There are ways of helping our minds retain (记住) information, however, and in this activity you will explore ways that we lose and keep memories.

Short-term or working memory, is a way of describing most people's abilities to store a small amount of information for a brief period of time in a readily accessible form. People don't have to stop and think to remember something in short-term memory.

Such techniques include visualizing (使形象化) the information in a surprising way and linking pieces of information together so that one reminds you of the other. In the case of visualizing information, this could be as simple as remembering you parked your car on the fifth floor in the D section by picturing five dogs sitting in your car! If you need to purchase cereal (谷物), milk, fruit, cheese and eggs, you could imagine the cereal in a bowl, with milk pouring over it and pieces of fruit on top. Then imagine cracking an egg over everything, and it's full of melted cheese! These may seem simple or even silly. In this activity you'll test the recall of a few friends or family members, and learn a few tricks for improving memory!

Their objective was clear: to reach the Normandy beaches along about 80 kilometres of French coastline. The fiercest fighting was at Omaha Beach. The enemy were hiding, ready to attack the Allied soldiers even before they reached land. Boats were hit and men drowned, those who did make it to the beach faced heavy machine gunfire. By mid-morning, hundreds lay dead in the water and amongst the tanks on the beach. But, despite the high cost in human life, the D-Day landings were success and were seen (wide) as the beginning of the end of the Second World War.
