As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
70. Pollution of water is noticed________.
A. when the first organisms are affected
B. when a good many fish and birds die
C. when poisonous things are poured into water
D. as soon as the balance of nature is destroyed
71.The living things die because there is no ________in the lake or river.

D. make special room in the sea for our rubbish
There is a scene in the movie The Descendants and it went something like this ---George Clooney’s character Matt King has a daughter who may be 9 or 10. She said something bad to a girl at her school that made her cry. The mother of that girl made Matt and his daughter come to their house to apologize. “Sorry,” said his daughter very casually. She was clearly not sorry for her actions and the girl’s mother complained she didn’t take her apology seriously. Matt shrugged(耸)his shoulders. What was he supposed to do? His daughter apologized as asked. He couldn’t make her mean her words.
I always think of this story when my daughter is asked by other adults to apologize for her wrong doings. I know my daughter is being taught to say “sorry” with all the best intentions. They are teaching her to be polite. But she is apologizing because she is being forced to please the adult or to avert punishment.
This situation has happened on a few occasions and it really bothers me. Here are three reasons why I don’t think it’s a good idea to teach children to say sorry: 1. My daughter is being taught to say things that are not from her heart. 2. She is being taught insincerity(不真诚) is valued over genuineness. 3. She is being taught she needs to please others to be loved.
These messages make me uncomfortable and I will not ask my children to apologize. Instead, this is what I think people should teach children:
teach them behavior that is acceptable and to practice positive behavior.
teach them how their actions affect others.
give them space to think about the situation and ask them to suggest ways to make the situation better.
help them make healthy choices
lead by example and show them how to fix wrong doings The story in Paragraph 1 mainly shows that ________.
| A．sometimes people don’t take their apology seriously |
| B．The Descendants is a good film that is worth seeing |
| C．forcing a child to apologize may not get expected results |
| D．parents should punish their children for their mistakes |
What does the underlined word “avert” in Paragraph 2 mean?
| A．Suffer | B．Avoid | C．Deserve | D．Get |
From Paragraph 3 we can learn that the author ________.
| A．doesn’t like apologizing to other people. |
| B．doesn’t think apologizing is important to children |
| C．doesn’t think her daughter has done anything wrong |
| D．thinks forcing a child to apologize has disadvantages |
According to the last paragraph, the author suggests people should ________.
| A．teach children how to become independent |
| B．teach children how to apologize in the correct way |
| C．teach children to behave well instead of forcing them |
| D．teach children how to set a good example to others |

Each of us can live strong, healthy, energetic lives for a long time to come. The key？Actually, there are many of them.
Eat fewer calories, but more food
Slimming down can help prevent disease, and cutting way back on the amount you eat may even slow the aging process. When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health：Pile your plate high with vegetables and fruits, add respectable parts of beans and whole grains, and ignore high-calorie food like cheeseburgers, cream sauces, and fatty meats.
Use exercise as an anti-aging vaccine
Exercise can help you gain a better quality of life as you age. It's no secret that physical activity strengthens muscles, burn calories, and puts a happy bounce in your step. But recently, researchers discovered a new, extra benefit：Exercise acts as a powerful way against the aging process itself. When exercise physiologists put healthy people aged 60 to 85 on Weight-training programs for six months then tested them for signs of free-radical(自由基) damage, they were surprised by the results. By the end of the study, low-intensity exercisers had a drop in free-radical damage, while high-intensity exercisers had a slight increase.
Find something interesting to do
Life is always busy no matter what your age. But the truth is, when people are retired, time usually does become more available for adults after 60. With this time come choices. The easy one is merely to relax：watch more TV, eat out more often, talk on the phone as much as you want. The better choice? Discover something more meaningful to devote yourself to and do it wholeheartedly.Which of the following is what you should eat more?
| A．Fatty meats. | B．Whole grains. |
| C．Cream sauces. | D．Cheeseburgers. |
The new discovery of exercise probably is that__________.
| A．it can help you live a better life |
| B．it can strengthen muscles |
| C．it can burn calories |
| D．it can prevent aging process |
When do you have more free time according to this text?

| C．Over seventy | D．Before sixty. |
The best title of this text should be "_______".
| A．How to Keep a Balanced Diet |

Everywhere I look outside my home I see people busy on their high-tech devices, while driving, walking, shopping, even sitting in toilets. When connected electronically, they are away from physical reality.
People have been influenced to become technology addicted. One survey reported that “addicted” was the word most commonly used by people to describe their relationship to iPad and similar devices. One study found that people had a harder time resisting the allure of social media than they did for sleep, cigarettes and alcohol.
The main goal of technology companies is to get people to spend more money and time on their products, not to actually improve our quality of life. They have successfully created a cultural disease. Consumers willingly give up their freedom, money and time to catch up on the latest information, to keep pace with their peers or to appear modern.
I see people trapped in a pathological（病态的）relationship with time-sucking technology, where they serve technology more than technology serves them. I call this technology servitude. I am referring to a loss of personal freedom and independence because of uncontrolled consumption of many kinds of devices that eat up time and money.
What is a healthy use of technology devices? That is the vital question. Who is really in charge of my life? That is what people need to ask themselves if we are to have any chance of breaking up false beliefs about their use of technology. When we can live happily without using so much technology for a day or a week, then we can regain control and personal freedom, become the master of technology and discover what there is to enjoy in life free of technology. Mae West is famous for proclaiming the wisdom that “too much of a good thing is wonderful.” But it’s time to discover that it does not work for technology.
Richard Fernandez, an executive coach at Google acknowledged that “we can be swept away by our technologies.” To break the grand digital connection people must consider how life long ago could be fantastic without today’s overused technology.The underlined word “allure” in Paragraph 2 probably means ______.
| A．advantage | B．attraction |
| C．adaption | D．attempt |
From the passage, technology companies aim to ______.
| A．attract people to buy their products |
| B．provide the latest information |
| C．improve people’s quality of life |
| D．deal with cultural diseases |
It can be inferred from this passage that people ______.
| A．consider too much technology wonderful |
| B．have realized the harm of high-tech devices |
| C．can regain freedom without high-tech devices |
| D．may enjoy life better without overused technology |
What’s the author’s attitude towards the overusing of high-tech devices?
| A．Neutral. | B．Sceptical. |
| C．Disapproving. | D．Sympathetic. |
One morning when I was 11, I explored the town’s abandoned round grain barn（谷仓）. I found a chained sliding door that was wide enough for me to pass through.
Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降机井) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.
I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall.
After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found…absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher（灭火器）,which I’d always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn’t breathe. I was going to choke to death, and they’d probably never even find my body.
Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.
I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I’m not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.When the author got inside the barn, he _______.
| A．noticed a man on the elevator |
| B．opened the chained sliding door |
