橈腳類有時會在供水系統中出現,,尤其是沒有過濾的供水。在已處理的供水系統中並不怎麼有問題,但在如秘魯孟加拉熱帶國家,就有發現橈腳類與在未經處理供水中的霍亂有關,而霍亂菌是附在浮游生物的表面。這可以透過過濾供水來減低問題的影響。

越南已經成功以橈腳類來控制帶病的,如傳播登革熱埃及斑蚊。將橈腳類(如中劍水蚤大劍溞屬)加入容器中,牠們可以在容器中生活多個月,攻擊、殺死及掠食孑孓。這類生物控制方法須與清理及回收垃圾等配合,以消除蚊子滋生的地方。

請依下文回答第 28 題至第 32 題 During the mid-1900s, scientists began to examine biological cycles in several different organisms. By the early 1960s, they showed that daily, or circadian, rhythms—“circameaning around and “dia” day—are generated internally and synchronized to the 24-hour day. How are these cycles generated and altered? In mammals, including humans, a biological clock resides in a region of the brain’s hypothalamus, a quarter-sized structure that regulates hormone levels and plays a role in emotions. In some insects and snails the clocks are usually located in the retina of the eye. In birds the clocks can also be found in a brain region called the pineal gland or in the hypothalamus. The clocks are almost always linked to some form of light-sensing cell called a photoreceptor. This type of cell responds to sunlight in ways that help synchronize the clock with the 24-hour day. Scientists have learned that exposure to light at certain times in the internal cycle can reset the clock in animals. In mammals, light turns on important genes and affects sleep patterns, alertness, and body temperature. In nature, this light sensitivity helps organisms synchronize their clock within the cycle of day and night. Researchers have found that exposure to strong artificial light at certain times can reset the clock in ways that relieve insomnia, jet lag, and mental disorders. Light at the wrong time of the internal cycle, however, might contribute to or intensify these conditions.
【題組】28 According to the passage, in which of the following organs can a mosquito’s biological clock be found?
(A) Brain
(B) Eye
(C) Nose
(D) Tongue

9. _______________ In this mosquito-infested country, an estimated 450,000 families live in high-risk malaria prevalent areas. Luckily, there is a simple and cost effective way to protect children from malaria. One insecticide treated bed net costs US$6 only and lasts up to five years. Sleeping under it can reduce overall child mortality by 20 percent. The public’s support for this United Nations International Children’s Emergency Fund (UNICEF) project can save a lot of children’s lives.
(A) The United Nations International Children’s Emergency Fund is working with the government of Myanmar to provide effective and affordable malaria prevention to families with small children.
(B) Malaria is both preventable and treatable, and effective preventive measures as well as curative tools have been developed by non-governmental organizations.
(C) To reduce vulnerability to malaria and to combat the spread of malaria, the United Nations International Children’s Emergency Fund distributed insecticide treated bed nets exclusively to Myanmar households.
(D) According to the United Nations International Children’s Emergency Fund, approximately half of malaria deaths in the Southeast Asia region occur in Myanmar’s malaria prevalent townships.
