4、and other arthropods but the Whistling Spider feeds on frogs and small birds. The Golden Orb Spider also feeds on small birds. A spider periodically sheds(蜕皮;脱落) its skin so that it can grow.

They will probably not thank you for this praise until they are in their twenties, but dont let that stop you from praising them during their childhood and teen years. J

19、ust be careful how you praise them. A little praise may go a long way especially if it is the right kind of praise.

20、ids should be praised primarily for their efforts, rather than for their personal characteristics, because if they are praised for effort, then a poor performance is more likely to be seen as a glitch(小故障), rather than a valid reflection of who they are as individuals.

26、h has a great effect on the mind, catches the readers attention and triggers moments of self-examination. Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others. In the first part of the researc

27、h, the brain activity of 30 volunteers was monitored as they read passages from Shakespeares plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language. While reading the common texts, normal levels of electrical activi

28、ty were shown in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than t

29、he common ones.

As a result, this lightening up process of the mind lasted longer than th

30、at when volunteers read common texts, encouraging further reading.
