如果表示“任何,无论哪个”时,any可用在肯定句中.

below、under都表示“在…下面”,below指位置低于某物或在某物的下方,但不一定在某物的正下方,其反义词是above,而under指在某物的正下方,有垂直在下的意思,其反义词是over.
2. by & on & over & through

[正] They’re talking by radio.
“通过无线电交谈”习惯上说talk by radio,名词前不加冠词.
“通过收音机听到”习惯上说hear sth. on/over/through the radio,名词前加冠词.
“通过电视看到”习惯上说watch sth. on TV.
“通过电话交谈”习惯上说talk with sb. on/over the telephone.

4. in the end & at the end of & by the end of & at last
都有“最后”的意思,但in the end表示“结果,末了”,与at last是同义词组,at the end of表示“在……末端,尽头”,后面要接名词短语,by the end of表示“在……结束时,末了为止”,后面接时间短语.
5. to & for & toward(s)
[误] He is leaving to HongKong next month.
[正] He is leaving for HongKong next month.
to,toward(s)作静态介词,表示静态位置时,均表示“朝……”或“向……”,一般两者可通用,towards指时间“将近”,意思是 nearly；to则表示一段时间的终点,“差……到”的意思；for常用在leave、start等后面,表示要去的目的地,不可用to.

[误] Because he was ill, so he didn’t go to school today.
[正] Because he was ill, he didn’t go to school today.
[正] He didn’t go to school today because he was ill.
because通常表示说话人认为这种理由或原因是正式的理由.在含because的句子中,全句强调的重点在原因上,不在主句的结果上.因此,回答why提出的问题时,只能用because,不能用since、as或for.because of后面只能跟短语,不能跟从句.
since表示的原因,指人们已知的事实,常译为“既然”,引导的从句只是一种附带的说明原因,不是对原因的强调.because与since不能与so连用.
as表示原因与since差别不大,只是语气更弱,是显而易见的理由.
for表示因果关系时,可与because替换使用,所不同的只是它只能放在主句之后,不能放在句首.在含for的句子里,for从句有时只是对主句补充说明理由或推断原因,与前一分句不存在因果关系.
2.either…or… & neither…nor… & not only…but also… & both…and…
[误] Either he or I are right.
[正] Either he or I am right.
前三个连词连接名词、代词等作主语时,谓语动词要与离其最近的主语的单复数一致,both…and…的谓语动词则要用复数.

[正] He came here three hours ago.
[正] He has been here for three hours.
come是瞬间动词,不是延续性动词,在肯定句中不能与表示一段时间的状语连用.而要与表示一段时间的状语连用,就要用延续动词.

