3.for a person to become infected，blood or sexual fluid that carries the virus，has to get inside the body through broken skin，or injection.(p22)
攜帶病毒的血液或體液必須通過(guò)皮膚上的創(chuàng)口或通過(guò)注射才能進(jìn)入人體，使人受感染。
句中有一個(gè)that引導(dǎo)的定語(yǔ)從句，修飾blood or sexual fluid；to become infected是不定式短語(yǔ)作person的后置定語(yǔ)。
4.here are some things you can do to make sure you stay safe.(p22)
你可以按照這里列舉的一些注意事項(xiàng)去做，以確保自己安全。
things后跟了一個(gè)定語(yǔ)從句you can do；動(dòng)詞不定式短語(yǔ)to make sure you stay safe表示目的，make sure后接賓語(yǔ)從句you stay safe，省略了連接詞that，stay 在此處是一個(gè)系動(dòng)詞，意為“保持”，后接形容詞。例如：
they are going to stay awake to see the lunar eclipse.
他們打算不睡覺(jué)等著看月食。
5.it is only when the disease has progressed to aids that a person begins to look sick.(p22)
只有當(dāng)這種病發(fā)展成艾滋病時(shí)，人才會(huì)顯出病態(tài)。
it is/was...that/who...是強(qiáng)調(diào)結(jié)構(gòu)，它可以用來(lái)強(qiáng)調(diào)句中的某些成分，如主語(yǔ)、賓語(yǔ)、狀語(yǔ)等，但不能用來(lái)強(qiáng)調(diào)謂語(yǔ)和表語(yǔ)。原句是： a person begins to look sick when the disease has progressed to aids.
6.women are slightly more likely to become infected than men.(p22)
女性感染病毒的可能性比男性稍微大一些。
be likely 后接不定式或從句，表示“可能會(huì)……”。如：
he's likely to arrive late this afternoon.
他今天下午可能會(huì)遲到一會(huì)兒。
it's likely that they will camp out tonight.
他們今天晚上可能要在外面露營(yíng)了。
