2. We only a playground three years ago. But we have a big gym now.
3. We a new classroom now. a big computer in it.
4. My school is really big. four playgrounds in my school.
5. not many cars before，but there are cars everywhere now.
答案
1. There was
2. had
3. have; There is
4. There are
5. There were
2. had
3. have; There is
4. There are
5. There were
解析
1. 句子描述的是二十年前房子后面有一个小花园，是存在关系，用there be句型，twenty years ago表示一般过去时，a small garden是单数，be动词用was，且句首需大写，所以填There was。
2. 根据three years ago可知句子是一般过去时，主语是we，“有”用have的过去式had。
3. 第一句now表示现在，主语we，“有”用have；第二句描述教室里有一台大电脑，是存在关系，用there be句型，a big computer是单数，be动词用is，且句首需大写，所以填There is。
4. 句子描述学校有四个操场，是存在关系，用there be句型，four playgrounds是复数，be动词用are，且句首需大写，所以填There are。
5. before表示以前，句子是一般过去时，“没有很多汽车”是存在关系，用there be句型，many cars是复数，be动词用were，否定形式是were not，可缩写为weren't，且句首需大写，所以填There were。
