M7U2Penicillin ::Another drug that has helped increase the standard of people's health is penicillin, which is considered by many to be one of the most important medicines in contemporary society. It was discovered by a Scottish scientist named Alexander Fleming in 1928. He noted that a dish in which he was trying to grow bacteria for an experiment looked abnormal--there was blue mould in it. It astonished him to see the bacteria surrounding the mould dead, which meant that the mould had killed them. Fleming tried this mould out on another bacterium and found that it killed the bacterium too. He immediately realized that the mould might have an application in treating illnesses caused by bacteria. He named the liquid made from the mould 'penicillin'. However, the development of penicillin as a drug faced two problems. First, he was unable to find a procedure to make penicillin pure enough to work as a medicine. Second, it was difficult to produce penicillin in the ample quantities needed to be effective. In 1940, two other scientists, Howard Florey (Australian) and Ernst Chain (German-born English), helped solve these problems, and managed to make and test the new drug in large quantities. Since the new drug was needed for World War II, the government approval process for penicillin was accelerated, and mass production began in 1944. Due to the widespread use of penicillin, many lives were saved during the war. If penicillin had not been available, many people would have died from sickness or even small wounds. Penicillin became the greatest drug of the 20th century, saving millions of lives. In 1945, the three scientists, Fleming, Florey and Chain, shared the Nobel Prize in Medicine for their work. Magic needles: Chinese acupuncture One of the most famous Chinese medical treatments is the art of 'magic needles', or Chinese acupuncture. It was developed long ago, perhaps as early as 2000 BC. There is evidence that acupuncture began during the Stone Age, when stone tools called bian (砭) were used to press areas of the body. As acupuncture developed, the simple bian stones were replaced by stone needles. Eventually, metal needles began to appear and took their place. There were nine different kinds of needles. These included a needle with a head like an arrow, used for making shallow holes in the surface of the skin; a needle with a round tip, used for pressing the tissue under the skin; a dull needle, used for tapping against pressure points; and a needle like a small sword, used for letting liquid out of body parts which had swollen up. These needles could be made of different metals, such as gold and silver. Some acupuncturists today still use gold and silver needles, but the majority use only stainless steel ones. The main needle now used for acupuncture is fine and sharp. Most of the others have been replaced by more complex medical instruments. For example, the needle looking like a sword has been replaced by a sharp knife that doctors use in operations. Acupuncture uses stainless steel needles that are put into the skin at certain points on the body so that a disease can be cured or a health problem solved. These points are called acupuncture points. When acupuncture was first practised, there were 365 such points. The number of acupuncture points was the same as the number of days in a year. However, over the last 2,000 years, this number has gradually increased to about 2,000. Some acupuncturists insert needles at or near the body part affected by the disease, while others select points according to the symptoms that the patient has. If you go to an acupuncturist, he or she will ask you questions about your medical history and your way of life. The acupuncturist will look at the colour of your skin and your tongue, listen to your breathing, and check your pulses. Western medicine only recognizes one pulse which indicates the heartbeat. However, according to traditional Chinese medicine, there are twelve different pulses, six on