四、阅读理解

When 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 don’t take place overnight.They can be the result of many 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.When the temperatures get higher,there is less and less food and the seal population starts to shrink.Mothers aren’t healthy enough to feed 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 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 aren’t all bad for other species of seals.Scientists have found that those living in warmer climates are producing more young due to the 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 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 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.

1.What does the author regard climate changes for seals as?

A.A double-edged sword.

B.An unavoidable disaster for existence.

C.A mirror of evolution.

D.A requirement for more choices in the gene pool.

答案:A

解析:推理判断题。文章第二、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种类海豹的正面影响,由此推知,在作者看来,对海豹来说,气候变暖既有利又有弊,是把双刃剑。故选A项。

2.What will happen to the seals in warmer climates?

A.Their number will be on the increase.

B.The female seals will be in the lead.

C.Their genes will change a great deal.

D.The females will keep away from the males.

答案:A

解析:细节理解题。根据第四段中的“Scientistshavefoundthatthoselivinginwarmerclimatesareproducingmoreyoungduetothechanges.”可知,那些生活在较暖和地区的海豹会因为气候变暖而繁殖更多的幼崽。由此可知,它们的数量会增加。故选A项。

3.Which of the following can be the best title for the text?

A.The Importance of Protecting Seals

B.Seals’ Adaptation to Climate Change

C.How Climate Change Affects Seals

D.Why Are Seals Becoming Less and Less

答案:C

解析:标题归纳题。根据全文内容可知,本文主要讲述了全球气候变暖给海豹带来的负面影响和正面影响,因此C项“气候变化如何影响海豹”最适合作为本文标题。

五、七选五阅读理解

Imagine a child standing on a diving board four feet high and asking himself the question:“Should I jump?”This is what motivation or the lack of it can do.Motivation and goal setting are the two sides of the same coin.　1　 Like the child on the diving board,you will stay undecided. 

　2　 More than that,how should you stay motivated to achieve the goal?First,you need to evaluate yourself,your values,your strengths,your weaknesses,your achievements,your desires,etc.Only then should you set your goals. 

You also need to judge the quality and depth of your motivation.This is quite important,because it is directly related to your commitment.There are times when your heart is not in your work.　3　 So,slow down and think what you really want to do at that moment.Clarity(清晰) of thoughts can help you move forward. 

Another way of setting realistic goals is to analyse your short and long term objectives,keeping in mind your beliefs,values and strengths.Remember that goals are flexible.　4　 They also need to be measurable.You must keep these points in mind while setting your goals. 

Your personal circumstances are equally important.For example,you may want to be a pilot but can’t become one because your eyesight is not good enough.　5　 You should reassess your goals,and motivate yourself to set a fresh goal. 

You will surely need to overcome some difficulties,some planned,but most unplanned.You cannot overcome them without ample motivation.Make sure that you plan for these difficulties at the time of setting your goals.

A.This can affect your work.

B.So how should you motivate yourself?

C.However,this should not discourage you.

D.So why should we try to set specific goals?

E.They can change according to circumstances.

F.Motivation is what you need most to do a good job.

G.Without motivation,you can neither set a goal nor reach it.

答案:1~5 GBAEC
