湘教七年级重难点解析
Unit 5 Topic 1 重难点解析 河南 刘 健 1.【原文再现】—How do you usually come to school? 你通常怎样上学？
—I always come to school by bus. 我总是乘公共汽车上学。
【精彩解析】（1）“by+交通工具或交通方式”意思是“乘坐……”。如：by bike, by plane, by bus, by train, by ship, by subway, by car, by air (乘飞机，由空运), by water (乘船，由水路) 等。注意介词by和表示交通工具的名词之间不用冠词。另外，当表示“乘飞机，乘火车，乘地铁，乘公共汽车，乘出租车”等时，也可以用动词“take”，但要加冠词。若表示“骑自行车”时，要用动词“ride”，而不用“take”。如：
He goes to work by subway every day. =He takes the subway to work every day. 他每天乘地铁去上班。
I often go to school by bike.=I often ride a bike to school. 我经常骑自行车去上学。
（2）本话题中分别出现了“never, seldom, sometimes, often, usually, always”等副词，这六个副词我们称为“频度副词”。在句子中它们通常位于系动词、助动词或情态动词之后，实义动词之前。sometimes可以位于句首、句中或句末。often也可以位于句末。根据他们修饰动词时，动作所发生的频度不同，我们用以下方式对它们进行说明。
动作发生的可能性由大到小依次为：
always→usually→often→sometimes→seldom→never
如：
He never tells lies. 他从来不撒谎。
She seldom goes out in the evening. 她晚上很少外出。
Kangkang often goes to school by bike, but sometimes he goes to school by bus. 康康经常骑自行车上学，但有时他乘公共汽车上学。
The sun always rises in the east. 太阳永远从东方升起。
【现场操练】用never, seldom, sometimes, often, usually或always填空。
(1) He _____ helps the blind (盲人) cross the street.
(2) My brother is _____ asking me for money. I don’t like him.
(3) _____ she goes to school by bus. At other times she goes by bike.

(5) I like watching TV very much. But these days I _____ watch TV, because I’m very busy.
(6) I can’t swim at all. So I _____ go swimming in the river.
2.【原文再现】Very few students ride bikes. 很少有学生骑自行车。
【精彩解析】few, a few 和 little, a little都表示“有”的意思，但用法有别。few和little的意思是否定的，表示“很少”或“几乎没有”，可以与very连用，不能与only连用。而a few和a little的意思是肯定的，表示“一些，有一点”，可以与only连用。few和a few修饰可数名词，little和a little修饰不可数名词。如：
Few men can do it. 没有几个人能做这件事。
The old man has only a little money. 这位老人只有一点点钱。
I have a few friends. 我有几个朋友。
There is little water in the bottle. 瓶子里几乎没有水。

3.【原文再现】—And how often do they have ball games? 他们多久举行一次球赛？
—They have ball games four times a year. 他们每年举行四次球赛。
【精彩解析】how often是疑问副词，用于提问频率。回答how often引导的问句时，常用never, often, seldom, every day等频度副词回答，也可用表示单位时间内次数的词或短语来回答，如once, twice, three times a week, four times a year等。如：
—How often do you go to visit your grandparents? 你多久去看望一次你的祖父母？
—Twice a year. 一年两次。
