Polio, although it is eradicated in the United States, it continues elsewhere and is able to be brought into the country by visitors.
Polio, although it is eradicated in the United States, it continues elsewhere and is able to be
Polio, although eradicated in the United States, it still continues elsewhere and can be
Although still continuing elsewhere, polio has been eradicated in the United States and could be
Although having been eradicated in the United States, polio still continues elsewhere and is capable of being

改为 evidence proved… 或evidence that have been proved…
2) be able to do和can的区别: 前者表示拥有某种能力去做某事,强调的是能力;后者表示可能去做
某事,表现了一种可能性
(A) be able to do不合适; it continues中的it多余,因为去掉插入语although后,句子变为Polio it continues…,it和Polio重复
(B) it多余
(C) 随意替换Although的内容, 更改了原句的意思
(D) having been eradicated使用错误,应该去掉having been; is capable of being表示拥有某种能
力,用在此处不合适
(E) 正确, 整个句子简洁,表达清晰,用could表达一种可能性
D: D应该是错在be capable of,be capable of doing sth表示有能力、有才能。
小儿麻痹症有能力被带进美国?错,是可以被带进美国
GMAT里,当be capable of doing sth,have the capability of doing sth和can/could在选项里同时存在时,通常can/could是更优的。

C主从句逻辑有误,应该是虽然P被根除,但是P还是有可能白带进美国
D 虽然P一直正在被根除,但是P仍然还在其他地方继续并且有能力被游客带进美国,
E虽然P被根除,但是P还在其他地方继续并且可能被游客带进美国
C、句意变换
D、redundancy
D中having been eradicated 相较E wordy;is capable of being 病症不能主动拥有能力
确性, 如果主干正确,再来看插入语的正确与否.
(c)(d)比較,is capable of doing sth 後面不會接被動式。(d) eliminated
(c)(e)比較,主從句的關係對調,改變句義,(c) eliminated
GMAT里,当be capable of doing sth,have the capability of doing sth和can/could在选项里同时存在时,通常can/could是更优的。
D,be capable of doing通常修饰无生命物体,也可以指修饰有生命,表示有能力做某事。able/capable/enable都不能接被动式,不能有能力被如何如何;can 可以接被动式
D:be capable通常修饰人
GMAT里,当be capable of doing sth,have the capability of doing sth和can/could在选项里同时存在时,通常can/could是更优的。
"still continues" is a redundant construction; that's a clear error.
Polio 和后面的it 重复了,有两个主语登录 或 注册 后可以参加讨论
1. 状语从句的逻辑主语等于句子主语;
2. 从句的谓语动词是必须是be。
(没要求主句的谓语动词必须是be;换句话来说,状从的省略可以看成是省略了be,且从句主语和谓语be要么同省要么同留。)
