“Originally, my friend and I had always planned, just for the fun of it, to drive across the country—no reason, just for fun for our senior year ， ” Elliot explained.“But, when I found out that fact, I realized we could use it for something good, and not just our own pleasure.And, through that, the idea of building schools came around, you know, spreading awareness is a major goal.” Elliot spread the word that he was looking for people to share his mission of educating young Americans, and getting them involved.An anonymous donor gave him the bus.And about 30 people applied for the trip.Elliot helped select four of them, ages 17—23.
The five share one mission—educating young Americans about the AIDS crisis in Africa.
Eighteen-year-old Nathaniel Elliot came up with the idea after he learned a sobering fact.

高中英语Unit 3 Protecting ourselves--Grammar and usage

Unit 3 Protecting ourselvesGrammar and usageStep 1 General introductionThe grammar items in this unit focus on one aspect of the structure of a text—the development of a text. You will learn how a text should be written to allow readers to move from one idea to the next easily. You will get to know that there are four features that can help develop a text logically. You are expected to apply what you have learnt to practice by finishing an exercise.Step 2 Explanation—the development of a text1. Turn your books to pages 34 and 35 and have a look:T: How many paragraphs are there in the text?(There are ten paragraphs.)T: What is the title of the text?(The title is ‘Aids today’.)T: Can we learn whatthe text is about from the title?(Yes. We learn that the text is about the deadly disease of Aids at the present time.)T: If you are asked to divide the whole text into several parts, how will you divide it?(We can divide it into three parts. The first part is the introduction in the first paragraph. The second part is the main body and includes the next eight paragraphs. The conclusion is the last paragraph, and is the last part.)T: What is the main idea of the first part?(It gives us an example to show us how serious the situation of Aids is in Africa.) T: What is the second part about?(It tells us some detailed information abut Aids. For example, what causes Aids, the ways people get infected with aids, how serious the situation is around the world and what the UN and the Chinese government have been doing to deal with this situation.)T: What is the last part about?(It refers again to the example mentioned in the first paragraph and points out the key to stopping Aids in the future.)T: Now we can see how a text is developed. We know that a text usually includes several parts. We call these parts the title, the beginning paragraph, the body paragraphs and the concluding paragraph. Now, let’s go over the Grammar and Usage section to learn how to develop a text logically.2. Read the guidelines and Part 1. Can you also think of some titles of some other articles that are not too long and are clear and simple?3. Go over the three points of Part 2 and see what should be included in the beginning paragraph.4. Go over Part 3. This part will tell you that each body paragraph usually containsa topic sentences and a concluding sentence to the paragraph. Try to find what the topic sentence should be like and where it can be found, what supporting sentencesare, and what the function of a concluding sentence is in a paragraph.5. Read Part 4 and try to find how the concluding paragraph functions in a text.6. Do the exercise on page 41. Read the sentences and decide which paragraph they belong to and what type of sentence each one is.Answers:Step 3. Practice1. Now let’s e to Parts C1 and C2 on page 116 in Workbook, so that you can have more chances to practice what you have learnt in this section.2. Read the following passage and do the exercises as you are required to.Are There Extra-Terrestrials?(1)Many scientists today believe that life exists elsewhere in the universe—life probably much like that on our own planet. They reason in the following way.(2) As far as astronomers can determine, the entire universe is built of the same matter. They have no reason to doubt that matter obeys the same laws in every part of the universe. Therefore, it is reasonable to guess that other stars, with their own planets, were born in same way as our own solar system. What we know of life on earth suggests that life will arise wherever the proper conditions exist.(3) Life requires the right amount and kind of atmosphere. This eliminates all those planets in the universe that are not about the same size and weight as the earth.A smaller planet would lose itsatmosphere; a larger one would hold too much of it.(4) Life also requires a steady supply of heat and light. This eliminates double stars, or stars that burn up suddenly. Only single stars that are steady sources of heat and light like our sun would quality. Finally, life could develop only if the planet is just the right distance from its sun. With a weaker sun than ourown, the planet would have to be closer to it. With a stronger sun, it would have to be fartheraway.(5) If we suppose that every star in the universe has a family of planets, then how many planets might support life? First, eliminate those stars that are not like our sun. next, eliminate most of their planets; they are either too far from or too close to their suns. Then eliminate all those planets which are not the same size and weight as the earth. Finally, remember that the proper conditions do not necessarily mean that life actually does exist on a planet. It may not have begun yet, or it may have already died out.(6) This process of eliminate seems to leave very few planets on which earthlike life might be found. However, even if life could exist on only one planet in a million, there are so many billions of planets that this would still leave a vast number on which life could exist.The title ___________________________________________________The beginning paragraph _____________________________________Topic sentence _______________________________________________ Body paragraph 1 ____________________________________________Topic sentence _______________________________________________Body paragraph 2 ____________________________________________Topic sentence _______________________________________________Body paragraph 3 ____________________________________________Topic sentence ________________________________________________Body paragraph 4 _____________________________________________The concluding paragraph ______________________________________。

高中英语 Unit3 Protecting ourselves艾滋病素材牛津译林版选修10-牛津版

艾滋病后天免疫力丧失综合征，英文缩写词AIDS的音译，曾译为“爱滋病〞、“爱死病〞。

1981年在美国首次发现和确认。

病毒侵入后，人体即丧失免疫功能，容易感染其它疾病而死亡。

一般通过性接触、静脉注射及输血等途径传染。

被称为“20世纪的瘟疫〞。

[艾滋病病毒和艾滋病有什么区别]HIV 〔艾滋病病毒〕代表人类免役缺陷病毒。

一个人感染了 HIV 以后，此病毒就开始攻击人体免役系统，人体免役系统的一个功能是击退疾病。

经过几年， HIV 削弱了免役系统，这个时候，人体就会感染上机会性感染病，如，肺炎，脑膜炎，肺结核。

一旦有机会性感染发生，这个人就被认为是患了艾滋病。

艾滋病〔 AIDS 〕代表获得性免役缺陷综合征。

艾滋病本身不是一种病，而是一种无法抵抗其它疾病的状态或综合征状。

人不会死于艾滋病，而是会死于与艾滋病相关的疾病。

[什么是艾滋病〔AIDS〕]艾滋病，医学全名为“获得性免疫缺陷综合症〞〔Acquired Immune Deficiency Syndrome -- AIDS〕，是人体感染了人类免疫缺陷病毒〔HIV〕，又称艾滋病病毒所导致的传染病。

值得一提的是，HIV本身并不会引发任何疾病，而是当免疫系统被HIV破坏后，人体由于失去抵抗能力而感染其他的疾病导致死亡！通俗地讲，艾滋病就是人体的免疫系统被艾滋病病毒破坏，使人体对威胁生命的各种病原体丧失了抵抗能力，从而发生多种感染或肿瘤，最后导致死亡的一种严重传染病。

这种病毒终生传染，破坏人的免疫系统，使人体丧失抵抗各种疾病的能力。

当艾滋病病毒感染者的免疫功能受到病毒的严重破坏、以至不能维持最低的抗病能力时，感染者便发展为艾滋病病人。

随着人体免疫力的降低，人会越来越频繁地感染上各种致病微生物，而且感染的程度也会变得越来越严重，最终会因各种复合感染而导致死亡。

艾滋病主要通过血液、不正当的性行为、吸毒和母婴遗传四种途径传播。

国际医学界至今尚无防治艾滋病的有效药物和疗法。
