• ### CHECK GRAMMAR...PLZ

As time progresses, people are continuing todevelop new technology and devices for people to use. They make life easier. Ithink the motor vehicle is a good example of this. Vehicles are of many types,such as the bus, cab, car, train. I think the car is the best of all vehicles.There are three things that prove my thesis is correct. Firstly, I can drive mycar everywhere that I like. Secondly, I regard sitting in my own car as morecomfortable than sitting in a public vehicle. Lastly, I believe that publictransport fees are more expensive than the gasoline cost. Let me explain themone by one.First of all, I can drive my car everywherethat I like. As public transport cannot take me to everywhere, it is veryinconvenient for me. People may say that I can take a taxi, but it is veryexpensive for me to do so. If I take a taxi, I need to pay about \$20 for oneway. Moreover, when I feel bored at midnight, I can take a joyride. There willnot be any public transport services at midnight. Therefore, I believe aprivate car is the best.Secondly, I regard sitting in my own car asmore comfortable and safe than sitting in public transportation. The seat in mycar is wider than public transport seating. There is a excellent safetyequipment in my car. For example, there are seat belts in my car. There is asafety bubble cushion that prevents my head getting hurt in an accident. On theother hand, there are no seat belts on the bus. The seats on the bus are verytight. I do not have enough space to move. Therefore, I believe a private caris the best.

As we are human being,we must tried to guide by our conscience when we ae facing a question.

There was a question that I need to guide my conscience.That is I don't want to go to scholll in recent days.As you know that it is so cold in Winter time and my homestay is far away from the school and also the bus stop.Every day morning,I feel very cold and I don't want to leave my bed,I just want to stay there and sleep .

In this moment,my angle and deathful will pop up.'Cherry,you must wake up,if you don't go to school,ypu will miss a lot of lessons ,your parent will punish you and your teacher will think that you are a bad student because of this,'my angel said.But my deathful must said Cherry,don't worry.Just one day you don't go to school,you won't miss a lot of things.You want to sleep more,right?Then just sleep.

Finally, I woke up and I went to school.As I don't want to miss some lessons and I will in trouble if my parents know that.I started thinking why I have this idea.I have never tried to think "don't go to school',but why I have this idea,beacuse of the weather.I think I am too bad,as if you are a student ,you must never have this kinds of ideas.I promise myself I must go to school everyday.

• ### chemistry一問

1)For elements in the main groups:

-Period number of an element

=number of occupied electron shells in an atom of the element

-Group number of an element

=number of outermost shell electrons in an atom of the element

2)Elements within the same group of the Periodic Table have the same number of outermost shell electrons in their atoms,therefore they have similar chemical properties.However,there is a gradual change in reactivity down a group.

3)Chemical properties of an unfamiliar element can be predicted from its position in the Periodic Table.

【明報專訊】4名三鹿毒奶粉案受害嬰幼兒家長，入稟本港小額錢債審裁處，向三鹿集團第2大股東、新西蘭恆天然集團在香港的分公司索償，家長能否勝訴，還待法庭裁決。此案在三鹿受害者尋求公義過程中別具意義，案件若成功索償，香港可能成為內地人士維權新途徑，所以，案件的發展值得關注。

三鹿毒奶粉事件在2008年9月揭發，奶粉中的三聚氰胺成分過高，導致嬰幼兒腎結石，小便時痛苦不堪。事件揭發三鹿當局和地方官員，其實早知奶粉有問題，卻一直隱瞞事態，而省和國家相關部門監管不力。根據衛生部統計，三鹿毒奶粉受害嬰幼兒近30萬人，6名嬰幼兒死亡。內地當局以「快偵快審快判」處理，拘捕奶農，其中兩名被判死刑並已執行，拘控三鹿集團多名高層，包括董事長田文華等，判處田文華終身監禁，而三鹿集團所在地石家莊多名官員，因此丟官。

官方視三鹿毒奶已結案

受害家長鍥而不捨維權

至於賠償，2008年底官方公布死亡賠償人民幣20萬元，重症3萬元，普通症狀2000元，大批家長不滿，從那時候開始，不斷採取行動爭取權益，要求更多賠償。從事態發展看來，官方認為三鹿毒奶粉事件已經終結，連三鹿集團已於去年11月完成破產程序，但是受害嬰幼兒家長鍥而不捨爭取權益，據已知情 ，在當局打壓之下，家長們的維權之路極其艱困。

