必备知识清单
单元语法释疑
一、时间状语从句
(一)定义
在复合句中,由时间连接词引导的表示时间的从句就是时间状语从句。它在句中相当于时间状语,用来修饰主句中的动词、形容词或整个句子,表明动作发生的时间。例如:When I was young, I liked reading fairy tales.(当我小时候,我喜欢读童话故事。)在这个句子中,“When I was young” 就是时间状语从句,说明了 “liked reading fairy tales” 这个动作发生的时间背景。
(二)引导时间状语从句的从属连词及用法
1.when,while,as 引导时间状语从句:这三个词都有 “当…… 时” 的意思,但用法有区别。
①when:既可以表示时间点,也可以表示时间段。从句中的动词既可以是非延续性动词(瞬间动词),也可以是延续性动词。例如:
When she came in, I was doing my homework.(她进来时,我正在做作业。)“came in” 是非延续性动词,强调时间点。
When I lived in the countryside, I often went fishing.(当我住在农村时,我经常去钓鱼。)“lived” 是延续性动词,表示时间段。
②在将来时态中,常用 when 引导从句,且从句须用一般现在时代替将来时。如:
I will tell him the news when he comes back.(他回来时我会告诉他这个消息。)
③while:表示 “当…… 的时候;在…… 期间”,从句的谓语动词必须是延续性动词或表示状态的动词,且通常用进行时。例如:
While my mother was cooking, I was watching TV.(我妈妈做饭的时候,我在看电视。)“was cooking” 和 “was watching” 都是延续性动词的进行时形式,表示两个动作同时进行。
You can't talk loudly while others are working.(别人工作的时候你不能大声说话。)
④as:引导时间状语从句时,从句的谓语动词既可以是延续性的,也可以是非延续性的。当从句中的谓语动词是延续性动词,表示 “当…… 的时候” 时,往往可以与 when 或 while 通用,但 as 更侧重主句与从句的行为同时发生,常译作 “随着……;一边……,一边……”。例如:
As we walked, we talked about our dreams.(我们一边走,一边谈论我们的梦想。)这里强调两个动作同时进行。
As time goes by, we are growing older.(随着时间的流逝,我们渐渐变老。)
2.before 引导时间状语从句:意为 “在…… 之前”。例如:
Don't forget to turn off the lights before you leave the room.(你离开房间之前别忘了关灯。)
I had learned some English before I started to learn French.(我开始学法语之前已经学了一些英语。)
3.after 引导时间状语从句:意为 “在…… 之后”。例如:
I will go for a walk after I finish my homework.(我完成作业之后会去散步。)
After he graduated from university, he found a good job.(他大学毕业后找到了一份好工作。)
为了表明动作的先后,从句中动词可用过去完成时,主句用一般过去时。如:After he had had breakfast, he went to school.(他吃完早饭后去上学了。)
4.until,till 引导时间状语从句:意为 “直到…… 为止”。
①肯定句:在肯定句中,主句的谓语动词必须是延续性动词,表示这个动作一直持续到 until/till 引导的时间点为止。例如:
We waited until/till the rain stopped.(我们一直等到雨停。)“waited” 是延续性动词。
②否定句:在否定句中,主句的谓语动词通常是非延续性动词,表示这个动作直到 until/till 引导的时间点才开始发生,意为 “直到…… 才”。例如:
He didn't go to bed until his mother came back.(直到他妈妈回来他才上床睡觉。)“go to bed” 是非延续性动词。
③till 与 until 的区别:till 和 until 意思相近,很多情况下可以互换。但 until 比 till 稍正式,在正式文体中一般用 until;till 多与名词或较短的从句连用,而较长较复杂的成分多用 until;在句子开头时,用 until 而不用 till。例如:
She stayed here till/until midnight.(她在这里一直待到午夜。)
Until you told me, I had no idea about it.(直到你告诉我,我才知道这件事。)
5.since 引导时间状语从句:意为 “自…… 以来”。
Since I came to this school, I have made many friends.(自从我来到这所学校,我交了很多朋友。)
He has lived in Beijing since he was born.(他自从出生就一直住在北京。)
since 引起的时间状语从句通常用一般过去时态,主句用现在完成时态。这是一个重要的时态搭配规则,要牢记。
二、as soon as 的用法
(一)基本含义
