用所给动词的正确形式填空。 1. Kate, don't forget ______ (buy) some bread. There is little at home. 2. I ______ (not watch) TV yesterday, because I had a lot-八年级英语
－表示安慰、关心、喜欢、讨厌等感情色彩。
He is always making noises in class. （讨厌）
－在条件、时间、让步状语从句中表示将来正在进行。
Don’t bother him if he is reading this time tomorrow.
二、严格区分进行时与一般时的语义
1. 持续动词的一般时表持续情况，经常性，习惯性行为或客观存在的事实，进行时表暂时性或有限时刻的持续。
2.短暂动词的一般时叙述事实，特征，能力而短暂动作进行时描述反复发生，即将发生或刚开始行为。
3.短暂动词和静态动词一般时表示实际情况客观状态、结果、特征、特性，进行时表未完成含开始或渐进之意。
The bus stops. （车停了－事实）
The bus is stopping. （渐渐停下来）
I love the job. （静态事实）
I am loving the job. ( 渐渐爱上了）
4.come,go,leave,start,return,move,reach,sail,fall 等一般时态表客观规定计划，进行时表主观打算推测。
Flight 254 leaves at 5:30. （表主观打算）
The plane is taking off an hour later.（主观判断）
5.现在进行时带always,often,usually,sometimes，等频率副词表感情色彩，一般现在时则没有此用法。
一般现在时的句子转换：
（1）当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.
例：
①陈述句：She is a student.
疑问句→ Is she a student?
否定句→ She is not a student.
②陈述句：I can swim.
疑问句→ Can you swim
否定句→ I can not swim.
（2）当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数),does（单数she,he,it）变成问句；
在主语后谓语动词前加助动词don’t（I,you,以及复数), doesn’t（单数she,he,it）变成否定句，助动词后的动词要变成动词原形。
例：
①陈述句：We get up at 7:00 every morning.
疑问句→Do you get up at 7:00 every morning?
否定句→We don’t get up at 7:00 every morning.
②陈述句：She has a little brother.
疑问句→ Does she have a little brother?
否定句→ She doesn’t have a little brother.
一般现在时的表达方法：
主要通过谓语动词的变化和用时间词语来表示，其中最主要的是谓语动词的变化。现在一般时动词变化的规则是：
1.如果主语是名词复数和第一人称I、 we ，谓语动词不用做任何变化，即仍然用动词原形表示：
We usually go to school at 7:30. 我们通常7:30上学去。[go]
My parents give ten yuan to my sister every week.我父母每星期给我妹妹十元钱。[give]
2.主语是任何一个单数名词或者是第三人称单数，谓语动词要进行必要的变化。特别提一点：不可数名词也算作单数处理。
3.谓语动词的变化规律是：
