【解析】

1.B 根據(jù)文中提到Put a short (0. 5 meter) board on two books. The books should be under the center of the board.往兩本書上放一個(gè)0.5米的板，書至于板的中央，故選B項(xiàng)。

2.D 根據(jù)文中提到Ask your partner to stand on one end. With your hands ， push down on the other end. Can you lift your partner，要求你的同伴站在板的一端，用你的手能翹你的同伴嗎？，故選D項(xiàng)。

3.C 根據(jù)文中提到Put a longer (1 meter) board on the books. The end should be about 30cm from the books. Have your partner stand on the end that's near the books. Can you lift your partner，放一個(gè)1米長的板在書上，末端離書30厘米，同伴離書較近，你能翹起他嗎，故選C項(xiàng)。

4.A 根據(jù)文中提到Now do the same with the longest (2 meters) board. The end should be half a meter from the books. What will happen? Yes ！ You can lift your partner easily，一個(gè)兩米長的板，站在離書半米的地方，看你能不能翹起他呢。故選A項(xiàng)。

5.B 題目中問這個(gè)什么樣的實(shí)驗(yàn)，這是個(gè)物理實(shí)驗(yàn)，故選B項(xiàng)。
