Engelsk oversættelse

Jeg har oversat teksten fra dansk til engelsk. Er der en venlig sjæl som vil læse den igennem og rette kongurens og grammatik fejl? 
Tak på forhånd

Tina Jensen wanted to get better at English, so now she is on a half-year stay in the United States with a typical American family.
She lives with the family, Jackson, who lives in one of Philadelphia's suburbs. The family's children, who are 7 and 10 years old, are very sweet, so Tina’s workload is not overwhelming. One thing that surprised Tina is the old-fashioned family pattern: the children's mother is a nurse on a part-time basis, but she spends a lot of time volunteering with homeless and sick. The children's father is a bank manager on more than full time. – The Bank's opening hours is not long, yet he often comes home late.
When the children are taken to school, is the Tina’s task to do clean the House and buy into. She prefers to use the local merchants instead of the city's major supermarket, butcher and greengrocer with; she has the opportunity to speak more English.
In the afternoon, the children a happy drink lemonade and eat some pieces of toasted bread along with Tina, while they tell her about the day's experiences. Tina has become good friends with the neighbor's daughter, and when she has a day off, they together to Philadelphia by train.
It is a half hour drive to Philadelphia's Center. Tina’s friend Tina have shown many of the sights on the reason for the store's many offerings. Mr. Jackson's parents live in Miami Florida, United States, and the family takes soon there to spend 14 days’ vacation with them.
United States-the stay has been Tina to change the setting to what she will be when she comes home. Before she left, she would be in a company's foreign correspondent Department, but now she will combine his language skills with her knowledge of humans. Maybe a job at an asylum center in Denmark as an option before she reads on.</o:p>
