1.听写包 答案：

Well, in 1908, Kikunae Ikeda identified a fifth 'taste'.

And it is thought that MSG intensifies this naturally occurring 'taste' in some food.
It does make perfect evolutionary sense that we should have the ability to detect or taste glutamate because it is the amino acid which is most common in natural foods.
John Prescott, an associate professor at the University of Chicago, suggests that this fifth taste serves a purpose just as the other tastes do.
He suggests that it signals to us the presence of protein in food, in the same way that sweetness indicates that a food contains energy-giveing carbohydrates.
Bitterness, he says, alerts us to toxins in the food, while sourness warns us of spoilage and saltiness signals the presence of minerals.
So, what else do we know about this fifth taste...
在1908年，池田菊苗发现了第五种味道。
味精很自然地加强了一些事物的味道。
因为谷氨酸盐是在自然食物中很常见的氨基酸，所以我们能够发现并尝出它的味道，从进化的角度看，这是说得通的。
芝加哥大学副教授，约翰·普雷斯科特认为这第五种味道和其他的味道作用相同。
他认为这表示食物中蛋白质的存在，就像甜味表示食物中包含补充能量的碳水化合物。
他说，苦味提醒我们食物有毒，酸味警告我们食物变质，而咸味表示矿物质的存在。
那么，对于第五种味道，我们还知道什么……

3.写作包答案：

China's film market has been developing at a high speed, but China's animation industry is not to our satisfaction. Last year, 33 animation films were released, none of which did well at the box office. The reasons are as follows: firstly, the low investment. A Hollywood animation film spends more than half of its budget on screening and special effects, which, however, in China, usually accounts for only 10%. Secondly, the tedious plot. Currently, few animation films in China can achieve more than 0.1 billion yuan at the box office. According to the insiders, boring plot is the main reason for low box office. Besides, its hard to find a good scriptwriter with low payment.
