e的错误是不是主要在she was less successful...和photographer Lotte...两个句子没有连词？在这个选项里的两个比较对象似乎没问题吧？in Germany不能比表示在德国时的状态么？

我也觉得这是果因 helr大神呀 像这道题 果因和相关因果怎么区分呀

找到一个解释：it is possible that there were 20 days in 1910 with over 2 inches of rainfall, but 15 days in 1990 with much more rainfall each per day. There is no upper limit, so picking numbers should unlock this concept nicely: if 1910 had 20 days at 2.5 inches/day, and 1990 had 15 days at 5 inches/day, then more rain would still fall in 1990 (75 inches vs 50 inches, just like my recent television purchase debate) even though there were fewer days . This may seem improbable, but it is not impossible.

如果选择C，这句话就翻译成：煤不仅是化石燃料和建筑材料的来源，而且是生产钢铁的原材料的来源。
如果选择B，翻译成：除了化石燃料和建筑材料，煤也是生产钢铁的原材料的来源。

这个没有理解啊？煤为什么会是这3个的来源？

名词与从句区别／不定式与从句／核心词
用之于本题，由于研究揭示的内容在本题中可以被认为是“事实”，而事实没有时间终止点，应该用宾语从句。（跟evidence一样）

不定式
instead of 是介词短语，后面应加名词（短语），代词，宾语从句（用动名词形式,即Ving）等；而rather than 是个连词，前后成分在形式上必须保持一致。

n^3-n=n（n-1）（n+1）
（1）n=2k+1，说明n为奇数。那么n（n-1）（n+1）则为奇偶偶，里面至少含有2个2，所以可以被4整除

平行

swimming the distance almost two hours faster than

Eliminate as 'which' is used incorrectly here. 'Which' always modifies the nearest grammatically eligible word.
a选项中并列的时态有问题

考点：代词／平行

grow已经表达了“长大”的概念，不用再加介词up to，只需用to即可。
as high as和in height是赘余的,第一个as为副词,第二个as为连词.

过去分词短语recovered by archaeologists in 1982是they found more than 17,000 artifacts on board的伴随状语。
从句是finding more than 17,000 artifacts on board，如果是定从，那做主语的who应该是不能省略的吧？所以应该是伴随，伴随的话逻辑主语就错了

核心词错误
because of the size increase being slight for males for females it was great的核心词为size increase

考点：代词／平行／比较

看来在做画线部分很长的题时，提炼主干，分清主语最重要。

考点：逻辑并列

考点：代词

all the other planets身前是否加of对于本题影响不大，加上或者不加均可。

错了。
不定式和分词中添加的have不是完成时，而是先时性。
evidence身后通常都是用同位语从句的，这个原因就是名词和从句的区别。evidence for exploration，explore在本选项中是一个事实，没有时间终止点。