each wrist, and every one of them is connected with a major body organ or its function. By checking all the pulses, the acupuncturist can find out which energy channel does not have enough energy. Some of the medical problems that can be treated by acupuncture include severe pains, headaches, injuries, stomach problems and high blood pressure. Some people have also used acupuncture to treat smokers, alcoholics and people who are addicted to drugs. How acupuncture reduces pain is not clear. One theory explaining this phenomenon suggests that acupuncture blocks pain signals from reaching the brain. Another theory relates acupuncture to the production of chemicals in the body which reduce pain. A lot of people now subscribe to these theories. As a unique contribution of traditional Chinese medicine, acupuncture spread to many other Asian countries, such as Japan, as early as the 6th century. It was introduced to the West in the 17th century. Today acupuncture has become popular round the world, as have other traditional Chinese medicines. The World Health Organization recommends acupuncture as a good treatment for over forty medical problems. While doubts about its safety have faded away, interest continues to grow.ical components eventually became so small that, by the late 1960s, portable cassette players were developed, along with video recorders which were used by TV stations. By the late 1970s, video recorders small and cheap enough for home use were introduced. Sound and video go digital In 1982, the first CDs were made available. CDs are often used for storing and playing music because they have a much better sound quality than traditional records and cassettes. In 1993, the VCD was born, and in 1995, the DVD was invented. The DVD is now the standard for recording
为了更好地测试学生的综合英语能力,托福阅读考试在形式和内容上都进行了改革,新托福阅读在整体命题思路和出题套路上并没有太大的变化。也就是说考生要想在新托福阅读考试中取得好成绩,还是要把重点放在认真地做好考前的准备工作上,提高自己的英语综合能力,在把握新托福阅读考试思路,熟练运用解题技巧的同时,保证词汇量达到一定的水平。因此建议考生们一定要在备考的过程中配备新托福阅读的第一把剑——词汇。托福阅读考试中词汇题会占到三分之一的比例,也就是说每篇文章中基本会有4题左右的词汇题。而这些词汇题中的词汇基本上也不会是所谓的“变态词”。当然有的考生会说到时根据上下文内容猜出单词的意思不就可以了吗?但是很多考生会出现的一种情况是:题干中的单词能猜出什么意思,可是选项中的单词不认识,最终依然无法选出正确答案。以TPO 8中第二篇文章的题目为例:Paragraph 6: In view of these facts, scientists …Their calculation show that the impact kicked up a dust clout that cut off sunlight for several months, inhibiting photosynthesis in plants; decreased surface temperatures on continents to below freezing; caused extreme episodes of acid rain; and significantly raised long-term global temperatures through the greenhouse effect. This disruption of food chain and climate would have eradicated the dinosaurs and other organisms in less than fifty years.Question 11: The word disruption in the paragraph is closest in meaning to○ exhaustion○ disturbance○ modification○ disappearance有的同学对disruption一词并不认识,但是根据disruption所在句子的前一句话“他们的计算表明撞击扬起的灰尘遮挡了阳光达几个月之久,阻止了植物的光合作用,将陆地上的气温降到了零点之下,导致酸雨,通过温室效应造成了长期的、严重的全球升温”,考生们可以猜出该词为“扰乱”之意,但是再看选项,一些词汇量小的考生可能只知道最后一个单词的意思,而disappearance, 意为“消失”,又不可能是正确选型,因此这些词汇量小的考生们只能束手无策了。其实第一个选项为“耗尽、用光”之意;第二个选项为“打扰、妨碍”之意;第三个选项为“修改”之意,所以正确答案应该是第二个选项。其他题型的考查重点虽然不是词汇,但是词汇量缺乏依然会对题目的理解和答题造成影响,而如果考生们能够把这些单词都掌握好,那么考试的主动权当然也就掌握在自己手里了。现行新托福阅读考试对词汇量的要求约为8000左右,因此考生们一定要配备应试新托福阅读的第一把剑——词汇,要坚持把单词书完整“啃”下来并彻底消化,打好词汇量基础。当然要把一整本词汇书“啃”下并消化,除了勤劳,还要注意单词的记忆技巧,不能光靠“蛮力”,这样容易产生疲倦感和厌恶感,反而产生负面效果。考生们可以运用以下几种记忆技巧来背单词:★ 谐音记忆 如:lethal可记成“离骚”。★ 联想记忆 如:battlefield(战场)可以联想为“打仗battle的场所field当然就是战场啦”。★ 比较记忆 如:形近单词evolution和revolution相比,evolution比revolution少了个字母r, 这种情况下我们可以想evolution是革命之前的进化发展,所以少一个字母r。★ 发音记忆 如:exacerbate的音标为[gzsbet], 遵循了发音规律,考生掌握了该单词字母组合的发音规律,边读边背,就可以很轻松的记住它了。★ 词群记忆 如:在背choosier一词时,考生应同时想托福阅读中choosier的解释“demanding”一词。★ 拆分记忆 如:deforestation可以拆为前缀de-, 词根forest, 后缀-ation。★ 滚动记忆 如:如果背单词表,在第一天背了10个单词,那么第二天在背新的10个单词之前必须先复习第一天背过的10个单词;第三天在背新的10个单词前先复习前两天背过的20个单词,以此类推。另外考生们在背单词的过程中需要通过不断做题来复习阅读高频词,因为既然是阅读高频词,肯定在阅读的文章中是反复出现的。当然也会有很多同学说背词汇书太有挑战性了,背过之后特别容易遗忘,而且也感觉枯燥无味,所以考生们如果不喜欢背词汇书,建议考生也可以精读OG或者TPO中的文章,因为所谓的新托福阅读高频词当然就是在新托福阅读文章和题目中会反复出现并考到的单词。
反正就要开学了等发书下来记也不迟啊`不然就买参考书那上会有重点单词以及单词用法的
