Nowadays, house husband has become a hot phenomenon in modern society. As

we all know that no matter what country, it’s a tradition that men play a core

role in family who always take the burden to earn money to support their family.

But things are kind of different as society develops, more and more men are

beginning to take over housework while women go out from house. In my point of

view, I think this is not a big deal.

In the first place, house husband may be a shame title for men, but when it

comes to money, there is no room for reputation. As society develops, the life

standard are rising, and everything for living is much expensive than before, if

couples want to guarantee their life quality, then they should let the one who

earn better to work, although the one is female.

In the second place, it’s fine for women to support family as long as they

earn better than men. In the past, women always were treated very badly, and

they got no rights to be educated, to work. In some countries, they can’t even

show their face to others. A traditional female role is to stay at home, taking

care of children and do all of the housework. But now, lots of women have a good

job, so that they totally have the ability to be the economic backbone.

Therefore, in order to take good care of family, men are likely to stay at home

to do housework. I don’t think it’s a shame for men, because no matter what you

do, as long as you do it well, you are successful.

To sum up, people should change their opinion about core role of a family.

It’s acceptable for women to support the family, and there is no shame for men

to do the housework. As long as you remember life quality comes first.

The air we breathe is so freely available that we take it for granted. Yet without it we could not survive more than a few minutes. For the most part, the same air is available to everyone, and everyone needs it. Some people use the air to sustain them while they sit around and feel sorry for themselves. Others breathe in the air and use the energy it provides to make a magnificent life for themselves.

Opportunity is the same way. It is everywhere. Opportunity is so freely available that we take it for granted. Yet opportunity alone is not enough to create success. Opportunity must be seized and acted upon in order to have value. So many people are so anxious to "get in" on a "ground floor opportunity", as if the opportunity will do all the work. Thats impossible.

Just as you need air to breathe, you need opportunity to succeed. It takes more than just breathing in the fresh air of opportunity, however. You must make use of that opportunity. Thats not up to the opportunity. Thats up to you. It doesnt matter what "floor" the opportunity is on. What matters is what you do with it.

The joyous Mid-Autumn Festival was celebrated on the fifteenth day of the

eighth moon, around the time of the autumn equinox(秋分). Many referred to it

simply as the "Fifteenth of the Eighth Moon".

This day was also considered as a harvest festival since fruits, vegetables

and grain had been harvested by this time and food was abundant. Food offerings

were placed on an altar set up in the courtyard. Apples, pears, peaches, grapes,

pomegranates(石榴), melons, oranges and pomelos(柚子) might be seen. Special foods

for the festival included moon cakes, cooked taro(芋头)and water caltrope(菱角), a

type of water chestnut resembling black buffalo horns. Some people insisted that

cooked taro be included because at the time of creation, taro was the first food

discovered at night in the moonlight. Of all these foods, it could not be

omitted from the Mid-Autumn Festival.

篇8:节约资源,保护家园

全文共 1173 字

环保,是每个人应尽的义务。环境保护,可以使地球的温室效应大大降低,可以使濒危物种不惨遭灭绝的厄运,可以使疾病发生的几率大大降低,还可以使城市变得更加干净、美丽……因此,请大家一起来环保,来保护我们赖以生存的家园——地球。

环保,对于我们很重要。因此,我家也正在环保。塑料,这种韧性强、强度高的不可再生材料,在各个领域都有广泛的应用。可是,有多少人知道,塑料要经过200年左右才会降解,过多会形成“白色污染”呀!因此,我家到集市买菜时,都是用上次买菜用的塑料袋去继续使用,尽可能多地反复使用。如果大家都这样做,塑料对环境的污染就可以大大降低。

再说说电池。电池,是一种蓄电量较低的储电装置。并且大多电池不但不能充电,而且含有汞、铅、镍、镉等重金属。一节电池就可以污染一个人一生的用水——约500立方米。这是一个多么庞大的数字呀!所以,我们家只要有电用光并且不可以再充电的电池,就会把他们用一个瓶子装起来 ,让电池不再污染环境。

水是生命之源,如果没有了水,就没有生命的存在。所以,我们应该节约用水。有些人会说:“地球上的水多着呢,何必那么节约呢?”其实,你错了,如果人们毫无节制的用水,可能在将来就没有了生命的存在,并且就不再可能有生命诞生了!所以,我家也在节约用水。我们把淘米水用来洗菜、浇花;洗脸、脚用的水用来洗袜子、冲厕所、浇花;我家有一个浴盆,由于洗澡用的水比淋浴要多,所以我们经常将洗澡用的水用来先洗衣服,再用洗衣服的水去冲厕所、拖地。这样,不仅节省了水费,而且节约了许多水。所以,我建议大家反复利用水,使水的作用充分发挥出来。

