3. The televison show Soul Train reached the height of its popularity in the 1970s and 1980s, （it was showcasing） the latest songs by ……
为什么用showcasing， 还有其它选项：when it showcases
sorry 第二个题正确答案是：C

Answer 1

as they had previously thought（方式状语从句，as 不做成分：意为：像他们之前想的那样）；
basin that they used to think （that引导定语从句，但从句中并不缺少主语或宾语，故不成立）；
B. A structure large enough to be seen from outer space and created by workers moving massive stone blocks is China's Great Wall,( it) spans thousands of miles.（it 改which）；
C. created by workers moving massive stone blocks, China's Great Wall spans thousands of miles, （was created by workers moving masssive stone blocks.缺少主语）
E spanning thousands of miles and it is large enough to be seen from outer space, workers moved massive stone blocks to creat China's Great Wall.（逻辑主语成了 workers）
showcasing ...，分词短语，做伴随状况。

追问

额 我刚才说错了 第二题答案选C，而且第一个啥意思，再讲讲？？

追答

第二题的答案肯定是 D
你问第一题翻译？

追问

但是第二题的答案上写的就是C，而且这是真题，而且我选的是D，所以没看清就打错了， 第一题不是翻译，就是在讲细致一些（that引导定语从句，但从句中并不缺少主语或宾语，故不成立）？？？为什么

但是第二题的答案上写的就是C，而且这是真题，而且我选的是D，所以没看清就打错了， 第一题不是翻译，就是在讲细致一些（that引导定语从句，但从句中并不缺少主语或宾语，故不成立）？？？为什么

追答

that引导定语从句时，通常在从句中充当主语或宾语，并指代先行词，这句话中，think 是不可以直接加名词或代词作宾语的，故判断它错。
再次肯定：第二题是 D是正确的答案

追问

真题答案不会有错的吧~~是官方印的答案，额……要是选D我就不用问了我也选的D

追答

C 答案中 created by workers moving massive stone block 出现两次，怎么解释？
您将题目抄错了？

追问

额 应该是Created by workers moving massive stone blocks, China's Great Wall spans thousands of miles and is large enough to be seen from outer space.

追答

这样 C 就是个正确的句子了。

D. China's Great Wall, a structure large enough to be seen from outer space, spans thousands of miles, （and） was created by workers moving massive stone blocks.
对不起，前面我看错了，加 and 后形成并列句，句子主干为：
China's Great Wall spans thousands of miles, （and） was created by workers moving massive stone blocks. 没有连词 and 连接则不成句,第二并列分句中省去了主语 it/ China's Great Wall。

Answer 2

我来回答第三问，前句是过去时态，说在这时候到达了顶峰。但是，如果用when it showcases则是一般现在时，显然不合逻辑。用过去进行时可以表示表示在过去某一时刻或某一段时间内进行或发生的动作。这样一来，就没什么错误了。
