It’s plain common sense—the more happiness you feel, the less unhappiness you experience. It’s plain common sense, but it’s not true. Recent research reveals that happiness and unhappiness are not really two sides of the same emotion. They are two distinct feelings that, coexisting, rise and fall independently.

People might think that the higher a person’s level of unhappiness, the lower their level of happiness and vice versa. But when researchers measure people’s average levels of happiness and unhappiness, they often find little relationship between the two

The recognition that feelings of happiness and unhappiness can co-exist much like love and hate in a close relationship may offer valuable clues on how to lead a happier life. It suggests, for example, that changing or avoiding things that make you miserable may well make you less miserable, but probably won’t make you any happier. That advice is backed up by an extraordinary series of studies which indicate that a genetic predisposition for unhappiness may run in certain families. On the other hand, researchers have found happiness doesn’t appear to be anyone’s heritage. The capacity for joy is a talent you develop largely for yourself.

Psychologists have settled on a working definition of the feeling—happiness is a sense of subjective well-being. They have also begun to find out who’s happy, who isn’t and why. To date, the research hasn’t found a simple formula for a happy life, but it has discovered some of the actions and attitudes that seem to bring people closer to that most desired of feelings.

Why is unhappiness less influenced by environment? When we are happy, we are more responsive to people and keep up connections better than when we are feeling sad. This doesn’t mean, however, that some people are born to be sad and that’s that. Genes may predispose one to unhappiness, but disposition can be influenced by personal choice. You can increase your happiness through your own actions.

[A] unhappiness is more inherited than affected by environment.

[A] As a result.

[B] In addition.

[C] At present.

[D] Until now.

4. What do you think the author believes about happiness and unhappiness?

[A] One feels unhappy owing to his miserable origin.

[B] They are independent but existing concurrently

[C] One feels happy by participating in more activities.

[D] They are actions and attitudes taken by human beings.

5. The sentence “That’s that” (Para. 5) probably means: Some people are born to be sad

治疗中最难恢复的是


A.血红蛋白
B.网织红细胞
C.白细胞
D.血小板
答案:D
解析:
[考点]再生障碍性贫血的诊断和治疗
[分析]该患者血红细胞、白细胞和血小板均减少,呈现全血细胞减少,白细胞分类计数示淋巴细胞比例增高,骨髓虽然增生活跃,但淋巴细胞、浆细胞和组织嗜碱细胞等非造血细胞比例增高,臣核细胞明显减少,所以最可能的诊断是再生障碍性贫血,其余三种疾病虽然也可有全血细胞减少,但骨髓检查结果均不支持;该例再生障碍性贫血属于慢性,首选治疗是雄性激素,可促进骨髓造血,而叶酸和维生素B12是用于治疗巨幼细胞贫血,MP方案化疗用于多发性骨髓瘤的治疗,碳酸氢钠用于阵发性睡眠性血红蛋白尿的治疗;治疗最难恢复的是血小板,其余还有可能恢复。

郭某曾立下书面遗嘱,将其全部遗产3间房屋和2万元存款给长子郭甲继承。但弥留之际,郭某看到郭甲似乎在窃笑,巴不得自己赶快死,便宣布把自己的全部遗产给次子郭乙继承。当时在场人员有护士小王、郭甲、郭乙及郭某的女儿郭丙。郭丙患有严重的精神病,无业在家。郭某对郭丙很讨厌,故未考虑过给她遗产。问:
(1)两个遗嘱以哪一份为准?为什么?
(2)已立为准的遗嘱效力如何?为什么?
(3)如果郭甲为争夺遗产,在郭乙水杯中下毒,但误把白糖当作砒霜,则发生什么民事后果?为什么?

答案:
解析:
(1)书面遗嘱有效,而口头遗嘱无效。因为口头遗嘱不符合两个或者两个以上见证人在场见证的条件,依据继承法,见证人不能是继承人或者与继承人有利害关系的人。 本案中,只有一人即护士小王符合见证人的条件,其他人则不能作为见证人。
(2)书面遗嘱没有给患有严重精神病的郭丙留有必要的遗产份额,由于郭丙属于缺乏劳动能力且没有生活来源的继承人,因此应当为其保留必要的遗产份额。所以该书面遗嘱只能是部分有效。
(3)郭甲的行为属于为争夺遗产而故意杀害其他继承人的情形,根据继承法,为争夺遗产故意杀害其他继承人的,丧失继承权。本案中,郭甲为了继承遗产而故意杀害郭乙,则丧失继承权。郭甲丧失继承权后,郭某的遗产不能按照遗嘱继承,此时应当依照法定继承办理,即由郭乙、郭丙继承郭某的遗产。
【精解】本案例适用的法条主要有:《继承法》第7条(继承权的丧失)、第17条(遗嘱的形式要件)、第18条(遗嘱见证人资格)、第19条(保留必留份原则)。这里有一个问题需要澄清,即保留必留份原则属于法律的强制性规定,立遗嘱人不得违反,即便遗嘱中没有给缺乏劳动能力又没有生活来源的人保留必要的遗产份额,在分割遗产时,这部分遗产也要强行分出。

下列关于糖皮质激素作用的叙述,哪一项是错误的( )

A.促进蛋白质分解、抑制其合成
B.对保持血管对儿茶酚胺的正常反应有重要作用
C.减弱机体对有害刺激的耐受
D.抑制胰岛素与其受体结合,导致葡萄糖利用减少
答案:C
解析:
肾上腺皮质分泌的糖皮质激素有多种生物学作用。例如:促进肝外组织,特别是肌肉组织蛋白质分解,由于分解增强,蛋白质合成减少;促进糖异生,升高血糖,而且还有抗胰岛素作用,以至外周组织对葡萄糖的利用减少;能增强血管平滑肌对儿茶酚胺的敏感性,有利于提高血管的张力和维持血压;在应激反应中ACTH和糖皮质激素有重要的作用,大大增加机体对有害刺激的抵抗力(C错误);此外糖皮质激素还对水盐代谢和血细胞有影响。
