the decline in sales of。。

so。。。。that

Intend to do 的固定搭配，发出者必须是人
所以rule is intended to
"rules intending..." is incorrect, since the rules aren't intending to do anything. rules don't have intentions, although their authors do.
this is a passive type construction. the rules are intended to do x, y, and z, so you need "intended", not "intending".

namely是副词，不能连接两个主句：
namely that 从句

这道题不看省略, 而是毕老师说的, or, but, and的parallel是成分parallel, E的前后都是名词成分的parallel, 所以是对的.

句末代词split没有看到所以错选a

- if n is not divisible by 2, then n is odd, so both (n - 1) and (n + 1) are even. so the product (n - 1)(n + 1) contains one multiple of 2 and one multiple of 4, so it contains at least 2 x 2 x 2 = three 2's in its prime factorization.
- if n is not divisible by 3, then exactly one of (n - 1) and (n + 1) is divisible by 3contains a 3 in its prime factorization.
- thus, the overall prime factorization of (n - 1)(n + 1) contains three 2's and a 3.

E当中what it did错误，the growth of the global economy就是个名词，它没有did sth～

proportion比较，用it/that。 而不是they /those；同类不同体，用that

主句“遵守”是否发生不影响laws的定语requiring xxxx，所以不用不定式。句子的名物化是之前没碰到过的点，需要关注。

Ron说，E错在两点，第一：时态不对，过去完成时表示leaching是过去的办法，现在不用了，但句中并没有表述这种意识； 第二，well established不应该作为非必要修饰语，个人理解从这个句意出发，前半句说这个方法好，后半句说发现这个方法的缺点，well established作为非必要修饰语，就削弱了整个句子的转折意味。

you can only say "X results in Y" when X is an ACTION. if X is an OBJECT, you can NEVER say that X "results" in anything.
this kills choices (c) and (d), in which "stinger" is the subject of the verb "results".

evaluate题，把whether换成yes/no再进行判断

目标：boost its profits

目标：boost its profits

endure是忍耐的意思，若e就是被忍耐了

错选C，在这里but only one的修饰关系是不清楚的，Theorems/Mathematicians

个人感觉，一方面，应该是a reliable supply of water和good growing conditions并列。the combination of 后面肯定有两个事物A和B，如果water和good growing conditions并列，那么，the combination of 后面就只有一个事物 a reliable supply，这样讲不通；另外a reliable supply of conditions逻辑上也似乎讲不通。 另一方面，就of。。。and结构而言，sth of A and B没问题，但sth of A and of B 似乎说不通，而用sth of A and that/those of B可能更合适

(E) contains an unidiomatic “found X as Y” rather than“ found X to be Y”.
另外，原句中有but的转折关系，在E中丢了，还是要注意一下的（虽然我觉得好像并不存在转折关系……）

choice ABC:作为状语的 介词宾语结构中的核心词都是possibility。导致语意出现了变化：除了可能性，叶子还能减少心脏病和中风的危险
choice D,也是介词宾语结构作状语， possible 做形容词修饰动名词 preventing,inhibiting 。但问题出在of some forms of cancer，语意是某些形式的癌症所拥有的预防和抑制