“as soon as” 意为 “一…… 就……”,强调两个动作几乎是紧接着发生的。它引导的是时间状语从句。例如:I will call you as soon as I arrive at the airport.(我一到机场就会给你打电话。)这里 “arrive at the airport” 和 “call you” 两个动作会紧接着发生。
(二)时态运用
1.主句一般将来时,从句用一般现在时代替一般将来时:这是 “as soon as” 引导时间状语从句时非常重要的一个时态规则,也就是我们常说的 “主将从现”。例如:
He will tell his parents the good news as soon as he gets home.(他一到家就会把这个好消息告诉他的父母。)主句 “He will tell his parents the good news” 是一般将来时,从句 “as soon as he gets home” 用一般现在时。
The students will start the experiment as soon as the teacher gives the instruction.(老师一给出指示,学生们就会开始实验。)
2.主句用一般过去时,从句也用一般过去时:指紧接着发生的两个短动作,在描述过去的事情时,主从句都用一般过去时。例如:
She took out her book as soon as she sat down at the desk.(她一在书桌前坐下就拿出了她的书。)“took out” 和 “sat down” 都是过去发生的短动作,所以主从句都用一般过去时。
He turned on the TV as soon as he entered the room last night.(昨晚他一进房间就打开了电视。)
三、现在完成时的时间状语的用法
(一)与不确定时间状语连用
1.already(已经):常用于肯定句,一般位于助动词 have/has 之后,实义动词之前。它强调动作已经完成,对现在有影响。例如:
We have already cleaned our classroom.(我们已经打扫了教室。)意味着教室现在是干净的状态。
She has already finished her homework, so she can watch TV now.(她已经完成了作业,所以现在可以看电视。)体现完成作业这一动作对现在能看电视的影响。
2.yet(已经;还;仍然):用于疑问句或否定句,常位于句末。在疑问句中,表示询问某动作是否已经发生;在否定句中,表示某动作尚未发生。例如:
Have you seen the new movie yet?(你已经看过那部新电影了吗?)期望得到关于是否看过电影的回答。
I haven't eaten breakfast yet.(我还没吃早饭。)说明目前 “没吃早饭” 的状态。
3.just(刚刚):用于肯定句和一般疑问句,位于助动词 have/has 之后,行为动词之前。表示动作刚刚结束不久。例如:
He has just come back from school.(他刚从学校回来。)描述回来这个动作刚完成。
Have you just arrived here?(你刚到这儿吗?)询问到达这个动作是否刚发生。
4.ever(曾经):多用于否定句或疑问句。在疑问句中,询问某人在过去的经历中是否做过某事;在否定句中,强调从未有过某种经历。例如:
Have you ever been to Beijing?(你曾经去过北京吗?)想了解对方过去有无去北京的经历。
I don't think I've ever seen such a beautiful flower before.(我觉得我以前从未见过这么漂亮的花。)突出以前没有这样的经历。
5.never(从不):用于否定句,位于助动词 have/has 之后,行为动词之前。表示从过去到现在都没有发生过某个动作。例如:
She has never traveled by plane.(她从未坐过飞机旅行。)强调一直没有坐飞机旅行的经历。
They have never eaten sushi before.(他们以前从没有吃过寿司。)说明在过去的时间里都没有吃过寿司。
(二)与表示一段时间的状语连用
1.for + 时间段:表示动作从过去开始,持续到现在,可能还会继续持续下去。此时句中的谓语动词必须是延续性动词。例如:
I have lived in this city for ten years.(我在这座城市已经住了十年了。)从十年前开始居住,一直持续到现在,且有可能继续住下去。
He has studied English for three years.(他学英语已经三年了。)三年前开始学习英语,到现在还在学习。
2.since + 时间点:也表示动作从过去某一时刻开始,一直持续到现在。since 后面接的是一个具体的过去时间点,如 since 2010(从 2010 年起),since last week(从上周起)等。同样,句中的谓语动词要用延续性动词。例如:
We have known each other since we were in primary school.(自从我们上小学时就认识彼此了。)从小学那个时间点开始,认识这个状态一直持续到现在。
She has worked in this company since 2015.(她自 2015 年以来就在这家公司工作。)从 2015 年开始工作,一直持续到现在。
3.since + 一般过去时从句:这种结构也是表示从过去某一动作发生时开始,一直持续到现在。从句中的动作是一个过去发生的短暂动作,主句的谓语动词为延续性动词。例如:
