Will do 与be going to do 的用法差别

初中不定式todo的用法

1. 不定式的用法------1.1 不定式作主语不定式作主语，往往用it作形式主语，真正的主语不定式放至句子的后面。例如：It's so nice to hear your voice. 听到你的声音真高兴。 It's necessary for you to lock the car when you do not use it. 不用车的时候，锁车是有必要的。 It's very kind of you to help us. 他帮助我们，他真好。 It seemed selfish of him not to give them anything. 他不给他们任何东西，这显得太自私了。但是，用不定式作主语的句子中还有一个不定式作表语时，不能用It is… to…的句型。另外，这样的句子，不能用动名词作表语。例如：（对）To teach is to learn. （错）It is to learn to teach. （错）To teach is learning. （错）Teaching is to learn. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案：B. 如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 1.1.1 不定式做主语It's for sb/It's of sb to do sth 这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for或of 的区别。 1）for sb.句型中的形容词一般为表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：例如： It's very hard for him to study two languages. 对他来说学两门外语是很难的。

be going to的用法

一、be going to 的用法点拨 be going to 是一种固定结构，它后面要接动词原形，用来表示按计划或安排要发生的动作，有时也可以表示推测将要或肯定会发生的动作，有"准备；打算"的意思。含有be going to 结构的句子中往往有表示将来的时间状语。例如： We are going to have a class meeting this afternoon.今天下午我们打算开班会。(安排) Look at the black clouds. It's going to rain.看那些乌云，快要下雨了。(推测) 二、be going to 在肯定句中的形式 be going to 结构中的助动词be很少用原形，它一般有三种形式，即：am , is , are 。当主语是I 时用am ；当主语是第三人称单数时用is；当主语是其他人称时用are。例如： I am going to buy something tomorrow morning.明天早上我要去买些东西。 She is going to see Mr. Wang this afternoon.她打算今天下午去看望王先生。三、含be going to 的句子变否定句和一般疑问句的变法由于句子中有助动词be，因此be going to 的否定句和一般疑问句的构成很容易，即在be (am, is, are) 的后面加上not 就构成了否定句；把be (am, is, are) 放到句首，在句末加问号就构成了一般疑问句，其答语为：Yes, 主语+ am/is/are. / No, 主语+ isn't/aren't. / No, I'm not.不过I am... 在改为一般疑问句时常常改为"Are you ....?"。例如： They are going to see the car factory next week. (肯定句) They are not going to see the car factory next week. (否定句) -Are they going to see the car factory next week? -Yes, they are. (No, they aren't.) (一般疑问句及其回答) 四、使用be going to 应注意的两点 1. There be 句型的be going to 结构为：There is / are going to be... (注意句型中going to 后面的be不能改为have。) 常用来表示将有某事发生。例如： There is going to be a football match next Saturday in our school.下周六我们学校将有一场足球比赛。 2. come, go, leave, arrive等表示位置移动的动词常用现在进行时表示将要发生的动作，它们很少与be going to 结构连用。例如： Miss Sun is coming tonight.今晚孙小姐要来。

#pragma data code ICCAVR的使用

#pragma data:code 在Keil中为了节省数据存储器的空间，通过“code”关键字来定义一个数组或字符串将被存储在程序存储器中： uchar code buffer[]={0,1,2,3,4,5}; uchar code string[]="Armoric" ; 而这类代码移值到ICCAVR上时是不能编译通过的。我们可以通过"const" 限定词来实现对存储器的分配： #pragma data:code const unsigned char buffer[]={0,1,2,3,4,5}; const unsigned char string[]="Armoric"; #pragma data:data 注意：《1》使用ICCAVR6.31时，#pragma data :code ;#pragma data:data ; 这些语法时在"data:cod"、"data:data"字符串中间不能加空格，否则编译不能通过。《2》const 在ICCAVR是一个扩展关键词，它与ANSIC标准有冲突，移值到其它的编译器使用时也需要修改相关的地方。在ICCAVR中对数组和字符串的五种不同空间分配： const unsigned char buffer[]={0,1,2,3,4,5}; //buffer数组被分配在程序存储区中 const unsigned char string[]="Armoric" ; //stringp字符串被分配在程序存储区中 const unsigned char *pt //指针变量pt被分配在数据存储区中，指向程序存储区中的字符类型数据 unsigned char *const pt //指针变量pt被分配在程序存储区中，指向数据存储区中的字符类型数据 const unsigned char *const pt //指针变量pt被分配在程序存储区，指向程序存储区中的字符类型数据 unsigned char *pt //指针变量pt被分配在数据存储区中，指向数据存储区中的数据请问#pragma data:code和#pragma data:data是什么意思？前者表示：随后的数据将存贮在程序区，即FLASH区，此区只能存贮常量，比如表格之类。

will,begoingto,betodo,beabouttodo结构的区别

Will 和 be going to 结构的区别 1、（1）两者均可用来表示将来的意图，但"be going to"结构语义稍强些。例如： They are going to climb the Qomolangma one day. 他们准备/想将来某一天去爬珠穆朗玛峰。 1、（2）对于事先经过考虑的打算、计划、意图, 应使用be going to, 而不是w ill 结构。例如： — What are you going to do next Sunday 下星期天你打算干什么 — I'm going to go fishing. 我打算去钓鱼。 2、（1）对于未经过考虑的打算，计划，只是临时之意，则用will 结构，不用b e going to 结构。例如： — Where is the telephone book 电话号码簿在哪儿 — I'll go and get it for you. 我去给你拿。 2、（2）在表示即将发生某事时，两者区别意义不大，多可互换。例如： What is going to happen 就要发生什么事 What will happen 将要发生什么事一般说来，be going to 表示较近的将来，而will 则表示较远的将来。试比较： It is going to snow tonight. 今晚要下雪。 There will be a strong wind in a few days. 几天后将有一场大风。2、（3）表示不受人的主观意愿影响的单纯将来，一般只能用will结构。例如： Tomorrow will be April Fools' Day. 明天是愚人节。 2、（4）在正式的通知（如新闻媒体公布的官方消息，气象预报等）中用will 结构。例如： There will be a heavy rain to the south of Huai River. 淮河以南将有大雨。 3、be+to do，表示按照计划或正式安排将发生的事，主要指客观安排，必然趋势。 We are to discuss the report next Saturday. I am to play football tomorrow afternoon...(客观安排，如这儿有场比赛定在明天下午，不去不行，不能由主观决定)
