It is your responsibility! (1)

Now it is a busy season for our company. Everyone works very hard and they still need to work overtime to complete their tasks. Most of us fulfill our duty well, however, there is someone complaining a lot under the pressure and asking others to do her job. If we cannot satisfy her, she will yell at the office and blame the clients with anger. A few weeks ago, I delievered a duty to her according to our procedure. She did tell me that it's a little difficult to solve. I suggested that she call some related offices for a solution. It seemed that she couldn't solve it after so many days and she delievered this tough job to a new colleague. I felt she was very ridiculous and irresponsible. If she, who has worked on this kind of thing for over one year, cannot solve the problem, how dare she think that that totally new colleague, who has nothing experience, can do it. I really think she was bulling the incomer. After all, if the problem cannot be solved at last, the client will only blame the incomer rather than her. 

problems like this at work are so frustrating!

Can you help me correct below ?

Motorbikes are the best traffic vehicle and are convenient for most of the people in my country. We can use motorbikes to go to work ,to school , to the market, and to do a lot of activities. Motorbikes are small, easy to move anywhere, and affordable with the income of working people.
However, besides the convenience, they also have many disadvantages such as: they cause traffic jams when you go work or school in the morning and after work and school on the way home. They also cause environmental pollution, causing traffic accidents.
Above are all I know about convenience and inconvenience when you use motorbikes.

很好！ When you talk about an object that is not specific you should make it plural (more than one).  If you were writing about <em>your</em> motorbike, it would be singular (just one).

What do the words girlfriend and boyfriend mean to you?

I consider a boy my boyfriend when they ask me if I will be their girlfriend.  In America, a boy will ask a girl on a date to eat dinner or see a movie, and after a few dates they may ask her to be their girlfriend.
