剑桥考试每年3月和9月举办，包括听、说、读写三部分。考试成绩盾牌为准，每个部分都是5个盾，人们常说的满盾就是把15个盾全部获得。不过满盾的获得并不是说一道题都不能错，而是在每个部分中可以错一两道题。

剑桥少儿英语分为一级、二级、三级共三个级别。

一级适合6-8岁的儿童，需要经过大约240学时的英语学习，掌握近400个词汇，能够简单描述家庭、学校、朋友、自己、体育运动和业余活动等主题，涉及年龄、外貌、颜色等概念，二级适合8-11岁的儿童，经过大约420学时的英语学习，掌握约600个词汇，具体描述的概念扩展到天气、健康、环境、动作、职责等，三级适合9-12岁，经过大约600学时的英语学习，掌握1000个词汇，能够运用学过的词汇讲述自己生活中的人和事，词汇量可达到教育部规定的初中毕业要求。

1、The children were running on the playground as fast as they can.

改：can-could

解释：主句是过去进行时，从句也应该是过去时，保持一致。

2、Since her husband had died, so she had to support her family.

改：把so去掉。

解释：since表示原因，不需要so再来表示结果。两个词不能同时用在一个句子中。

3、He won't go out until his mother will come.

改：will come-comes

解释：主句是一般将来时，until引导的时间状语从句用现在时表示将来，改为第三人称单数。

改：very-so

解释：so...that，如此……以至于。

5、Tom had gone out as soon as his mother got home.
