一、连词成句。
1. play on don’t road the football
.
2. my is in March birthday
.
3. is going Dongdong to cake a eat
.

1. Don't play football on the road
2. My birthday is in March
3. Dongdong is going to eat a cake

1. 该题是否定祈使句，遵循"Don't+动词原形短语+地点状语"的结构，固定搭配play football表示“踢足球”，on the road表示“在马路上”，将词汇按规则组合即可得到通顺的句子。
2. 该题是主系表结构的陈述句，形容词性物主代词my修饰birthday作主语，is为系动词，固定搭配in March作时间状语放在句末，按顺序组合即可。
3. 该题是一般将来时的陈述句，用到be going to结构表示“打算做某事”，主语为Dongdong，后接be动词is，going to后接动词原形eat，a cake作eat的宾语，组合后得到正确句子。

二、阅读短文,判断句子正(T)误(F)。
There are lots of birthdays in Tim's family in a year. Tim's birthday is on the 16th of September. His mother's birthday is on the 11th of March. His father's birth-day is on the sixth of January. Grandpa's birthday is in October. Grandma's birthday is in August. They are both on the 24th.
()1. Tim's birthday is on the 17th of September.
()2. His father's birthday is on the 11th of March.
()3. The birthdays of Tim's grandparents are both on the 24th.
()4. The birthday of Tim's grandma is in August.

1.F 2.F 3.T 4.T

我们可以对照短文内容逐题判断：
1. 短文里写明Tim的生日是9月16日，题目说他的生日是9月17日，和原文内容不符，所以该句错误。
2. 短文里Tim爸爸的生日是1月6日，3月11日是Tim妈妈的生日，题目描述和原文不符，所以该句错误。
3. 短文说明爷爷的生日在10月，奶奶的生日在8月，两人的生日日期都是24号，和题目描述一致，所以该句正确。
4. 短文直接提到奶奶的生日在八月，和题目表述完全一致，所以该句正确。
