重點講解
1. full
full用作形容詞,有多種含義:
①「忙的」,其同義詞為busy。
②「滿的」,其反義詞為empty (空的),常用於be full of
(充滿……的)短語中。
③「吃飽了的」,其反義詞為hungry。
【運用】寫出劃線部分的漢語意思
(1) Sorry, the hotel is full this evening. _________
(2) I'm full, so I don't want to eat anything. _________
(3) Her life is full and she doesn't have time to relax. _________
2. maybe
用作副詞,意為「大概;或許;可能」,可與may be相互轉換。如:Maybe you are right. = You may be right.
【連結】may be是由情態動詞may加系動詞be構成的,意為「也許是;可能是」。它位於句中,與後面的表語一起構成謂語部分。
【運用】
Ⅰ. 選詞填空
1. ___________(Maybe / May be) you should often visit him.
2. Sara ___________(maybe / may be) in the museum now.
Ⅱ. 寫出同義句
1. She may be a singer.
___________________________________________
2. Maybe this is a boy's bedroom.
___________________________________________
3. more than
①後接數詞,表示「超過……;多於……」,同義詞為over,反義詞為less than(不到;少於)。
②後接名詞,表示「不只是;不僅僅」。
【運用】漢譯英
(1) 蘇州有著2500多年的歷史。
____________________________ (2017 江蘇蘇州)
(2) 我叔叔不只是一位老師。
____________________________
4. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week.
What percent of the students do not exercise at all?
①percent用作名詞,意為「百分之……」。英語中百分數的表達形式為「基數詞 percent」,percent無複數形式。
②當「百分數 of the 名詞」作主語時,謂語動詞的單複數形式由of後面的名詞的數來決定,即:of後面是複數可數名詞時,謂語動詞用複數形式;of後面是不可數名詞或單數可數名詞時,謂語動詞用單數形式。
③再次使用「百分數 of the 名詞」結構時,如果該名詞在前面已經提到,則可省略「of the 名詞」部分。
④對percent前面的基數詞提問時用疑問詞what。
【運用】選詞填空
(1) 60 percent of the water in the river ___________(is / are) dirty.
(2) About 80 percent of the young people ___________(likes / like) popular music.
(3) ___________(What / How much) percent of the students always drink juice?
5. It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise.
①It is 形容詞 (for sb.) to do sth.是英語中的常用句型,意為「(對某人來說)做某事……」。
②It is good to relax ... 中的to relax在句中作真正的主語(it是形式主語),而 ... the best way to relax ... 中的to relax在句中作定語。
③by和through用作介詞時,都有「憑藉;靠」的含義,後面接名詞、代詞或動詞-ing形式。
【連結】through用作介詞時還可意為「穿過」,強調從某一空間內穿過。
【運用】
Ⅰ. 選詞填空
by, through
1. The river runs ___________ the village.
2. The man became rich (富有的) ___________ his hard work.
3. John keeps healthy ___________ playing sports every day.
Ⅱ. 完成句子
