At Hangzhou East Railway Station, there is a free night train for waiting passengers. From 10 p.m. to 8 a.m., people with a ticket can stay inside.

The train has comfortable seats that can turn into beds. Each guest gets a blanket, a small light, and a box for valuables (贵重物品). There is hot water and plugs (插座) too.

1.1.When can people stay in the free night train?

A At 11 a.m.

B At 9 p.m.

C At 7 a.m.

D All day long.

解析：选C。C细节理解题。文章第一段明确指出：“From 10 p.m. to 8 a.m., people with a ticket can stay inside.”（从晚上10点到早上8点，持票乘客可以待在车内）。因此，乘客可以停留的时间段是晚上10点到早上8点。选项A“At 11 a.m.”（上午11点）不在该时间段内；选项B“At 9 p.m.”（晚上9点）比开始时间早1小时，不可停留；选项D“All day long”（全天）与文章限定时间段不符；选项C“At 7 a.m.”（早上7点）正好落在晚上10点到早上8点之间，符合文章描述。故正确答案为C。

2.2. What is NOT provided (提供) in the night train?

A A small light.

B A warm blanket.

C A mobile phone.

D A valuables box.

解析：选C。C细节理解题。文章第二段提到：“Each guest gets a blanket, a small light, and a box for valuables.”（每位乘客得到一条毯子、一个小灯和一个贵重物品盒）。因此，提供的物品包括毯子（对应选项B）、小灯（对应选项A）和贵重物品盒（对应选项D）。文章没有提到提供手机（mobile phone），且其他部分也未提及手机相关服务。故选项C是未提供的物品，为正确答案。

3.3. The night train is safe mainly because ________.

A the seats are soft

B police are there

C it’s only for women

D water is hot

解析：选B。B 细节理解题。文章第三段指出：“The train is safe and quiet. Staff and police watch over it all night.”（列车安全安静。工作人员和警察整夜看守）。由此可知，安全的主要原因是警察和工作人员的看守。选项B“police are there”（警察在场）直接对应此信息。选项A“the seats are soft”（座位柔软）与舒适度相关，但非安全主要原因；选项C“it’s only for women”（仅限女性）不准确，因为文章说“Some coaches are just for women”（有些车厢专为女性设置），并非全部列车；选项D“water is hot”（热水）是便利设施，与安全无关。故正确答案为B。

4.4. What’s the main purpose of this night train service?

A To sell more tickets.

B To show new trains.

C To train the staff.

D To help passengers rest.

解析：选D。D 细节理解题。文章最后一段强调：“This kind service helps travelers rest well. Many people like this warm idea.”（这种服务帮助旅客休息好。许多人喜欢这个温暖的主意）。这表明服务的主要目的是帮助乘客休息。选项D“To help passengers rest”（帮助乘客休息）直接匹配此描述。其他选项：A“To sell more tickets”（出售更多车票）、B“To show new trains”（展示新列车）、C“To train the staff”（培训员工）在文章中均未提及，且与文章内容无关。故正确答案为D。