I have lived here since I came to this city.(自从我来到这座城市,我就一直住在这里。)“came to this city” 是过去发生的短暂动作,从那时起 “live here” 这个动作一直持续到现在。
He has been ill since he caught a cold last week.(自从上周他感冒后,就一直生病。)“caught a cold” 是过去的短暂动作,之后 “be ill” 的状态持续到现在。
(三)与其他时间状语连用
1.in the past/last + 时间段:意为 “在过去的…… 时间里”,表示从现在往前推一段时间,在这段时间内发生的动作对现在有影响。例如:
In the past few years, we have made great progress in our studies.(在过去的几年里,我们在学习上取得了很大的进步。)强调过去几年的学习情况对现在的影响,现在处于有进步的状态。
She has read many books in the last month.(在上个月里,她读了很多书。)说明上个月读书这个动作对现在知识储备等方面可能产生的影响。
2.so far(到目前为止):表示从过去到现在的一段时间,常与现在完成时连用,强调动作从过去开始一直持续到现在的结果。例如:
So far, we have learned about 1000 English words.(到目前为止,我们已经学了大约 1000 个英语单词。)体现从过去开始学单词,到现在积累的数量。
The project has been going well so far.(到目前为止,这个项目进展顺利。)描述项目从开始到现在的整体情况。
3.recently(最近) /lately(近来):这两个词意思相近,都表示在最近的一段时间内发生的动作对现在有影响。例如:
I have seen her recently.(我最近见过她。)说明最近发生的 “见她” 这个动作对现在有影响,可能现在还记得她的样子等。
He has been very busy lately.(他近来一直很忙。)表明近来这段时间他处于忙碌的状态,这种状态持续到现在。

考查延续性动词和非延续性动词。has gone去了某地;has been去过某地。根据“The boss is wondering where she...and how long she...there.”可知,此处是宾语从句,由where引导,has gone作谓语,意为“去了哪里”,第二空,how long引导,has been作谓语,there作地点状语,意为“待了多久”,故选D。
50.C
【解析】句意:——迈克不在家。你知道他在哪里吗? ——他去了古徽州城。因为工作原因,他已经去过那里三次了。
考查has been to和has gone to的辨析。has been to表示“去过某地(现在已返回)”,强调经历,后可接次数;has gone to表示“去了某地(现在未返回,可能在路上或已到达)”,强调动作的完成。第一空:根据“Mike isn’t at home”可知,他此刻未返回,应用has gone to;第二空:根据“three times”可知,此处强调“去过三次”的经历,应用has been (to),因there为副词,省略to。故选C。
二、
51. Have you been to
【解析】由汉语和所给的英语翻译可知,have/has been to表示“去过某地”,现在已经回来,不在那里了,这里的主语是you,因此助动词用have,此句为一般疑问句,把have提前,首字母大写。故填Have;you;been;to。
52. been many times
【解析】“曾去过”have been to,固定短语;“很多次”many times,故填been;many;times。
53. been dead
【解析】根据中英文对照可知,“去世”未翻译。be dead意为“去世”,表示状态,是延续性的;又因为和for two years一段时间连用,所以要用现在完成时;现在完成时的基本结构为:have/has+过去分词,be的过去分词是been,所以答案是been dead。故填been;dead。
54. put on
【解析】put on“增重”,has与过去分词构成现在完成时结构,put的过去分词还是put,故填put;on。
55. has had
【解析】根据“for more than ten years”可知,用现在完成时has/have done,动词用延续性动词,have“拥有”,主语是第三人称单数。故填has;had。
56. has belonged to
【解析】belong to表示“属于”,是固定短语。根据“since long long ago”可知,本句是现在完成时:have/has done。主语是第三人称单数,助动词用has。故填has;belonged;to。
57. as soon as
【解析】根据中英文提示可知,此处使用as soon as“一……就……”;该短语引导时间状语从句,遵循“主将从现”原则,从句“I set the table”为一般现在时,主句“My mom will start cooking dinner”为一般将来时,符合语法规则。故填as;soon;as。
58. didn’t feel until
【解析】根据中英文提示可知,句子时态为一般过去时,not…until…“直到……才……”,固定搭配;feel“感觉”,动词;时态为一般过去时,对其否定时,应用助动词didn’t。故填didn’t;feel;until。
59. until scored in
