知识拓展 1 with复合结构
with复合结构为“with+宾语+宾语补足语”，常在句中作状语，表示伴随、方式、时间、条件或原因等，可位于句首，也可置于句尾。

[解析] 句意为：有许多问题要解决，他感到焦虑。/有许多问题未解决，他感到焦虑。根据句意可知，此处表示有问题需要被解决，表示将来动作，应用不定式的主动形式表被动含义；此处也可表示“未解决的”，用形容词unsolved作many problems的宾语补足语。
知识拓展 2 同位语从句
在复合句中作名词的同位语的从句称为同位语从句。同位语从句一般放在抽象名词（doubt, hope, idea, news, opinion, thought, wish, fact, problem, suggestion, advice, order, message, warning等）的后面，用以解释或说明抽象名词所表示的具体内容。同位语从句的引导词主要分为以下几种：
引 导 词 功 能 例 词
从属连词 只起连接作用，在从句中不作任 何成分。 that, whether
连接代词 既起连接作用，又在从句中作主 语、宾语、定语或表语。 who, what, which, whoever, whatever, whichever
连接副词 既起连接作用，又在从句中作状 语。 how, when, where, why, whenever, wherever, however
I've come from Mr Wang with a message that he won't be able to see you this afternoon.我从王先生那里带了条消息过来，他今天下午不能来看你了。
There is some doubt whether he will come.他是否会来还不一定。
The question who was to blame has never been settled.该由谁负责，这个问题一直没有得到解决。
He had no idea why she left.他丝毫不知道她为什么离开。
特别注意 that引导的同位语从句容易与其引导的定语从句相混淆。应注意当that引导同位语从句时，that在从句中不作任何成分，且不能省略；而当that引导定语从句时，that在从句中作成分，且作主语时不可省略，作宾语或表语时可以省略。
Have you heard the news that our team won the match 你听说我们队赢得比赛的消息了吗？（同位语从句）
The news that he told you wasn't true.他告诉你的那个消息不是真的。（定语从句）
定向练2
一、在空白处填入1个适当的单词。
1.There is no doubt _____ you are bound to have an accident if you drive so fast down the motorway.
that
[解析] “There is no doubt that…”是固定句型，意为“毫无疑问……”，that引导同位语从句。句意为：如果你在高速公路上驾驶得这么快，毫无疑问你会出事故的。
2.[课标全国Ⅰ] While they are rare north of 88°, there is evidence _____ they range all the way across
the Arctic, and as far south as James Bay in Canada.
that
[解析] 分析句子结构可知，设空处引导同位语从句，解释说明evidence的内容，从句不缺成分，且句意完整，故填that。句意为：虽然它们很少出现在北纬88度（的地区），但有证据表明，它们的活动范围遍及北极地区，甚至南至加拿大的詹姆斯湾。
二、根据汉语意思完成句子。
1.我不知道他什么时候会回来。
I have no idea __________________________.
when he will come/be back
