1、【基础知识巩固】U1T2SA1 get lost 走失，迷路。其中lost为形容词，其近义词有missing和gone。e.g. I found my bike missing.我发现我的自行车丢了。My pen is lost. 我的笔丢了。2 call up给打电话,名词作宾语时可以放在up后面或两词之间；宾语是代词时，必须放在两词之间。e.g. I called Tom up yesterday, but he didnt answer it. 昨天我给汤姆打电话，但他没有接。Ill call you up as soon as I come back. 我一回来就给你打电话。同义词组：

2、ring up, make a telephone call。3 already常用于肯定句中，指动作已经发生,或比期望发生的要早，一般用在句子中间或句末；yet用于疑问句和否定句中，谈论尚未发生但可能发生的事，通常位于句末。e.g. Have you had your lunch yet? 你吃过午饭了吗？Yes, Ive already had it.是的，我已经吃过了。U1T2SB1 population意为“人口”,“居民”，常用形容词large或small来表示人口的多少。e.g. China has the largest population in the world.中国拥有世

5、pulation has caused?你觉得中国的庞大的人口数目引起了什么问题？此句中do you think是插入语，what problems 作cause的宾语,所以do you think之后接陈述句语序。e.g. Who do you know is on duty today? 你知道今天谁值日吗？这里do you know是插入语，who在句中作主语。2 one fifth 五分之一要表示“几分之几的”时，采用“分数+ of+ .”形式。e.g. two thirds of the students 三分之二的学生。英语中分数表示法为：分子采用基数词，分母采用序数词且有单/复数

6、形式。分子大于1，分母要用复数形式。e.g. one seventh七分之一，two sevenths七分之二。注：四分之一亦作a quarter，百分数读作“基数词+percent（无复数）”。e.g. 30%读作thirty percent。half意为“一半，二分之一”，相当于one second或50%。3 because of+n./v.-ing 因为eg. Now most families have only one child because of our countrys one-child policy.=Because our country has the one-ch

7、ild policy, now most families have only one child.由于我国实施独生子女政策，现在大多数家庭只有一个孩子。4 whole着眼于整体，接可数名词单数形式。谓语动词用第三人称单数形式。e.g. The whole family likes watching TV.全家人都喜爱看电视。This whole week has passed quickly.整个一周都过得很快。all着重于全体中的各个部分，接不可数名词或名词复数。e.g. All the people in the ship lost their lives.轮船上所有人都遇难了。5 su

Our country supplies free textbooks to children.=Our country supplies children with free textbooks.我国给孩子们提供免费的教科书。provide, offer与supply意思相近，但用法不同。6 worse and worse 越来越糟糕比较级+an

44、ulation是不可数名词，所以用that代替。如果是复数名词则要用those来代替。3.B 问人口的多少用what而不用how many。本题问的是2019年的人口， 故为过去时态。4.C 分数的表达法是基数词在前表示分子，序数词在后表示分母；当分子大于1时，表示分母的序数词要加s。5.A 本题考查反义疑问句反问部分的时态与人称的单复数要与陈述部分一致的用法。6.C 本题考查increase的现在分词作定语的情况，表示“正在增长的”。increased是它的过去分词也可作定语，但表示的是“已增长过的”。7.A already“已经”，常用于完成时态肯定句中；yet“已经”，常用于完成时态的疑

45、问句和否定句中；still“仍，还”；once“一旦”根据题意选择A。8.B 此题考查不及物动词happen和take place的用法, 不及物动词不能用于被动语态。根据题中changes是复数，答句用完成时态。故选B。9.C in order to和because of后面不能接从句，unless不符合题意。故选C，用because。10.C 上句为否定情况，应用neither/nor+助动词+主语，表示“我也未参观过造纸厂”。. 11.C 12.B 13.D 14.G 15.F. 16.D 本句中要用it来作think的形式宾语，真正的宾语是其后的不定式短语，即主语+谓语+it+adj.

46、+to do sth. 的形式。17.C 本句考查agree with sb. 这一结构。18.A 本句中make it known to是较为正式的习惯用语，表示把某事向公布或发表。19.B 根据题意本句是条件状语从句，所以排除时间状语从句引导词C项。unless“除非，如果不”，if不合题意，if not不能引导从句。故选B。20.A 本句考查die of+n. 短语，意思是“死于”，故选A。21.B 本句指法律被通过，动词选用pass，又是被动语态用be+过去分词，故选B。22.B 本句中谓语动词是单数并与上句呈对比关系，所以排除A、C、D，应选B项。23.C 本句考查make sb. do sth. 这一结构。24.C 表示“不再”有两种结构，一种是not any longer/any more，另一种是no longer/more
