请问老师，今天看到一道改错题:
My uncle is a person worth respect. 答案是把respect改为respecting，但是worth后面不是既能接名词又能接doing吗，比如worth
a visit和worth visiting，那这里respect不可数名词感觉也对呀。麻烦老师解答，谢谢!
'You're always -ing' means that you do
something very often, more often than the speaker thinks is normal or
reasonable. 如果将than看作准关系代词，那么这句话就是嵌入式关系分句。要是按比较分句分析呢？省略了什么内容？
我对下面这句不太理解，重点是括号内的解释不太理解——此句摘自夸克《英语语法大全》p829:The situation is only [即：merely] that (he’s thinking about marrying a fellow doctor). [即你不可以为，比方说，他是在为一个疑难病人操心]
...er person's speech, and much less than do the features that are common to all speakers.请问：(1) 如何理解 in which? 为什么要加 in?(2) no more than 和 much less than 后面为什么要加 do？
I bought a pair of shoes _______.A. at the half price B. at half the priceC. half as the priceD. the half at price正确答案：B，我选的是：A。我不明白 A 为何不对呢？烦请老师帮忙指教。谢谢。

In fact, our life ( )a lot in the past 30 years.A.is changedB.has been changedC.changesD.has changed本题选D，请问老师为什么不用被动？还有就是如果用一般现在时有错么？强调改变是一个客观现实，这么理解行么？谢谢老师。
