Please check & correct my mistakes:

In English:
One day sarah went shopping.
Then she walked to her house
Unfortunately it started to rain
Fortunately sarah had a jacket
All of a sudden sarah fell down
Finally sarah arrived at her house

In French:
Un jour sarah fait du shopping
Puis elle a marche a la maison
Malheureusement il a commence a pleuvoir
Par chance sarah a une veste
Tout a coup sarah tombe
Enfin sarah arrive a sa maison

I'll send this to our French expert, SraJMcGin.

Alright but when will I get a response back? This is due tomorow and I really don't want any mistakes:)

First of all, capitalize a proper name, regardless of the language. Have end punctuation where necessary. French words that require accent marks are incorrect if they are missing those accent marks.

You seem unaware of the difference between the Past Tense and the Present Tense: walked, started, had, fell down, arrived = ALL Past Tense Verbs for which you used the Present, or forgot a necessary accent mark.

Invest in a good dictionary and here is how to use it: 1) take the English word and look up the French, 2) write down all the possibilities 3) take each possibility and look it up now from French to English. Look for the primary (not secondary, tertiary, etc.) meaning. Then you will know which word to use. (this may not be important for this exercise, but keep it in mind for later.

Now I'll correct your French and flag this so I can come back later to answer any questions you might have.

Un jour Sarah (or Sara in French) a fait des emplettes (or des courses, depending upon your text book). Puis elle a marché chez elle (or, à sa maison.) Malheureusement il a commencé à pleuvoir. Heureusement Sarah (or Sara) avait une jaquette (une veste is a coat). Tout à coup Sarah (Sara) est tombée par terre. Enfin Sarah (Sara) est arrivée chez elle (à sa maison.)

The vocabulary you are to use is totally dependent upon the text book/workbook, etc. you use for class.

Please add any questions below.

Oh ok I understand now:) thank u very much for the help:) I really appreciate it:)

In English:

One day, Sarah went shopping.
Then, she walked to her house.
Unfortunately, it started to rain.
Fortunately, Sarah had a jacket.
All of a sudden, Sarah fell down.
Finally, Sarah arrived at her house.

In French:

Un jour, Sarah est allée faire du shopping.
Ensuite, elle a marché jusqu'à sa maison.
Malheureusement, il a commencé à pleuvoir.
Heureusement, Sarah avait une veste.
Soudain, Sarah est tombée.
Enfin, Sarah est arrivée chez elle.

Your sentences in English and French look very good! There are just a few minor corrections to be made:

1. In English, capitalize the first letter of each sentence.
2. In French, use "est" instead of "fait" to indicate an ongoing action in the present tense.
3. In French, use "jusqu'à" instead of "a" to indicate "until" in the phrase "Elle a marché jusqu'à sa maison."
4. In French, use "est tombée" instead of "tombe" to indicate that Sarah fell down in the past tense.

Great job overall!
