Is this argue true?Pleased help

Hello,
I am trying to learn Fielter but there is a problem with me.Could you explain me the a sentence in my text book.
This is the sentence:
"As illustrated in view B, the diode cannot conduct on the
negative half cycle because the anode of D1 is negative with respect to the cathode."
view B is attached in bellow.
In this diagram I think that during negative half cycle, as far as I see, [pleased correct me if it is a silly thinking], I ONLY know the voltage between diode and capacitor is negative.But in above argue, it is said that the voltage of anode is negative with respect to the cathode.Could you explain me this?
Thanks.

The text is correct. On the negative half-cycle the anode becomes negative so the diode does not conduct. Then the junction of the cathode and the capacitor stays at 0V or at a a positive voltage.