【解析】根据中英文对照可知,第一空表示“直到”,until“直到”。第二空表示“得分”,score“得分”,本句是一般过去时,谓语动词用其过去式。第三空需要填入表示“在”的介词,in“在”,in the last minute“在最后一分钟”,为固定搭配。故填until;scored;in。
60. When looked up listened to
【解析】根据中英文对照可知,句中缺少“小时候”、“抬头看”和“听”的英文内容。“小时候”使用“When”,引导时间状语从句;“抬头看”英文表达为“look up”,时态为一般过去时,使用过去式“looked”;“听”为英文表达“listen to”,时态为一般过去时,使用过去式“listened”。故填When;looked;up;listened;to。
61. As she grew older
【解析】随着她长大:As she grew older,表示随着时间的推移某事逐渐发生;句中as引导时间状语从句,放在句首,句首字母要大写。结合“she learned a lot about history.”可知时态为一般过去时,grew是grow的过去式形式,故填As;she;grew;older。
62. arrive in
【解析】到达某地:arrive in,动词短语;as soon as引导时间状语从句,主句是一般将来时,从句用一般现在时,主语为I,动词用原形arrive,故填arrive;in。
63. before he passed away
【解析】根据中英文提示可知,缺少“去世前”,“在……之前”用before表示,“去世”用passed away,此处before引导时间状语从句。故填before;he;passed;away。
64. turn off when
【解析】关掉:turn off,句子是祈使句,以动词原形开头;当:when,引导时间状语从句。故填turn;off;when。
65. going shopping
【解析】根据中英文对照可知,go shopping表示“购物”。此处when引导时间状语从句,从句主语为主句主语we,句子时态为现在进行时,此处可以省略从句主语和be动词,故空格处应填going shopping。故填going;shopping。
66. When join in
【解析】when“当……时”,引导时间状语从句,句首单词首字母应大写;join in“参加”,情态动词“should”后接动词原形join。故填When;join;in。
67. The moment
【解析】根据语境可知,此处表示“一……就……”的时间状语从句;由英语句式结构可知,应使用“the moment”引导时间状语从句。故填The;moment。
68. when I grow up
【解析】对照中英文可知,缺少“长大后”。此句可以用when引导的时间状语从句表示,即“当我长大时”,从句时态为一般现在时,表将来。I“我”,作主语;grow up“长大”,主语为I,动词用原形。故填when;I;grow;up。
69. warming need step by step
【解析】根据中英文对照可知,此处使用warm up表示“热身”,need to do sth表示“需要做某事”,step by step表示“逐步”;在when引导的时间状语从句中,主语与主句主语一致,且含有be动词时,可省略主语和be动词。故填warming;need;step;by;step。

2025-2026学年上学期八年级英语知识点梳理与巩固(北师大版2024)
Unit 6 Celebrations语法知识
必备知识清单
单元语法释疑
一、时间状语从句
(一)定义
在复合句中,由时间连接词引导的表示时间的从句就是时间状语从句。它在句中相当于时间状语,用来修饰主句中的动词、形容词或整个句子,表明动作发生的时间。例如:When I was young, I liked reading fairy tales.(当我小时候,我喜欢读童话故事。)在这个句子中,“When I was young” 就是时间状语从句,说明了 “liked reading fairy tales” 这个动作发生的时间背景。
(二)引导时间状语从句的从属连词及用法
1.when,while,as 引导时间状语从句:这三个词都有 “当…… 时” 的意思,但用法有区别。
①when:既可以表示时间点,也可以表示时间段。从句中的动词既可以是非延续性动词(瞬间动词),也可以是延续性动词。例如:
When she came in, I was doing my homework.(她进来时,我正在做作业。)“came in” 是非延续性动词,强调时间点。
When I lived in the countryside, I often went fishing.(当我住在农村时,我经常去钓鱼。)“lived” 是延续性动词,表示时间段。
②在将来时态中,常用 when 引导从句,且从句须用一般现在时代替将来时。如:
I will tell him the news when he comes back.(他回来时我会告诉他这个消息。)
③while:表示 “当…… 的时候;在…… 期间”,从句的谓语动词必须是延续性动词或表示状态的动词,且通常用进行时。例如:
While my mother was cooking, I was watching TV.(我妈妈做饭的时候,我在看电视。)“was cooking” 和 “was watching” 都是延续性动词的进行时形式,表示两个动作同时进行。
You can't talk loudly while others are working.(别人工作的时候你不能大声说话。)
