3. Je lui parle. = I speak, do speak, am speaking TO HER (indirect-object pronoun)
5. je parle avec toi = je te parle = right = I speak, do speak, am speaking TO YOU.
Here's the problem with the French.
Je le/la/les vois = I see HIM/IT, HER/IT, THEM. (direct object pronouns.
Je lui/leur parle = I speak TO HIM, TO HER, TO THEM. (indirect-object pronoun)
When you see the English: I write him. you need to REWORD it to "I write (a letter, etc. = direct object) TO HIM (indirect-object pronoun.
If when you reword it you either say or have understood TO, FOR, AT, FROM you have a indirect-object pronoun.
I have review sheets but I suspect you don't really need them. Just let me know! :)
I used to tell my students in Level I: you are building a wall. You must have a firm foundation upon which you will build Level II. Then you need a firm foundation to build Level III. If you draw a well with GAPS, they quickly see how the wall falls down on the next level.
In fact, in Level V we used to look at the "hit list" (the mistakes they kept making) and there were NOT from Level IV or even III, but usually Level I OR Level II. In my book, Level II is the most important of all, because it reviews Level I and starting with Level III, you've had all the grammar. Then you put whatever you have to work! :)
