9、me disadvantages for people 4._ (live) in the countryside, including 5._ (low) levels of income and education, higher costs of healthy foods, and fewer sports facilities.Keys: 1.Personal 2. is considered 3.sharply4. living 5. lower分析1&2：这句话不难发现，and 并列的是两个句子前一句话It is calculated by dividing a persons

13、后面应该跟名词短语。所以live只能变成非谓语，那么到底是to live 还是living呢？ for people to live in the countryside 表示对于要去农村生活的人 for people living in the countryside 表示对于居住在农村的人 根据句意：这或许对于居住在乡下的人而言有些劣势。所以应该填living（非谓语作定语） 很显然and使 lower higher和 fewer并列.长难句中派生词的运用 If youre one of the millions of Americans who take a blood pressure
