
    C: successful in all cases
    D: of little help to humans

    答案:B
    解析:
    第一段“…successful enough to keep humans from dying out completely”(有效地使人类免于完全消亡)与选项B“ successful enough for humans to survive”(有效地使人类生存下来)意思一样。短文中并没有对选项A的内容做比较,实际上也不可能笼统地做这种比较。选项C和D凭常识也能做出判断,绝对肯定和绝对否定都是错误的。

    问答题
    The celebrations of Easter have many customs and legends that have nothing to do with Christianity. Among various symbols associated with Easter, Easter bonny has been playing an important part. In pagan times, the “Easter hare” was no ordinary animal, but a sacred companion of the old goddess of spring, Eastre. The Easter bunny has its origin in pre-Christian fertility lore. The Hare and the Rabbit were the most fertile animals known and they served as symbols of the new life during the Spring season. Hares are animals which look like rabbits, but are larger and in many countries quite rare. In most places, the Easter rabbit (bunny) has replaced the Easter hare completely. Since long before Jesus Christ was born, parents told their children that the magic hare would bring them presents at the spring festival. The presents were often painted eggs, as these represented the new life starting at this time of year.

    正确答案:
    复活节节庆活动的许多习俗和传说都与基督教无关。在与复活节有关的各种象征性事物中,复活节野兔占有重要地位。在异教徒时期,复活节野兔并非凡物,它是春天女神Eastre的同伴。复活节兔子源于前基督教时期人们的生育知识。野兔与兔被认为是繁殖力最强的动物,因此象征着春天的新生命。野兔长得很像兔,但比兔大,在很多国家并不多见。在大多数地方,复活节兔子已完全取替了复活节野兔的地位。早在基督耶稣诞生之前,父母就告诉孩子有魔力的野兔会在春天来临的时候给他们带来礼物。礼物通常是彩蛋,因为它们象征着春天新生命的开始。

    正确答案: 1. factors 根据句意,没有破坏的土地、财富、自然资源和劳动力都是英国成为工业革命中心的重要因素。因此填入factors。
    2. But 通过后面的not enough可知,空格处应该填入表示转折的But。注意首字母大写。
    3. else 文章一开始就提到一系列因素,接着说这些因素还不够,由此可知,此处填入else,修饰something表示其他事物。
    4. establish/found/start 空格部分需填入动词与business organizations搭配。
    5. came/were 句意:工业革命中发明各种机器的人有着各种背景,从事各种职业。come from/ be from来自。注意此处需使用过去时态。
    6. more more...than...后跟形容词、副词、动词、名词等,且more后部分和than后部分词类相同,表示“与其说……不如说、是……不是、是……更是、有……无……”等。
    7. so so that表示结果。这里指科学家的工作不一定是要让他的发现能够被使用。
    8. that 空格部分填入that引导定语从句修饰不定代词something。
    9. through trial and error反复试验;不断摸索。这里填入through,意思为“通过,凭借”。
    10. of regardless of不顾,不管。
    11. inventors 通过上文介绍可知,发明家更倾向于发明实用的东西,而科学家的研究不一定能够被使用。因此该句应该填入inventors。
    12. few 此处填入few。a few“一些”,与上一句中的most of the people形成对比。
    13. in training in sth.关于……的培训。
    14. because 逗号后面的句子为前面的句子的原因,因此填入because。
    15. before 句意:甚至那些很少甚至没有接受科学培训的人也可能会发明东西,因为科学家数年前就已经奠定好了基础。years before数年前。