④as:引导时间状语从句时,从句的谓语动词既可以是延续性的,也可以是非延续性的。当从句中的谓语动词是延续性动词,表示 “当…… 的时候” 时,往往可以与 when 或 while 通用,但 as 更侧重主句与从句的行为同时发生,常译作 “随着……;一边……,一边……”。例如:
As we walked, we talked about our dreams.(我们一边走,一边谈论我们的梦想。)这里强调两个动作同时进行。
As time goes by, we are growing older.(随着时间的流逝,我们渐渐变老。)
2.before 引导时间状语从句:意为 “在…… 之前”。例如:
Don't forget to turn off the lights before you leave the room.(你离开房间之前别忘了关灯。)
I had learned some English before I started to learn French.(我开始学法语之前已经学了一些英语。)
3.after 引导时间状语从句:意为 “在…… 之后”。例如:
I will go for a walk after I finish my homework.(我完成作业之后会去散步。)
After he graduated from university, he found a good job.(他大学毕业后找到了一份好工作。)
为了表明动作的先后,从句中动词可用过去完成时,主句用一般过去时。如:After he had had breakfast, he went to school.(他吃完早饭后去上学了。)
4.until,till 引导时间状语从句:意为 “直到…… 为止”。
①肯定句:在肯定句中,主句的谓语动词必须是延续性动词,表示这个动作一直持续到 until/till 引导的时间点为止。例如:
We waited until/till the rain stopped.(我们一直等到雨停。)“waited” 是延续性动词。
②否定句:在否定句中,主句的谓语动词通常是非延续性动词,表示这个动作直到 until/till 引导的时间点才开始发生,意为 “直到…… 才”。例如:
He didn't go to bed until his mother came back.(直到他妈妈回来他才上床睡觉。)“go to bed” 是非延续性动词。
③till 与 until 的区别:till 和 until 意思相近,很多情况下可以互换。但 until 比 till 稍正式,在正式文体中一般用 until;till 多与名词或较短的从句连用,而较长较复杂的成分多用 until;在句子开头时,用 until 而不用 till。例如:
She stayed here till/until midnight.(她在这里一直待到午夜。)
Until you told me, I had no idea about it.(直到你告诉我,我才知道这件事。)
5.since 引导时间状语从句:意为 “自…… 以来”。
Since I came to this school, I have made many friends.(自从我来到这所学校,我交了很多朋友。)
He has lived in Beijing since he was born.(他自从出生就一直住在北京。)
since 引起的时间状语从句通常用一般过去时态,主句用现在完成时态。这是一个重要的时态搭配规则,要牢记。
二、as soon as 的用法
(一)基本含义
“as soon as” 意为 “一…… 就……”,强调两个动作几乎是紧接着发生的。它引导的是时间状语从句。例如:I will call you as soon as I arrive at the airport.(我一到机场就会给你打电话。)这里 “arrive at the airport” 和 “call you” 两个动作会紧接着发生。
(二)时态运用
1.主句一般将来时,从句用一般现在时代替一般将来时:这是 “as soon as” 引导时间状语从句时非常重要的一个时态规则,也就是我们常说的 “主将从现”。例如:
He will tell his parents the good news as soon as he gets home.(他一到家就会把这个好消息告诉他的父母。)主句 “He will tell his parents the good news” 是一般将来时,从句 “as soon as he gets home” 用一般现在时。
The students will start the experiment as soon as the teacher gives the instruction.(老师一给出指示,学生们就会开始实验。)
2.主句用一般过去时,从句也用一般过去时:指紧接着发生的两个短动作,在描述过去的事情时,主从句都用一般过去时。例如:
She took out her book as soon as she sat down at the desk.(她一在书桌前坐下就拿出了她的书。)“took out” 和 “sat down” 都是过去发生的短动作,所以主从句都用一般过去时。
He turned on the TV as soon as he entered the room last night.(昨晚他一进房间就打开了电视。)
三、现在完成时的时间状语的用法
(一)与不确定时间状语连用
1.already(已经):常用于肯定句,一般位于助动词 have/has 之后,实义动词之前。它强调动作已经完成,对现在有影响。例如:
We have already cleaned our classroom.(我们已经打扫了教室。)意味着教室现在是干净的状态。
