1.and可不可以连接句子
and:和,并e.g.I like English,maths,and Chinese.Please stand up,come over here and clap my hand.基本用法:连词“and”表示“和”、“并且”的意思,用来连接并列关系的词和词、短语和短语、句子和句子.e.g.Do you have a pen and a ruler?通常,单词或词组如果是三个或三个以上连接,一般在最后的单词或词组前加and.特殊用法:祈使句,+ and… = If(如果) you…,you'll …e.g.Study hard,you'll make big progress.= If you study hard,you'll make big progress.。
2.and可以连接一分词短语和一介词短语吗
不可以。
对等连接词and连接的词性必须是相同的,如连接名词与名词、代词与代词、片语与片语,或主从复合句中同级的从句等。如:
The soldiers walked quickly and quietly.
The book is of use and of interest.
Do it in haste and with caution.
There are magazines and magazines in that bookstore.
Go and buy some eggs.
He said that his brother was out and that his sister was home.
3.关于and和“,”连接句子的问题
The traffic rule says young children( under the age of four and____less than 40 pounds)
must be in a child safety seat.
从句中主语是
young children which is under the age of four and .weighing less than 40 pounds
主语是young children 和weigh存在主动关系,所以用ing和and没有关系,and只是连接句子,只是句子主语省略在前面。
D就是是非谓语动词
若是两句句子
l am a student,and he also is a student
连接两句句子,用(,and)。或者(;)或者直接(。)
4.And连接的句子,前后时态一致
高中的时候做题老师可能这样讲。
但实际在口语中并不一定的
and可以连接语法作用相同的词、短语或句子,表示并列或对称的关系,可翻译为“和”、“并”、“又”、“兼”等。
1. 连接两个并列主语。如:
Millie and Amy go to the park every week. Millie和Amy每周去公园。
2. 连接两个并列谓语。如:
You must take care of yourself and keep healthy.你必须照顾你自己并保持健康。
3. 连接两个简单句。如:
They love playing football and we love playing football too.他们喜欢踢足球,我们也喜欢踢足球
二、表示动作的先后关系
And常用来连接两个动词或动词词组,后面一个动词所表示的动作比前面的动作发生得迟一点,可翻译为“然后”。如:
Go along the street, and take the second turning on the right,you will find the cinema.沿着这条街走,然后在第二个路口向右拐,你就会发现电影院。
He got out of the lift and climbed the fifteenth floor on foot.他从电梯里走出来,然后步行爬上第十五层楼。
以上情况,前后时态一致
但是
Copper______ used by humans and is second only to iron in tis utility through the ages.
A, the first metal
B, was the first metal
C, the first metal that
D, being the first metal
答案选B
语法笔记中一再强调平行结构,特别是and连接时一定要一致,可这道题时态就明显不一致呀
这种情况也是存在的。望采纳!
5.【两个and连接的语句有什么意义像下面的语句:$db
语句A && 语句B 只有 语句A 和 语句B 同时 为 真的 时候,(语句A && 语句B ) 才为真.计算机在判断的时候,首先判断 语句A ,如果语句 A 为假的话,语句B 将会被忽略,也就是不运行语句B只有 语句 A 为真,才会继续判断 语句 B 是否为真.所以 $db_cvtime!=0 && $timestamp += $db_cvtime*60; 你给的这个如果 $db_cvtime 为0 ,$db_cvtime!=0 为 假,那么 $timestamp += $db_cvtime*60; 将不会执行.如果 $db_cvtime 不为0 ,则继续执行 后面的语句!其实这里相当于if($db_cvtime!=0){$timestamp += $db_cvtime*60; }不过用 && 显得更简洁.。
