网络解决方案如图4-1所示。该网络原先使用的是国外品牌的交换机，随着网络规模的扩大，增添了部分国产品牌的交换机，交换机1至交换机5均是国产10M/100M自适应交换机，交换机6和交换机7是第三层交换机。
该网络在运营过程中曾出现了下列故障：
故障1
使用“网络故障一点通”测试新建密集小区用户和三层交换机6之间的最大吞吐量，发现这些用户带宽都不超过10Mb/s。
使用“型网络万用表”串联在三层交换机6和交换机4之间，测试数秒钟后，发现它们之间的传输速率也是10Mb/s。
故障2
故障现象：VIP小区用户不能上网，但能Ping通路由器地址。
分析：由于VIP小区用户配置的是静态IP地址，而且处在同一网段，共用路由器上的一个地址作为网关地址。用户能Ping通路由器，说明从用户到路由器间的路径是通的，因此需重点检查路由器。
操作过程如下：
首先，在路由器上，观察接口状态，未见异常。
然后，用show ip route观察 (1) ，未见异常。
最后，再用show arp观察 (2) 表，发现路由器的MAC地址与工作人员以前保存在该表中的MAC地址不同，而是VIP小区中某个用户的MAC地址。
造成故障1的原因是什么？如何解决？

Directions: Translate the following text into Chinese.
When I am in a serious humor, I very often walk by myself in Westminster Abbey; where the gloominess of the place, and the use which it is applied, with the solemnity of the building, and the condition of the people who lie in it, are apt to fill the mind with a kind of melancholy, or rather thoughtfulness, that is not disagreeable I yesterday passed a whole afternoon in the churchyard, the cloisters, and the church, amusing myself with the tombstones and inscriptions that I met with in those several regions of the dead. Most of them recorded nothing else of ~e buried person, but that he was born upon one day, and died upon another; the whole history of his life being comprehended in those two circumstances, that are common to all mankind could not but look upon these registers of existence, whether of brass or marble, as a kind of satire upon the departed persons; who had left no other memorial of them, but that they were horn and that they died.

Sunglasses can help your eyes in two important ways. They improve the normal light filtering abilities of your eyes and they protect against the sun's damaging rays. Good sun glasses will reduce strong light, filter out(滤除)99 to 100 percent of ultraviolet(UV)rays(紫外线) , provide visual protection, comfortable and not distort colors.
The UV rays in sunlight can damage your eyes, some of the damage can be immediate while some occurs over a life time of exposure.
Good quality sunglasses help to protect your eyes from harmful UV radiation. It is generally agreed that the less UV rays that get through, the better. Experts recommend that to protect your eyes from harmful rays, your sunglasses should block 99 to 100 percent of both UV-A and UV-B rays. Furthermore, lenses should block at least 70 percent of visible light but even this can vary with the situation. In areas where light is strong such as at the beach or on snow, as little as 10 to 15 percent of transmission is better.
Selecting the right sunglasses is an important choice to protect your eyes and your vision(视力) . When selecting sunglasses for children, keep the following suggestions in mind.
Check the sunglasses often to make sure they fit well and are not damaged. Children often don't tell about their vision even when there's a problem, so a regular check may be necessary.
Select sunglasses that suit children's active lifestyles. The glasses should be impact (冲撞) resistant, and the frames should be bendable, unbreakable. Children's sunglasses should never be made of glass, unless required by their eye doctors.
The lenses should be large enough to protect the eyes from most angles (above, below and either side) and to block light that gets in around the frames. The sunglasses should fit the child's nose, to reduce the amount of sunlight that enters the eyes.
Sunglasses can protect our eyes and be comfortable at the same time by______.
