以下是引用Dinaxie在2006-3-19 12:13:00的发言：

the first inhabitants of the territories     Canada came across the Bering Strait and along the edge of the Arctic ice.

C  that make up now       D that now make up   

答案为D，可是C为和不对？两者区别？如果c那就now成形容词了

Alaska became the forty-ninth state in 1959, and Hawaii became the fiftieth state lately that year.

Lately 为何不对，怎么改呢？LATE

Almost every the hereditary material of an individual organism resides in the chromosomes.

A, every 为何不对？作为形容词只能修饰n/adj，怎么改呢？each of?可是没见过every of  ALL

Manipulation of the spinal column, massage, and dietary adjustments        used in chiropractic therapy.

a. the principal methods are    b. are the principal methods

答案为B,主语Manipulation of sth　不是单数吗？这个，我也不知道，但没有 is the principal methods那就很好啦~

还有一些阅读的疑问，可是不知道能发在哪，这里可以通融一下吗？
