1. Italy is not as big as Russia. To compare the size of Italy and Russia, we can use the structure "not as + adjective + as." In this case, we are comparing the size, so we use the adjective "big" to describe both Italy and Russia. However, we determine that Italy is not as big as Russia. 2. Hamsters are not as dangerous as snakes. Here, we are comparing the danger level of hamsters and snakes. We use the adjective "dangerous" to describe both hamsters and snakes. However, we determine that hamsters are not as dangerous as snakes. 3. The River Thames is not as long as the Amazon. In this comparison, we are looking at the length of the River Thames and the Amazon. We use the adjective "long" to describe both rivers. However, we determine that the River Thames is not as long as the Amazon. 4. A kilo of gold is heavier than a kilo of rice. This comparison focuses on the weight of a kilo of gold and a kilo of rice. We use the adjective "heavy" to describe both objects. However, we determine that a kilo of gold is heavier than a kilo of rice. This might seem strange since they both weigh the same, but it's important to remember that gold is denser and more compact, which makes it feel heavier. 5. Chocolate is not as expensive as caviar. Here, we compare the price of chocolate and caviar. We use the adjective "expensive" to describe both items. However, we determine that chocolate is not as expensive as caviar. Caviar is generally considered a luxury food, and its price is higher compared to chocolate.
