在做托福语法的时候遇到点不明白，请教大家，一共8处。可能是多了点，麻烦各位NN们帮助解答一下谢谢了。

1.Nathaniel Hawthorne often complained of how few material his life provided for his fiction. 2.Physical fitness activities can lead to an alarming variety of injures if participants push themselves greatly hard. 3.Xanthines have both good and bad effects on the body, these effects are generally determined on the size and regularity of dosage. 4.In 1977, Marily Yadlowski, a undergraduate at Cornell University, found that pigeons had excellent low frequency hearing, far surpassing that of humans.（比较Abraham Lincoln's boyhood home resembled those of many others midwestern pioneers, with its dirt floor, sleeping loft, and crude fireplace.答案是没有问题的，但是比较一下另外的那句，发现这里的those是指代boyhood这个单数名词，those of many others midwestern pioneers和that of humans是不是也错了，还是我理解错误.) 5.Snakes are capable of graceful motion throughout the entire long of their rubbery bodies.这里的entire long是什么意思?答案认为这个是对的。 6.all 和all of有什么区别啊？还有most 和most of的区别？能给举几个例子吗？ 7.The orbit of a celestial body is usually in the shape of ellipse. 8.The Texas Legislature selected Vassar Miller in 1982, and again in 1988. a) was the state's port laureate b) as the state's port laureate c)the state's port laureate d) became the state's port laureate 我查了字典select的用法是select sb/sth (as sth)，请问是否有select sb sth 的用法？

1, 应该是few materials 或者little material 2, greatly 和hard重复，push需要接一个副词，而greatly hard 的结构里，hard是一个形容词。去掉greatly，hard就是一个副词了。 ３，到底是哪个地方错了啊？　

3.我也觉得很奇怪，是不是regularity前面少了个冠词the?还有就是all 和all of ；most 和most of考的好像满多的，还不太明白又什么区别。

有道理，估计是少个the.

关于all与all of的区别就是：all单用的时候，是形容词，意思是“所有的。。。。”；而all of里的all是代词，意思是“。。。。中的所有”。举例如下：All the people are dead. All of the them are happy because of the earned money. most与most of也是这个道理。　 一家之言，仅供参考，：）
