一、標(biāo)點符號

1.含義：

句中的標(biāo)點符號使用要規(guī)范。

2.類型：

（1）破折號和冒號符號

3. 用法

破折號

（1）表示停頓并強調(diào)破折號后面內(nèi)容，但不能分隔句子。

例句1: The students seem happy enough with the new plan, but the alumni — there was the problem.

解析：本句是有but引導(dǎo)的轉(zhuǎn)折句，alumni后的破折號只表示停頓。

（2）雙進雙出：強調(diào)插入成分，往往與前面的名詞內(nèi)容重復(fù)

例句2: It will prevent corporations — large and small — from buying influence with campaign contributions.

解析：本句的large and small由雙破折號連接，表示大小公司，與前面corporation內(nèi)容重復(fù)。

冒號

（1）連接兩個獨立句。

①獨立句：簡單句或主從句，不能只是從句。

例如1: Tom is a student: he studies SAT.

解析：本句中冒號分隔兩個簡單句，第二個句子解釋說明SAT。

例如2: Tom is a student who studies SAT: it is one of the standard tests.

解析：本句中由冒號分隔主從句和簡單句，第二個句子解釋說明SAT。

（2）后加短語，表示解釋說明，冒號之前必須是句子。

例如3: Tom who studies SAT: one of the standard tests in the world. ?

解析：本句冒號前只有Tom和who從句，主句沒有謂語動詞，所以錯誤，改為例句4.

例如4: Tom is a student who studies SAT: one of the standard tests in the world.

C. unlawful detention 

D. ,unlawful, detention

A. NO CHANGE

B. ,a talented artist 

C. -a talented artist- 

D. a talented artist: 

解析：通過破折號看出是標(biāo)點符號的考點，根據(jù)“主謂之間不能用標(biāo)點隔開”的原則，排除A/B/D項；又根據(jù)“雙進雙出”的原則，本句中a talented artist是Peter Watson的插入語并修飾PW這個人，所以選C。

題目檢測4

After lost the quarter game of FIFA World Cup 2022, all players of Netherlands felt sad about their journeys on this game: a single game which is watched by over 3 billion people in the whole world.

B. ; a single game which is watched by over 3 billion people in the whole world 

C. , a single game which is watched by over 3 billion people in the whole world

D. . A single game which is watched by over 3 billion people in the whole world

解析：通過冒號看出是標(biāo)點符號的考點，根據(jù)“句號和分號都可以分隔兩個獨立句”的原則，a single game后面只有which從句，而沒有主句，所以不是獨立句，所以排除B和D項；又根據(jù)“逗號不能分隔獨立句”的原則，排除C項；再根據(jù)“后加短語，表示解釋說明，冒號之前必須是句子”的原則，a single game+which從句解釋說明前面的game，而game前面是獨立句，所以選A。
