Question

SAT语法求助
1.Television's programming difficulties,(already made acute by rising costs,threaten) to become even more severe as a result of lobbying by special-interest groups.
这是正确答案,为什么用acuter就不行了呢?
2.Given her strong sense of social justice,Burns vehemently protested over her party's failure to support a tax decrease for senior citizens.
这里protested over哪里错了呢?
3.Professor Chen repeated her point that the hero,if given the chance to relive the moment,would choose to do it.
这里do it哪里错了?
查了下牛津高阶，acute的比较级的确是acuter
而且一楼protest over可以，protested over怎么就不可以了呢？再说我查的到用protested over的例句啊。

Answer 1

1.acute 的比较级不可以写作acuter,只能是more acute.英文里并不是每个形容词的比较级、最高级都是在原级上加 -er 和 -est,有一部分只能用 more,most 表达.
2.只能说protest over 或 protested,protested (protest的过去分词) 后面不可以跟 over.
3.正确答案应该是 do so 或者 relive it,不能选 do it 大概是因为it 一般修饰名词,而 relive 是动词.
补充：
我查了美国常用的两个字典,一个有acuter一个没有,但是如果你在网上打acuter或acutest 一般搜不出例句,也就是说不常用（基本不用）.acute这个词源于拉丁文,一般拉丁文演变过来的词都不可以用-er 和 -est,而用 more/most.
有些人不知道protested over 不对,理所当然地觉得可以写protest over 当然也可以写 protested over,所以会有这样的例句出现.protest over 是一种俚语词组,成分是特定的,比如说你可以说 sandwiched between （意思是说被两方夹在中间,像夹在三明治里一样）,却不可以说 sandwich between 或 sandwiching between.
我刚才又看了一遍第二题,答案应该是 protested (没有over)
