In a classic research-based TEDx Talk, Dr. Lara Boyd describes how neuroplasticity gives you the power to shape the brain you want. Recorded at TEDxVancouver at Rogers Arena on November 14, 2015. YouTube Tags: brain science, brain, stroke, neuroplasticity, science, motor learning, identity, TED, TEDxVancouver, TEDxVancouver 2015, Vancouver, TEDx, Rogers Arena, Vancouver speakers, Vancouver conference, ideas worth spreading, great idea, Our knowledge of the brain is evolving at a breathtaking pace, and Dr. Lara Boyd is positioned at the cutting edge of these discoveries. In 2006, she was recruited by the University of British Columbia to become the Canada Research Chair in Neurobiology and Motor Learning. Since that time she has established the Brain Behaviour Lab, recruited and trained over 40 graduate students, published more than 80 papers and been awarded over $5 million in funding. Dr. Boyd’s efforts are leading to the development of novel, and more effective, therapeutics for individuals with brain damage, but they are also shedding light on broader applications. By learning new concepts, taking advantage of opportunities, and participating in new activities, you are physically changing who you are, and opening up a world of endless possibility. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at http://ted.com/tedx
The difference between Present Perfect tense (We have gone) and Simple past tense (we went) – English Grammar Lesson Take the quiz : http://www.learnex.in/present-perfect-tense-we-have-gone-vs-simple-past-tense-we-went/ In this lesson, you will learn the difference between the present perfect and simple past tense. Often, people get confused when to use the above sentence structures. The Present Perfect tense: is used to speak about an action is completed in the present time period. This structure is always linked to the present time period and cannot be used to speak about an action that was completed in the past. It is also used to speak about an action that has no specified time. The verb is in the past participle form. Example 01: I have watched three movies this week. (‘this week’ is the present week. Use the present perfect tense with terms like ‘today’ ‘this morning’ ‘this year/month’) Example 02: I have completed my graduation. (time not specified) Example 03: My uncle has gone to New York three times. (We use the present perfect because he exists in the present and so far he has gone to New York thrice) Example 04: I have lived in London for seven years. (I still live in London in the present, till date) Negative Sentences: Use ‘not’ in the negative. Example 01: I have not seen John today Example 02: I have never eaten Chinese food. (till date I haven’t eaten Chinese) Questions: Place ‘have/has’ before the subject: Example 01: Have you ever watched a horror film? Example 02: Have you read ‘the secret’? The Simple past tense: is used to talk about a action that was completed in the past. The verb is in the past form. Example 01: I watched three films last week. (last week is a past time frame and so we use the past form ‘watched’) Example 02: I lived in London for seven years. (we use the past ‘lived’ as I no longer live in London in the present) Example 03: I completed my graduation in 2013. Example 04: My uncle went to NY three times. (here we use ‘went’ because he no longer exists in the current) Negative sentences: Make negatives using ‘did not/didn't’ followed by a verb in the present form. Example 01: I didn't see John yesterday. ( not ‘didn't saw’) Example 02: I did not have pizza last night. Questions: Use did before the subject to make a question. Example 01: Did you read the news paper yesterday? Example 02: Did you call me last evening?
Verbs come in three tenses: past, present, and future. The past is used to describe things that have already happened (e.g., earlier in the day, yesterday, last week, three years ago). The present tense is used to describe things that are happening right now, or things that are continuous. In grammar, tense is a category that expresses time reference with reference to the moment of speaking. Tenses are usually manifested by the use of specific forms of verbs, particularly in their conjugation patterns. Basic tenses found in many languages include the past, present, and future. Some languages have only two distinct tenses, such as past and nonpast, or future and nonfuture. There are also tenseless languages, like Chinese, though it can possess a future and nonfuture system, which is typical of Sino-Tibetan languages. On the other hand, some languages make finer tense distinctions, such as remote vs. recent past, or near vs. remote future. Tenses generally express time relative to the moment of speaking. In some contexts, however, their meaning may be relativized to a point in the past or future which is established in the discourse (the moment being spoken about). This is called relative (as opposed to absolute) tense. Some languages have different verb forms or constructions which manifest relative tense, such as pluperfect ("past-in-the-past") and "future-in-the-past". Expressions of tense are often closely connected with expressions of the category of aspect; sometimes what are traditionally called tenses (in languages such as Latin) may in modern analysis be regarded as combinations of tense with aspect. Verbs are also often conjugated for mood, and since in many cases the three categories are not manifested separately, some languages may be described in terms of a combined tense–aspect–mood (TAM) system. how to identify tense of a sentence? | tense table | tense rules | tense chart | tense in hindi (1) https://youtu.be/urWjo44syQ0 study king
