36・34 Points $1,2,3,4,5$ are marked on a circle in a clockwise direction. A frog jumps from one point to another in a clockwise direction around the circle. If it stops at an odd-numbered point, it can only jump one point the next time; if it stops at an even-numbered point, it can jump two points. The frog starts from point 5 and makes 1995 jumps. After 1995 jumps, the point it will stop at is
(A) 1 .
(B) 2 .
(C) 3 .
(D) 4 .
(E) 5 .

［Solution］The frog's movement path is
$$
\text { (3) } \rightarrow 1 \rightarrow 2 \rightarrow 4 \rightarrow 1 \rightarrow 2 \rightarrow 4 \rightarrow \cdots
$$

That is, starting from the 2nd jump, it repeats every 3 jumps.
Since $1995-1=1994 \equiv 2(\bmod 3)$, the frog will stop at the point labeled 4 after 1995 jumps. Therefore, the answer is $(D)$.
