Unit 5 Canada-“The True North” 知识总结重、难点解析1. The idea that they would cross the whole continent was exciting. (Reading)(1) 句中that they would cross the whole continent是the idea的同位语从句。一些名词如idea, opinion, view, news, information, message, advice, suggestion, plan, order, promise等，后面可以跟that引导的同位语从句，用来说明其内容。如：All of us were pleased at the news that the Chinese team took second place in the 28th Olympics.中国代表团在第28届奥运会上获第二名的消息让我们感到非常高兴。All of us agreed with her plan that we would have a picnic next weekend.我们大家都赞成她的那项计划：下个周末我们将去野餐。(2) that引导同位语从句和定语从句是有区别的：that引导同位语从句时仅起连接作用，不充当任何成分，也无意义，但不能省略，也不能用which替代；that引导定语从句时，要充当一定的句子成分（主语、宾语、表语），作宾语时可以省略，指物时可用which替代。请比较下面两个句子：The news that our team had won soon spread all over the country.（that在句中不作成分，也无意义，它引导的是同位语从句，说明the news的内容）The idea that you came up with at the meeting is wrong.（that在从句中作came up with的宾语，它引导的是定语从句，修饰the idea）2. They went through a wheat-growing province and saw farms that were thousands of square kilometres in size. (Reading)句中in size表示“（面积等的）大小”，类似的短语还有：in height(高度), in area(面积), in weight(重量), in length(长度), in depth(深度)等，这类短语可转换为the size / height / area / weight / length / depth of .结构。如：The well in our school is more than 100 metres in depth.= The depth of the well in our school is more than 100 metres.我们学校的那口井有一百多米深。An elephant may be about one or two tons in weight.= The weight of an elephant may be about one or two tons.一头大象的重量可能有一两吨。考点聚焦 真题再现1. What do you expect to see there? (Pre-reading)考点 expect 意为“希望；预计；认为，料想”， 后可跟名词或不定式等。真题再现1 According to the art dealer, the painting _ to go for at least a million dollars. (2020全国卷 II)A. is expected B. expectsC. expected D. is expecting点拨选A。the painting与expect 之间是被动关系， 故应用被动语态。真题再现2 I arrived late; I _ the road to be so icy. (北京2020春)A. wouldnt expect B. havent expectedC. hadnt expected D. wasnt expecting点拨 选C。句意为“我来晚了，（因为）我没预料到路会这么滑。” “我来晚了”发生在过去，“没预料到”是在“我来晚了”之前，故用过去完成时。2. Its too bad you cant go as far as Ottawa, Canadas capital. (Using Language)考点 as far as 在此意为“远到，直到”，否定句中也可用so far as。另外as far as还常与动词know, see等连用，意为“就所知”等，此时，as far as与so far as可以互换。如：We didnt go as(so)far as the post office.我们并未走到邮局那么远。As (So) far as I know, they are very kind.据我所知，他们很善良。真题再现1How far apart do they live?_ I know, they live in the same neighbourhood. (上海 2020)A. As long as B. As far asC. As well as D. As often as点拨 选B。句意为“据我所知，他们住在同一个居民区里。”真题再现2 _ I can see, there is only one possible way to keep away from the danger. (北京2020春)A. As long as B. As far asC. Just as D. Even if点拨选B。句意为“在我看来，只有一种可能的办法来远离危险。”名词性从句精练精析在第3、4、5单元我们分别学习了宾语从句、表语从句、主语从句和同位语从句。它们都属于名词性从句。下面是我们精选的2020年高考试题中考查名词性从句的试题。赶快来做一做，检查一下自己的学习效果。1.

B。考查表语从句。disagree是不及物动词，从句中不缺宾语，故首先可排除C；由句意“这就是我不同意的地方。”可知应选B。2. A。考查宾语从句。由句意“路上都是雪，我不明白他们为什么还坚持要骑摩托车去。”可知应选A。3. A。考查宾语从句。宾语从句在句中作介词in 的宾语，从句中缺少主语。而在名词性从句中 what可作主语、宾语、表语等；which多作定语；that一般不充当成分；where作状语或表语，故选A。4. B。考查主语从句。从句中动词do缺少宾语，故选what，what引导的从句在句中作主语。5. B。考查同位语从句。that引导的从句是promise的同位语，说明其内容。6. D。考查同位语从句。空格后的句子成分完整，说明的是a story的内容，故用that来引导，作a story的同位语。因同位语从句较长，放在了谓语之后，避免句子显得头重