不仅我家在做环保小事,就连我也自主做起环保小事。

纸,他是全世界用得最广泛的办公用品。因为它轻,所以深受人们的青睐。可是,纸却大多用木材通过化学物质氢氧化钠造成纸浆,但是会产生许许多多的污水呀!然后把纸浆滤在细纱网上晾成纸。最后,还要经过多重处理,使纸变得更加平滑、洁白。有的人会说:“纸不是可以降解的吗?对环境没有污染。”那你就大错特错了:纸在生产过程中会产生许多污水,而浪费没有使用过的纸,不就等于浪费木材、故意制造污水吗?所以,每当一个学期结束,我就会将作业本找出来,将没有使用过的空白页订起来制作成一本数学草稿本。这样,没有使用过的纸就不会造成浪费了。所以,我建议大家充分使用纸张,这样就不会造成资源浪费。

在生活中,随处可以看见花草树木。可是,有些人故意去攀折树木。但是,你想过没有:树的叶子可以吸收二氧化碳,释放出氧气。而如果人人都去折树木的叶子树木释放出来的氧气不就一天比一天少了吗?所以,我们一定要爱护花草树木……

在环境保护中,有很多事情都需要我们去做。所以“播种绿色,收获健康”就可以是世界变得更加和谐美好!所以,我呼吁同学们:从现在开始,从我做起,为了保护美丽的家园携起手来,为环境保护作出应有的贡献

Peer pressure means the influence given by a group of people around you,

such as, parents, friends, classmates, teachers and so on. Their influence will

affect your attitude, behavior, conception or decision. As every side has two

sides, this influence also has two sides. Let me explain my reasons.

For one thing, influence of peer pressure has positive effect. It depends

on the specific thing. Sometimes, the influence of pressure will promote me get

progress. For instance, my deskmate does well in one math exam, while I fall far

behind her. As we are deskmates, i can’t let others look down on me. So i will

take her as my good example to fight. And then next time, I can get a good mark

by my effort. Take my parents as another example, they like clean. They don’t

have the habit to throw rubbish at will. I won’t have this habit either living

with them.

For another, influence of peer pressure has negative effect. Sometimes the

influence will be bad. For example, if my friends ask me to skip class to watch

a basketball match with them, i go with them, even i don’t have that thought

before. And one of my friends has gone through a lot, he always try to convince

me that money is very important. As time passes, i may change my conception.

In summary, the influence of peer pressure has positive and negative sides.

We have to advocate the good side and avoid the negative. We have to be clear

about what is right and what is wrong and firm our position.

More and more college students, in recent years, are finding it difficult

to find jobs. This may sound strange since college students used to be the "most

favored" people in society. They have received a higher education, hence they

are more intelligent, knowledgeable than their counterparts who failed to attend

college. But chances are that some of them can hardly find jobs after graduating

from colleges.

There are two reasons that account for this strange phenomenon. One is that

some college students cannot come to terms with themselves and with the world

around them. They pursue too high goals and are too particular about such

factors as working conditions, salary, and so on. Therefore, they are reluctant

to accept the job when they are offered to them. Another reason is that the

majors some students pursue do not match with the demands of the job market. As

a result, they canonly sit and miss opportunities.

To solve this problem, I think college students should know their own

strengths and weaknesses and have the right attitude towards themselves and the

job vacancies. In addition, they should not attach too much importance to

material aspects of the job. They should put priority to their future

development and their contributions to society in stead. Furthermore, they

should think of receiving some further training to meet the demands of

society.

大街上,一张张看完的报纸、用过的白纸,一罐罐喝完的易拉罐随地可见;学校里,厕所的水龙头没有关紧,一滴滴水随着时间的流逝,慢慢的积少成多。大家都在操场上,空无一人的课室里亮着所有的灯;家里,多开了不必要的灯,洗澡时没有节约用水等。而对此,有些人不是那么在意,他们认为滴一点水,多开几盏灯,丢弃一两张纸都没有关系。但是大家因该明白积少成多这个道理,如果每个人都这样想,那我们该损失多少资源。大家也因该明白地球的资源也不是无限的,大家要节约使用。

当然,节约资源,也不是一朝一夕的事情,要从小开始养成。

妈妈从小教育我要节约,不要浪费。洗菜用的水我会把它们拿去浇花,如果用不完,就把它们倒到厕所的桶里;用过的废纸我会把它们订成一本本子做我的草稿本。报纸呢,看完后我会把它们放置好,如果需要擦窗就把它们拿出来用;洗脸时,我会把水倒在盆子里,听说这样可以节约水,而且方便把水倒在厕所的桶里;出门时,我总会带一个环保袋,绝不用塑料胶袋。相信大家都明白,塑料胶袋即不环保又不卫生;而那些喝完的饮料罐、不用的纸皮等废物,我会储存好,有空时拿出来拼装,把它们制作成科技作品。

With the development of Internet, more and more people tend to shop on the

Internet. Online shopping has provided some benefits for us, but it also has

some disadvantages at the same time.

