2.細節(jié)理解題。根據(jù)文章第四段"Thedraftalsosaysthatanimalabuseandabandoninganimalswillbeconsideredcrimesunderthecriminallaw."可知B、C兩項不被接受,最后一段中"Itsaysthatpeopleshouldnotforceanimalstodosomethingdangerous,likejumpingthrougharingoffire."可知D項也不能被接受。

Chooseatimewhenyounormallyfeeltiredsothatyoucanfallasleepeasily.七選五答案：EGADF

解析：①根據(jù)上文中的"Whatworksforsomemightnotworkaswellforothers"可知,對一些人有效的方法不一定對其他人也同樣有效,所以應該找到最適合自己的睡眠習慣。故選E。②根據(jù)上文中的"Setaregularbedtime.Gotobedatthesametimeeverynight"可知,本段主要講要制訂一個有規(guī)律的睡眠時間。因此接下來應說選擇一個自己通常感到疲倦的時刻,這樣你能夠容易入睡。故選G。③根據(jù)下文中的"Ifyougetenoughsleep,youshouldwakeupontimenaturallywithoutanalarm"可知,如果你得到了足夠的睡眠,你應該不需要鬧鐘就可以按時自然醒來。故本段主旨句應該是說每天在相同的時間醒來。故選A。本段中的"keepyourregularwake-uptime"也是信息提示。④根據(jù)上文中的"Whiletakinganapcanbeagreatwaytorechargeone'sbatteries,especiallyfortheelderly,itcanmakeinsomnia(失眠)worse"可知,小睡雖然是一個養(yǎng)精蓄銳的好方式,尤其對老年人來說,但是它能使失眠更嚴重。接下來應該說,如果失眠對你來說是一個問題的話,那么應該考慮放棄小睡了。故選D。⑤根據(jù)上文中的"Whatshouldyoudowhenyouaregettingsleepybeforeyourbedtime?"可知,上句講到"在你睡覺之前,如果感到困倦的話,應該怎么做?"那么接下來應該說的是減少倦意的方式,故選F。三、完形填空
