WRITING SECTION

Integrated writing task

Topic discussed: sucralose对人体有害

Notes

Reading: 

支持观点

1.会影响immune system,对人有害。因为小白鼠吃了后,某些器官shrinking,这个器官在人体是掌管免疫能力的,小时候吃了会有long-term effect.

2. 蔗糖素用化学成分替换了正常糖中的原子,会形成一种有毒的化学物质,导致中毒。

3.蔗糖素其实还是含糖的,吃了也不能减肥。

Lecture: 反驳

反对观点

1. 蔗糖素很好,那个实验是因为给老鼠吃了很大量的蔗糖素所以才会中毒,人吃不了那么多,所以没事。

2. 替换的那个成分不会被人体吸收,而且在fat issue中含量不高,所以没有害。

3. 以前的那些糖成分会在加热的时候被破坏,但是蔗糖素不会。同时可以bake things,可以成为代替真糖的调味品。而且没有依赖性,所以还有减肥作用。

Glossary

immune 免疫力

sucralose 蔗糖素

 

背景知识

蔗糖素

蔗糖素生成过程中,一个糖分子中的三个H)和O)基团被三个氯(Cl)原子取代。这时,蔗糖素就不再属于糖类了,而成为了人造甜味剂,其甜度是糖的600倍。

蔗糖素不会被人体代谢,因此不含热量。该物质中含有的氯元素不仅可防止其为人体所吸收,同时还使其具备了足够的抗热性,因此可用于烘焙食物中(而其他甜味剂在烘焙的过程中就失去了甜味)。1998年,FDA批准将该物质用于食物和饮料。

 

蔗糖素属非营养型强力甜味剂,在人体内不参与代谢,不被人体吸收,热量值为零,可供肥胖心血管病糖尿病患者食用是。另外,三氯蔗糖不被龋齿病菌利用,不会引起龋齿,故可应用于各种保健糖果当中。是一种适合消费者健康要求的甜味剂。 人体不能识别三氯蔗糖作为能量物质的碳水化合物,而且在人体中不参与代谢从而三氯蔗糖没有热量。三氯蔗糖对于糖尿病人也是健康食品,因为它不会提高血糖浓度也不会提升血清胰岛素浓度。故适合于各种低卡路里或减肥食品。

 

三氯蔗糖已经在美国、加拿大、澳大利亚等 80 多个国家允许作为食品添加剂使用,我国卫生部在 1997 年批准使用。三氯蔗糖已广泛应用于饮料、口香糖、乳制品、蜜饯、糖浆、面包、糕点、冰淇淋、果酱、果冻、布丁、调味乳、酱及酱制品、醋、蚝油、酱油、芥末 酱早餐谷物、甜乳粉、糖果、发酵酒、果酱类、热加工过的水果或脱水水果、烘培食品、水果馅、固体饮料、浓缩果蔬汁、色拉酱等加工食品中,有餐桌上的甜 味剂之美誉;同时可用于保健食品和医药中。

 

Independent writing task

Essay question

do you agree or disagree with the following statement? The most important quality for a politician or leader to have is good communication skills.

【话题提示】

非原创

Sample answer

 Such is human nature to strive for the position of a leader, for a highly qualified leader could temper his or her comprehensive talents, earn the maximum admiration and respect after obtaining the objectives. People differ greatly in their views as to what makes qualified leaders. An opinion springs up that communication skill tops all. As I see it, a good speech-craft is crucial for a leader,however,it is never the only standard of eminent leaders.
 
Effective communication ability must fall into the qualities of eminent leaders. To be the leader is what many of us aspire after, although not everyone could fulfill this dream. The connotation of leadership might include many elements. First-class speech-craft and perfect communication skills is, by all means, the manifestation of mighty leadership both for politicians and leaders. First, as for politicians, effective communication skills help to quickly resolve unexpected crisis, strive for assistance both home and abroad, even win over the utmost support from the general public. To illustrate, almost every American president is articulate and eloquent.
 
Good speech-craft is one of the most significant qualities of outstanding leader, yet, not the best or sole one. Other qualities of good leaders are not far to seek. Future-mindedness, implementation capability and frustration toleration are indispensable to a prominent leader. First, true great-achievers are all far-sighted and could never fail to lead the team to the right direction, one decision-making ability decides whether team members' endeavors could have desirable return. Second, action speaks louder than words. Compared with communication skills, exceptional implementation competence could earn more respect from others and give an inspiration to the team. More precisely, a leader should work even harder if he wants to motivate his team members to work diligently. Last, it is no easy task to achieve success no matter in obtaining goals, developing careers and even constructing countries, the journey to success can be chronic and challenging, thereby, a good leader must defy hardship and danger, hack his way through difficulties and finally embark on the triumphant road.
 
Overall, it is my view that good speech-craft and effective communication skill are vital to a politician or leader, however, on no account can we ignore the immense value of future-mindedness, implementation capability and frustration toleration
