I don't think a correction is necessary. Both parts of the sentence are already in the present tense. Plus, the use of "us" in the beginning of the sentence indicates a personal attachment.
B. Roots
Roots are the smallest meaningful parts of words. For example the root word of aquamarine would be Aqua, which means water. So the root word can also give you a hint on the meaning of the word.
Hope this helps :)
