一、标点符号
Frederick Law Olmsted the famous landscape architect, was also a conservationist.
弗雷德里克·劳·奥姆斯特德着名的景观设计师，也是一个环保主义者。
Frederick Law Olmsted, the famous landscape architect, was also a conservationist.
弗雷德里克·劳·奥姆斯特德，着名的景观设计师，也是一个环保主义者。
解析：Frederick Law Olmsted和the famous landscape architect指代同一事物，为同位语，两个名词之间需要用逗号隔开。同位语是常见的插入成分，理解意思时可以连同逗号一同删除。
二、代词问题
Each of the trees had dropped their leaves.
每棵树都掉了叶子。
Each of the trees had dropped its leaves.
每棵树都掉了叶子。
解析：Each of the trees强调每一棵树，是单数概念而their是复数概念。所以在指代时应用its。
三、动词时态一致
I planted vegetables last year, but a late frost kills my tomatoes.
去年我种了蔬菜，但晚霜害了我的西红柿。
I planted vegetables last year, but a late frost killed my tomatoes.
去年我种了蔬菜，但晚霜冻死了我的西红柿。
解析：本句结构为but引导的并列句，前句给出planted为过去式，后句时态应保持一致，用过去式killed。
四、平行结构
The subjects Shana likes best are biology, physics, and studying French.
她较喜欢的科目是生物，物理，和学习法语。
The subjects Shana likes best are biology, physics, and French.
她较喜欢的科目是生物，物理，和法国。
解析：句中由and引导并列, 前两个被并列成分为biology/ physics 所以为了格式应保持一致，应为French。
五、句子分段
While Charlie was at the beach to enjoy the sunshine and the ocean breeze.
当查利在海滩上享受阳光和海风的时候。
While Charlie was at the beach, he enjoyed the sunshine and the ocean breeze.
当查利在海滩上时，他享受阳光和海风。
解析：由while引导的状语从句放在句首时，应用逗号和主句分隔开，标志从句结束。
六、逗号拼接
I moved to Washington when I was seven, my brother followed a year later.
我七岁的时候搬到了华盛顿，一年后我哥哥跟着我去了。
I moved to Washington when I was seven, and my brother followed a year later.
我七岁的时候搬到了华盛顿，一年后我的弟弟也跟着去了。
解析：英语句法上规定，每个句子有且仅可以有一个动词，而无论句子中有多少个逗号，本质还是一个句子。因此在较好句中出现了两个动词，是错误的。应改为and引导的并列句。
七、连接词
Thomas had been walking for miles, so he finally spotted his campsite in the distance.
托马斯走了几英里，所以他终于发现他在距离营地。
Thomas had been walking for miles when he finally spotted his campsite in the distance.
托马斯走了几英里时，他终于发现他在距离营地。
解析：he finally spotted his campsite in the distance句意上应为Thomas had been walking for miles这件事发生的时间，连接词改为when。如果两句之间用so连接，前句应为后句的结果。
八、错误改正
Leaping from the window onto the roof, Grandma was delighted by the cat’s agility.
奶奶从窗户跳到屋上，为猫的敏捷而高兴。
Leaping from the window onto the roof, the cat delighted Grandma with its agility.
猫从窗户跳到屋上，以它的敏捷使奶奶高兴。
解析：在Leaping from the window onto the roof这个部分，Leaping这个动词发出者被省略，但是只有在发出者和主句动词发出者一致时才能省略。Leaping这个动词发出者为cat而不是grandma，所以做以上更正。
九、习惯用语
Choosing where to apply about college is a difficult process for high school students.
选择在哪里申请对高中生来说是一个艰难的过程。
Choosing where to apply to college is a difficult process for high school students.
选择在哪里上对高中生来说是一个艰难的过程。
解析：apply作为不及物动词搭配to使用，意思为申请…。
十、率混淆单词
I completed all of the summer reading accept the Jane Austen novel.
我完成了所有的暑期阅读，接受了简奥斯丁的小说。
I completed all of the summer reading except the Jane Austen novel.
除了简奥斯丁的小说，我完成了所有的暑期阅读。
解析：本题考查形近词，音近词辨析。accept，动词，意思为接受。而except，介词，意思为除了…。
