关于sat语法的3个问题,见说明~
1.Langston Hughes may be best known for his peotry,but included among his many published works are a sizable collection of short stories.
求捋下句子结构~谢谢那个included among 觉得特不顺
2.after后面是不能接完成时吗?.after they had swam .为什么不对?
3.Some scientists believe that mentally stimulating activities may increase the munber of btain cellls (available to replace if any) are lost through aging.为什么括号里的部分要改成availableto replace any that?
THANK U AND WISH WHO EVER HELPED ME OUT GOOD LUCK!

Answer 1

1.这句句是一个并列句,用 “but ” 来连接表示意义有转折.
but ……… 是一句倒装句,相当于下面这句：
but a sizable collection of short stories are included among his many published works.
由于主语“a sizable collection of short stories ” 太长了,句子用部分倒装,把“included”
放到前面来.
全句的意思大概是：
Langston Hughes 也许是因为诗而出名,然而在他已经出版的大量作品中有相当数量短篇故汇编.
这句话潜台词应该是：Langston 不单是诗写得好,而且还应该是短篇小说家.
2.你字写错了,不应该是“swam”,而是“swum”.
swim swam swum
3.用 avaiable replace any that 连接构成定语从句,修饰 “any”,句子通顺.
一些科学家相信,刺激大脑神经的各种活动会增加大脑细胞数量,这些增加脑细胞可以用来替补人们因年老而失去的那些.
如果用你说的 …… if any 连接,句子不通.
供你参考.