For one thing, online shopping has brought some convenience for consumers.

Instead of going one shop to another, people can choose and buy all kinds of

commodities they like as long as they click the mouse gently. This is not only a

better choice for the old who do not have enough energy to go outside but also a

great convenience for those who have no time to go shopping in person. In

addition, consumers have more choices and can do some comparison when they are

shopping on the Internet. They can glance over various commodities in all

shapes, sizes and colors and decided to buy or not. Furthermore, online shopping

has made a great contribution to the development of express delivery

industry.

However, for another, shopping on the Internet also has some shortcomings.

Firstly, those who shop on the Internet can’t try the goods before they buy.

Sometimes, the real goods are not the same as the goods they see on the

Internet. Secondly, some shops on the Internet are dishonest and they would not

deliver the goods after paying. And if this situation happens, the consumers

would find nowhere to complain and never pull out the money any longer.

Therefore, we should pay more attention when shopping on the Internet.

Competing teams row their boats forward to a drumbeat racing to reach the finish end first.

The boat races during the Dragon Boat Festival are traditional customs to attempts to rescue the patriotic poet Chu Yuan.

Chu Yuan drowned on the fifth day of the fifth lunar month in 277 B.C. Chinese citizens now throw bamboo leaves filled with cooked rice into the water.

Therefore the fish could eat the rice rather than the hero poet. This later on turned into the custom of eating tzungtzu and rice dumplings.

All the people want to stay in good health. Health is better than wealth.

It is true that health is the first step to success. Imagine this, if you’re

sick, all you can do is to stay in bed and do nothing at all, how can you chase

after your dreams?But if you’re in good health, you can overcome the adversities

you ever encounter and make your dreams come true. Since health is so important

for everybody, how can we maintain and enhance our health? There are some useful

suggestions:

rise makes a healthy man. Do not stay up late. Some people love to play cell

phones games or reading electronic-books before sleep, this can be bad for the

health. We should remember to turn off the phones before sleep. Second, don’t be

too particular about food. Try to eat more fruit and vegetables and less sugars

and soft drinks. If you want to eat a bar of chocolate, eat an apple instead. If

you want to drink milk tea or coffee, drink water instead. Don’t eat too much

meat in one week. Last but not least, we should do exercise everyday. There are

many exercises for us to choose. Such as, swimming, jogging, square dancing,

playing badminton and so on. Doing exercise can increase the circulation of

blood and enhance our immune system. The one who in better immune system, the

less disease he will have.

getting sick. Try to sleep earlier, eat more fruit and vegetable, drink more

water, and do exercise everyday. You will realize that it’s not that hard to

stay in good health.

Saving Water

The world is not only hungry,but also thirsty for water. This may seem strange to you, since nearly 75 % of the earths surface is covered with water. But about 97% of this huge amount is sea water, or salt water. Man can only drink and use the other 3% -- the fresh water that comes from rivers, lakes,underground, and other sources. And we cannot even use all of that, because some of it is in the form of icebergs and glaciers. Even worse, some of it has been polluted.

However, as things stand today, this small amount of fresh water, which is constantly being replaced by rainfall, is still enough for us. But our need for water is increasing rapidly-- almost day by day. Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on. A limited water supply would have a bad effect on agriculture and industry. Let me give you just one small exampie of how necessary water is to industry. Did you know that to produce a single ton of steel, it takes about 91, 000 liters of water?

We all have to learn how to stop wasting our precious water. One of the first steps we should take is to develop ways of reusing it. Experiments have already been done in this field, but only on a small scale. For us, the systems are as important as the spacecraft.

节约用水

我们的世界不仅饥饿,而且因为缺水而干渴。对你来说这可能似乎奇怪:因为我们的地球表面75%由水覆盖着。但是,这巨大的数量中97%是海水、或咸水。只有剩下3%

的来自河流、湖泊、地下,和其他来源的淡水供人们饮用、使用。即使如此,这3%的水源我们也不能够完全使用,因为有些淡水是以冰山或冰河的形式存在。更糟糕的是,一些水源已遭受了污染。

然而,尽管按现状看来,这些少量的淡水即使时常转化成雨水的形式,对我们来说,也仍然够用。可是我们对水的需求却日益迅速增长。我们只有现在采取措施解决这一问

题才能避免未来世界范围内的严重水资源缺乏。限量供水会对农业和工业产生不良的影响。我们举个小小的事例就能证明水对工业的必要性。每生产一吨钢材就要消耗91,000升水,你知道吗?

我们必须杜绝对宝贵水资源的浪费。我们应该采取的第一步就是要发展水再利用的方法。该领域的实验已在进行,但是仅是小规模地进行。水资源再利用系统的重要性

对我们而言,与空间站不相上下。
