Here's one way...
Code:
$ cat file1
(S1 (S (NP (NP (DT The) (JJ beautiful) (NN view)) (PP (IN of) (NP (JJ outside) (NNP greenery)))) (VP (VBZ adds) (NP (DT a) (NN tranquil) (NN touch)) (PP (TO to) (NP (DT this) (NN place)))) (. .)))

$ cat prog.awk
    {
        for (i = 2; i <= length($0); i++) {
            x = substr($0, i, 1)
            if (c > 0) {
                b = b x
                if (x == "(") c++
                if (x == ")") c--
            }
            if (c == 0 && substr($0, i, 3) ~ /^\([NVP]P$/) {
                if (b) print b
                b = x
                c++
            }
        }
    }

    END {
        if (b) print b
    }

$ awk -f prog.awk file1
(NP (NP (DT The) (JJ beautiful) (NN view)) (PP (IN of) (NP (JJ outside) (NNP greenery))))
(VP (VBZ adds) (NP (DT a) (NN tranquil) (NN touch)) (PP (TO to) (NP (DT this) (NN place))))
