8、programs. D. Life-long free admission to the museum.BThis past summer I went on a journey to Canadas Arctic with Students On Ice. When I left Calgary, I wondered what I would find, what I would learn and who I would meet. On the trip to Ottawa I was wrapped in a blanket of uncertainty and excitement
9、. But when I first met the group of students. Scientists and leaders. I knew that I didnt have anything to worry about. The group was amazingly receptive and I was soon part of a big family setting out on an amazing adventurean adventure of a lifetime!When we reached the Arctic, I saw a vast land th
10、at appeared untouched and original.I was surprised by its great size and beauty and my senses were repeatedly shocked and amazed. I stood on the Kapitan Khlebnikov and saw twelve polar bears. They walked in search of seal holes and patiently waited for a meal. I learned that polar bears are successf
11、ul only one out of every twenty hunting attempts.However, I learned that the Arctic and its people are being threatened by pollution and global warming. I learned that pollutants are carried by ocean and air and have a bad effect on all Arctic people. I learned that global warming has put polar bear
12、s at risk because a warmer climate means that they have a shorter time to hunt seals on the ice. The trip was a feast for the senses. I have learned more about our environment and particularly how alive and interesting the Arctic is and why it is so important to take care of it. I learned pollution
13、ignorance of individual and global problems need to be solved. The Arctic deserves to be preserved. My trip with Students On Ice has made me more determined to try to ensure that I do not leave harmful footprints on either Earth or its people.24. What can we learn from the first paragraph?A.

How did the writer feel about the trip according to the last paragraph?A. Surprising. B. Alarming. C. Appealing. D. Rewarding.27.

Polar Bears and MecScientists have found an unexpected use for virtual reality headsets (耳机).The devices,widely used by computer gamers, show pic
17、tures that can be used to test the navigational(导航)skills of people, who were thought to be at risk of dementia (痴呆).Those who do worse in the tests will be the ones more likely to develop Alzheimers disease later in life. scientists now believe. The discovery that the loss of navigational skills wa
18、s associated with Alzheimers was made several years ago by Dennis m Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which we
19、arers are placed in man-made environments through which they must navigate. Around 300 people aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimers. Not all will cert
20、ainly be affected by the disease. However,Chans project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details. Researchers recently pointed out the significance of a tiny area of the
21、brain known as the entorhinal cortex (an important memory center in the brain). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimers. The goal of the work is to help people as they
22、develop the disease. “So far, drug trials for Alzheimers have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred,” Chan told the Obsenver. “ If we can develop drugs and use them earlier, for example, before the disease has spread b
23、eyond the entorhinal cortex, then this would have the potential to prevent the dementia.”28. What does the unexpected use of VR headsets mentioned in Paragraph 1 refer to?A. Making games more interesting for computer gamers.B. Testing ones potential to develop dementia.C. Helping people suffering Al
24、zheimers recover.D. Reducing the risk of having dementia.29. What are the participants required to do in the study?A. Know unfamiliar environments by using tablet computers.B. Identify directions in some man-made environments.C. Play computer games by using navigational skills.D. Create special envi
25、ronments by using navigational skills.30. Whats implied(暗示) about the entorhinal cortex in the brain?A. Its functions have been known for years.B. It can be expanded by using VR headsets.C. It can directly affect ones navigational skills.D. Its size depends on that of ones memory center. 31. From Ch
26、ans words we can know A. he will spread the new drug B. he will try out the drugC. the study helps to prevent dementia D. the study still needs to be improvedDAfter decades of cat-and-mouse between athletes and the world anti-doping agency(WADA), athletes found what they must have believed to be the
27、 ultimate (终极的)doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then,months later, just before a competition, you can re-inject (注射)the old blood for a boost. As the red-bl
28、ood-cell count goes up,so does an athletes ability to absorb oxygen. The more oxygen you get with each breath , the more energy your body is able to burn and the better you are able to perform. Although the enhancement is small to actual drugs, it can be the difference between a gold medal and a sil
29、ver medal. Best of all,“extra blood” was never something WADA tested for .But WADA wasnt going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP).The idea is to record some biological features of an athl
30、ete through testing done at regular intervals. The biological passports partial implementation (实施) recording blood and steroid levelsbegan in January 2014.When all necessary biological features are finally combined,WADA will no longer need to worry about finding new methods to detect a drug. It wil
31、l only have to detect (检测)resulting changes in the body. In the case of blood doping,if the athletes normal red-blood-cell count is,say,47%,but then is found to be 51 % after a competition, cheating may have been involved. WADA is confident that the biological passport could even prevent genetic cha
32、ngesthe ultimate,ever-lasting enhancementwhich are surely coming next. If an athlete inserts a performance enhancing gene,it will probably leave detectable changes in the body,that would differ from the athletes feature in the biological passport.32.
