It helps me to keep my concentration on the activity in hand, makes me focus more on my studies, and gives me some pretty brilliant ideas while talking to myself; more importantly, I produce better works. Do you talk to yourself? Dont get embarrassed at admitting it because science has discovered that those who talk to themselves are actually geniuses but not crazies!Psychologist Gary Lupyan conducted an experiment in a supermarket where 20 volunteers were shown objects, and were asked to remember them. Half of them were told to repeat the objects, for example, bananas, and the other half remained silent. In the end, the result showed that selfdirected speech aided people to find the objects faster, pared with the silent ones.“I often talk to myself when searching for something in the refrigerator or on the supermarket shelves，” said Gary Lupyan. This personal experience actually made him conduct this experiment. Lupyan, together with another psychologist, Daniel Swigley, came up with the oute that those who talk to themselves are geniuses. Here are the reasons：When you are talking to yourself, your sensory mechanism gets activated. It gets easier on your memory since you can visualise (使具體化) the word, and you can act accordingly.Every one of us tends to have various types of thoughts. Most make sense, while the others dont. Suppose you are furious at someone and you feel like killing that person. Now for this issue you wont run to a doctor, will you? No, what you do is lock yourself in a room and mutter to yourself. You are letting go off the anger by talking to yourself about the pros and cons of killing that person, and eventually you calm down. This is a silly thought that you have and are unable to share it with any other person. Psychologist Linda Sapadin said, “It helps you clarify your thoughts, tend to whats important and firm up any decision you are thinking about.” 寫作步驟第一步：歸納主旨大意主旨大意：本篇為說明文。文章的主題是“自言自語的人是天才”。短文結(jié)構(gòu)分析：全文分為三個部分。第一部分(第一段)：為導(dǎo)入段，引出自言自語不是問題，事實(shí)上自言自語的人是天才；第二部分(第二、三段)：實(shí)驗(yàn)研究的情況；第三部分(第四、五段)：說明了自言自語的優(yōu)點(diǎn)有助于刺激記憶力，使頭腦清晰。第二步：提煉關(guān)鍵詞Part 1：1.I talk_a_lot_to_myself. It helps me to keep_my_concentration_on_the_activity in hand.2Those who talk_to_themselves are actually geniuses but not crazies！Part 2：3.Psychologist Gary Lupyan conducted_an_experiment in a supermarket where 20 volunteers were shown objects, and were asked to remember them.4Lupyan, together with another psychologist, Daniel Swigley, came up with the oute that those who_talk_to_themselves_are_geniuses.Part 3：5.When you are talking to yourself, your sensory mechanism gets_activated. It gets easier on your memory since you can visualise the word.6It helps you clarify_your_thoughts.第三步：合并和改寫1要點(diǎn)1和2合并：Talking a lot to oneself helps one focus on the activity in hand and people who like to talk to themselves are supposed to be geniuses.改寫：Talking a lot to oneself helps one focus on what_he_is_doing and people who have_this_habit are actually geniuses.2要點(diǎn)3和4合并：Psychologist Gary Lupyan conducted an experiment about it and he, together with another psychologist, Daniel Swigley, concluded that those who talk to themselves are geniuses.改寫：Psychologist Gary Lupyan conducted an experiment about it and he and psychologist Daniel Swigley concluded its_true.3要點(diǎn)5和6合并：When you are talking to yourself, your memory can be stimulated and it helps you clarify your thoughts.改寫：Talking_to_yourself does good as follows: on the one hand, it stimulates your memory; on_the_other_hand,_it helps you clarify your thoughts.第四步：核查成文核查連貫性，優(yōu)先考慮使用最短連接詞；核查標(biāo)點(diǎn)和語法；核查詞數(shù)。最終成文如下：Talking_a_lot_to_oneself_helps_one_focus_on_what_he_is_doing_and_people_who_have_this_habit_are_actually_geniuses._(要點(diǎn)1)Psychologist_Gary_Lupyan_conducted_an_experiment about_it_and_he_and_psychologist_Daniel_Swigley_concluded_its_true._(要點(diǎn)2)The experiment_showed_that_talking_to_yourself_does_good_as_follows:_on_the_one_hand,_it_stimulates_your_memory;_on_the_other_hand,_it_helps_you_clarify_your_thoughts.(要點(diǎn)3)一、復(fù)現(xiàn)單元考點(diǎn)增強(qiáng)備考信心.高考中的語法填空1(2018全國卷)The team transforms the familys long weekend of celebration with less expensive but still tasty (taste) recipes.2(2018全國卷)Wang collected more than 7 million abandoned (abandon) bricks of different ages. 3(2017浙江高考)Italy, which has a much weaker tradition of immigration, has_witnessed (witness) a sharp increase in immigration in recent years.4(2016全國卷)Nurses and other caregivers need to be aware of the possible meanings of silence when they e across the personal anxiety their patients may be experiencing. 5(2015北京高考)These animals typically live between the surface of the ocean and a depth (deep) of about 3,300 feet as far as most light can reach.6(2010湖南高考)The cultural difference in eye movements that they show is probably a reflection (reflect) of cultural difference in facial expressions.高考中的完形填空(選用urge, witness, abandoned, aware of填空)1(2018北京高考完形填空)For many, finding an unattended wallet filled with 400 in cash would be a source (來源) of temptation (誘惑)But the _16_ would no doubt be greater if you were living on the streets with little food and money.
