I’m Tom. Last Sunday afternoon, I learned to make dumplings. First, Mom put flour (面粉) and water together to make soft dough (软面团). She cut it into small round pieces. I put filling in the middle. But I put too much. The filling came out everywhere. My mom laughed and helped me fix it. I tried again slowly. This time my dumpling looked nice. We boiled them in hot water. They tasted delicious.

1.1.When did the writer learn to make dumplings?

A On Saturday morning.

B On Sunday afternoon.

C On Sunday morning.

D On Saturday evening.

解析：选B。B细节理解题。根据第二句“Last Sunday afternoon, I learned to make dumplings”可知作者周日下午学包饺子。故选B。

2.2.What does Mum mix with water for dough?

A Flour.

B Rice.

C Egg.

D Milk.

解析：选A。A细节理解题。根据第二句“Mom put flour and water together to make soft dough”，妈妈把面粉和水混合做成面团，A 选项对应原文信息，B、C、D 文中未提及。故选A。

3.3.What does the word “it” refer to?

A The flour.

B The dumpling.

C Hot water.

D A small bowl.

解析：选B。B词义猜测题。前文汤姆放太多馅料，馅料溢出来，饺子坏掉了，妈妈帮忙修整这个饺子。这里it指代包坏的饺子，B选项转述指代内容，其余选项不符合上下文逻辑。故选B。

4.4.What do we know about the dumplings?

A They tasted bad.

B They were too hot.

C They tasted great.

D They looked ugly.

解析：选C。C推理判断题。根据结尾“They tasted delicious”，delicious表示美味的，C选项用简单词汇替换原文单词。故选C。

5.5.What is the main idea of the passage?

A Tom’s mom cooks food.

B Tom’s happy trip on Sunday.

C Tom buys nice dumplings.
