Summer is here, bringing with it plenty of the insects we all love to hate: the mosquitoes. It may seem as if mosquitoes bite everyone and everything, but believe it or not, they are very picky eaters. They are only likely to bite someone that they think smells good, just as we are only likely to eat food that smells good.

　　Mosquitoes are attracted to the natural smells that our bodies give off. Carbon dioxide and lactic acid are two of the chemicals that mosquitoes are most attracted to. Both of them are released through our breath and skin. Mosquitoes are also attracted to the smells given off by the soaps, perfumes, shampoos, and body lotions that we use every day.

　　So the next time a mosquito bites you, remember, it is a compliment: The mosquito just likes the way you smell!




Guess Who's for Dinner/蚊子也挑食
　　夏天到了，随之而来的是大量的我们都很讨厌的昆虫──蚊子。也许看起来好像蚊子会叮任何人，任何东西，但信不信由你，它们是非常挑食的。蚊子只可能叮它们认为气味好闻的人，就像我们只喜欢吃香喷喷的食物一样。

　　蚊子会被我们身体散发出的自然气味所吸引。二氧化碳和乳酸是最吸引蚊子的两种化学物质。它们都是通过我们的呼吸和皮肤释放出来的。蚊子还会被我们每天使用的肥皂、香水、洗发香波、沐浴露发出的味道所吸引。

　　因此下次蚊子叮你时，要记住，这是一种恭维：蚊子只不过是喜欢你的气味啦。

　　英语小教室

　　夏季里蚊声鼎沸，虽然蚊子的嗡嗡声(the mosquito buzzing)很烦人，但这对蚊子来说很重要，因为那是一种求偶的呼唤(a sort of mating call)。其实，雄蚊子(the male mosquitoes)是不叮人的，只有雌蚊子(the female mosquitoes)叮人。雌蚊子在咬人时，会射出一种有毒液体进入人体的血液(injecting a poisonous liquidsintosthe blood)，引起痒、痛，甚至红肿(itching, pain, or swelling)。由于蚊子是疟疾(malaria)、登革热(Dengue fever)等危险疾病的传播者(carriers of dangerous diseases)，所以夏天到野外郊游一定要注意做好防蚊措施(taking precautions against mosquitoes)。
