From his wearing, we can see he must be from a wealthy family. He also looks very gentle, so he can't be difficult to get along with. Now, he is talking with a student. According to his English accent, I know he may be from US. Last term, there were two exchange students from America in my class. However, I didn't see their names on the class list. I guess that they must have gone back to their country. If this exchange student could be in my class, I will have more chances to practice my spoken English with him. 我的发现 ①情态动词can, may, must, might, could等后接_________可以表示对现在或将来情况的推测； ②这些情态动词后接_____________则可以表示对过去情况的推测。 动词原形 现在完成时态 精研语法　巧点拨 返回 1．can与could的用法 (1)表示能力(could是过去式)。 My grandmother can do some shopping on the Internet，but she couldn't last year. 我奶奶会网购了，但是去年她还不会。 (2)表示猜测，意为“可能”，一般用于疑问句和否定句(could是过去式)。 Can this news be true? 这则消息是真的吗？ (3)表示请求和许可(could表示更委婉的语气，回答时只能用can)。 —Can/Could I go now? —Yes，you can. ——我现在可以走了吗？ ——是的，可以。 (4)用于肯定的陈述句中，表示理论上或习惯上的可能性。 As we all know，anyone can make mistakes. 我们都知道，任何人都可能犯错。 (5)习惯用法“cannot...too...”表示“无论怎样……都不过分，越……越好”。有时cannot可用can never替代。 We cannot thank you too much for what you've done for us.对于你们为我们所做的一切，我们怎么感激你们都不为过。 巧学活用1——单句语法填空 ①I _____speak Arabic fluently when I was a child and lived in Morocco.

But it says those contributions have been little recognized or valued． The international organization says 37 percentage of women do not use the Internet. It also says 259 million fewer women than men have access to the Internet. Yet, women make up very close to half the world's population. The UN says women are largely underrepresented in science, technology, engineering and mathematic careers. “Bringing women into technology results in more creative solutions and has greater potential for innovations that meet women's needs and promote gender equality，” says the UN's website. 　　For this year's International Women's Day, Secretary-General Antonio Guterres said in a statement, “Let us work together to build a more inclusive, just, and prosperous world for women, girls, men, and boys everywhere.” The IWD has its roots in the social and labor movement in the United States. It began in New York City on March 8, 1857, when female workers marched in protest (抗议) of unfair working conditions and unequal rights in clothing factories. The workers called for a shorter workday and better pay, the National Archives says. On March of 1908, women workers again marched through New York City to protest child labor and poor working conditions, and demand women's right to vote. 　　The first recorded celebration internationally was on March 19，1911, in Austria, Denmark, Germany and Switzerland． At that time, over a million people came out to support women's rights. After World War Ⅱ， several countries started to celebrate women's day on March 8.Two years later, the UN officially announced that date as International Women's Day in 1977.Some countries, including China, Russia and Uganda, also recognize it as a public holiday. Past UN celebrations have included the issues of climate change, rural women and HIV/AIDS. 语篇解读　本文为一篇新闻报道，今年妇女节的主题是数字化：创新和技术促进性别平等，文章还介绍了国际妇女节的由来。 1．Why does the UN focus on DigitALL in celebration of this year's IWD? A．People have attached less value to women's contributions. B．People tend to ignore women's role in international issues. C．Women account for a larger population of the world． D．Women have easier access to the Internet than men. 细节理解题。根据文章第二段“The UN says that from... engineering and mathematic careers.”可知，联合国在庆祝今年的国际妇女节时将重点放在数字化上是因为人们不太重视女性在信息技术上的贡献。故选A项。 √ 2．What is the advantage of bringing women into technology? A．Finding creative solutions to gender equality. B．Developing innovation potential to satisfy women. C．Encouraging more women to take up technology. D．Supporting women's rights through innovative approaches. 细节理解题。根据文章第二段“‘Bringing women into technology... gender equality，’ says the UN's website.”可知，让女性进入科技行业能开发创新潜力，使妇女满意。故选B项。 √ 3．Why does the author mention Antonio Guterres in Paragraph 3? A．To comment on women's positions in innovations. B．To state the purpose of celebrating IWD this year. C．To call for joint action in respecting women's rights. D．To illustrate the origin of International Women's Day. 推理判断题。根据文章第三段“For this year's International Women's Day... and boys everywhere.”可推知，作者在第三段提及Antonio Guterres是为了呼吁共同行动，尊重妇女权利。故选C项。 √ 4．What mainly makes IWD an official international day? A．The focus on the issues of world concerns. B．The worldwide efforts to build a better world． C．The official announcement of the day by the UN. D．The celebration of women's achievements in computing. 细节理解题。根据文章最后一段“Two years later, the UN officially announced that date as International Women's Day in 1977.”可知，国际妇女节成为一个正式的国际日主要是由于联合国对这一天的官方宣布。故选C项。 √ Ⅱ．语法填空(每小题1.5分，共15分) (全国Ⅱ卷) Decorating with Plants, Fruits and Flowers for Chinese New Year 　　Chinese New Year is a 1. 　　　 (celebrate) marking the end of the winter season and the beginning of spring.
