考点名称：一般现在时，动词单数第三人称
一般现在时： 表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。可概括为 ①经常性或习惯性动作； ②长期存在的特征或状态； ③普遍真理、客观事实等。 构成： 一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。 a. 表示经常性或习惯性的动作。 例：Li Ming always helps the old man. 李明一直帮助这位老人。 We usually go to school on foot. 我们通常步行上学。 They sometimes go fishing on Sundays. 他们有时周日去钓鱼。 b. 表示永恒不变的事实或真理。 例：A bird flies with wings. 鸟用翅膀飞翔。 c. 用在格言、谚语中。 例：Pride goes before a fall. 骄者必败。
一般现在时具体用法: 1.表示经常的或习惯性的动作，常与表示频率的时间状语连用。 时间状语： always，usually，every morning/night/evening/day/week/year，often，sometimes， occasionally，from time to time，twice a week，rarely,seldom，once a month，hardly，ever,never. e.g： I leave home for school at 7:00 every morning.
2.表示主语具备的性格、能力、特征和状态。 e.g：I don't want so much. Ann Wang writes good English but does not speak well. 比较：Now I put the sugar in the cup. I am doing my homework now.
3.表示客观事实和普遍真理。 e.g ：The earth moves around the sun. Shanghai lives in the east of China.
9表示格言或警句中。 e.g Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round.. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。 再如：Now watch me,I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。
一般现在时的特殊用法: 一些动词可用一般现在时来表达现在进行时： verbs of the senses: hear,see,taste,smell，feel verbs of the thinking: believe,know,mean,realize,think,remember verbs of the linking: dislike,fear,heat,like,love,want verbs of the possession: belong,have,own,possess
考点名称：动词不定式
不定式定义： 由to+动词原形构成。不定式是一种非限定性动词。而非限定动词是指那些在句中不能单独充当谓语的动词，可分为不定式，动名词，现在分词和过去分词。 “动词不定式”由动词+不定式构成。动词不定式在句中可以作句子除谓语之外的任何句子成分。动词不定式的被动形式除了一般形式外还有其完成式和进行式。 常见的有：like / love，want，need，ask，help等。 例：I like to play with Tom. 我喜欢和汤姆玩。 I want to play with Tom. 我想和汤姆玩。 I like to eat dumplings. 我喜欢吃饺子。
动词不定式一般结构: 疑问词who,what,which,when,where,whether,how后可接不定式构成不定式短语，在句中作主语、宾语、表 语等。如： ①When to leave for London has not been decided yet. （不定式在句子中做主语） ②Mr. Smith didn't know whether to leave or stay there. （不定式在句子中做宾语） ③I asked Professor Xu how to learn English well. （不定式在句子中做直接宾语） ④The question was where to get the medicine needed. （不定式在句子中表语） 以上例句中疑问词+不定式部分，均可转换为相应的从句形式。如： ①When we shall leave… ③…how I could learn… 经常在这种结构中使用的动词有： consider,decide,discover,explain,find out,forget,hear,know,lea rn,observe,understand,wonder等。
3在下列情况下，一般要用不定式： ①hate,like,love前有would(should)时， 如：I'd like to have a cup of coffee. ②当谓语动词begin,continue,start等是进行式时， 如：Thestudents are starting to work on the di fficult maths problem. ③begin,continue,start与know,understand等状态动词连用时， 如：I soon began to understand what was happening. ④.advise,allow,encourage,forbid,permit等动词后接动名词作宾语，或带不定式作宾语补足语。如： Our teachers don't permit our/us swimming in the lake. Our teachers don't permit us to swim in the lake.
4 部分动词后接不定式或动名词时，意义差别较大，应根据句子语境选择使用。 forget,remember,regret后接不定式，表示现在或未来的动作，接动名词表示动作已经发生。如： Don't forget to post the letter for me. Have you forgotten meeting her in Beijing Airport? Remember to close the windows before you leave. I remember writing him a letter a year ago. We regret to tell you that all of you are not invited toattend the meeting. They regretted ordering these books from abroad.
省to的动词不定式: （1）情态动词( 除ought 外，ought to意思是“应该”，是情态动词，只有一种形式，后边接动词不定式，to不能省略。 ought to没有人称和数的变化，后接动词原形可以表示现在、将来或过去将来，由时间状语或上下文决定。例如： They ought to come tomorrow.他们明天应当来)： （2）使役动词 let,have,make： （3）感官动词see,watch,look at,notice,observe,hear,listen to,smell,feel,find 等后作宾补，省略to。 注意：在被动语态中则to 不能省掉。 在使役动词中get除外(get sb. to do sth.) I saw him dance. =He was seen to dance. The boss made them work the whole night. =They were made to work the whole night. （4）表示个人意愿或倾向的would rather，had better，might(just) as well：rather than置于句首时。 Rather than ride on a crowded bus,he always prefers to ride a bike. （5）Why… / why not…： （6）help 可带to，也可不带to,help sb (to) do sth： （7）but和except：but前是动词do时，后面出现的动词用不带to的动词不定式。 （8）由and,or和than连接的两个不定式，第二个to 可以省去： （9）通常在discover,imagine,suppose,think,understand等词后，可以省去to be： He is supposed (to be) nice. 他应该是个好人。 （10）but作介词，后接不定式结构时，前面谓语动词部分若含有do的形式时，but后的不定式要省去to，否则要带to。 He wants to do nothing but go out. He wants to believe anything but to take the medicine. （11）当两个或多个不定时短语由连词and，but或or连接时，后一个或几个不定式符号to常省略。但若表示对比、对照关系时，则不能省略。 He wants to move to France and marry the girl. The purpose of new technologies is to make life easier,not to make it more difficult. （12）不定式做表语时，一般要带to，但若主语部分中含有do的各种形式时，符号to可省去。 We've missed the last bus.All we could do now is walk home.
