2、e of Education),which turned out to be a failure.My dad was reading my report card and saw that my position in class was 29th,but the number in class was 29.It meant that I had achieved the distinction of being bottom of my class.I wasnt lazy,and I was really trying.You can picture how I felt.Dad pu
3、t his hand on my shoulder and said,“You can only do the best you can,but whatever you decide to do,make sure you love it.”He was a really sweet guy and a great man.I knew his attempt to hide his disappointment with some of his encouraging words.I was depressed for a week,but his advice was a wake-up
4、 call.Fortunately I love working with my hands,and I was good at two things:woodwork and art,and I really loved to draw and paint.I was quite talented.Dad strongly encouraged me to go to art school,which in those days wasnt the obvious place that a father would suggest.So I got into Hartlepool Colle
5、ge of Art.The college was a revelation(出乎意料),the passionate teachers there,who were extremely interested in the students,not just tolerating them but actually engaging with them.It was a world apart from my schooling until then.Its extraordinary what an enthusiastic teacher can do,drawing the studen
6、t out,lighting independence,and encouraging a design of your own future,rather than waiting for something to happen.Im honored to have become one of these passionate teachers years later.My teachers inspired me,and thanks to my dad,here I am tonight.I think I should mention all the talents I have wo
7、rked with over time,and to my kids and my wife Giannina,thank you.Thank you for this great award.I shall find a very special place for it.1.How did the author feel after taking GCE?A.Happy.B.Upset.C.Tired.D.Relieved.2.What didHartlepoolCollege of Art impress the author most?A.The teachers were stric
8、t with students.B.The students set good examples for each other.C.The teachers inspired students passion for learning.D.The students got prepared for their lessons independently.3.The author gave this speech to _.A.share his career choice B.explain his teaching methods C.describe his life experience
9、 D.show his appreciation B With their tiny brains and excellent ability to memorize nectar locations,honeybees are a favorite model organism for studying learning and memory.Such research has indicated that to form long-term memoriesones that last a day or morethe insects need to repeat a training e
10、xperience at least three times.By contrast,short-and mid-term memories that last seconds to minutes and minutes to hours,respectively,need only a single learning experience.Exceptions to this rule have been observed,however.For example,in some studies,bees formed long-lasting memories after a single
11、 learning event.Such results are often regarded as circumstantial anomalies,says Martin Giurfa of the University of Toulouse.But the anomalous findings,together with research showing that fruit flies and ants can form long-term memories after single experiences,aroused Giurfas curiosity.Was it possi
12、ble that honeybees could reliably do the same?Giurfa reasoned that the ability to form long-term memories might depend on the particular type of bee and the experience.Within a honeybee colony,there are nurses,who clean the hive and feed the young;guards,who patrol and protect the hive;and foragers,
13、who search for nectar.While previous studies have tested bees as a whole,Ciurfa and his colleagues focused on foragers,tasking them with remembering an experience relevant to their role:an odor associated with a sugary reward.The researchers observed that a single exposure to a reward-paired odor wa
14、s enough for most forager bees to remember that specific odor the following day.Many foragers could even remember the odor three day later.The results do not mean that all prior research was wrong,says Andr Fiala of the University of Gttingen.“People have done the experiments in a different way.”Sti
15、ll,the new results do show that“the commonly held belief that one needs multiple training trials to achieve long-term memory is not always true,”he says,and this“really advances the field.”4.What does the author want to tell us through Paragraph 1?A.A model for memory research.B.The classification o
16、f memories.C.New research on learning and memory.D.Previous findings on memory formation.5.Which factor might influence a bees memory of an experience,according to Giurfas research?A.Whether the bees role is related.B.Whether the bee is introduced or native.C.How often the bee repeats the experience
17、.D.How long the bee is exposed to the reward.6.What is Andre Fialas attitude towards the new results?A.Doubtful.B.Favorable.C.Intolerant.D.Unclear.7.Which of the following is a suitable title for the text?A.Learning and Memory:How Honeybees Remember B.Honeybee Memory:Honeybee Knows What to Do C.Hone
18、ybees Remember after Just One Lesson D.Honeybees Use Memory for Communication C While the start of a new school year is always exciting,this year was even more so for some elementary school students inAuckland,New Zealand.They became the worlds first kids to be“taught”by a digital teacher.Before you

23、us far.Ravishankar says,“What was fascinating to me was the reaction of the children to Will.The way they look at the world is so creative and different,and Will really captured their attention.”However,regardless of how popular it becomes,Will is unlikely to replace human educators any time soon.8.
