Bring a large saucepan of lightly salted water to a boil. Add the orzo and cook until tender, but still firm to the bite. Drain the pasta and set aside to cool.

Place the asparagus, pine nuts, and shrimp in a large salad bowl, mix well and then add the orzo.

Mix together the lemon juice, salt, pepper, sugar and olive oil in a small bowl. Pour the mixture over the salad and mix well. Keep in the refrigerator until ready to serve.
