—Since 1995. 自从1995年就在里
(2)—How long have you lived in Wuhan?
你在武汉住了多长时间了?

2.“have been at/in+地点名词”表示“已在某地”。例如:

①We have learned English since two years ago.
我们从两年前就学英语。
②I've live here since 1990.自从1900年我就住在这里。
2)since还可作介词,后接表示起点时间的状语从句,从句谓语动词用一般过去时,主句谓语动词用现在完成时。例如:
①How long have you stayed here since you came to China?
自从你来中国以前,你呆了多久了?
注意
1)在“It is+一段时间+since从句”中,主句谓语动词be习惯用一般现在时代替现在完成时。如:
①It is just a week since we arrived in Beijing.
我们到北京刚好有一星期。
2)“since+时间点”和“for+时间段”都表示时间段,应和延续性动词连用,不和非延续性动词连用。例如:

5 None of us has.我们没有人去过。
1)none是代词。意思是“没打任何东西”,“没有任何人”,“一个人也没有(= no one)”。例如:
①I know none of them.他们我一个也不认识。
2)none可在句子中作主语或宾语。当none代替可数名词作主语时,
谓语动词可用单数形式,也可用复数形式;但代替不可数名词时,谓语动词只能用单数形式。例如:
①None of the films are/is interesting.没有一部电影有趣。
②There is none of it left.那东西一点也没剩下。
3)nobody, no one 和none的区别
▲nobody和no one都指代人,意思是“没有人”。作主语时谓语动词用单数形式,后面不能跟of短语,常常回答who和不确定的问题。例如:
①Luckily, nobody/no one was hurt in this car accident.
幸运的是,没有人在这场汽车事故中受伤。
②Who went to the school library this week? Nobody/no one.
这周谁去过学校图书馆?没有人。
▲none既可以指代人,也可以指借事物,意思是“没有人,没有东西”等,对三者(以上)人(物)否定,其反义词为all.后面可以跟of短语。作主语时,如果它指代的是可数名词,谓语动词用单数、复数形式都可以,常常回答 how many和how much以及有特定范围的问题。例如:
①How many of the women are teachers? None ( of them is/are).
这些女士中有多少是老师?一个也没有。
②How much water is left in the bottle? None (of it is left).
瓶里还剩多少水?一点儿也没剩。
注意
none和all是一对反义词,all表示三者或三者以上的人或事物的全部肯定,all not与none却不同义,因为none表示三者或三者以上人或事物的全部否定,译为“一个人也没有”或“没有任何东西”,而all not表示三者或三者以上人或事物的部分否定,译为“并不是(所有的)”,或“不都是(所有的全……)”例如:
①None of them are students. 他们都不是学生。
②All of them aren't students. 他们不都是学生。
6 Surfing is one of the world's most popular water sports.
冲浪运动是一项世界上最受欢迎的水上运动。
1)“one of+复数名词”意为“……中之一”,作主语时,谓语动词须用单数形式。如:
①One of the boys is a foreigner.这些男孩中有一个是外国人。
②I can only answer one of the three questions.
2)one of后常跟形容词的最高级形式。例如:
①The Changjiang River is one of the longest rivers in the world.
②Miss Yang is one of the most popular teachers in the school.
注意:此短语中的of表示部分关系,即of之前的数词为部分,of之后的名词为整体。
7 Now it is enjoyed by people all over the world.
现在它(冲浪运动)被全世界的人们所喜爱。
1.这是一个被动语态。被动语太的构成是:“助动词be+有物动词的过去分词”。主语it是动作的承受者,by后面的短语是动作的发出者,by在这里意为“被,由”。例如:
①English is spoken by many people. 英语被许多人说。
2. all over the world 意为”全世界”,相当于the whole world, around
the world 或 throughout the world. 例如:
①We have friends all over the world. 我们的朋友遍天下。
②Travellers and business people use English all over the world.
全世界的旅行者和商人都用英语。
8 Hawaii is famous for its beautiful beaches.

9 Every year, water sports, especially swimming and surfing.
attract large numbers of tourists to the islands. 每年水上运动,尤其是游泳和冲浪都吸引着大量的游客到这些岛上。
1. 1) large numbers of是a large number of的复数形式,意为“很多数量的”,“许许多多的”。是形容词词组,后接复数名词。当“a (large) number of+复数名词”结构作句子的主语时,谓语动词一般用复数,有时也可用单数。例如:
①A number of boys are/is in the classroom.许多男孩在教室。
2)用a number of表示数量很少时,就说a small number of,不说a little number of.
3) a number of与the number of 的区别
①A number of foreign scientists have come to visit Wuhan Universi-ty. 许多外国科学家来参观武汉大学。
▲the number of意思为“……的总数”,number指“数目”或“人数”,是句中真正的主语,由介词of引出的短语是修饰主语的定语,故动词须用单数形式。如:
①The number of the students in our class is forty-five.
我们班的学生数是45。
2 especially作副词,其同义词为particularly, specially,是“尤其”的意思,后面所接的人或事物,是对前面提到的人或事物的解释或强调,具体化到某个个体上。如:

neither... nor...“既不……也不……”为并列连词,可连接并列的主语、谓语、宾语和表语等。
1)作主语时,谓语动词要遵循就近原则,即谓语动词的形式由离它最近的词决定。如:
①It's neither pleasant to eat nor good for you.
这既不好吃,也对你没好处。
②Neither you nor I am a student.我和你都不是学生。
