第一节(共15小题；每小题2分，满分30分)
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
Dolphins are not fish, but warm-blooded animals． They live in groups, and speak to each other in their own language． In this way they are like other animals, such as bees and birds． But dolphins are very different from almost all land animals． Their brain is nearly the same size as our own, and they live a long time—at least twenty or thirty years．
Like some animals, dolphins use sound to help them find their way around． They also make these sounds to talk to each other and to help them find food． We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw．
Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people．
There is a story about sailors in the 19th century． In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack． From 1871 to 1903 Jack met every boat in the area and showed it the way． Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack． He recovered and for nine years more continued to guide all ships through the area—except for The Penguin．
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them．

B
A teenager needs to have a sense of independence in their life to feel secure． To some teenagers independence means a lot to them, and I think that some parents don’t allow their teenagers enough independence．
Independence has something to do with freedom． Some kids are not allowed to go anywhere alone, and the only thing their schedule includes is going to school, coming home, going to sleep, and repeating the process the next day． Parents tend to be afraid that their kids can get hurted if they go outside into the world． But if parents control their kids too much, they may never learn to live on their own． The best way for a teenager to learn lesson is through experience． I think it is beneficial for teenagers to have freedom．
Teenagers’ lack of freedom can also stop them from having good friendship at
school． Some might say that this is a good thing, because it helps them focus more on their school work． I argue that this can only discourage them not to do their school work． Some parents do not allow their children to be around their friends outside the school, thinking that this will get them into trouble． But I don’t think so． Instead, isn’t this a good reason for parents to get their children a cellphone? Cellphones allow teenagers to stay in touch with their parents, and communicate better with their friends．
Privacy is another issue between parents and their teenagers． Teenagers tend to enjoy relaxation by themselves in their own room． This also gives them a sense of independence． It often annoys teenagers when their parents enter their room when they are not home． I know that my mom always goes in my room when I’m not home, and this has brought me to the point where I have asked many times to get a lock on my door．
【解题导语】 本文介绍了青少年需要自由和独立这个话题。父母不应该对孩子管束太多，要发展孩子的独立能力。
5．What is the main idea of the second paragraph? A．Kids know how to live independently． B．Some parents allow their kids no freedom． C．It benefits teenagers to have freedom． D．Kids have a dull routine every day．
C 解析：段落大意题。第二段的主题句是I think it is beneficial for teenagers to have freedom．根据第二段的内容也可知道，本段主要说的是自由对于青少年的发展很有好处。
6．In the opinion of the author, ________．
A．parents should make it easy for kids to communicate with their friends B．good friendships between kids harm their school work C．it is unnecessary for a kid to have a cellphone D．kids should focus on the school work
A 解析：推理判断题。根据文中的Instead, isn’t this a good reason for parents to get their children a cellphone? Cellphones allow teenagers to stay in touch with their parents, and communicate better with their friends．可知，作者认为应该给孩子手机，让孩子和朋友保持联系。
7．How do teenagers usually feel when their parents enter their rooms in their absence? A．Disappointed． C．Angry．
B．Lucky． D．Calm．
C 解析：细节理解题。根据文中的It often annoys teenagers when their parents enter their room when they are not home．可知，在孩子不在家时进入孩子房间会让孩子很生气。故选C项。
8．The author hopes to have her door locked in order to ________． A．keep her father from reading her dairy B．prevent her mother entering her room C．protect herself from any harm D．stop thieves from going in
B 解析：推理判断题。根据文章的I know that my mom always goes in my room when I’m not home, and this has brought me to the point where I have asked many times to get a lock on my door．可知，作者要求锁门是因为不想让母亲进入自己的房间。
C Kids’ lives should be filled with fun and excitement． Every parent wants their child to be able to look back on their childhood with memories filled with good times and humor． One of the ways to keep these memories is with a set of kids bunk beds．
For one thing, both children and parents get into the excitement of new bedroom furniture． For parents up the necessary money to buy something special themselves because new beds mean that they are growing up．
Use the shopping experience as a means of starting to teach your children economics． For example, explain to them that you have X amount of money to spend on the new beds． It may not mean much to the kids now, but it will plant a seed(种子) that money plays an important role in buying things．
Another learning method that can be employed for buying kids bunk beds is to have them reach certain goals． Explain to your children that they are growing up and therefore need “big kids” beds． However，you have to be sure they are really grown up enough for the new beds!
Give them some goals to achieve that are age proper． Some examples would be to take the rubbish out every day without being told, read one or two books and be able to tell you what they were about, be able to say the ABC’s or count to 10． This will give your children a sense of achievement and ownership of their new beds．
Getting kids bunk beds with a desk will also improve good learning habits． Have your children sit at the desk to do their drawing or coloring; this will improve the habit of doing homework at the desk．
Help your children learn and have fun with their new kids bunk beds!