She has already finished her homework, so she can watch TV now.(她已经完成了作业,所以现在可以看电视。)体现完成作业这一动作对现在能看电视的影响。
2.yet(已经;还;仍然):用于疑问句或否定句,常位于句末。在疑问句中,表示询问某动作是否已经发生;在否定句中,表示某动作尚未发生。例如:
Have you seen the new movie yet?(你已经看过那部新电影了吗?)期望得到关于是否看过电影的回答。
I haven't eaten breakfast yet.(我还没吃早饭。)说明目前 “没吃早饭” 的状态。
3.just(刚刚):用于肯定句和一般疑问句,位于助动词 have/has 之后,行为动词之前。表示动作刚刚结束不久。例如:
He has just come back from school.(他刚从学校回来。)描述回来这个动作刚完成。
Have you just arrived here?(你刚到这儿吗?)询问到达这个动作是否刚发生。
4.ever(曾经):多用于否定句或疑问句。在疑问句中,询问某人在过去的经历中是否做过某事;在否定句中,强调从未有过某种经历。例如:
Have you ever been to Beijing?(你曾经去过北京吗?)想了解对方过去有无去北京的经历。
I don't think I've ever seen such a beautiful flower before.(我觉得我以前从未见过这么漂亮的花。)突出以前没有这样的经历。
5.never(从不):用于否定句,位于助动词 have/has 之后,行为动词之前。表示从过去到现在都没有发生过某个动作。例如:
She has never traveled by plane.(她从未坐过飞机旅行。)强调一直没有坐飞机旅行的经历。
They have never eaten sushi before.(他们以前从没有吃过寿司。)说明在过去的时间里都没有吃过寿司。
(二)与表示一段时间的状语连用
1.for + 时间段:表示动作从过去开始,持续到现在,可能还会继续持续下去。此时句中的谓语动词必须是延续性动词。例如:
I have lived in this city for ten years.(我在这座城市已经住了十年了。)从十年前开始居住,一直持续到现在,且有可能继续住下去。
He has studied English for three years.(他学英语已经三年了。)三年前开始学习英语,到现在还在学习。
2.since + 时间点:也表示动作从过去某一时刻开始,一直持续到现在。since 后面接的是一个具体的过去时间点,如 since 2010(从 2010 年起),since last week(从上周起)等。同样,句中的谓语动词要用延续性动词。例如:
We have known each other since we were in primary school.(自从我们上小学时就认识彼此了。)从小学那个时间点开始,认识这个状态一直持续到现在。
She has worked in this company since 2015.(她自 2015 年以来就在这家公司工作。)从 2015 年开始工作,一直持续到现在。
3.since + 一般过去时从句:这种结构也是表示从过去某一动作发生时开始,一直持续到现在。从句中的动作是一个过去发生的短暂动作,主句的谓语动词为延续性动词。例如:
I have lived here since I came to this city.(自从我来到这座城市,我就一直住在这里。)“came to this city” 是过去发生的短暂动作,从那时起 “live here” 这个动作一直持续到现在。
He has been ill since he caught a cold last week.(自从上周他感冒后,就一直生病。)“caught a cold” 是过去的短暂动作,之后 “be ill” 的状态持续到现在。
(三)与其他时间状语连用
1.in the past/last + 时间段:意为 “在过去的…… 时间里”,表示从现在往前推一段时间,在这段时间内发生的动作对现在有影响。例如:
In the past few years, we have made great progress in our studies.(在过去的几年里,我们在学习上取得了很大的进步。)强调过去几年的学习情况对现在的影响,现在处于有进步的状态。
She has read many books in the last month.(在上个月里,她读了很多书。)说明上个月读书这个动作对现在知识储备等方面可能产生的影响。
2.so far(到目前为止):表示从过去到现在的一段时间,常与现在完成时连用,强调动作从过去开始一直持续到现在的结果。例如:
So far, we have learned about 1000 English words.(到目前为止,我们已经学了大约 1000 个英语单词。)体现从过去开始学单词,到现在积累的数量。
The project has been going well so far.(到目前为止,这个项目进展顺利。)描述项目从开始到现在的整体情况。
3.recently(最近) /lately(近来):这两个词意思相近,都表示在最近的一段时间内发生的动作对现在有影响。例如:
I have seen her recently.(我最近见过她。)说明最近发生的 “见她” 这个动作对现在有影响,可能现在还记得她的样子等。
He has been very busy lately.(他近来一直很忙。)表明近来这段时间他处于忙碌的状态,这种状态持续到现在。
