She unwound the string onto her finger, 【3】 (realize) that it could be used as weaving thread. Thus an industry was born. She taught her people how to raise silkworms, and 【4】 (late) invented the loom(織布機(jī)). Silk production reached 【5】 high level during the Shang Dynasty (1600BC—1046BC).

For more than two thousand years, the Chinese kept the secret of silk to 【6】 (they). It was one of the most guarded 【7】 (secret) in history. Anyone found guilty of taking silkworm eggs, cocoons, or mulberry seeds was put to death. Silk clothes were worn by emperors and rich people and became a symbol 【8】 wealth. Common people were prohibited from wearing silk. With the creases of travels and trading, sericulture 【9】 (slow) reached the outside world from Asia to Europe. Now most of silk 【10】 (produce) in the south of the Yangtze River Delta, such as Suzhou, Hangzhou, Nanjing, and Shaoxing.

【1】has

【2】when

【3】realizing

【4】later

【5】a

【10】is produced

【解析】文章介紹了絲綢在中國(guó)的發(fā)明及絲綢技術(shù)向國(guó)外的傳播的過(guò)程。

【1】考查主謂一致。主語(yǔ)為“raising silkworms for silk production”，動(dòng)名詞作主語(yǔ)，謂語(yǔ)動(dòng)詞用第三人稱(chēng)單數(shù)形式，故該空填has。

【2】考查固定句式。be doing sth….when…意為“正在做某事這時(shí)突然……”，是固定句式。

【3】考查非謂語(yǔ)動(dòng)詞。主語(yǔ)she和realize之間是主動(dòng)關(guān)系，故用現(xiàn)在分詞作伴隨狀語(yǔ)。

【4】考查副詞。later是副詞，意為“后來(lái)，以后”，在句中作狀語(yǔ)。句意：她教給人們?nèi)绾勿B(yǎng)蠶，后來(lái)發(fā)明了織布機(jī)。

【5】考查冠詞。level是可數(shù)名詞，該處指“一個(gè)較高水平”，故該空填不定冠詞a。

【6】考查反身代詞。keep sth. to oneself意為“保密，不和他人分享”，故該空應(yīng)填they的反身代詞themselves。

【7】考查名詞。one of+復(fù)數(shù)名詞，意為“……之一”，故該空應(yīng)填復(fù)數(shù)名詞。

【8】考查介詞。a symbol of意為“……的象征”。

【9】考查副詞。句意：蠶絲業(yè)慢慢地從亞洲到達(dá)了歐洲。slowly是副詞，修飾動(dòng)詞reach。

【10】考查被動(dòng)語(yǔ)態(tài)，時(shí)態(tài)和主謂一致。句意：現(xiàn)在，大部分絲產(chǎn)自長(zhǎng)江三角洲南部。時(shí)間狀語(yǔ)為now，故該句應(yīng)用一般現(xiàn)在時(shí)態(tài)。主語(yǔ)most of silk和produce之間是被動(dòng)關(guān)系，故該空應(yīng)用被動(dòng)語(yǔ)態(tài)，且most of silk是不可數(shù)形式，根據(jù)主謂一致原則，該空填is produced。

【題目】If you look on the Internet, you will see that almost every day of the year celebrates some kind of food. These “holidays” have become very popular across the United States. They give people a chance to enjoy something they might not eat normally, like National Onion (洋蔥) Ring Day, for example. Food holidays also give restaurants and other businesses a chance to promote their products.

But where did these American “holidays” come from? Many are the invention of an Alabama man, John-Bryan Hopkins. He writes about food for his Foodimentary. com website. Hopkins told Time magazine that when he began his site in 2006, there were only 175 “holidays.” “I filled in the rest,” he said.

The National Day Calendar has a list of all the different food and non-food related “holidays.” In the past, the website used to let anyone create their own day—for a price. But now, the site only accepts requests from businesses and other organizations.

While some food “holidays” are indeed made-up, many have historical roots. For example, National Beer Day on April 7 marks the end of a U. S. ban on the production, transport, import and sale of alcoholic drinks. The ban lasted from 1920 until 1933.

The Salvation Army, a Christian group, launched U. S. National Doughnut Day on June 1, 1938. It was meant to honor women who served soldiers doughnuts during World War I.

But not everyone likes food holidays. Bethany Jean Clement is a food writer for the Seattle Times newspaper. She wrote, “I get that some people might be excited by, say, National Doughnut Day. But you really can have a doughnut any day you want!”

Tavi Juarez, also of Foodimentary. com, thinks national food holidays are here to stay. She told the Seattle Times, “In my modest opinion, I believe that food holidays will continue to grow in popularity online because there’s a lot of negativity (消極) out there. Why not choose to celebrate food instead?”

【1】Why does the website accept others’ own day?

A. To promote traditional food. B. To make money.

C. To create new holidays. D. To attract more viewers.

【2】What is National Beer Day related to?

A. Law. B. War.

C. Right. D. Custom.

【3】Who dislikes food holidays?

A. John-Bryan Hopkins. B. The Salvation Army.

C. Bethany Jean Clement. D. Tavi Juarez.

【4】Which of the following can be the best title for the text?

A. Good Chances to Enjoy Particular Foods.

B. Traditional American Foods on the Internet.

C. Tricks of Businesses: Promotion of Products.

D. National Food Days: An American Tradition.
