One possible version

This happens frequently in a teenager’s world which depends on cell phones too much. In the eyes of the youngsters’, friendship is important. But when it comes to the balance of friends and phones, kids tends to regard the latter as their bigger share.

I don’t think it is wise to neglect a devoted human friend but favor the phone, because human friends can push us on in the fierce struggle in life while phones are only our tools. So next time, when your friend falls, don’t laugh at him or her but help him or her stand up.

审题：friend和phone形成对比; laugh和cry形成矛盾。因此有话可说。一般而论，应该选择批驳重电话而轻友谊的信念，即不要重物质而轻友情。

写作技巧

首先要对材料进行阐释，此时不宜抄袭原材料，而是改写材料。其次是对这中选择进行选择性论述。最后提出建议。遣词造句尽量使用自己熟悉的词句。特别是要尽量使用较为复杂的句型，如状语从句，定语从句等。
