话题: 含羞草 难度: ★★ 建议用时:7'
Can plants learn and remember? Monica from Australia thinks so.
Monica and her team members did some tests on mimosas (含羞草). The plants close their leaves quickly when people touch them. They put some mimosas in 56 pots. Every time they dropped the pots from 30 cm high, the plants closed their leaves. Monica and her team members did this for a whole day. To their surprise, at the end of the day, the plants no longer closed their leaves at all. It seemed that the plants had learned that this action wouldn't hurt them.
Another surprising finding was that the plants might remember things for a long time. Monica dropped the same pots of mimosas four weeks later. The plants still didn't close their leaves.
Monica wasn't sure how plants learn and remember. “The plants don't have brains. Maybe they learn and remember with the help of their cells (细胞),” she said.
(B)1. When mimosas are touched, ____.
A. they open their leaves
B. they close their leaves
C. their leaves drop
(C)2. What did Monica find four weeks later?
A. The plants grew more leaves.
B. The plants closed their leaves.
C. The plants didn't close their leaves when dropped from a height.
(A)3. The underlined word “brains” in Paragraph 4 means “____” in Chinese.
A. 大脑
B. 心脏
C. 血液
(C)4. What can we learn from the passage?
A. Plants have brains.
B. Mimosas aren't easy to keep.
C. Some plants can remember things.

答案： I.1.B 根据第二段中“The plants close their leaves quickly when people touch them.”可知，当含羞草被触碰时，它们会迅速合上叶子。故选B。
2.C 根据第三段中“Monica dropped the same pots of mimosas four weeks later. The plants still didn’t close their leaves.”可知，四周后，她发现植物被从一定高度丢下后仍然没有合上叶子。故选C。
3.A 根据画线词后句“Maybe they learn and remember with the help of their cells(或许它们在细胞的帮助下学习和记忆)”可知，此处指植物没有大脑，画线单词表示“大脑”。故选A。
4.C 根据第一段“Can plants learn and remember? Monica from Australia thinks so.”及全文可知，本文通过对含羞草的研究告诉我们有些植物能够学习和记忆。故选C。
