四年级英语时态变换与句型结构分析实战训练单选题40题1. My mother ______ (cook) dinner every day.A. cookB. cooksC. cookingD. is cooking答案：B。
解析：这题考查一般现在时。
主语my mother是第三人称单数，在一般现在时中，当主语是第三人称单数时，动词要用第三人称单数形式，即在动词原形后加s或es，cook的第三人称单数形式是cooks。
A选项是动词原形，C选项cooking是现在分词形式，D 选项is cooking是现在进行时结构，均不符合题意。
2. They ______ not play football on Monday.A. doB. doesC. areD. is答案：A。
解析：这是一般现在时的否定句。
主语they是复数，一般现在时中，复数主语的否定句结构是主语+do not+动词原形。
B 选项does是第三人称单数形式的助动词，C选项are和D选项is是be动词，在这里不适用，所以答案是A。
3. ______ your father go to work by car?A. DoC. IsD. Are答案：B。
解析：这是一般现在时的一般疑问句。
主语your father 是第三人称单数，一般现在时中，当主语是第三人称单数时，一般疑问句的结构是Does+主语+动词原形+其他。
A选项Do用于复数主语，C选项Is和D选项Are是be动词，不能用于这种情况，所以答案是B。
4. I ______ my homework every evening.A. doB. doesC. didD. am doing答案：A。
解析：这里考查一般现在时。
主语I是第一人称单数，在一般现在时中，第一人称单数做主语时，动词用原形。
B选项does 是第三人称单数形式的动词形式，C选项did是一般过去时的动词形式，D选项am doing是现在进行时结构，不符合题意，所以答案是A。

否定句：be动词（am、is、are）+not、情态动词can+ not、助动词（do、does） + not如何将一个肯定的陈述句改为否定句：1、看句中有无be动词，如有，直接在be动词后+ not。
2、看句中有无情态动词，如有，直接在情态动词后+ not。
3、如上述二者都没有，就应用助动词+ not。
分四个步骤：（1）肯定陈述句中本来是没有助动词的，要加上去，位置在主语（某人或某物）后，动词前。
（2）确定助动词用do、does，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，（3）在助动词后加not。
（4）原句中动词假如发生变化就要恢复成原形。
