许多计划出国留学的学生在计划自己的准备工作时，都会遇到这样的问题：雅思考试成绩有多长，我应该在什么时候准备考试?

　　大多数学生在准备雅思考试时会遇到不充分的时间的问题，但是一些有特殊计划的学生会提前准备考试。此时，可能会出现一个特别令人尴尬的情况：早期获得的雅思成绩在最终申请时已经到期，他们必须接受另一项考试。更令人沮丧的是，由于以前的成就，许多学生可以放松他们的英语要求，发现他们不能在短时间内获得以前的分数。因此，了解雅思考试成绩的有效期尤为重要，这直接决定了我们何时开始准备。

　　一般来说，雅思成绩有效期为2年。换句话说，如果你计划在2019年9月出国留学，雅思成绩不能早于2017年9月。在成绩上，如果你想上培训中心攻读硕士学位，请不要在进入之前参加考试。大三;如果你是高中毕业生去国外读本科，请在进入第二年之前不要参加考试。

　　由于雅思考试的特殊性和专业性(将检查在高中时不是很重要的英语口语、，以及每个科目的难度)，我们不能指望在不回顾过去的情况下达到预期的效果。一般来说，好提前一年准备雅思。当然，具体时间取决于个人的基本水平。如果英语水平良好，那么只需将其用作主题，然后查看即可。如果英语水平较差，您可以从单词语法中补充它，然后花时间改进听，说，读，写的基础知识。最后，您熟悉雅思考试并学习考试技巧。

　　言而总之，如果你真的想出国，请尽早开始准备，不要等申请日期快截止了，你的分数尚未出来，或者申请发现他的成绩已经过期。

　　Equal and exact justice to all men, of whatever state or persuasion, religious or political; peace, commerce, and honest friendship with all nations, -- entangling alliances with none; the support of the State governments in all their rights, as the most competent administrations for our domestic concerns, and the surest bulwarks against anti-republican tendencies; the preservation of the general government in its whole constitutional vigour, as the sheet anchor of our peace at home and safety abroad; -- freedom of religion; freedom of the press; freedom of person under the protection of the habeas corpus; and trial by juries impartially selected, -- these principles form the bright constellation which has gone before us, and guided our steps through an age of revolution and reformation.

　　With all their faults, trade unions have done more for humanity than any other organization of men that ever existed. They have done more for decency, for honesty, for education, for the betterment of the race, for the developing of character in men, than any other association of men.

　　Anticipate charity by preventing poverty; assist the reduced fellow man, either by a considerable gift or a sum of money or by teaching him a trade or by putting him in the way of business so that he may earn an honest livelihood and not be forced to the dreadful alternative of holding out his hand for charity. This is the highest step and summit of charity's golden ladder.

　　- Maimonides

　　There is more to American politics than fat cats and their political friends. There are serious-minded liberals who fight the good fight on many issues, ecologically oriented politicians who remain true to their cause, and honest people of every political stripe who are not beholden to any wealthy people. But there are not enough of them, and they are often worn down by the constant pressure from lobbyists, lawyers and conventional politicians.

　　- G. William Domhoff

　　We are all travelers in the wilderness of this world, and the best we can find in our travels is an honest friend.
