Is there something as truth？ For a good many centuries "the search for truth" has been (31) the noblest activity of the human mind, but the seekers after truth have come to such (32) conclusions that it often seems that very little progress has been made. (33) , there are many people who reel that we are actually going backward. They (34) , often contemptuously, that we have accumulated more "knowledge" than our ancestors, but they think we are farther from the truth than ever, or even that we have (35) the truth that we once possessed. If people look for anything long enough without finding it, the question naturally arises (36) the thing is really there to find. You have seen a picture of an animal with a lion's head, a goat's body, and a serpent's tail--and maybe an eagle's wings for good (37) There is plenty of evidence that each part of this animal (38) --but there is no (39) evidence that the parts ever occur in this combination.

听力原文：Donating blood plasma has always been a noble pursuit to help those in need. Since last September, there has been an upsurge in blood donations, as the need has become more emphasized and more empathized. But if you've had a tattoo or piercing within the last year, you will more than likely be turned away from any blood bank.
When you go to a blood bank to give plasma, they ask you a series of questions to determine if you are eligible to donate. Obviously, they don't want to risk accepting contaminated blood, so they will ask about your sexual history, current health status and other related questions, including whether or not you have gotten a tattoo or piercing within the last 12 months.
All blood that is donated is screened for disease such as HIV, Hepatitis, Syphilis and other common blood- born ailments.
However, it goes without saying that it is a waste of the blood bank's and the donor's time to harvest blood that is tainted and thus worthless.
So, in order to avoid wasted time, they ask these questions to screen the potential donor. And although even I would be quick to say that tattooing and piercing are much safer than some medical professionals like to indicate, there is still always a chance of getting and carrying a disease unknowingly from a tattoo or piercing, especially Hepatitis. That has been the object of many heated arguments and stringent regulations.
If you should happen to contract a disease from a tattoo or piercing, it should show up in a screening after 12 months, which is the reason for the waiting period. Yes, maybe it's a little over-precautious, but would you want to be the one on the receiving end of dirty blood？ If there, is even a chance, it is better to be safe than sorry.

A．Swim in public pools.
B．Give blood.
C．Over exert yourself.
D．Expose your skin to the sun.
