课时作业13：Unit 3 Life in the future

Unit 3 Life in the future
Ⅰ.阅读理解
A
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 solar－powered 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 our 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.
1．Why will people probably feel a little lonely in 2050?
A．Because the number of people will become much smaller.
B. Because people won't communicate with each other much often.
C. Because people won't like making friends with each other.
D. Because there will be less face－to－face communication.
2．According to the passage，which of the following will happen in 2050?
A．It won't be difficult for people to travel to other planets.
B．The way of spending holidays will be the same as that of today.
C．The relationship between people will be more important than today.
D．Our environment will be much more polluted with a growing number of cars.
3．The underlined word “sanguine” in the last paragraph most probably means“_____”．A．disappointed B．optimistic
C．curious D．surprised
4．What does the passage mainly talk about?
A．How people will communicate in the year 2050.
B．What high technology will appear in the year 2050.
C．How people will travel and spend their holidays in the year 2050.
D．What our life will be like in the year 2050.
B
Mom noticed that something was wrong when I started getting so thirsty. I'd have a lot to drink before bed，which was unusual for me. One time, I opened a big container of apple juice and kept refilling my glass. Before I knew it, I'd drunk the entire container! My mom called my doctor.
I then had a few blood tests, and the results were certain—I had diabetes (糖尿病)，which meant that the amount of sugar in my blood was very high. That can be dangerous, so I had to learn how to control my blood－sugar level.
My eating habits had to change in a big way. With diabetes, I can't eat a lot of sugar or carbohydrates (碳水化合物). I have to figure out exactly how much sugar I plan to eat, and then I get an injection of insulin (注射胰岛素) before the meals to help my body process the food. Also，I test my blood－sugar level often. I'm always trying to keep my blood sugar at a healthy level. The level can drop when I exercise，but that doesn't keep me out of gym class or off the basketball court—I just keep some juice boxes around to boost my blood sugar if I need to.
It's a lot of work—and not a lot of fun—to keep track of everything，but I've gotten used to my new habits. I was a little scared at first because I wasn't sure how my life would change. Once I knew what I needed to do，though，it wasn't a big deal. My life is different now from what it was before，but it has become completely regular to me.
5．The first paragraph is mainly about _____.
A．who found the author had diabetes
B．the author's life before having diabetes
C．how the author was found to have diabetes
D．the author's eating habits before having diabetes
6．The insulin injected into the body before the meals can _____.
A．change people's eating habit
B．help process the food
C．hasten the growth of organs
D．prevent high blood level
7．What did the author do after knowing she had diabetes?
A．She stopped playing basketball in the gym.
B．She controlled her blood－sugar level strictly.
C．She stopped eating food with natural sugar.
D．She tested her blood－sugar level before every meal.
8．What does the underlined word “boost” in Paragraph 2 mean?
A．Increase.B．Control.
C．Absorb.D．Test.
