二.易错点记忆
一.固定短语since then
教材原文 Since then,people have been able to speak to each other over long distances.自那以来,人们可以进行远距离通话了。
since then意为“自那以来”,通常与现在完成时连用。
since在此处作介词,意为“从……以后,自……以来”,其后接过去的一个时间点作时间状语,如:since five years ago、since 1998等,用于现在完成时的句子中,可替换成“for+时间段”,此时句中谓语动词用延续性动词。
—It’s said that Singapore has a Night Safari for people to visit.
—So it is! I there twice since 2015.
A.have been B.have gone C.went
解析:句意:——据说新加坡有一个夜间野生动物园供人们参观。——的确是!自2015年以来,我去过那里两次了。根据“since 2015”可知此处用现在完成时,have been (to)表示“去过某地(已回)”,have gone(to)表示去了某地(未回),根据句意可知“我”去过那里两次,故选A。
二.allow的用法
教材原文 They allow people to keep in touch with each other anytime, anywhere.它们让人们可以随时随地保持联系。
allow是及物动词,意为“允许,使有可能”。allow sb. to do sth.意为“允许某人做某事”。

归纳拓展

A.to play; at B.to play; on C.playing; in D.play; on
解析:考查非谓语动词及介词。句意:妈妈允许我在星期六晚上玩电脑游戏。allow sb. to do sth.意为“允许某人做某事”,第一个空用动词不定式作宾语补足语,排除选项C和D;“Saturday night”是具体某天的晚上,第二个空用介词on,排除选项A。故选B。
三.固定短语keep in touch with
教材原文 They allow people to keep in touch with each other anytime, anywhere.它们让人们可以随时随地保持联系。
keep in touch with sb.意为“与某人保持联系”,意思与stay in touch with sb.相同,强调的是一种状态,常与表示一段时间的状语连用。
I have kept in touch with him for three years.我已经和他保持联系三年了。
注意:若强调动作“与……取得联系”,则要用get in touch with...,它不能与表示一段时间的状语连用。
归纳拓展 lose touch(with sb.)与be out of touch(with sb.)都表示“(与某人)失去联系”,前者强调动作,后者强调状态。
根据汉语意思完成句子。

从选项中选出可以替代画线部分的最佳选项。

A.cut...off B.keep...away from C.turn...off
解析:考查短语辨析。cut...off意为“切断……”;turn...off意为“关掉……”;keep...away from意为“使……远离……”,与keep...off同义。故选B。

教材原文 Can you guess what it is?你能猜猜它是什么吗?

—That’s interesting. I guess you often fix things for others in your school.
A.what do my classmates call me
B.what my classmates call me
C.why do my classmates call me
D.why my classmates call me
解析:句意:——妈妈,你知道我同学叫我什么吗?工程师。——这很有意思。我猜你经常在学校帮别人修东西。宾语从句要用陈述句语序,排除A和C选项;由上下文语境可知“know”后应用连接词what,排除D选项。故选B。

八.maybe与may be
Maybe 是副词,意思是“也许,可能”,在句中作状语,相当于perhaps,常位于句首
Maybe she’ll come this afternoon.她可能今天下午来。
may be may是情态动词,be是动词原形,与表语一起可构成系表结构,在句中作谓语

It is used for helping us to work and study. People can use it to chat online, search for information, watch movies, shop online and so on. It has become one of the most necessary things in our life.
Everyone should take action to protect the Earth at once. Thank you for listening.
