英语中共有12种时态:

1. 一般现在时:I eat breakfast every day.(我每天吃早饭。)

2. 现在进行时:I am eating breakfast now.(我现在正在吃早饭。)

3. 现在完成时:I have eaten breakfast.(我已经吃过早饭了。)

4. 一般过去时:I ate breakfast yesterday.(我昨天吃了早饭。)

5. 过去进行时:I was eating breakfast when you called me.(你打电话给我时我正在吃早饭。)

6. 过去完成时:I had eaten breakfast before you came.(你来之前我已经吃了早饭。)

7. 将来时:I will eat breakfast tomorrow.(我明天会吃早饭。)

8. 将来进行时:I will be eating breakfast at 7:00 tomorrow morning.(明天早上7:00我会正在吃早饭。)

9. 将来完成时:I will have eaten breakfast by the time you arrive.(你到达之前我会已经吃过早饭了。)

10. 现在完成进行时:I have been eating breakfast for 30 minutes.(我已经吃了早饭30分钟了。)

11. 过去完成进行时:I had been eating breakfast for 30 minutes when he came.(他来的时候我已经吃了早饭30分钟了。)

12. 将来完成进行时:I will have been eating breakfast for 30 minutes by 7:00 tomorrow morning.(明天早上7:00的时候我会已经吃早饭30分钟了。)

至于疑问句的结构,一般情况下都是将助动词放在主语前,构成“助动词+主语+谓语”的形式,例如:

- Are you hungry?(你饿了吗?)

- Does he like coffee?(他喜欢咖啡吗?)

- Did you go to the store yesterday?(你昨天去商店了吗?)

- Will she come to the party tonight?(她今晚会来参加派对吗?)

- Has he finished his homework yet?(他已经做完作业了吗?)

英语冷知识
答案

学习英语这么多年,总结了些英语冷知识:

1、The most used letter in the English alphabet is 'E', and 'Q' is the least used!

英语中使用最多的字母是“E”,用的最少的字母是“Q”

2、The quick brown fox jumps over a lazy dog.

这句话包含了字母表中的所有字母

3、More people in China speak English than in the United States.

会说英语的中国人比会说英语的美国人还多。

4、The word "uncopyrightable" is the longest English word in normal use that contains no letter more than once.

"uncopyrightable"是英语里面最长的无重复字母的常见单词。

英语几倍的表达方式及区别
答案

英语中,“几倍”的表达方式主要有两种:“times”和“multiplied by”。两者之间有一定区别,具体如下:

1. “times”表示“倍”,用来表示一个数值是另一个数值的多少倍。例如:

- This shirt is three times more expensive than that one. 这件衬衫比那件贵三倍。

- The new car is twice as fast as the old one. 新车是老车的两倍快。

2. “multiplied by”也表示“倍”,但多用于数学计算或科学语境中,表示一个数值乘以另一个数值的结果。例如:

- The area of the room is 5 meters multiplied by 6 meters. 这个房间的面积是5米乘以6米。

- The speed of light is approximately 186,282 miles per second multiplied by the square root of -1. 光的速度约为每秒186,282英里乘以-1的平方根。

简而言之,“times”用于表示一个数值是另一个数值的多少倍,而“multiplied by”多用于表示一个数值乘以另一个数值的计算结果。
