6、，以致你的身体不能再抵抗疾病。这种疾病到了这个阶段就叫艾滋病。如果你得了艾滋病，幸存的可能性很小。HIV是通过血液或性交时产生的液体传播的。携带病毒的血液或性交时的液体必须通过皮肤上的创口或通过注射才能进入人体，使人受感染。将来总有一天，科学家会找到医治HIV病毒或艾滋病的方法的。在找到之前，你必须保护你自己。你可以按照这里列举的一些注意事项去做，以确保自己的安全：If you inject drugs：do not share your needle with anyone else.

9、血液可能会留在针头内外。如果某人有HIV病毒，而你又用了同一个注射针，你就有可能把病毒注入你自己的血液中。在注射药物时，不要使用别人用过的其他任何东西。血液可能会溅到这些物品上来。假如你同一个男人或女人性交：要使用避孕套。它可以防止性交时产生的液体的传入。The following statements are NOT true.A person cannot get HIV the first time they have sex. WRONG. If one sexual partner has HIV, the other partner could become infected.Yo

13、you will get HIV/AIDS. WRONG. You can only get the disease from blood or sexual fluid. Unfortunately, people with HIV sometimes lose their friends because of prejudice.

15、明显的如果你同艾滋病患者拥抱、接触或亲吻，或者去他们家做客，你就会(从他们那里)感染上HIV病毒或得艾滋病。错了。你只可能通过血液或性交时的液体传染上这种病。不幸的是，由于偏见，HIV病毒携带者有时会失去他们的朋友。许多人担心他们会从HIV病毒携带者或艾滋病患者那儿染上HIV病毒或感染上艾滋病。由于相同的理由，有些艾滋病患者在生病时找不到任何人来照顾他们。蚊子可以传染HIV病毒和艾滋病。错了。(目前)还没有证据说明这一点。Step 1Read the text and answer the following questions.1Scan the text and choose the main idea for each part.Part 1AWays to protect yourself.Part 2 BSome wrong statements about AIDS.Part 3 CBackground information about HIV/AIDS.答案：Part 1C, Part 2A, Part 3B2The passage tells us abou
