“Why should I care about the environment?” some people ask. There is a very simple reason: We live on the earth, and it is the only place we can live on right now, as we cannot live in space yet. If we treat the earth like a garbage dump, it will become dirty and unlivable. If we treat it well by being eco-conscious, the earth will stay clean and suitable for living, for ourselves and for our children.
What is “being eco-conscious”?
Being eco-conscious means being aware of your actions, and what you do to the environment. For example, you might think, “Using hairspray is great for fixing my hair.” However, if you are eco-conscious, you would ask, “Does this hairspray have CFCs in it? Could I be destroying the earth by using hairspray?”
How can I be eco-conscious?
You can find many simple ways to help the environment in your everyday life.
When you go shopping, bring a bag or a basket with you. Please try not to use plastic bags as much as you can.
You can go to work by bike or on foot if it is not far from your home.
You can put your rubbish into different bags, which makes it convenient for recycling.
You can eat less chewing gum.
You can use your own chopsticks instead of the disposable ones in your company or in restaurants.
You can put batteries in a special box instead of in garbage bins.
You can use the water which has been used for washing vegetables or fruits to clean the floor and the toilet or to water your garden.
You can turn off the decorative lights in your room when watching TV.
You can turn down your air conditioner by one degree, as this will cause a 10% reduction in energy use.
You can use recycled paper. Every ton of recycled office paper saves 380 gallons of oil. You can also use recycled glass instead of glass made from raw materials. This will reduce the related air pollution by 20%, and the related water pollution by 50%.
Please believe that. If you do a little, it will make a big difference.
【小题1】Human beings should care about the environment because _________ .

Like most big projects, learning to manage your mother well is what you should do. Here are what I believe the best steps towards a better relationship with her. They are not necessarily surprising or revolutionary, but they have worked for many people. Try them.
Remember your mother’s age. As children, we often do not think of our mother as having an age. Even when we become conscious of her as an individual, age does not change our view; she is still our mother. Knowing our mother’s age, not just in numbers of years but in terms of her psychological and physical state, often helps us to understand her better.
Listen to your mother. I have found that sometimes the things my mother told me long ago are remarkably useful. If your mother knows that you respect her point of view, even if you do not share it, it will help her feel close to you.
Remember that your mother has a past. A key step in managing our relationship with our mother is to find out about her early life.In learning about our mother’s past, we know that it can encourage us to think about her whole life.
Ask your mother about your childhood history. My grandparents died when I was young. If you are fortunate enough to have living family, think of your life as a jigsaw puzzle and ask as many questions as you can to put the picture together. Understanding your roots and your childhood can help you know more clearly who you are, as part of a family which you share with your mother.
Remember that managing your mother is really about managing yourself. Taking any measure to managing our mother is the issue of how we manage ourselves. No matter how difficult we find her, it is important to remember that it is not her behavior itself that is causing us discomfort, but the way we feel about her behavior. We should follow the way of her life. At the heart of managing your mother is being able to accept your flawed self. Only then are you able to accept your mother-----with all her failings.
64. 【小题1】What does the underlined phrase “a jigsaw puzzle” mean?

A．to give information about how you think of your mother

B．to improve the relationship with your mother

C．to keep a sense of humor about your mother all day long

D．to accept your mother-----with all her failings

Malaria, the world's most widespread parasitic（寄生虫引起的）disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't （or can't） seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect （感染）. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory , Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical fades away. Other nearby ants then detect the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.
【小题1】What is the function of the first paragraph?

The most common complaint about cellphones is that people talk on them to the annoyance of people around them. But more damaging may be the cellphone’s interruption of our thoughts.
We have already entered a golden age of little white lies about our cellphones, and this is in generally a healthy, protective development. “I didn’t hear it ring” or “I didn’t realize my phone had shut off” are among the lies we tell to give ourselves space where we’re beyond reach.
The concept of being unreachable is not new – we have “Do Not Disturb” signs on the doors of hotel rooms. So why must we feel guilty when it comes to cellphones? Why must we apologize if we decide to shut off the phone for a while?
The problem is that we come from a long-established tradition of difficulty with distance communication. Until the recent mass use of cellphones, it was easy to communicate with someone next to us or a few feet away, but difficult with someone across town, the country or the globe. We came to take it for granted.
But cellphones make long-distance communication common, and endanger our time by ourselves. Now time alone, or a conversation with someone next to us which cannot be interrupted by a phone, is something to be cherished. Even cellphone devotees, myself usually included, can’t help at times wanting to throw their phones away, or curse this invention.
But we don’t and won’t, and there really is no need. That we have the right to take back our private time is a general social recognition.
In other words, we don’t have to pay too much attention to the rings of our own phones. Given the ease of making and receiving cellphone calls, if we don’t talk to the caller right now, we surely will shortly later.
A cellphone call deserves no more importance than a word from the person next to us. Though the call on my cellphone may be the one-in-a-million from Steven Spielberg–who has finally read my novel and wants to make it his next movie. But most likely it is not, and I’m better off, thinking about the idea I just had for a new story, or the slice of pizza I’ll eat for lunch.