三鹿毒奶粉受害嬰幼兒遍佈全國，先後有不少家長在各地入稟法院，控告三鹿集團，但是法院都消極處理或不予受理。法律界方面，事件揭發之初，三鹿集團所在地的河北省當局第一時間召集全省律師開會，阻止當地律師代理受害者訴訟。全國22個省市區逾百名律師，透過「公共利益同盟」給毒奶粉受害者提供法律幫助，這個組織所沾手維權事務，毒奶粉事件是其一，現在組織幾經當局打壓，已經解散，其法人代表許志永律師一度被拘押。

至於受害嬰幼兒家長之一的趙連海，積極聯繫其他家長維權，組成「結石寶寶之家」，他的處境就更慘了。趙連海去年11月被拘押，今年3月底以「尋釁滋事」罪名在北京受審，迄今未宣判；若罪成，最高可判囚3年。當日趙連海受審，他的妻子不能到法庭旁聽，5歲兒子在法庭外哭叫爸爸的情狀，使人動容。我們詳述毒奶粉受害家長維權行動之艱辛，只是要指出，他們若在內地繼續抗爭，趙連海的遭遇將不是孤例。所以，他們這次來港入稟審裁處索償，是另闢蹊徑。

家長入稟控告新西蘭恆天然集團在香港的分公司，要求賠償，主要是恆天然擁有三鹿43%股權，而新西蘭總理克拉克曾透露2008年8月初恆天然集團得知三鹿奶粉有問題，但是地方當局阻撓回收，克拉克9月初得知事態，直接與北京中央政府接觸，事件才揭發。到9月11日，內地才宣布回收三鹿奶粉。4名家長基於這種情，入稟向恆天然集團索取1.2萬至3.3萬元賠償。

恆天然認為申索無法律根據，表示申索人的律師早前已在內地跟進賠償問題，這批家長亦在內地賠償方案之內，有關申索應在內地而非在香港進行。審裁官昨日並未裁決，要求原訴人提供資料，證明他們受害者的身分和服食了有關產品後的醫療報告，以證明三鹿集團延遲六個星期公布問題奶粉，導致身體受傷害，以及解釋為何三鹿的股東要為消費者服食產品出事而負責。此案尚待審裁官判決，家長若申索成功，意義重大。

突顯香港法治優勢

一國兩制生命力事例

首先是三鹿毒奶粉其他受害者，都可以援引來港申索，恆天然集團已把對三鹿集團的2億紐元（約11.2億港元）投資全數撇帳，若要為受害者負責，損失就更大了。另外，受害者家長在內地維權處處碰壁，遭到打壓；如果香港的法制可以給他們得到公道，對於內地人士而言，不啻在中國領土範圍內，找到一條可循法律手段維權的途徑。

現在內地許多國企和民企來港上市集資，他們在本港都有港人代表和業務，三鹿受害者家長在港若勝訴，這些國企和民企的業務若在內地出事（例如煤礦事故等），理論上，遇事者或其家屬就可以來港循民事程序，向出事國企或民企在港的公司索償。事態會否如此演變，正是此案重要和值得關注之處。

內地人士設法維權，官方致力維穩，維權不敵維穩，主要是執法不公，法律為政治服務；香港實行「一國兩制」，獨立公正的法律和司法體制是香港的優勢，也是香港維持繁榮穩定之所賴。三鹿毒奶粉案受害者家長不辭跋涉來港申索，突顯了香港法治制度的吸引力，如果內地人士維權創下成功先例，則香港的法制、法治輻射內地，這大概超逾了當年鄧小平構思「一國兩制」時的想像，可以理解為「一國兩制」具有生命力的事例。

After I watched this movie,I think the company are so selfish,it is because the company only thinking of how much they can earn,they do not thinking of the quality of the food and waht will happen if the people eat the food which have problem.

Beside that,it is horrible for me to know that the factories which produce food are so dirty when they are making the food.Also,the factories also change the DNA of the food,and it is not good for human body,but the speaker of the company said that it is not problem,are people problem,because if people do not buy the produce from us,they will not get sick.I think it is not a responsible answer.

Lastly,I think the government should do something to control the qulity of the food.I will choose the food produce carefully in the future.
