（三）重點句型
［句型學習］
welcome to…
【用法】歡迎來到……（welcome在此處為感嘆詞）
welcome to ＋ 地點名詞，welcome ＋ 表示地點的副詞
如：welcome to my school! welcome home!
welcome還有以下用法：
（1）作動詞，意為“歡迎，迎接，樂意接受”。
如：they are welcoming the new students.
we welcome his idea.
（2）作形容詞，意為“受歡迎的，不必感謝的”。
如：—thank you very much. —you’re welcome.
（3）作名詞，意為“歡迎，迎接”。常用于“give sb. a warm welcome 熱烈歡迎某人”這一短語中。
如：the students give the new teacher a warm welcome.
＝the students give a warm welcome to the new teacher.
＝the students welcome the new teacher warmly.
【考查點】welcome的用法
【易錯點】welcome to…中的to何時省略不明確。
【考題鏈接】guangzhou is hosting the asian games. _________________ guangzhou.
a. welcome b. welcome to c. welcoming to
答案：b
解題思路：此題考查“welcome”的用法，由于guangzhou是地點名詞，welcome后要接to, 故選b。
（四）重點語法
［語法學習］
主謂一致
謂語動詞要在人稱和數上與主語保持一致，稱為主謂一致。
英語中的主謂一致可分為三個原則：1）語法一致的原則 2）意義一致的原則 3）鄰近一致的原則
1. 語法一致的原則
（1）以動詞不定式短語或動名詞短語作主語時，謂語動詞要用單數，例如：
to work hard is necessary for a student.
doing morning exercise is good for your health.
（2）由and或both…and連接的并列成分作主語時，謂語動詞要用復數。例如：
both he and i are right.
mr black and mrs black have a son called tom.
但并列主語如果指的是同一人，同一事物或同一概念，則謂語動詞要用單數。例如：
his teacher and friend is a beautiful girl.
the poet and writer has come.
（3）主語是單數時，盡管其后接有but, except, besides, with，along with, together with, as well as 等介詞短語
或連詞短語，謂語動詞仍用單數。例如：
the teacher with his students is going to visit the museum.
nobody but two boys was late for class.
mary together with her parents has gone to beijing.
he as well as i is responsible for it. 不只是我，他對這件事也負有責任。
（4）一些只有復數形式的名詞，如people, police, cattle, clothes等作主語時，謂語動詞要用復數。例如：
a lot of people are dancing outside.
the police are looking for lost boy.
（5）由each, some, any, no, every 構成的復合代詞作主語時，謂語動詞都用單數。例如：
is everybody ready?
somebody is using the phone.
（6）由兩部分構成的物體的名詞，如glasses, shoes, trousers, chopsticks, scissors 等作主語時，謂語動詞要用復數。例如：
—where are my shoes? —i can’t find them.
your trousers are dirty. you’d better change them.
