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.

To get a hand in is to begin a job, to begin to know something about it. When we learned completely, it will be easy for us. We will be able to do it hands down. If we do the job well, we may end up with the upper hand. That means to be in control or to have gained complete understanding of a situation. On the other hand, if the situation gets out of hand then, it is out of control. Then we may have to hand it to someone, to let some- one else take over the business. It is time for us to wash our hands, to end it up completely. You can also lend a hand to someone but without really giving up your hand. You lend a hand when you help someone. You offer them a helping hand. If someone is kind enough to lend us a hand then we surely do not want to bite the hand that feeds us. We do not want to repay his kindness by treating him badly. The expression "to end up with the upper hand" means ______. A．to begin a job B．to be in control C．to be out of control D．to take over the business

Bartley was making his first trip on the whaling ship Star of the East. Suddenly the lookout sighted a huge sperm whale. The whalers knew it was a huge whale by the size of the spray it blew into the air. They lowered their small boats. James Bartley was in the first longboat. The men rowed until they were close to the whale. A harpoon was thrown and it found its mark. It sank into the whale&39;s flesh. The maddened beast crashed into the boat, snapping its tail at the men and the wreckage of their boats. When the survivors were picked up, James Bartley was missing. Shortly before sunset, the whale was finally captured. The sailors tied the whale&39;s dead body to the side of the ship. Because of the hot weather it was important that they cut up the whale right away. Otherwise, the meat would begin to rot and oil would begin to spoil. When they got to the stomach, they felt something moving about wildly. They thought it would be a big fish still alive inside. But when they opened the stomach they found James Bartley. After this trip, Bartley settled in England, and never returned to sea. 1、This passage is mainly about__________.

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