Issue: n. an important topic or problem for debate or discussion
an 'issue' is not necessarily a 'problem'

选项A even是副词，不能用作连词；foods have possibility 语义错误；have possibility for doing错误搭配
选项B foods have possibility 语义错误 ;even 错误
选项C so错误，这里没有表示所以的意思， "with" isn't parallel to anything in the other part of the sentence.
选项D 正确
选项E could和possibly意思重复; and和in addition意思重复; "for" isn't parallel to anything in the other part of the sentence.

E: if you say "the last day that they are scheduled to collect", this means that "day" must be a direct object.
this makes no sense, unless the employees are collecting days.
"the time that we were scheduled to meet" is incorrect. the literal reading of this (which is the only reading you care about, by the way) is that you were scheduled to meet the time itself.

这题讨论的是生产者还在购买者，一切与产品本身有关的选项，都直接排除。

animals that 后面是一个定语从句是说animals的所以用exhibit－－－－A和B错误

(E) 未划线部分的and that没有平行的对象;indicate that的that不能省略;for doing表示目的不及to do有效.句子结构: Records from… indicate that… and that..

D ① harness 约束力较强，不定式to do ；② excited不是完整的谓语动词（缺be动词），无法和predicted并列

6到飞起

天啦噜，这脑子得转的嗖嗖快吧

可以通过CDE 里overcompensating后无and, 没法和未划线部分的growing连接 秒排

their numbers 与and thus后的our variation平行。也只有这一个选项平行

its path也可以指cloud，不是指代storm

哦怪不得一个叫直接论元一个叫核心词论元，真希望SC大部分是这类题。。。

usher vt. 引导；引领
The secretary ushered me into his office.
秘书把我领进他的办公室。

为啥不选E:我觉得列举gum 的功能---bacterial infections 是为了说明前面的那句Confusion also persists surrounding the term “resin,” 。
是为了前面的观点服务的呀

错选E
细节题-Resin is often confused with gum, （a substance produced in plants in response to bacterial infections, ）and with sap, （an aqueous solution transported through certain plant tissues.）
这个题错完全是因为读的太快没仔细看句子结构；主干是Resin is often confused with gum and with Sap.括号里的都是同位语从句；所以细节是说gum，是a substance produced in plants in response to bacterial infections，所以妥妥A

As不是可以表示让步吗

不同意，为什么总量=人均X人数？即然有高科技在，那么也可以是总量=机器平均X机器数

than作为比较结构，主从句的主语谓语都是 babies born to women所以全部省略

没看懂，求讲解
