解析
【分析】这道题考查if引导的真实条件状语从句的时态规则，核心遵循“主将从现”原则：即if引导的条件状语从句用一般现在时，主句用一般将来时（will+动词原形）。解题时，先确定每个句子的从句（if后的部分）和主句，再根据主语的人称、数，以及时态要求确定动词形式：从句主语是第三人称单数时动词用三单形式；从句否定句借助助动词does构成；主句统一用will加动词原形。
【解析】1. 从句主语为you，用一般现在时feel；主句用一般将来时will have，故填feel; will have。
2. 主句为疑问句，用一般将来时will see；从句主语he是第三人称单数，用一般现在时has，故填will; see; has。
3. 从句there be的主语fewer trees是复数，用一般现在时are；主句用一般将来时will be，故填are; will be。
4. 主句用一般将来时will dress；从句是否定句，主语he是第三人称单数，借助助动词does构成否定，故填will dress; doesn't work。
5. 从句主语Marcia是第三人称单数，用一般现在时lives；主句用一般将来时will keep，故填lives; will keep。
6. 主句用一般将来时will buy；从句主语the old one是单数，用一般现在时is，故填will buy; is。
7. 主句用一般将来时will fight；从句主语是they，用一般现在时argue，故填will fight; argue。
8. 主句用一般将来时will have；从句主语是I，用一般现在时need，故填will have; need。
9. 主句用一般将来时will send；从句主语he是第三人称单数，用一般现在时visits，故填will send; visits。
10. 从句主语Mr Green是第三人称单数，用一般现在时says；主句用一般将来时will feel，故填says; will feel。
