Visiting the city can be really     1     (challenge) when you are six months pregnant (怀孕的) and have a 3-year-old girl. One spring afternoon, we went to a store nearby to buy some food. There was no sign of rain    2     the store was just around the comer, so we went there without     3     umbrella. However, when we were about     4     (leave) the store, the rain started to pour down and the streets    5     (cover) with water within minutes. I noticed a young Chinese couple    6     (stare) at us when we came to a crossroad and were waiting for the light to change    7     (anxious). I figured they were probably wondering     8     a pregnant foreigner was taking her little kid out through the rain. But as we crossed the street, the woman offered me her umbrella. I refused, but she handed it to me and hurried off with her husband.

Though    9     (catch) in the rain unexpectedly, we still treasure the memory and will remember the warmth and    10     (kind) of the Chinese couple forever.

The story is about what Sam felt about his     1    (one) boarding school life.

    2     a child,he never left his parents,so he didn’t get used to     3    (deal) with everything in school independently.

Once I had a similar experience.I finished my junior middle school in a boarding school.At the age of 13,I     4     dealt with the daily things,such as washing clothes,taking care of money etc,    5    (especial) I felt lonely because I hardly knew any people.At first,I could not get on well with my classmates and I always looked forward to     6    (be) on holiday to meet my parents.I could not concentrate on my subjects.As time went by,I gradually adapted     7    (me) to the school life.I made several friends with our classmates and often took part in the activities,in which I improved my communicating skills.As I had a lot of interesting things to do,I     8    (final) enjoyed my school life.

Every country has a system of manners, that is, rules for behavior Each particular culture has a history of     1     (accept) behavior. People teach these manners to their children, Everyone in a culture     2     (usual) agrees on what is good behavior and what is not.

When you visit a new place, you need to learn     3     manners for that place. But what will happen when many different people come together? What if they do not know the rules in this place?

The company hired     6    bravest riders and bought the fastest horses     7     (use) as relay(替换) teams between Missouri and California, and the company promised     8    mails would be sent in ten days. The company established two hundred stations along the route at which riders could rest and change horses. In less than two years,     9     , telegraph lines were completed and the Pony Express was     10     longer needed.
