1.now that表既然的意思.有语言环境之其要表达的内容是：既然努力了,就没有遗憾.
2.seeing is believing,固定表达,眼见为实的意思.
3.我个人认为3题最佳答案应该为D,I think这个短语作否定句时要将否定词提前,即I don't think,故排除B,C,need与go均为动词,故中间应加不定式to.
4因为后面eat用的是原型,故助于应为复数,CD排除,又因鸡不吃草,故选B.

1 AB表示转折，用when，后半句应用过去时。
2 宾语应用名词或动名词
3 如果没有I don't think 就应该选D need to，你需要干什么，现在you need go out for a walk with your dog变成一个从句。
4 因为eat是原型，说明前面的名词是复数这里只有sheep单复同型

1.D
由题意为 如果你尽了最大的努力就不会有遗憾。 没有转折意义，排除A、B
when “当...时” 显然不正确now that意为：既然，由于。强调原因的带来
的结果
2.D
与seeing对应
3.A
need作为情态动词使用
4.B
sheep单复数同形，句中需表示一类的动物而不...

1.now that 是既然的意思，though,although 都是虽然得意思，when意思是当...时候，根据句意：既然你已经尽力了，那就一点也不遗憾。所以第一题选D。
2.根据语法规则，首先排除A和C，因为be 动词后面不能直接接动词原形，to的后面应该接原形，seeing is believing。意思是百闻不如一见。还有一种表达方式：To see is to believe.这...

2.根据语法规则，首先排除A和C，因为be 动词后面不能直接接动词原形，to的后面应该接原形，seeing is believing。意思是百闻不如一见。还有一种表达方式：To see is to believe.这是一句熟语，所以选D.
3.这是关于否定转移，根据后面的句子意思说，你最好应该先完成你的作业，所以应该选肯定的，排除B和C，若need 是行为动词，后面，因为前面有否定，所以不能带不定式，得接动词原形，若是情态动词，可以满足题意，故选A.
4.由于谓语动词是often，属于复数形式，应该主语是复数，而sheep得单复数同形，chicken是不可数名词，后面谓语用三人称单数应该是eats，cow和horse应该加s变成复数形式才符合语法规则，所以唯一符合题意的是B选项。
希望你能满意我的回答。能力有限，仅此而已。
