1、Unit 5Period 2. 阅读理解AWhen the natural climate changes due to global warming, it can surely affect seals. The majority of them live in the Antarctic region, so as the ice is melting, their natural habitat can be seriously affected. These changes dont take place overnight. They can be the result of ma
2、ny years of additional temperatures in the area. The seals then have to find ways to adapt. Seals depend on the cool air currents to bring plenty of food for them.

3、eed their babies. Many of them end up abandoned as the mothers have to leave to find their own source of food. The fact that their desire to produce young can be changed by the warmer temperatures is frightening, too. It is also believed that the warmer temperatures can allow different diseases and
4、viruses to attack the seals. This is a huge concern as they can rapidly wipe out huge numbers of seals out there. However, these changes in climate and temperature arent all bad for other species of seals. Scientists have found that those living in warmer climates are producing more young due to the
5、 changes. Research also shows that the females are moving further to find food and water. When they are out of the reach of the governing males, they are more willing to accept the moves of other males in the group. This is good news too because it means that there will be more selection in the gene
6、 pool(基因库)for future generations. It can help the seals as a species adapt to change in their natural environment more easily. The climate change problem for seals is directly linked to humans. When we take action to change what we let out into the environment, we will make positive changes for the
7、seals. However, it is going to take a very long time to reverse (彻底改变)the effects of what has already been done. 【语篇概述】本文主要介绍了气候变暖对南极地区海豹的影响。1.

8、equirement for more choice in the gene pool. 【解析】选A。推理判断题。文章第一至三段介绍了气候变暖对南极地区海豹的负面影响, 第四、五段介绍了气候变暖对其他海豹种类的正面影响。由此可知, 在作者看来, 气候变暖对海豹既有利又有弊, 是把双刃剑。2.

9、hange a great deal. D.

10、otecting SealsB. Seals Adaptation to Climate ChangeC. How Climate Change Affects SealsD.

Studies show that public schools across the country are cutti
11、ng back on music classes to save money. Worse, some schools have never had music classes to begin with. But without them, students academic growth and emotional health could suffer. In fact, music classes are necessary for all students in schools. Recent studies by Brown University have shown that s
12、tudents who received music education classes were better in math and reading skills than those without music classes. Another study by The College Board found that students taking music and art classes got higher points. Students academic success seems to depend on their taking part in music educati
13、on. Music programs in public schools also help to add to a students sense of pride and self-confidence. Teens today have too many learning tasks. Besides, they have family problems, self-confidence problems, relationship troubles, and choices about drugs and alcohol. All of these can stop academic s
14、uccess, but music education can help. A study by The Texas Commission on Drug and Alcohol Abuse found that students who took part in school music programs were less likely to turn to drugs. Music programs encourage students to work together to produce an excellent performance. Music crosses language
15、, class, cultural and political boundaries (界限). Music allows students from different countries to connect. For example, at a school talent show, a new Japanese student played a piano duet (二重奏) with an American classmate. Although they could not communicate verbally (口头上), they were able to read th
16、e music in order to play the duet. Two students from different cultures worked as a team with self-confidence and common purpose through music. The gift of music is priceless. We need to be sure to have necessary music classes for all students. The world is losing its music, and putting music into s
17、chools is the first step to get it back. 【语篇概述】本文是一篇说明文。作者结合目前很多学校不重视音乐课这一现象, 提出音乐课对于孩子们身心等多方面的益处, 突出本文的目的即呼吁学校让音乐课回归课堂。4. Education with music classes could _.
