D. READING (2p)

Read the following passage and do the exercises below

When we are young, we learn that tigers and sharks are dangerous animals. We might be scared of them because they are big and powerful. As we get older, however, we learn that sometimes the most dangerous animals are also the smallest animals. In fact, the animal that kills the most people every year is one that you have probably killed yourself many times: the mosquito.

While it may seem that all mosquitoes are biters, this is not actually the case. Male mosquitoes eat plant nectar. On the other hand, female mosquitoes feed on animal blood. They need this blood to live and produce eggs. When a female mosquito bites a human being, it transmits a small amount of saliva into the blood. This saliva may or may not contain a deadly disease. The result of the bite can be as minor as an itchy bump or as serious as death.

Because a mosquito can bite many people in the course of its life, it can carry diseases from one person to another very easily. Two of the most deadly diseases carried by mosquitoes are malaria and yellow fever. More than 700 million people become sick from these diseases every year. At least 2 million of these people will die from these diseases.

Many scientists are working on safer and better ways to kill mosquitoes, but so far, there is no sure way to protect everyone in the world from their deadly bites. Mosquito nets can be placed over beds to protect people against being bitten. These nets help people stay safe at night, but they do not kill any mosquitoes. Mosquitoes have many natural enemies like bats, birds, dragonflies, and certain kinds of fish. Bringing more of these animals into places where mosquitoes live might help to cut down the amount of mosquitoes in that area. This is a natural solution, but it does not always work very well. Mosquitoes can also be killed with poisons or sprays. Even though these sprays kill mosquitoes, they may also harm other plants or animals.

Although mosquitoes may not seem as scary as larger, more powerful animals, they are far more dangerous to human beings. But things are changing. It is highly likely that one day scientists will find a way to keep everyone safe from mosquitoes and the diseases they carry.

Insects on the Menu

Humans have a long history of eating insects, and it turns out that they can be a very nutritious part of a person’s regular diet. Insects have a lot of protein, and they are often easier to catch than prey animals. Therefore, it is no wonder that when our ancient ancestors saw some tasty worms or grubs wiggling on the ground, they made a quick snack of them.

In Thailand, insects are a regular part of the street food that can be found. The different insects that people snack on are crickets, grasshoppers, giant water bugs, and assorted worms. They are often deep-fried and salted, so they have a crunchy texture that makes them a perfect snack food. If you can get past the fact that you are eating a cricket, it will crunch in your mouth just like a corn chip!

For a lot of people, however, it is difficult to get over the fear of eating insects. People tend to see insects as invaders, especially when they are crawling on the food that we are about to eat. Therefore, being able to eat insects without feeling disgusted is cultural. Some people cannot eat French cheese or stinky tofu because they weren’t brought up doing so. To many of us, insects fall right into that category, making it difficult to even try them.

If given the chance, though, be courageous. Insects can be nutritious and tasty, so long as you can get over the “yuck” factor.

Which is the reason given for gathering and eating insects?