4. no & not
no意思是“没有”,可以否定一切名词,修饰不可数名词和可数名词的复数时等于not any,修饰可数名词单数时等于not a/an；如果被修饰的名词通常情况下只有一个,则用它的单数形式；不能用a、the、all、every等限制词之前,而not可以.
not意思是“不,不是”,可以否定一切动词,修饰动词.
no more than意思是“不过,仅仅”,相当于only,修饰“数量”词,强调“少”的含义；not more than意思是“至多,不多于,不超过”,用于陈述事实；no more…than和not more…than多用于多音节形容词的比较级.
5. already & yet & still
[误] When we arrived at the airport, the plane had taken off yet.
[正] When we arrived at the airport, the plane had taken off already.
[正] When we arrived at the airport, the plane had already taken off.
already意思是“已经”,一般用于肯定句,常与完成时连用,常用于句中；yet意思是“已经,还”,一般用于否定句和疑问句,常用于句末；still意思是“仍然,还是”,强调动作在进行,主要用于肯定句,常用于句中.
6. also & too & either & so & neither & nor
[误] My parents didn’t like swimming, nor did his.
[正] My parents didn’t like swimming, neither did his.
also用于肯定句,一般放在行为动词之前、助动词、情态动词、系动词之后,too一般用于肯定句末,前面常用逗号；either一般用于否定句末,前面也用逗号；so置于句首,引起句子倒装,表示前面所讲的情况也适用于另一个人或物,具有否定的意思；so后的主语与前一句主语是同一个人或物时,后面的主谓不倒装,表示“确实如此”；neither置于句首,引起句子倒装,表示前面所讲的情况不适用于另一个人或物,具有否定的意思；nor常与 not连用,表示“也不”,neither和nor都可用来对前面的否定陈述加以补充,如果补充的成分否定的不是同一事物,同一内容,就只能用nor,不可用neither；当否定的并列分句有两个以上时,只能用nor,因为neither只能指两者中的一个,nor指三个以上的另一个.
7. sometimes & sometime & some time & some times
[误] You can only keep the book for sometime.
[正] You can only keep the book for some time.
sometimes是频度副词,意思是“有时,不时”,常与一般现在时或一般过去时连用；sometime是副词,意思是“在某个不确定的时间,在某个时候,某时”,可与将来时或过去时连用；some time是名词词组,意思是“一段时间”,做时间状语,也可用作副词词组,用来指一个未肯定的时刻,常指将来,此时可与sometime通用；some times是名词词组,意思是“几次,几倍”.
四、容易混淆的介词：
[考试说明] 熟练掌握介词in、on、at、to、from、by、with、for、about、before的常见用法；理解这11个介词的其他用法及所学其他介词的一般用法.
1. above & over; below & under
[误] Our classroom is over theirs.
[正] Our classroom is above theirs.
[误] The plane flew above the bridge.
[正] The plane flew over the bridge.
[误] The lights hung above the desk.
[正] The lights hung over the desk.
above、over都表示“在…上面”,且都表示表面不接触的上方,但over指垂直在上,而above则表示位置较高,不一定是正上方.
below、under都表示“在…下面”,below指位置低于某物或在某物的下方,但不一定在某物的正下方,其反义词是above,而under指在某物的正下方,有垂直在下的意思,其反义词是over.
2. by & on & over & through
[误] They’re talking on the radio.
[正] They’re talking by radio.
“通过无线电交谈”习惯上说talk by radio,名词前不加冠词.
“通过收音机听到”习惯上说hear sth. on/over/through the radio,名词前加冠词.
“通过电视看到”习惯上说watch sth. on TV.
“通过电话交谈”习惯上说talk with sb. on/over the telephone.
“通过人造卫星收发电视节目”习惯上说through man-made satellites.
3. in & on & to
[误] Tian wan is to the east of China.
[误] Tian wan is on the east of China.
[正] Tian wan is in the east of China.
表示方位“在……(东西南北)边)时,介词in、on、to有不同的用法.以“在……东部”为例,表示在该地范围之内,用in the east of,表示在该地与某地“相邻”,有接壤之意,用on the east of,表示不在该地范围,且有中间物,用to the east of.
4. in the end & at the end of & by the end of & at last
都有“最后”的意思,但in the end表示“结果,末了”,与at last是同义词组,at the end of表示“在……末端,尽头”,后面要接名词短语,by the end of表示“在……结束时,末了为止”,后面接时间短语.
5. to & for & toward(s)
[误] He is leaving to HongKong next month.
[正] He is leaving for HongKong next month.
to,toward(s)作静态介词,表示静态位置时,均表示“朝……”或“向……”,一般两者可通用,towards指时间“将近”,意思是 nearly；to则表示一段时间的终点,“差……到”的意思；for常用在leave、start等后面,表示要去的目的地,不可用to.
五、容易混淆的连词：
[考试说明] 掌握并列连词(如：and、but、or)和从属连词(如：when、if、that等)的基本用法.
1. because & since & as & for
[误] Because he was ill, so he didn’t go to school today.
[正] Because he was ill, he didn’t go to school today.
[正] He didn’t go to school today because he was ill.
because通常表示说话人认为这种理由或原因是正式的理由.在含because的句子中,全句强调的重点在原因上,不在主句的结果上.因此,回答why提出的问题时,只能用because,不能用since、as或for.because of后面只能跟短语,不能跟从句.
since表示的原因,指人们已知的事实,常译为“既然”,引导的从句只是一种附带的说明原因,不是对原因的强调.because与since不能与so连用.
as表示原因与since差别不大,只是语气更弱,是显而易见的理由.
for表示因果关系时,可与because替换使用,所不同的只是它只能放在主句之后,不能放在句首.在含for的句子里,for从句有时只是对主句补充说明理由或推断原因,与前一分句不存在因果关系.
2.either…or… & neither…nor… & not only…but also… & both…and…
[误] Either he or I are right.
[正] Either he or I am right.
前三个连词连接名词、代词等作主语时,谓语动词要与离其最近的主语的单复数一致,both…and…的谓语动词则要用复数.
六、容易混淆的代词：
[考试说明] 熟练掌握人称代词主格、宾格形式及基本用法,在口语和书面语的表达中正确运用；掌握形容词性物主代词和名词性物主代词的基本用法；掌握反身代词作为宾语和同位语的基本用法；熟练掌握指示代词和疑问代词的基本用法.
1. either & each & none & neither & both & all & some
[误] Either of the books are good.
[正] Either of the books is good.
either/ each / none / neither of+复数名词或代词作主语时,谓语动词用单数, 其中neither的也可用复数；both/ all /some of+复数名词或代词作主语时,谓语动词用复数
