Whether in the workplace or on the football field, effective teamwork can produce amazing results. However, working successfully as a team is not as easy as it may seem. Effective teamwork certainly does not just happen automatically; it takes a great deal of hard work and compromise. There are a number of factors that must be in place to make a good team.

Effective leadership is one of the most important factors of good teamwork. The team’s leader should possess the skills to create and preserve a positive working environment and motivate and inspire the team members to take a positive approach to work and be highly committed. An effective team leader will promote a high level of spirit and make them feel supported and valued.

Communication is a vital factor of all interpersonal relationship and especially that of a team. Team members must be able to articulate their feelings, express plans and goals, share ideas and see each other’s opinions.

Conflicts will arise no matter how well a team functions together. The best way to deal with conflicts is to have some organized methods of handling conflicts. Team members should be able to voice their concerns without fear of offending others. Instead of avoiding conflict issues, a hands-on approach that settles them quickly is much better. It is often advised that the team leader sit with the conflicting parties and help work out their differences without taking sides and trying to remain objective if possible.

The team leader must set a good example to create good teamwork. In order to keep team members positive and committed and motivated, the team leader himself needs to show these qualities. The team turns to the leader for support and guidance. So any negative words or behaviors on the leader’s part can be disastrous.

Regardless of what type of work you are in, knowing how to effectively work on and with a team is going to be extremely important to your success and that of your team.

单项选择题

上海人爱吃大闸蟹,阳澄湖的大闸蟹更是名噪国内外。但吃完大闸蟹,看到满桌狼藉的蟹骸,你可曾想过它的用途,可曾想过变废为宝
其实,蟹壳中还有一种丰富的自然资源,即甲壳素。甲壳素又名蟹壳素、聚乙酰氨基葡萄糖等,是一种维持和保护甲壳动物和微生物躯体的线性氨基多糖,广泛存在于节足动物类的翅膀或外壳中。壳聚糖又称聚氨基葡萄糖、可溶性甲壳素,是由甲壳素经脱乙酰化反应转化变成的分子量为12万~59万的生物大分子。从勃拉康于1811年描述甲壳素至今,甲壳素和壳聚糖已有100多年的发展历史。
也许你没有发现,在我们的日常生活中时时可见壳聚糖的身影。壳聚糖具有很好的抗菌活性,将其添加到固液食品中,既会对汁液有一定的澄清作用,又可以起到防腐保鲜作用,又由于壳聚栅只能溶解在弱酸中,因此特别适合酸性或低酸性的食品保鲜,如常添加于腌制食品中或用于海产、水果和保鲜。
用壳聚糖做原材料,让其溶液在聚乙烯膜上蒸发,进而在一个钢膜中加压即可形成软性接触眼镜,即隐形眼镜。壳聚糖作为原材料制备的隐形眼镜,其优异的透氧性和促进伤口愈合的特性,为发炎或受伤的眼睛的辅助治疗提供了美好前景。
壳聚糖具有良好的生物相容性和生物降解性,降解产物一般对人体无毒副作用,在体内不积蓄。用甲壳素、壳聚糖等原料制成的人工皮肤吸水性、透气性、组织相容性良好。若与乙酸合用,还有镇痛、抗感染等功效。
用甲壳素制成的吸收型外科手术缝合线力学性能良好,组织反应好,柔软性好,易打结,具有创伤治愈效果,伤口修复快,创口平整漂亮。在手术伤口愈合过程中,甲壳素缝线在体内的抗张强度逐渐下降,并在溶菌酶作用下首先分解成低聚糖,然后经一系列的化学反应,一部分以二氧化碳的形式由呼吸道排出体外,另一部分则以糖蛋白的形式为人体吸收利用。
(选自奚同庚主编的《原来如此·无所不在的材料》,上海科学技术文献出版社,2005)(北京安通学校提供)

关于在手术伤口愈合过程中甲壳素缝线变化的描述,恰当的是:

A.抗张强度逐渐下降
B.溶菌作用下分解成低聚糖
C.化学反应后最终得到多样产物
D.所有的生成物质都将被排出体外
