Sometime I call her on her 8. _____car phone, or we send e-mail to each other. 9. _____We’re really luck. There are so many ways 10. ____we can keep in touch with each other.【答案解析】1. all改为both。
指Mary和作者两个人。
2. when改为and或while。
因为两个分句没有主从关系。
而是并列关系，或者有对比或对照的含义。
3. look改为see。
因为此句意为“两个人不能经常见面(see)”。
4. 去掉keep或把we’re改为we。
因为keep是动词，若不是进行时态或被动语态，动词前不用be，但句中没有动词时必用be。
所以去掉keep或去掉are，5. telling改为tell。
tell和write是并列谓语。
6. happened改为happening。
因为这是现在进行时态。
7. phone前加the。
因为on the phone是习语，意为“用电话(交谈)”。
8. Sometime改为Sometimes。
此处表示“有时候”，而不是表示“某个不定的时候”。
9. 此行正确。
10. luck改为lucky。
用形容词作表语12。

in“在……里”表静态的位置;而into则表动态的位置，意为“进入”。
2. and改为but。
前后句之间是转折关系。
3. a改为the。
这里表特指，指要买的电视机的大小。
4. 此行正确。
5.去掉第一个for。
“把A物换成B物”的英语表达是change A for B。
文章中该句句意为“几年之后就要把小电视换成大电视”。
6. no改为not。
因为no是形容词，修饰名词，而necessary是形容词，所以要用副词not来修饰。
7. said改为says。
因为上下文都是用的一般现在时，这里指现在的思想，现在的想法。
8. they改为it。
这里指的是the big television。
9. 去掉to。
had better后接动词原形。
10. quick前加a。
make a decision意为“作出决定”。
