alone和lonely有什么区别?
一、alone 形容词,副词,意为“独自的(地)、单独的(地)”,指客观情况(独自一人,没有同伴或助手)
1.alone用作形容词时,一般与be动词连用,在句中作表语.例如:
I am alone at home.(我独自一人在家.)
2.alone作副词,可修饰动词作状语;也可修饰名词或代词作定语
I like to work alone.(我喜欢独自一人工作.状语,修饰动词work)
He alone was in the secret.(只有他一人知道内情.定语,修饰代词He)
二、lonely只用作形容词,在句中既可作定语,也可作表语,表示“孤独的,寂寞的”意思.强调内心孤独,带有浓厚的感情色彩,具有“渴望得到同伴”的含义,其比较级形式为lonelier.
1.lonely用作定语时,意为“孤单的,无伴侣的,无人烟的,荒凉的,偏僻的”等.例如:
I'm a lonely man.(我很孤独,强调内心孤独)
2.lonely 用作表语时,可以表示“孤寂的,寂寞的”意思.例如:
I was alone but I didn”t feel lonely.(我独自一人,但我并不感到孤独.)
when和while的用法和区别
1.when指某个时间点,表示瞬间动作;while 指某个时间段,表示延续性动作.如:
When I got there, she was playing the violin.我到那里时,她正在拉小提琴.
While I was playing the violin, he came to see me.我正在拉小提琴时,他来看我了.
补给站:英语中,延续性动作是由延续性动词发出的,瞬间性动作是由非延续性动词发出的.延续性动词和非延续性动词的区别:
延续性动词是指该动作可以延续一段时间,而不是瞬间结束,如work(工作)、study(学习)、eat(吃)、watch(观看);非延续性动词是指该动作极为短暂,瞬间便会结束,如start(开始)、begin(开始)、hit(撞)、see(看见)、knock(敲)、jump(跳).
2.when和while 还可作并列连词。when表示“在那时”;while表示“而,却”,表对照关系。如:
a. The children were running to move the bag of rice when they heard the sound of a motor bike. 孩子们正要跑过去搬开那袋米,这时他们听到了摩托车的声音。
b. He is strong while his brother is weak. 他长得很结实,而他弟弟却很瘦弱。
3. when用于表示“一……就……”的句型中(指过去的事情).
sb.had hardly(=scarcely) done sth.when...=Hardly / Scarcely had sb.done sth.when...
①I had hardly /scarcely closed my eyes when someone knocked at the door.=Hardly / Scarcely had I closed my eyes when someone knocked at the door.我刚一闭上眼,就有人在敲门了.
②I had hardly /scarcely entered my room when the telephone rang.=Hardly /Scarcely had I entered my room when the telephone rang.我刚一走进房门,电话就响了.
4. 表“正打算做某事突然……”,用be about to do…when…这一句型
I was about to get out the room when the door was opened .我正打算走出这房间突然门就被打开了.
if 条件状语从句中虚拟语气的判断
if 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句,反之为非真实条件句,要用虚拟语气。其形式分为以下三种:
(1) 与过去事实相反的假设。结构为:从句的谓语动词用“had + 过去分词”,主句用“should (would, could, might) + have + 过去分词”。例如:
If it had not rained so hard yesterday, we could have played tennis. 如果昨天没有下大雨,我们就能玩网球了。
(2) 与现在事实相反的假设。结构为:从句的谓语动词用过去式,系动词用were,主句的谓语用“should (would, could, might) + 动词原形”。例如:
If I were in your position, I would marry her. 如果我是你,我就娶她为妻。
(3) 与将来事实相反的假设。结构为:从句的谓语动词用“should (were to) + 动词原形”,主句用“should (would, could, might) + 动词原形”。 例如:
If you should miss the chance, you would feel sorry for it. 如果你错过了这次机会,你会难过的。
