人教版(新课程标准)高中英语必修5 Unit 3同步练习二

阅读短文,从每题所给的A、B、C和D四个选项中, 选出最佳选项。

    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.

    Computers 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 solar­powered cars, which will be much more environmentally friendly.

    We could expect that the faster technological progress would lead to a more polluted environment. But it isn't true. We will pay 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 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 optimistic about our future. We should be happy and believe good things will happen.

(1)、Why will people probably feel a little lonely in 2050?
A、Because the number of people will become much smaller. B、Because there will be less face­to­face communication. C、Because people won't like making friends with each other. D、Because people won't communicate with each other much often.
(2)、The third paragraph mainly tells us ________.
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
(3)、According to the passage, which of the following will happen in 2050?
A、The relationship between people will be more important than that of 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.
(4)、What does the passage mainly talk about?
A、How people will communicate in the year 2050. B、What our life will be like in the year 2050. C、How people will travel and spend their holidays in the year 2050. D、What high technology will appear in the year 2050.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

DEAR Daughter,

    We have not seen you for a while now, so I thought we might check in. Did you fall off the edge of the Earth? Your mother worries, you know, and I am just curious. Well, I am more than curious. I feel abandoned.

    Apparently you've dumped us for your career. I can understand that, because you've always had a wonderful work ethic (道德).

    Look, obviously your long absence has confused us. As we go about our daily routines, your mother and I are distracted – both by your absence and our pride in your career. The other day, I entered my work password into the microwave, then stood there cursing it for not working. And I was so off my game (状态差) that I actually used that cholesterol-free mayo (不含胆固醇的蛋黄酱) your mother insisted on buying in an effort to drive me from the house.

    Listen, a lot has happened since you've been away. Abraham Lincoln was shot. We had two more children – a princess, now 23; a boy, now 12.

    Yesterday I bought a very clean 2001 Camaro car from an older woman. Your mother is not happy about this. She says it is the kind of muscle car driven by ex-convicts (有犯罪前科的人) when they examine your house at 2 am.

    In response, I tell her it was the car of my dreams (when I was 18). So that's where your long absence has left us. Your long absence is not so bad, though we miss your roaring laughter ... the way your cheeks flush (晕红) when you eat Thai food. How you always march too hard into the house, like a Scotsman stepping on snakes.

    Each evening, your mother now waits by the window the way she did when you used to step off the bus in first grade, your hair full of rubber bands.

    Bet that drove you crazy even then, her running out on the porch (门廊) like you'd just returned from a month-long journey to the moon.

    Look, parents are not easy people.

    But should the urge ever hit you, feel free to stop by some time. Our house is your house. Our hearts are yours too.

    And your mother is still waiting by the window.

Love,

Dad
