Question

Do you like seahorses? What do you know about them?
The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎動物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?

試題分析：文章主要講述了有關海馬這種海洋生物的一些知識。海馬其實不是馬，它比馬小的多。雄性海馬負責生育寶寶，海馬以浮游生物為生，它們能變換身體顏色來逃過天敵。
小題1:根據第四段“Seahorses situate themselves near deep, fast-running channels rich in plankton”可知，海馬生活在富含浮游生物的較深的、快速流動的水域，故選C。
小題2:根據第三段“Seahorses are an unusual kind of animal because the males (雄性) give birth to babies.”可知，第三段講的是，雄性海馬負責生育寶寶，故選C。
小題3:根據第四段“Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.”可知，海馬通過快速變換身體顏色來躲避天敵，故選B。
小題4:根據“...to keep themselves from being swept away”可知，grasp在此意為“抓住”，hold與其同義，故選B。
