Every time we turn on the TV or take a ride in a car, we could be adding to a problem called acid rain(酸雨). In this article, we’ll learn something important about acid rain.
The formation of acid rain
When people use fuels (燃料), such as coal and gasoline(汽油), poisonous gases are given off. When these gases come together with rain, acid rain forms. Many power stations burn fuels in order to create the electricity(电) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline. When rain meets these gases, harmful things called acids form. This is acid rain.
The harm of acid rain
Acid rain destroys everything that it touches. It poisons our rivers, ponds and lakes and oceans along with the life in them. It pollutes our soils and crops, harm trees, and can even kill fish and plants. Acid rain also eats away at our buildings.
The prevention of acid rain
We need to reduce and even stop the pollution that gets into our air. Turn off lights, televisions and other electrical appliances(电器) if we are not using them. Walk and take a bike whenever possible. If we are travelling a long distance, take a bus or train to save fuel.
As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.
Whenever we use electricity or drive our cars we may add something bad to the air around us. And even worse, we may cause a terrible problem—acid rain. | |

One evening, Mark and Amy went for a ride in Mark's car. They parked on a hill. Mark turned on the radio, and a policeman broke in with a piece of news. He said a murderer had escaped from prison (监狱). The murderer's left hand was missing and in its place, he wore a hook (钩子).
"Let's close the windows and doors," said Amy.
"That's a good idea," said Mark.
"You know," said Amy, "that prison isn't too far away. I think we really should go home."
"Look, Amy," Marie argued, "that prisoner is not going to climb all the way up here. Even if he did, all the doors are closed. How could he get in?"
"Mark, he could take that hook and break the window," she said. "I'm scared. I want to go home!"
As he started the car, Amy thought she heard someone, or something, scratching (抓) at her door.
"Did you hear that?" she asked. "It sounded like somebody was trying to get in!" "Oh sure!" said Mark.

When we want to find out what the weather will be like tomorrow, we usually turn on the radio or TV. But in the time before radio and TV, people needed to forecast (预测) the weather. How did they do it? Let’s learn about two weather rhymes (押韵的诗) together.
Red sky at night, Sailor’s delight!
Red sky in the morning, Sailors take warning!
This weather rhyme was written a long time ago, but it still works today. As the sun is setting, a red sky at night usually means there are no clouds coming in from the west, a sign of good weather for tomorrow. But a red sky in the morning always means drier air is moving away to the east and moister air is moving in from the west. The moist air could bring clouds, rain and stormy weather.
When leaves show their undersides (底部), Be very certain, rain betides.
The rhyme shows us how trees forecast the weather. Tree leaves turn upside down just before it rains. In the period before a storm, strong winds can lift the leaves and show their undersides.
Animals, insects and plants are natural forecasters. When a summer storm is coming, you may notice that dogs, cows, horses, and geese grow restless (不安的) and frogs come out of their hiding places. These animals don’t have some sixth sense. Scientists think the animals can hear the low frequency (频率) sound waves made by thunderstorms many miles away.
Get outside and observe nature carefully, and soon you’ll be your own weather forecaster.
1.The underlined word “moist” can be replaced by the word “________”.
A.wet B.Cold C.warm D.clean
2.What is helpful for some animals to forecast the stormy weather?
A.Their sense of sight. B.Their sense of hearing.
C.Their sense of smell. D.Their sense of touching.
3.Which of the following is TRUE?
A.The two rhymes are both about winter weather.
B.When leaves show their undersides, it will be fine.
C.If you see a red sky in the morning, you can travel outside.
D.If you see a frog come out of its hiding place, you’d better stay at home.
4.What’s the writer’s main purpose in writing this passage?
A.To introduce two famous weather rhymes to us.
B.To tell us we should read as many rhymes as possible.
C.To show us the way to observe different animals.
D.To encourage us to get close to nature and observe the weather on our own.

If you’re riding in the car on the way home from school or soccer practice, does the sight of fast food restaurant signs make you hungry for a cheeseburger, some French fries or a piece of pizza?
Think about some of the signs for the most popular fast food restaurants. What do the signs for McDonald's, Wendy's, Burger King, Dairy Queen and Pizza Hut have in common? They all make prominent (突出的) use of two colors: red and yellow.
Could it be that these colors — red and yellow — make you hungry and want to stop for fast food? Although it might sound crazy, that's exactly what some scientists believe. The idea even has a name: the ketchup (番茄酱) and mustard (芥末) theory.
Scientists also point out that studies show that color gets communicated to the brain faster than any other type of communication. For example, experts believe that the color red inspires feelings of warmth, comfort and love. Similarly, yellow draws feelings of happiness, excitement and cheer.
Researchers believe that these colors, especially when used on fast food restaurant signs, create the perfect feelings to make us feel hungry and want to stop to eat.
Other scientists,however,disagree with the ketchup and mustard theory and point out that there isn't enough scientific data (数据) to support the theory. They think that feelings of happiness and excitement connected with the colors red and yellow aren't necessarily equal to hunger.
While the science of colors and their exact influence on us may be uncertain, it’s clear that fast food restaurants believe that in some way, it is good for them to include red and yellow on their signs. Do these colors make us hungry? Maybe ... or perhaps it’s our own happy memories of delicious cheeseburgers, salty French fries and ice- cold sodas that keep us coming back for more!
1.Why does the writer ask the question in Paragraph 1?
A.To know when people will feel hungry.
B.To ask people to take part in the research.
C.To get people into the topic of the passage.
D.To find what fast food restaurant sign is the most popular.
2.What common point do most fast food restaurants share?
A.They provide similar foods. B.Their foods are in red and yellow.
C.Their signs include red and yellow. D.Their foods are the favorite of people.
3.According to Paragraph 4, some scientists believe that ________.
A.people cannot refuse to enjoy fast food B.colors can make communication easier
C.people use colors to express their feelings D.colors have influences on our feelings
4.What can we learn from the last paragraph?
A.Colors are important to fast food restaurants. B.It’s uncertain whether colors make us hungry.
C.We need to study the science of colors. D.Delicious food can leave us good memories.

九年级英语单选题中等难度题查看答案及解析
Time is something that we all are taking for granted these days. We spend hours watching TV or playing mobile games, thinking that this is very normal. However, I find it a waste of time. 1. Every second is valuable and we should rethink of the ways of spending our time.
Firstly, spend time in doing things that are really important. Spend time with your family and friends. Enjoy a nice hot meal and eat it slowly. 2. Little things like this may seem meaningless. But the truth is that the little things matter most in life.
Secondly, you have to know what is done cannot be undone. 3. Every day is a new adventure. You have to keep your eyes and ears open to the new opportunity. It may not be an opportunity like an immediate chance you can get, but it may be an opportunity for new experiences.
4. If you have only one chance to do something for someone, why not try your best to do it? It should not matter whether you will be rewarded or not. You will take pride in your work because you’ve done your best. Trust me, your efforts will be rewarded in the end.
Lastly, every moment you spend time in doing things is the time taken from your life.
5. That is not your life’s worth. The value of your time is measured by how you spend it and whom you choose to spend it with.
A. Make a proper time schedule.
B. Do not allow your mind to stay in the past.
C. Because it is hours of our lives that we can never get back.
D. Give yourself time to play and spend enough time in sleeping.
E. Don’t spend your time in working day and night just for money.
F. Then, do your best in every task as if the world will end tomorrow.
