2. 2 The anatomy Find the topic sentence in this paragraph. “…Of all the jungle people, the Pygmies are the most expert hunters and the finest trackers. The Belgian government does not allow them to carry modern firearms, so they must catch their meat and defend themselves with their own handmade weapons. But with these their marksmanship is truly marvelous. Often they shoot three or four arrows, one after another, so rapidly that the last may leave the bow before the first has reached its mark.” [From All About the Jungle.]

3. 3 Underline the topic sentence. Passage 1: “…The crocodiles of the Brazilian jungle are unpredictable creatures. As one suns himself on a sandpit, he looks like a log of weathered driftwood. But that log can come to life with amazing speed. Sometimes this huge reptile is cowardly and takes to the water at the sight of man. But a bull crocodile which is guarding a nestful of eggs left by his mate will savagely attack anything or anyone. Passage 2: “…Another unusual dweller of river and lake is the electric eel. In the whole animal kingdom, no more than half a dozen creatures can produce and electric charge, and these are all fish. Of these the electric eel discharges by far the strongest current-several hundred volts. Unlike other electric fish, the eel can control the discharge of electricity. It uses it’s current to kill or paralyze its prey. It locates the victim by sending out weak electric charges. These are reflected back to it much as radar picks up distant objects. Its dull greenish-gray body is four or five feet long.
