At first, you must understand the meaning of climate change.
It means any long-term significant change in the average weather, which may include average temperature, precipitation, wind patterns and so on. For example, Australia is experiencing rapid climate change. Since the middle of the twentieth century, Australian temperatures have risen by about average one temperature degree with an increase in the frequency of heat waves and a decrease in the numbers of frosts and cold days.
Rainfall patterns have also changed, which means that the northwest has seen an increase in rainfall over the last fifty years while much of eastern Australia and the far southwest have experienced a decline. From this example, it indicates climate change that is occurring today has sped up, and affects long-term weather. The Earth’s climate is largely affected by how much heat is stored in the atmosphere. Furthermore, the climate change is caused by dynamic process on Earth, external forces including variations in sunlight intensity, and more recently by human activities.

Can Money Buy Happiness?
Can money buy happiness? Different people have different opinions. Some think yes，while others hold the opposite.
It is true that with enough money one can buy all the things one wants，and live a life of fort and security. However，it is equally true that lack of money causes great distress. It is a mon view that "money is the root of all evil." The pursuit of money drives many people to cheat and steal. In some places there is nothing that cannot be bought with money，resulting in corrupt societies where everybody is miserable.
So，money does not necessarily mean happiness. It all depends on how it is used. If we make honest and sensible use of money，it can be a stepping-stone to happiness l Although money cannot buy happiness，it can make happiness possible if it is employed sensibly.
金钱能买来幸福吗？
金钱能买来幸福吗？不一样的人有不一样的回答。有的
诚然一个人如果有足够的钱能够买到他想要的所有物品，过上舒适稳定的生活。然而，同样缺钱往往引起巨大的忧伤。人们常常认为“金钱是万恶之源”，对金钱的追求驱使许多人去骗去偷。在某些地方，没有钱买不到的东西，导致社会的腐化堕落。
所以，金钱并不必须就意味着幸福。这取决于怎样使用金钱，如果我们诚信明智地使用金钱，它将是幸福的基石。尽管金钱买不到幸福，但它能够使幸福成为可能。
ever since the dawning of the history of mankind, there have been myriads of diversifed inventions, discoveries, and even explorations of the mysteries of the universe. in fact, the human beings are so intelligent that we have solved almost all kinds of problems we have confronted with.
however, nobody has ever made out what the word “love” really connotes, not even the most famous people such as great politicians, saints and philosophers can clarify the meaning of “love”， neither can they deal with the various affairs concerning love. love is like a huge boundless net that shrouds us all in. we can neither break away from it nor escape from it. like it or not, we are always entangled in it. it is an invisible net without any form, that shrouds in different people from different angels; it is a merciless net that upsets us or even tortures us to death. it is also a supreme net which almost no human can surpass. even if they are heroes, emperors, wise men or saints, they can do nothing but show their helplessness in its face. those who can breathe through the holes of the net should be regarded beyond commonness and vulgarity. love can bring us temporary comfort and happiness, but mostly they bring about annoyance and sufferings. maybe this is the reason why many people have seen through the illusions of the mortal world. however it is not so easy to break away from this boundless, ever-existing and indifferent net of love.
love is varied and changeable, but roughly it can be divided into three categories: family love, fraternal love and amatory love. not like monkey king who jumped out of the rocks, we were all born after mother's pregnancy of about nine months, hence we have countless relatives without any choice: parents, grand-parents, and grand-parents-in-law, uncles and aunties, brothers and sisters, etc. and once looking at the genealogical tree, we'll see no end. family love is what everyone longs for, but the warmth and support from our beloved ones are what everyone yearns for the most. but how many of us are determined to contribute to our beloved one? and how many don't expect repayment and relaxed. conscience even if they have the desire and preparation to contribute to their beloved. the distance between relatives is different and so are their expectations. but since it's very difficult to know how much we should expect, a lot of worries and distresses emerge.
dear classmates,
every one of us, rich or poor, should at least have one or two good friends. my friends will listen to me when i want to speak, will wipe my eyes when i cry, will take care of me when i am sick, and my friends will go together with me side by side through this journey of life.
as students, we could share more time with our friends. the friendship in our young hearts is pure, fresh and simple. i often feel very lucky to have a lot of good friends. especially when i had justin as one of my best friends. justin was my english teacher from the usa. i met him in 1996 when i was a student who could only speak very little english. justin was a vivid young man with a bright smile on his face, and he always had his special way to make the class active and attractive. he taught us english by telling stories, playing games, singing songs, and even dancing. i could still remember very clearly that one afternoon when we fin-ished our class, we went to some other classes to sing songs for them, just like what people do in the states on christmas eve. it was so interesting and unforgettable. justin was an excellent teacher, because he taught us not only how to study english well, but also the way to find out the beauty of the world and the way to be angels to others' lives. i know there was friendship and pure love in our hearts. facing this valuable emotion neither nationality nor age was important, the real importance lay in faith, under-standing, and care. justin is the best friend i have ever had, and i know i will cherish those days of staying together with him as the best part of my memory.
friendship is a kind of treasure in our lives. it is actually like a bottle of wine, the longer it is kept, the sweeter it will be. it is also like a cup of tea. when we are thirsty, it will be our best choice, but when we have enough time to enjoy ourselves, it is also the most fragrant drink.
