发现一个单词：jubilee，原来在天主教里面7年为一个安息年（shmita），7个7年以后便有一个禧年（jubilee），7*7+1=50，所以2000年会被称为千禧年，下一个禧年是2050年
The Jubilee year is the year at the end of seven cycles of shmita (Sabbatical years), and according to Biblical regulations had a special impact on the ownership and management of land in the Land of Israel; there is some debate whether it was the 49th year (the last year of seven sabbatical cycles, referred to as the Sabbath's Sabbath), or whether it was the following (50th) year. Jubilee deals largely with land, property, and property rights. According to Leviticus, slaves and prisoners would be freed, debts would be forgiven, and the mercies of God would be particularly manifest.
动词的进行时态（-ing）和过去时态（-id）都可以当形容词用，他们的差别是：
- 以后缀 –ed结尾的形容词（如ashamed, delighted, excited, frightened, interested, moved, pleased, surprised, worried等）通常用于说明人，不用于说明事物，即使它们所修饰的名词是事物，那它们指的也是与该事物相关的人。如：
He had a pleased smile on his face. 他脸上露出了满意的微笑。
He told me the news in a very excited voice. 他声音很激动地告诉了我这个消息。
第一句中的a pleased smile 意为“满意的微笑”，它指的是某人因感到满意发出的微笑；第二句中的 a very excited voice 指的是“很激动的声音”，即指的是某人因很激动而发生那样的声音。
原则上，-ed 形容词通常直接用于说明人，若修饰事物，则多为 air(神态), appearance(外貌), cry(哭声), face(表情), voice(声音), mood(情绪)等显示某人的情感状况的名词。
- 以后缀 -ing 结尾的形容词(如delighting, exciting, frightening, interesting, moving, surprising, worrying 等)主要用于说明事物，表示事物的性质或特征，若用它们说明人，则表示此人具有此性质或特征。
如：
The story is very interesting. 这个故事很有趣。
The man is very interesting. 这个人很有趣。
请再比较并体会以下句子：
He is frightened. 他很害怕。
He is frightening. 他很吓人。
He has a frightened look on his face. 他脸上带有惊恐的神情。
He has a frightening look on his face. 他脸上带有吓人的神情。
I read an interested expression on his face. 我看到他脸上露出一种感兴趣的表情。
I read an interesting expression on his face. 我看到他脸上露出一种有趣的表情。
最近接触心理学相关的单词比较多，梳理一下这几个意思比较接近的单词：
- Consciousness（意识，理性的思维层面本身上对事物的认知）
- Awareness（觉察，感性的感官层面上对事物的认识）
- Sensation（感受，反映的是由对象的各样基础属性）
- Perception（知觉，反映的是事物的意义，对感觉属性的概括，包含有思维的因素）
- Feeling（感觉，是对客观现实个别特性比如声音、颜色、气味等的反映）
- Insight（洞察，强调在没有提醒的情况下对一个问题的突然的灵感）
- Intuition（直觉，强调在没有充分的原因下做出的选择或者判断）
- Cognition（认知，获取知识的过程）
Consciousness is the state or quality of awareness, or, of being aware of an external object or something within oneself. It has been defined as: sentience, awareness, subjectivity, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind. Despite the difficulty in definition, many philosophers believe that there is a broadly shared underlying intuition about what consciousness is. As Max Velmans and Susan Schneider wrote in The Blackwell Companion to Consciousness: "Anything that we are aware of at a given moment forms part of our consciousness, making conscious experience at once the most familiar and most mysterious aspect of our lives."
Awareness is the ability to directly know and perceive, to feel, or to be conscious of events, objects, thoughts, emotions, or sensory patterns. In this level of consciousness, sense data can be confirmed by an observer without necessarily implying understanding. More broadly, it is the state or quality of being aware of something. In biological psychology, awareness is defined as a human's or an animal's perception and cognitive reaction to a condition or event.
Sensation，in psychology, sensation and perception are stages of processing of the senses in human and animal systems, such as vision, auditory, vestibular, and pain senses. Included in this topic is the study of illusions such as motion aftereffect, color constancy, auditory illusions, and depth perception. In other words, sensations are the first stages in the functioning of senses to represent stimuli from the environment, and perception is a higher brain function about interpreting events and objects in the world. Stimuli from the environment are transformed into neural signals, which are then interpreted by the brain, through a process called transduction. Transduction is the physical process of converting stimuli into biological signals that may further influence the internal state of the organism, including the possible production of conscious awareness or perception.
Perception is the organization, identification, and interpretation of sensory information in order to represent and understand the environment. All perception involves signals in the nervous system, which in turn result from physical or chemical stimulation of the sense organs. For example, vision involves light striking the retina of the eye, smell is mediated by odor molecules, and hearing involves pressure waves. Perception is not the passive receipt of these signals, but is shaped by learning, memory, expectation, and attention
Feeling is the nominalization of the verb to feel. The word was first used in the English language to describe the physical sensation of touch through either experience or perception. The word is also used to describe experiences other than the physical sensation of touch, such as "a feeling of warmth" and of sentience in general. In psychology, the word is usually reserved for the conscious subjective experience of emotion. Phenomenology and heterophenomenology are philosophical approaches that provide some basis for knowledge of feelings. Many schools of psychotherapy depend on the therapist achieving some kind of understanding of the client's feelings, for which methodologies exist.
Insight is the understanding of a specific cause and effect in a specific context. An insight that manifests itself suddenly, such as understanding how to solve a difficult problem. In psychology, insight occurs when a solution to a problem presents itself quickly and without warning. It is the sudden discovery of the correct solution following incorrect attempts based on trial and error.
Intuition, a phenomenon of the mind, describes the ability to acquire knowledge without inference or the use of reason. Intuition is often interpreted with varied meaning from intuition being glimpses of greater knowledge to only a function of mind; however, processes by which and why they happen typically remain mostly unknown to the thinker, as opposed to the view of rational thinking.
Cognition is "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses." It encompasses processes such as knowledge, attention, memory and working memory, judgment and evaluation, reasoning and "computation", problem solving and decision making, comprehension and production of language, etc. Human cognition is conscious and unconscious, concrete or abstract, as well as intuitive (like knowledge of a language) and conceptual (like a model of a language). Cognitive processes use existing knowledge and generate new knowledge.
