I have arrived at USA,and now I am in the jet lag. 这句话涉及的语法点有现在完成时和一般现在时。现在完成时：主语+have/has+动词的过去分词 一般现在时:主语+动词原形+其它，而倒时差为jet lag。 例句：It's a good idea to spend the first night of your holiday sleeping off the jet lag 把假期的第一个晚上用来睡觉倒时差是个不错的主意。 综上，此句应翻译为：I have arrivited at USA,and now I am in the jet lag. 扩展资料： 1、现在完成时不能单独与准确时间状语连用，（如表示过去的时间状语） 如yesterday(morning、afternoon),last(morning、afternoon）等，除非与for,since连用. 2、现在完成时往往同表示不确定的过去时间状语连用 如already（肯定句中），yet（否定，疑问，句末），just,before,recently,still,lately,ever等： He has already obtained a scholarship.他已经获得了一份奖学金。 3、现在完成时态经常与表示频率的时间状语连用， 如often,sometimes,ever,never,twice,on several occasion等： I have never heard Bunny say anything against her.我从来没有听到Bunny说她的坏话。 参考资料：百度百科-现在完成时 参考资料：百度百科-一般现在时

自发性：在市场经济中，商品的生产者和经营者，在价值规律的自发调节下自发进行的。例如：为了自身的利益，有的工厂大量排放废气、废水，甚至制假售假；有的人为了自身的利益，剽窃他人的智力成果，对他人辛辛苦苦开发出来的软件进行盗版。 盲目性：由于人们不可能完全掌握市场各方面的信息，也无法控制经济变化的趋势，他们的决策会带有一定的盲目性。当某种商品的生产有利可图时，往往一哄而上；反之，则一哄而退。例如：不少农民“跟风种地”，去年市场什么品种走俏，今年就种什么品种，结果往往事与愿违。他们之所以不能取得预期的经济效益，是市场经济的盲目性导致的。 滞后性：市场虽有及时、灵敏的特点，但它不能反映出供需的长期趋势。而是有一定的时间差，是一种事后调节。例如：一个村子都在种稻米。某一年，张三家种西瓜，获利是其他人种稻米的3倍。全村人看到后就向张三学习，一起种西瓜。第二年的时候西瓜太多，市场消化能力有限。西瓜滞销，贱卖也卖不出，留在家里腐烂。 市场调节是什么呢？ 市场调节是由价值规律自发地调节经济的运行。即由供求变化引起价格涨落，调节社会劳动力和生产资料在各个部门的分配，调节生产和流通。符合商品经济的客观要求，能够比较合理地进行资源配置，使企业的生产经营与市场直接联系起来，促进竞争。但市场调节具有盲目性一面，因而在社会主义条件下，有必要加强宏观调控。 由市场供求关系的变化引起的价格变动对社会经济活动进行的调节。

必修5 Unit 3 FIRST IMPRESSIONS Spacemall: [email protected] 15/11/3008 (Earthtime) Dear Mum and Dad, I still cannot believe that I am taking up this prize that I won last year. I have to remind myself constantly that I am really in AD 3008. Worried about the journey, I was unsettled for the first few days. As a result, I suffered from “Time lag”. This is similar to the “jet lag” you get from flying, but it seems you keep getting flashbacks from your previous time period. So I was very nervous and uncertain at first. However, my friend and guide, Wang Ping, was very understanding and gave me some green tablets which helped a lot. Well-known for their expertise, his parents' company, called "Future Tours", transported me safely into the future in a time capsule. I can still remember the moment when the space stewardess called us all to the capsule and we climbed in through a small opening. The seats were comfortable and after a calming drink, we felt sleepy and closed our eyes. The capsule began swinging gently sideways as we lay relaxed and dreaming. A few minutes later, the journey was completed and we had arrived. I was still on the earth but one thousand years in the future. What would I find? At first my new surroundings were difficult to tolerate. The air seemed thin, as though its combination of gases had little oxygen left. Hit by a lack of fresh air, my head ached. Just as I tried to make the necessary adjustment to this new situation, Wang Ping appeared. "Put on this mask," he advised. "It'll make you feel much better." He handed it to me and immediately hurried me through to a small room nearby for a rest. I felt better in no time. Soon I was back on my feet again and following him to collect a hovering carriage driven by computer. These carriages float above the ground and by bending or pressing down in your seat, you can move swiftly. Wang Ping fastened my safety belt and showed me how to use it. Soon I could fly as fast as him. However, I lost sight of Wang Ping when we reached what looked like a large market because of too many carriages flying by in all directions. He was swept up into the centre of them. Just at that moment I had a "time lag" flashback and saw the area again as it had been in the year AD 2008. I realized that I had been transported into the future of what was still my hometown! Then I caught sight of Wang Ping again and flew after him. Arriving at a strange-looking house, he showed me into a large, bright clean room. It had a green wall, a brown floor and soft lighting. Suddenly the wall moved - it was made of trees! I found later that their leaves provided the room with much-needed oxygen. Then Wang Ping flashed a switch on a computer screen, and a table and some chairs rose from under the floor as if by magic. "Why not sit down and eat a little?" he said. "You may find this difficult as it is your first time travel trip. Just relax, since there is nothing planned on the timetable today. Tomorrow you'll be ready for some visits." Having said this, he spread some food on the table, and produced a bed from the floor. After he left, I had a brief meal and a hot bath. Exhausted, I slid into bed and fell fast asleep. More news later from your loving son, Li Qiang
