　　答案與題解：

　　1. A通過上下文可知此處應(yīng)為"年齡".

　　2. B bring about意思是"帶來"，bring in意為賺取，實(shí)現(xiàn)(一定利潤)，沒有bring to這個短語，如果用with，此句話必須變成what has it brought with these changes才符合語法，但意思就不符合文章了。

　　3. D life span是一個固定搭配，意為壽命。

　　4. B從下一句可以看出此處應(yīng)指那些不治之癥。

　　5. D本句舉了天花的例子，下一句指出很多孩子死于這些病，所以此處應(yīng)為一個表嚴(yán)重的詞。high是形容詞，不能修飾后面的形容詞。Acute不是比較級，所以and后面也不應(yīng)用比較級。

　　6. A本句后部分說在一些國家這些病已經(jīng)消失，通過常識得知應(yīng)該是發(fā)達(dá)國家。

　　7. C本句后部分說在一些國家這些病已經(jīng)消失，整段都在說明情況好轉(zhuǎn)，故選C.

　　8. B 冒號后面列舉的內(nèi)容不能統(tǒng)一用其他幾個詞概括，只能用factor.

　　9. C注意這里的which不是非限制定語從旬中指代前面l句話的作用，而是指代前面兩項(xiàng)內(nèi)容：衛(wèi)生的改善和抗生素的發(fā)明使用，所以which后的動詞不用三單形式。cause沒有這樣的語法搭配。

　　10.A該選項(xiàng)為固定搭配，意為對某種疾病的預(yù)防接種。

　　11.C前面說的是對疾病的防范和控制加強(qiáng)，后面說的是整體環(huán)境的改善，兩者為并列關(guān)系，但是And在書面語中不能這樣使用，所以只能選in addition.

　　12.D整句話的意思是：從基因角度看，人都能活到85歲，但是雖然現(xiàn)在人們壽命確實(shí)比以前長了，仍然有一些疾病使得我們不能都活到那個歲數(shù)。所以此處應(yīng)該填一個轉(zhuǎn)折副詞。

　　13.A those指代流感和艾滋病等靠病毒傳播的疾病，those后面的動詞是過去分詞作定語。spread的過去分詞與原形相同。

　　14.C本句最后指出一些病越來越年輕化，所以此處應(yīng)選擇younger的反義詞。

　　15.B obesity是心臟病和糖尿病年輕化的重要原因，它和心臟病、糖尿病不是并列關(guān)系，而是因果關(guān)系，所以選擇leading to，現(xiàn)在分詞作結(jié)果狀語。
