6．Whale Wars
    As I was looking through the channels I came upon something called Whale Wars．What a bunch of stupid people．I really don't believe these people are thinking straight．I know they are not thinking straight because one of the questions the captain asks of all new members or those who want to be members is this：Are you willing to die for a whale？One more time，just in ease you were not paying attention．Are you willing to die for a whale？No，I am not willing to die for a whale-are yon crazy？I don't mind jumping in there to help out on a cause，but to die for a whale or even any kind of animal is beyond my understanding．These people believe strongly enough in this cause to say"Yes，yes，I will die for a whale"．The countries involved in the whaling industry do this because it is a way to make a living and support their families．The last thing they need is to have a bunch of stupid people trying to disable their ship．
    A lot of the organizations out there say that whaling has to be stopped immediately without question．However，disabling these fishing boats will only stop the so-called problem temporarily．
  The point is this：It is so very easy for people to say stop the whaling!OK，you stop the whaling．What is your answer for an alternative to whaling？I'm waiting．How do you want these people to support their families and help fuel the economy in which they live？A lot of people want the whaling to stop，but they have little or nothing to offer as an alternative for them．You cannot just say stop something and then that is the end of the problem．
  Yes，I am picking on the"save the planet"people again．I will continue to do so until they can come up with better ideas on how to save the planet without putting people and what they own in harm's way．Destroying another person's things and putting them in a possible life or death situation is not the answer．
  Until whaling countries can figure something else out to cure this so-called problem，there really isn't a lot that can be done．Until this happens，I say raise the anchor，set the main sail and WHALE AWAY!

7．We don't know how different our future will be in the future．We can only try to imagine it．
At first we think about human relationship．In the year 2050，we will use computers almost every day．We will be making new friends through the Internet---even our husbands or wives will be met in this way．It will be much faster and easier for us．On the other hand，our relationships with people won't be as important as they are today---we will feel a little lonely．
    Computer will also help us in many other activities in 2050．For example，they will be used by the children at school to make their learning easier．In addition，there will be much more other machines which will play a similar role as computers，like robots which will do the housework for us．
    Spending holidays will also be completely different．Traveling to other planets or to the moon will be available for everyone．Means of transport will，of course，change，too．We will be using solar-powered cars，which will cause less pollution．
    We could expect that the faster technological progress would lead to more attention to protecting the environment．And，scientists will probably find cures for many dangerous diseases，like cancer or AIDS．Therefore，our surroundings as well as health will be in a better condition．
    Although we can't predict the exact changes which will be made in the world，we often think about them．We worry about our and our children's future； we have expectations，hopes as well as fears．But I think we should be rather sanguine about our future．We should be happy and believe good things will happen．
66．Why will people probably feel a little lonely in 2050？B
A．Because the number of people will become much smaller．
B．Because there will be less face-to-face communication．
C．Because people won't communicate with each other much often．

A．that computers will do all the things for human beings．
B．how people will use computers to communicate with each other
C．that machines like computers and robots will help people a lot．
D．how people will use robots to do the housework．
68．According to the passage，which of the following will happen in 2050？C
A．The relationship between people will be more important than today．
B．The way of spending holidays will be the same as that of today．
C．It won't be difficult for people to travel to other planets．
D．Our environment will be much more polluted with a growing number of cars．

11．A cat is recovering in California after surviving a 6，500-mile journey across the Pacific stowed inside a Chinese shipping container without food or water．Staff and volunteers have named it"Ni Hao，"which is Chinese for"hello．"
It was discovered breathing shallowly after a two-week trip across the Pacific Ocean．The cat was seriously suffering from loss of water and starvation when the container was opened in California last week，but was said to be doing well after being sent to the Carson Animal Care Center in Los Angeles．At first it was too weak to stand，but finally took its first steps．Then it ate a good meal and slept soundly．The cat woke up Thursday morning，physically in a better condition than 24 hours ago．
"Ni Hao greeted the medical team with its first miaow this morning and is attempting to stand，"said Marcia Mayeda，head of the Los Angeles Department of Animal Care and Control．Aaron Reyes，director of the Department，added："We finally got to hear its voice．It sounds like a single-engine plane．"
Ni Hao is expected to be observed for 60 days but afterwards animal workers will look forward to providing it with a good shelter．"It's much better for it to recover in a home environment，"Mr Reyes said．"It's just like a human being in a hospital so we're hoping to move it．"He added："Little by little we're getting there．We're hoping that under the treatment and with rest，it'll be able to recover quickly．''

1．It's common for parents to feel emotional when the moment comes for their child to leave home and go to university．Even parents who don't speak about the event are likely to feel a sense of sadness because it's the end of an era where you and your family were at the centre of your child's world．As a parent you'll probably continue to support your child in different ways，but the main job of raising your child is over．It's a huge change for everyone involved．
    There are a few things that you can do to make the transition easier．Plan carefully for your child's departure and think about how you can help．Many parents take their child to university for the first time．If you decide to do that，be ready to feel a real wrench when the time comes to say goodbye．Your child will probably be as nervous as you are about the moment when you finally say goodbye-but that might not show!
    Be positive and cheerful about the choice your child has made to continue studying，and plan to leave once you've unpacked the car and looked around your child's new living accommodations．If you can，save your tears for the car-you'll make things easier on your child and yourself．
    The more you've invested in being a parent，the more you'll feel a sense of loss，so the sadness you feel now is a sign that you've been a good mom or dad．Remind yourself that parenting is all about raising an independent and confident child who functions well without you．If your child quickly settles and starts enjoying himself，you should congratulate yourself．
    It's also only fair to allow yourself some time to grieve（悲痛）．Don't expect to pick yourself up and move on straight away．But you may decide to find a hobby or sport to fill your extra time．Perhaps you've always wanted to learn a new language，go to yoga classes or take up swimming．You may decide to spend more time with family and close friends，who are likely to be feeling the absence of your child as well．
    Agree on the best approach to staying in touch before your child leaves，and stick to your agreement．Try not to panic if your child doesn't respond immediately-remember，they're starting a new and busy life．
63．Why do parents feel sad when their child leaves home for college？D
A．Because the absence of their child makes them feel lonely．
B．Because their children will start a new life in college．
C．Because it means the end of love between parents and their child．
D．Because they are no longer the main focus of their children's life．
64．The underlined word"wrench"in Paragraph 2 means a feeling ofA．
A．sorrow       B．regret C．a(chǎn)nger       D．love
65．What does good parenting consist of？C
A．Supporting your child in different ways all the time．
B．Congratulating yourself when your child goes to college．
C．Preparing your child to stand on their own feet in the future．
D．Investing as much as possible in the growth of your child．
66．What's NOT advised as the way to recover from your child's departure？D
A．Devel oping a new hobby or sport
B．Learning a new language．
C．Spending more time with close friends
D．Staying in touch with your child．
67．What would be an appropriate title for the whole passage？C
A．Staying in Touch with Your Child
B．Preparing to Say Goodbye to Your Child
C．Dealing with Your Child Leaving Home for University
D．Life after Your Child Has Left Home for University．
