母亲不是圣人

前年，母亲生日那天，我买了一件衣服，又封了一个50元的红包，骑自行车回去送给母亲。她连看都不看，就把红包放进口袋，把衣服放在桌上，不冷不热地说：“坐吧。”

我蹬自行车出了一身汗，又累又渴，还得自己倒茶喝。

正在这时，外面有小轿车的声音，那是大姐回来了。母亲好像听到命令一样，立刻迎出门。大姐一下车，母亲满脸笑容地请她进屋，问累不累。

大姐说：“妈，我不累。”大姐坐小车回来，怎么会累呢？真正累的是我，母亲却没问我。

大姐也给母亲买了一件衣服，又漂亮，又贵重。我在商场见过，最少要1000元，比我送给母亲的那件贵10倍。

大姐也给了母亲一个红包，比我的大得多。

母亲双手捧起大姐送的衣服，小心翼翼地摆在桌上最显眼的位置，再把那个大红包放在衣服上，让众人欣赏，又亲手给大姐倒了一杯茶。

母亲对大姐的亲热举动，刺痛了我的心。我一头扎进厨房里，拼命地干活，油烟呛得我流下泪来。

第二年，母亲生日时，我不再回去，只托哥带了一点礼物给母亲。

明天又是母亲的生日，我依旧买了一点礼物，托哥哥带回去。哥哥却说：“去年，你没回去，已经有些不好。明天，你再不回去，大家还以为你对妈有意见呢。”

我说：“我就是对妈有意见，她对大姐好，对我不好。大姐钱多，能讨妈欢心；我钱少，讨妈嫌。”

哥说：“不会吧，妈不是那种人。”

我委屈地说：“你没尝过那种滋味，当然不会知道。大姐回去，妈每次都到门外迎接；我回去，妈几时出门看过一眼？我穷，没法跟大姐比，但还有一点自尊心。你不帮我带东西给妈，我另找人带。”

我一气之下，把东西拿回家。刚回到家，哥哥就追来了。他买了很多东西送给我，比我买给母亲的还多。我说：“买这么多东西干什么？”哥不说话，放下东西，转身就走。

我送哥出门，一直送到楼下的马路边，哥说：“以前，我来这里，你最多送我到门口；这回破例送到马路边，是不是因为我买的东西多？”

我生气地说：“你把我当成什么人了？”

哥说：“我把你当成平凡人。平凡人都会受到名利的影响，抽到大奖会高兴，丢失钱财会伤心。这次，我送给你的东西多，你就陪我多走几步路，这很正常。平凡的母亲也会受名利影响，哪个女儿给的东西多，她就会亲热一点；哪个女儿给的东西少，她就没那么亲热。我知道，你希望妈对你和大姐一样亲热，但是，只有不受名利影响的圣人才能做得到。那种道德高深的圣人，听说500年才出一个。我们的妈不是圣人，但确实是个好母亲，你买的衣服，她一直穿在身上，袖口磨破了都舍不得丢。妈并没有嫌弃你。”

我的泪水无声地流出来，哽咽着说：“别说了，我明天回去看妈。”

母亲依然对大姐很亲热，对我没有那么亲热。但我不再怪怨她。因为我知道母亲不是圣人，大家都不是圣人。

The koala is one of Australia’s most treasured creatures, which is a lovely little creature. But now, it is in big trouble.

Affected by habitat (栖居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population,  that is worrying many scientists about the fate of the koala.

The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food.

Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala；it is up to each region to make management plans for its koala population.

The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccil1e more widely. But it’s impossible to vaccinate all wild koalas.

Another possibility would be to make vaccine distribution a routi11e part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.

While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia’s koalas.
