Put the verbs in brackets into the present perfect or the past simple. Use the full form of the verbs. I usually meet Kevin every day, but I (not/see) him since last week. We (speak) for five minutes on the phone yesterday, though.

1. The first blank requires the present perfect because of "since last week". The verb "see" in its negative present perfect form is "haven't seen".
2. The second blank requires the past simple because of "yesterday". The verb "speak" in its past simple form is "spoke".

Answer: haven't seen, spoke
