The students of Class Four are cleaning the classroom. Some are carrying water,others are sweeping the floor. 四班的学生们在打扫教室。一些人在打水,另一些人在扫地。

(3)the other

the other表示已知的两个(或两部分)人或事物中,特指的“另一个”或“另一些”,其后可跟单数或复数名词。

from

2. since,for在现在完成(进行)时中的用法异

(1) since 后接过去的时间点或一般过去时的从句。

He has been an English teacher since three years ago.

We he known each other since we came to study in this university.

3. 现在完成时与一般过去时的区别

现在完成时表示过去发生的某一动作对现在造成的影响和结果,强调的是现在的情况,所以它不能和表示过去的时间状语连用,如:yesterday, last night, three weeks ago, in 1990等。 而一般过去时只表示过去的动作或状态,和现在不发生了关系,它可以和表示过去的时间状语连用。如:

He has lived here since 1992. 1992年以来他一直住在这里。(他现在还住在这里) He lived here in 1992. 1992年他住在这里。(并不涉及他现在是否住在这里)
