【解析】

條形碼是我們?nèi)粘I钪薪?jīng)常會用到的,它使我們的生活更加方便。你知道條形碼是誰發(fā)明的嗎?這篇短文給我們介紹了這段歷史。

1句意:對于條形碼這項發(fā)明你知道什么嗎?

invent發(fā)明,是一個動詞。空前有the,空后有of,這個空應(yīng)用名詞形式。invent的名詞是invention,意為“發(fā)明,發(fā)明物”,空后只提到了一種發(fā)明,應(yīng)用單數(shù)形式。故答案為invention。

2句意:一個小食品店的老板發(fā)現(xiàn)很難保存產(chǎn)品信息的記錄。

空后small food store owner“小食品店的老板”,是一個名詞單數(shù)形式,結(jié)合文意這里表示泛指“一個……”,因此這個空填不定冠詞。small是輔音音素開頭,應(yīng)用a修飾,位于句首,第一個字母大寫。故答案為A

3句意:1948年,他要求德雷塞爾研究所來解決這個問題。

solve解決,是一個動詞。根據(jù)句子結(jié)構(gòu)可知,該句中使用了句型ask sb. to do sth.“要求某人做某事”,這里應(yīng)用動詞不定式作賓語補足語。故答案為to solve。

4句意:伯納德·西爾弗是一名研究生,他對這項技術(shù)很感興趣。

interest興趣,使感興趣,可以作動詞或名詞。由空前的was是系動詞,這個空應(yīng)填形容詞形式。而且主語是人,表示“某人感興趣的”,應(yīng)用interested。interesting也是形容詞,它用來形容物,表示“令人感興趣的”。故答案為interested。

5句意:很快,他們發(fā)明了他們的第一個工作系統(tǒng)。

they他們,是人稱代詞主格形式。結(jié)合句意和空后的first working system是名詞可知,該空應(yīng)用形容詞性物主代詞,作定語,修飾名詞。故答案為their。

6句意:這個系統(tǒng)一開始確實有效,但它非常昂貴,有時系統(tǒng)也不太好用。

根據(jù)句意可知,這里考查的是固定短語at first,意為“開始,起初”。故答案為at。

7句意:最后,Woodland解決了它們。

final最后的,最終的,是一個形容詞。由句子結(jié)構(gòu)可知,該空修飾的是后面整句話的內(nèi)容,應(yīng)用副詞形式。位于句首,第一個字母大寫,故答案為Finally。

8句意:在1949SilverWoodland申請了條形碼系統(tǒng)的專利,但直到1952年才獲得該專利。

根據(jù)句意可知,這里表示“直到……時候,才……”,考查not…until…,所以這個空應(yīng)填的是until,意為“直到……時候”,可以作連詞或介詞。故答案為until。

9句意:雖然專利給了,但是這個系統(tǒng)仍然不受商店老板的歡迎。

give給,是一個動詞。根據(jù)句意可知,該句主語this patent與動詞give構(gòu)成被動關(guān)系,應(yīng)用被動語態(tài),空前有了was,該空應(yīng)填過去分詞形式。故答案為given

10句意:從那以后,它變得非常受歡迎,現(xiàn)在全世界所有的商店都在使用它。

type類型,種類,是一個名詞?涨坝all修飾,表示“所有的”,因此名詞應(yīng)變?yōu)閺蛿?shù)形式。故答案為types。

這是一篇說明文,短文介紹了條形碼的由來。文章主題明確,內(nèi)容貼近日常生活,比較容易理解。題型是語法填空,考查方式有兩種:一種是用空后所給單詞的正確形式填空,這種類型主要考查實詞的用法,如動詞、名詞、形容詞、副詞等;另一種是沒有給出提示詞,要求填寫適當?shù)膯卧~,這種類型主要考查虛詞的用法,如介詞、冠詞、連詞等。其中第一種考查方式所占的題目較多一些。學生應(yīng)熟悉各個詞類的相關(guān)語法,如名詞單復數(shù)、所有格;動詞的時態(tài)、被動語態(tài)、非謂語動詞;形容詞和副詞的比較級以及詞性轉(zhuǎn)化;介詞、冠詞的固定搭配等等。如第1小題、第4小題和第7小題,考查了詞性的轉(zhuǎn)化;再如第3小題和第9小題考查了動詞的用法。

Do pretty school uniforms lead to early romance?

A technical secondary school in Nanjing planned to order Korean-style school uniforms for students, but parents didn’t agree because they believed that the new uniforms looked too good and would encourage early romances among the students.

Parents

“My daughter was so excited about the Korean-style uniform, saying it’s her dream to wear mini-skirt to school every day,” a mom complained. “Girls also talk about how handsome the boys looked in the uniform! If the students wear such beautiful uniforms, how can they study well? I prefer the sports wear which makes me think of health and positive(積極的) thinking.”

Students

The students are sorry about the school’s final decision. They think the sports wear uniforms make them look androgynous (難分性別).

They said the Korean-style uniform has many advantages such as raising interest in class and lifting confidence. It is also considered to be a good way to develop their sense of pride for the school and help then create good temperaments(氣質(zhì)).

As for romance, the students believe that love is love and has nothing to do with the uniform.

School

“The plan to change the school uniform from sports wear has been cancelled,” Mr Lin, a teacher, told the interviewer.

“The students dislike the present uniform, most of the students prefer Korean style school uniforms. We know cities like Shanghai and Guangzhou have changed their sports wear school uniforms to more fashionable uniforms. However, we had to stop the plan because many parents are strongly against it. Some parents think it’s just a way for the school to make money, and others think the new uniforms will take students’ attention away from their studies,” Lin said.

When asked about the problems with early romance between students because of the more fashionable uniforms, Lin said he hadn’t considered it. He, however, agreed that the Korean-style uniform makes the students more attractive.

Education department

“We don’t have a unified (統(tǒng)一的) standard for school uniforms. The schools can choose their own styles. Either sports wear or uniforms are OK,” an official said.
