What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigation, how to discover information, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one tim

e must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(实证) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正确性) of his mathematics was later tested through investigation. Einstein’s

ideas were proved to be correct. A scientist uses

many to

ols for measurements. Then the measurements are used to make mathematical calculations(计算) that may test his investigations

Most of us long for relationships in which we are loved and accepted. Our hearts’ desire is to give and receive love in relationships that make us feel that even if others disagree with what we do or say, they still love us, accept us, and appreciate what we give to the world. While it would be wonderful to have these types of relationships with all people, we know that’s hard to do. However, we can have such relationships with some others, but only when we first have them with ourselves—and, strangely, this is often the hardest relationship of all.
Do you love yourself? You may think you do, but do you really? There’s only one way to find out— by taking a close look at what you think, say, and do. You may not like some of what you find, but if you are serious about really loving yourself, you can use this insight to do some positive inner work. Here’re three ways for gaining greater personal insight for deeper love:
Listen Closely to Your Thoughts
Your thoughts will determine your actions. One thing helping you to listen to your thoughts is keeping a journal. It is not necessary for you to write in it every day, but it helps to record various insights you gain as you go about your life. Instead of using a big notebook, you might use a small notepad that you can keep in your pocket for easy access to record your thoughts as they occur to you. Whichever method you choose, what’s most important is that you write your thoughts down. It will help you know what’s in your heart.
Be Honest with Yourself
To do this, you should pay attention to your actions. Actions speak louder than words, and they always tell the truth. If you say you love your job, but your actions say otherwise, which do you think is more reliable? On the other hand, if you say you’re not good at a certain job, but your actions say otherwise, that’s also important. What do you do with this insight? You can use it to make more positive choices in your life. By being honest with yourself, you will act according to truth instead of just what you tell yourself.
Take Quiet Time to Listen to Your Inner Voice
This is similar to the first point, but it takes a step further— beyond the natural mind to the heart that cannot be seen. You may want to use your quiet time to think deeply. However you use this time, the key is to shut out all of the noise around you by focusing deep within yourself. Breathing deeply during quiet time will also help you focus. I know it’s hard to find quiet time during a particularly busy day, but it’s so important— even if it’s just 10 minutes a day and you have to hide somewhere to get it. Quiet time can really make a difference in your life.
Despite what your mind may be telling you, you can have love with no limits. The key is to unconditionally love yourself first.

In the eyes of dog lovers, the dog is man’s best friend. But for much wildlife, loose dogs may be a dangerous enemy, according to a study by a biologist from Utah State University in the US.
Based on much existing research and their own case studies, Julie Young of Utah State University and four other scientists conclude that loose dogs may represent a huge danger to wildlife, especially endangered species, by hunting down or worrying them and by spreading diseases. They also found that dogs, their worldwide numbers around 500 million, can cause more damage to wildlife and livestock(牲畜) than wolves and other enemies of these animals.
Young gave examples from the US state of Idaho, where research showed the presence of dogs reducing some deer populations. On the Navajo American Indians’ reservation in northeastern Arizona, packs of loose dogs are chasing livestock. They have killed populations of small animals such as rabbits and act as a disease carrier for rabies(狂犬病) among people and other animals, she said. Loose dogs also were to blame for distemper outbreak leading to a die-off of endangered black-footed ferrets in northwestern Wyoming in the 1980s.
The phenomenon is not just limited to US; it’s a global problen. Julie Young once studied three endangered species in central Asia: wild sheep, gazelles and antelope. The rate of injury and death to these animals by loose dogs was very high. In another case, Young found that dogs, not wolves, as originally suspected, were responsible for a large number of livestock killings in the mountainous Basque country between Spain and France.
Authors of the new study said the problem is likely to worsen as communities expand. Then how to deal with it?
Indeed, in many countries, leash(拴狗的皮带) laws permit punishment of dog owners whose pets chase wildlife. But lawbreakers are rarely punished because the police lack both people and money.
Young has low-cost solutions to the problem for dog lovers, though. They include public dog-training programs and vaccinating (预防接种) dogs against rabies and other illnesses.
小题1:. What is the main point of Julie Young’s study?

A．Many species are endangered because they are killed by loose dogs.

B．Wild dogs are immune to many diseases.

C．Wolves are still the greatest enemy of livestock.

D．Loose dogs pose a great danger to wildlife.

小题2:. Which of the following statements about loose dogs is TRUE according to the research?

A．There are around 500 million loose dogs around the world.

B．The black-footed ferrets in northwestern Wyoming were once the main food source of local loose dogs.

C．The problem caused by loose dogs is the most serious in the US.

D．People used to think that wolves, rather than loose dogs killed livestock in the Basque country.

小题3:. Which of the following is among Julie Young’s solutions to the trouble caused by loose dogs?

A．More strict leash laws

B．Public dog-training programs.

C．Vaccinating people against rabies and other illnesses.

D．More support from the police.

小题4:. What is the main point of the article?

A．A global disaster caused by loose dogs.

B．What makes the dog man’s greatest friend.

C．The problem of loose dogs and the possible solutions.

We produce 500 billion of plastic bags in a year worldwide and they are thrown away pollu

ting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.
The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.
Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.
With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.
The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.
“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

Maybe you have ever seen a cross. A cross can be a piece of jewelry or an image in
a painting. But do

you know the cross is a very popular symbol for Christmas？
It came from the story of Jesus’ death on the cross two thousand years ago in Jerusalem. Jesus was Jewish，and at that time Jewis

h people were under Roman rule. Jesus was badly punished because he declared to be the Son of God and the King of Jews. Surely，the Son of God could have saved himself from the deat

h！But the Bible says that Jesus had a reason to die that day. It was in God’s purpose that it would happen.
Christians call the day that Jesus died “Good Friday”.At first，it is hard to understand how a terrible day could ever be called good. Well，the story does not end there. Jesus died and he was buried. But three days later，Jesus was alive，and the whole world was changed.
Today，Christians everywhere remember this important time. They celebrate Easter. Easter is the day that Jesus rose from the dead. After his death on the cross，Jesus’ body was placed in a tomb. On the third day from then，God raised him from the dead. Jesus stayed on earth physically for several weeks. Many people saw him. Easter is the happiest time of year for Christians because they believe that Jesus had victory over death and evil and that now he lives with God the Father in heaven. But before celebrating Easter， Good Friday should be remembered. Jesus died a horrible and painful death. He suffered, though he did noting wrong. Christian believe that Jesus was God’s substitute(代表) for humans， because humans all do wrong. He died because of humans and he died for humans.
Christians often wear crossed around their necks of hang them in their homes because they believe it is a very important sign. The cross helps them rem

ember how much God loves them. It helps them remember how much his Son had to suffer. Seeing a cross always makes them think of Jesus’

death， and what it means.
