Krista Richard lives in Canada. She has helped kids enjoy fun bike rides for fourteen years. She collects old bikes, repairs (修理) them and gives them to children for free. Her small kind act brings great joy to thousands of kids.

Last year, over 400 bikes got new owners. This year, Krista gave away 88 bikes in one day.  Bikes bring kids happiness and also bring neighbors together. Kids usually stay home and play video games alone, but riding bikes helps them make friends easily.

Lots of children are still waiting for bikes. Many kids write to thank her. They say the bike is their best gift.Krista feels proud and warm.

1.1.Where does Krista live?

A Canada.

B China.

C The UK.

D The USA.

解析：选A。A 细节理解题。文章开篇第一句就明确告诉我们“Krista Richard lives in Canada.”，这是可以直接在文中找到的明确信息，因此她住在加拿大。选项B China、C UK和D USA在整篇文章中都完全没有提到，所以不能选。故选A。

2.2.How many bikes did she give out last year?

A 88.

B About 300.

C Over 400.

D 100.

解析：选C。C 细节理解题。题目询问的是去年的送车数量，文中第二段第一句指出“Last year, over 400 bikes got new owners.”，说明去年有超过400辆自行车找到了新主人，这与选项C完全一致。选项A的88是今年某一天送出的数量，选项B和D在文中没有依据，因此不选。故选C。

3.3.What helps kids make friends easily?

A Playing games.

B Riding bikes.

C Watching TV.

D Reading books.

解析：选B。B细节理解题。文中在第二段最后部分提到“riding bikes helps them make friends easily”，直接说明了骑自行车这件事能帮助孩子们轻松交到朋友。选项A的玩游戏在文中是孩子们独自在家玩的电子游戏，并没有帮助交友；选项C和D在文中均未出现，所以排除。故选B。

4.4. What is the best title for this passage?

A A Bike Shop.

B Krista’s Kind Act.

C How to Fix Bikes.

D Kids and Games.

解析：选B。B 主旨大意题。全文围绕Krista坚持多年收集、修理旧自行车并无偿送给孩子的善举展开，讲述这件事给孩子们带去快乐、增进邻里交往，因此最能概括全文内容的标题是“Krista’s Kind Act”。选项A“一家自行车店”与文章内容无关，选项C“如何修理自行车”只是文中一个细节并未展开说明，选项D“孩子与游戏”仅在对比时一笔带过，都不是文章中心。故选B。
