Remember that a paraphrase needs to show your own ideas, not just someone else's ideas in a slightly different wording from the original. You are presenting your own ideas based upon sources, not merely reporting those sources.
Take notes carefully, noting page numbers and placing quotation marks around words that you copy from the original. Use only exceptional words or phrases quoted in this way.

Morris, Desmond. Manwatching. New York; Abrams, 1977.
Unfortunately, different countries have different ideas about exactly how close is close. It is easy enough to test your own "space reaction": when you are talking to someone in the street or in any open space, reach out with your arm and see where the nearest point on his body comes. If you hail from western Europe, you will find that he is at roughly fingertip distance from you. In other words, as you reach out, your fingertips will just about make contact with his shoulder. If you come from eastern Europe, you will find you are standing at "wrist distance." If you come from the Mediterranean region, you will find that you are much closer to your companion, at little more than "elbow distance."
Regrettably, different nations think differently about exactly how close is close. Test yourself: when you are talking to someone in the street or in any open space, stretch your arm out to measure how close that person is to you. If you are from western Europe, your wrist will reach the person's shoulder. If you are from the Mediterranean region, you will find that you are much closer to your companion. You elbow will reach the other person's shoulder (Morris 131).
People from different nations think that "close" means different things. You can easily see what your reaction is to how close to you people stand by reaching out the length of your arm to measure how close someone is as the two of you talk. When people from western Europe stand on the street and talk together, the space between them is the distance it would take one person's fingertips to reach to the other person's shoulder. People from eastern Europe converse at wrist-to-shoulder distance. People from the Mediterranean, however, prefer an elbow-to-shoulder distance (Morris 131).

Raudepp, E. "Daydreaming." Success Unlimited. Nov. 1975: 64.
During times of stress, daydreaming erects a temporary shield against reality, in much the same way that building a house protects our bodies from the elements. Both may be seen as forms of escapism, but no one wants to spend life in an unrelieved battle for survival. We are entitled to occasional strategic withdrawals to regroup our forces.
Just as we construct buildings to shield ourselves from extreme climate and weather conditions, our minds create daydreams as protection against difficult emotional situations (Raudsepp 64).
Our minds create daydreams to protect us from pressure (Raudsepp 64).
