For US $60, a recently-founded company called telling you about the brain behind the bark. Dognition's test measures a dog's intellect in several aspects-from empathy to memory to reasoning skills/ But don't expect it to measure your pet's IQ.) Dr. Hare, one of the venture's co- founders, says a dog's intelligence can't be described with a single number. Just as humans have a wide range of intelligences, so do dogs. The question is what type your dog relies on more. After you plunk your money down, Dognition's website will take you through a questionnaire about your dog: For example, how excited does your dog get around other dogs, or children? Do fireworks scare your pup? Then, Dognition guides you through tests that are as fun as playing fetch or hide-and-seek. At the end, you get a report of your dog's cognitive profile. Your dog could fall into one of nine categories: Ace, Stargazer, Maverick, Charmer, Socialite, Protodog, Einstein, Expert, or Renaissance Dog. That can give you something to brag about on Dognition's Facebook page. It also can shed new light on why dogs do the things they do. For example, a Charmer is a dog that trusts you so much that it would prefer to solve problems using information you give it rather than information it can get with its own eyes. Dognition helps people understand their dogs in ways that they have never been able to do. This new understanding can enrich the relationship between dogs and their owners.

英文問題 may not be什麼意思 感覺題目詳解給錯了

第 48 至 51 題為題組 Many of us have probably experienced déjà vu at least a few times in our life. Its meaning comes from the phrase "already seen" in French, and occurs when we feel that a person, place, or thing is familiar to us without actually having experienced them before. This strange phenomenon happens to as much as 70 percent of the population, but a higher number of 15 to 25 year olds experience it than any other age group. Maybe you just travelled to a new foreign country, and it just felt very familiar to you. Yes, you are feeling déjà vu; however, you know you haven't been there before. While different people experience déjà vu in different ways, it is still a pretty mysterious phenomenon, and researchers are putting the pieces together. Based on some studies, déjà vu is just a part of having a healthy memory checking system, and people who experience déjà vu more often are less likely to forget the details of important events. In fact, the results of the study don't look too promising in terms of mental health for people who never experience déjà vu. Scientists believe déjà vu is created by a neurological anomaly related to an improper electrical discharge in the brain. In short, it's not a mystical prophecy or out-of-body experience, but just your brain playing a trick on you; that is, these scientists dismiss it as just a glitch in the matrix. A few people are just terrified when it happens, but others feel euphoric about it. On average, most people just find it to be a perplexing sensation, neither pleasant nor threatening. Since déjà vu occurs in individuals with and without a medical condition, there is much speculation as to how and why it happens. Several psychoanalysts attribute deja vu to simple fantasy or wish fulfillment, while some psychiatrists ascribe it to a mismatching in the brain that causes it to mistake the present for the past. Many parapsychologists believe it is related to a past-life experience. Obviously, there is more investigation and researches to be done. So, does this article seem very familiar to you? 48. Which of the following CAN'T be described as a déjà vu experience based on this passage? (A) You keep buying similar style of clothing and you don't know why. (B) You feel you've been to a place when actually it's your first time there. (C) Someone looks familiar to you though you have never seen him before. (D) You just met a new friend whom you think you must have met somewhere. 49. Based on the article, which description about déjà vu is WRONG? (A) It actually is not as harmful to our mental health as we think. (B) Some people who have experienced it may feel a sense of happiness. (C) The word"déjà vu" originates from France, meaning"already seen." (D) Those who never experience it may not be mentally healthier than those who do.

Global Issues The White Helmets of Syria That has been described as the greatest humanitarian crisis What of the 21st century began in early 2011 with the outbreak of civil war in Syria. For years, this conflict has raged, claiming the lives of hundreds of thousands of people. In addition to the horrible death toll, millions of Syria's citizens have been left homeless or displaced. In fact, the conflict has led to the biggest refugee crisis since the Second World War. Warta simmi Like i Leves cooki 539 dedorq yiripid ei 31 opp JELENT 64 1. D B alos ni bib yo HET PROB Although it may seem that all hope is lost in that tiny part of the world, there is one organization that has been fighting for years to save lives. While it is officially called the Syria Civil Defence or SCD, its members are better known simply as the white helmets. They are volunteers who rush to bombing sites to rescue survivors and give people hope. They often show little regard for their own personal safety, and a great many have been killed or injured attempting to save the lives of others. The white helmets organization was established in rebel-controlled areas that were under constant air attack by government forces. The strategy of the government had been to target not only rebel fighters who opposed them but also the civilians living in the area. Rockets and bombs often destroyed entire neighborhoods, leaving countless innocent people dead and dying. To make matters worse, the government offered no official support since it was the one causing the destruction. Things changed in 2014, however, when the SCD was established. Its white-helmeted members began working tirelessly to pull people from the rubble and give them urgent medical care. It is estimated that they have saved close to 150,000 lives since then. In 2016, the SCD was recognized for its humanitarian efforts when it was nominated for the Nobel Peace Prize. 2.
