Nearly 200 countries have passed an important historic agreement to fight global climate change.The agreement came after twelve days of talks between the leaders at the 21st Conference in Paris,France.

  As part of the Paris Agreement, countries said they’d cut down on pollution. However，according to the terms of the deal, countries that don’t do this won’t be fined. Instead, the document is meant to show governments around the world are willing to work together to fight global warming.

World leaders have met many times to discuss climate change. But, the 21st Conference of Paris, or COP21, which began on November 30, was the first time they agreed on a global, legal pact (协定）.

  Before the conference, each nation was asked to create plans on how to reach the shared goal. The pact that was passed allows countries to decide the best way to cut down their gas pollution. Every five years, nations must look at the work they’ve done and submit new plans on how they’ll improve over the next five years.

  In the pact,the countries promise to limit the amount of greenhouse gases emitted (排放）by human activity to the levels that trees, soil and oceans can absorb naturally. It urges countries to spend trillions of dollars on creating new energy sources. It also requires countries to raise at least $ 100 billion each year to help developing countries

   However, critics of the pact say it doesn’t include specifics about how the plan will be carried out and how improvements will be measured. The pact does include one large, specific goal： how countries will aim to keep global temperatures from rising more than 3. 6°F (2°C) by 2100.

However, the agreement is considered by many world leaders to be a major victory. The UN has been working more than two decades to convince governments to work together to reduce man-made emissions.

  “History will remember this day,” UN Secretary General Ban Ki-moon said. “The Paris Agreement on climate change is a monumental success for the planet and its people. ”

It was just over five years ago that we were waiting with decreased breath for Apple’s table!computer(平板电脑)．The company delivered．released its new creation，and set about redefining what a “tablet”could be．Remember?Table computers used to be heavy，folding laptops that ran Microsoft Windows and much terrible sofeware．The release of the new creation helped redraw that too1 in consumers’minds．No．this wasn’t the weighty thick of steel powered by UPS(不间断电源)any more；this was the future of the computer．

    I was always doubtful about them．Sure．they seemed wonderful and light and perfect for bed-based computing．But they weren’t the right type for a lot of the ways I used a computer．They were great for a meeting but less so for my desk．When I needed to finish a report carefully or design a page，I needed the accuracy of my otherwise anachronistic(过时的) mouse．And，most important of all，I already owned a laptop．like most people．Buying another computer seemed more of a“nice to have”than a“must have．”

    New figures from IDC，the market research firm，suggest that we’ve reached an upper limit for the modem tablet computer．According to the firm，shipments(发货)of the tool in the second quarter of this year dropped 7％worldwide compared to the same time last year．Apple and Samsung，the market leaders(41％ combined market share),each experienced a drop year over year as competitors like LG and Huawei exploded．

    But the overall market is minishing，just five years after it appeared．For good reason：Laptops continue to decrease—have you seen the latest Macbook?——and smartphones continue to grow,even as both get lighter and longer-lasting in terms of battery life．Tablets．stuck in the middle,still have their place．But the meaning of that place is decreasing.Not very encouraging for a young，new computing type．

    Are tablets dead?I don’t think so．They remain important to specialized uses，from hospitals to delivery trucks to sales meetings．Hundreds of millions continue to be sold every year．And some of their best qualities have been absorbed by the latest generation of laptops．(What is the new Macbook if not a touchscreen-lacking iPad with a keyboard and IOS X，Apple’s desktop operating system?) But from the looks of these numbers．tablets have an identity problem that can’t be ignored．

As the global financial crisis hits the economy, itˈs tough finding a job—especially if youˈre competing with thousands of other hopeful students. Sometimes you get the interview, but donˈt quite seem to land the job because you donˈt have related experience. Donˈt despair! Here are a few tips that might give you an edge.

★Get connected to your network and try to expand it. Talk to friends, family and acquaintances. Let everyone know you are looking for a job.

★Prepare your resume (个人简历) carefully and be sure itˈs perfect. Have someone else read it over for typos (打字错误) and grammatical errors. Get professional help. Itˈs worth the money to present yourself well. If money is tight, read books on resume writing from your public library or search for free help on the Internet.

★When you apply for a job, be sure you match and list any skills listed on the posting with the skills you have. If you get an interview, be sure to describe those skills thoroughly. Just having the skills is not enough. Expressing your abilities well can make all the difference in getting the job.

★Research typical interview questions and practice interviewing. Be well prepared for every interview.

★Donˈt be afraid to accept a position for which you are overqualified—if thereˈs room for advancements. Many great job advancements come from first doing well at an entry­level position. If you have the right skills and attitude, it wonˈt be long before youˈre in the job you want.

★Volunteer for a few weeks in your field of study to gain experience if you feel your resume needs an improvement.

★When deciding what to wear for an interview, think about the position level and the dress code of the organization.

★Use every tool available to you. For example, this site has many job links for your use.

Good luck!

  A new United Nations report shows that fish farming may soon be the world’s most important provider of fish. The Food and Agriculture Organization says fish farming is growing at a rate of 6.6 percent a year.

         Fish farming now produces forty-six percent of the world’s supply of fish. That represents a forty-three percent increase from 2006. The report also said fish farming earned more money in 2008 than traditional fisheries.

         In fish farming, fish are raised in tanks or small bodies of water called ponds. They are also raised in cages or nets in oceans, lakes and rivers. The report says increased fish farming has helped people around the world eat record amounts of fish. The FAO says each person ate an average of almost seventeen kilograms of fish last year.

         However, the FAO says the current(当前的) yearly wild-fish harvest of ninety million tons shows no improvement. Decreasing numbers of fish and stronger catch limits have reduced the possibilities for catching wild fish. The FAO report says about thirty-two percent of world supplies are overfished. It says these supplies of fish need to be rebuilt at once.

         Some scientists have criticized fish farming. They say the nets and cages permit fish diseases and pests to spread. Some fish farming critics doubt whether fish farming can keep growing at the current rate. But Wally Stevens of the trade group Global Aquaculture Alliance says the industry must continue developing to feed growing populations. Mr. Stevens says a one hundred percent increase in fish farming over ten years is necessary to keep providing for people at the current level. He notes that fish farming creates jobs and wealth, especially for people in coastal areas of China.
