Grammar exercise | English homework help

please read pages 133-136 and 140-150, and please complete the following sets of exercises.  The associated pages of instruction and the exercise instructions get more mechanical/technical than I prefer to get with grammatical instruction, but these are issues I am seeing in your essays, so I figured it is worth having you check these things out and work with them a little bit. EXERCISE S1-1 on page 136 (This is in Section S1-c.) EXERCISE S3-1 on page 143 (This is in Section S3-d.) EXERCISE S3-6 on page 146 (This is in Section S3-e.) EXERCISE S4-1 on page 147 (This is in Section S4-a.) EXERCISE S4-3 on page 148 (This is in Section S4-b.) EXERCISE S4-6 on page 151 (This is in Section S4-5.)
