【題目】2019年4月18日13時1分在臺灣花蓮縣海域(北緯24.02度,東經(jīng)121.65度)發(fā)生6.7級地震,震源深度24千米。結(jié)合相關(guān)知識,完成下面小題。

1與該次地震有關(guān)的板塊是

A.亞歐板塊與非洲板塊B.美洲板塊與印度洋板塊

C.太平洋板塊與亞歐板塊D.南極洲板塊與印度洋板塊

2該地發(fā)生地震的原因是

A.板塊的張裂運(yùn)動B.板塊的擠壓碰撞C.火山爆發(fā)D.樓房倒塌

3地震發(fā)生時,下列做法正確的是

A.坐電梯迅速下樓B.高層跳窗逃生

C.遠(yuǎn)離房屋等建筑物D.帶好現(xiàn)金等財(cái)物再逃生

【答案】

1C

2B

3C

【解析】

板塊構(gòu)造學(xué)說認(rèn)為,地殼是由六大板塊構(gòu)成,分別為亞歐板塊、印度洋板塊、太平洋板塊、非洲板塊、美洲板塊、南極洲板塊,板塊之間會發(fā)生張裂和擠壓運(yùn)動,板塊交界處地殼極不穩(wěn)定,形成了兩大火山地震帶即:環(huán)太平洋火山地震帶和地中海喜—馬拉雅火山地震帶。

1我國是一個多火山,地震的國家,臺灣位于太平洋板塊和歐亞板塊的交界處,環(huán)太平洋火山地震帶上,地殼活躍,多火山和地震。故選C。

2太平洋板塊與亞歐板塊向相對的方向運(yùn)動,發(fā)生碰撞擠壓,交界處地殼極不穩(wěn)定,發(fā)生了此次地震。故選B

3地震發(fā)生時,不要驚慌,要就近躲在有承重墻的內(nèi)墻角處躲避,或盡快跑到戶外空曠處,遠(yuǎn)離房屋等建筑物,以免被砸傷,不能從窗戶跳下,逃生時不要乘坐電梯或走樓梯逃生,以免不必要的傷亡,地震時逃生時最重要的,不能顧及財(cái)物,所以ABD做法錯誤,C做法正確。故選C。

本題主要考查板塊運(yùn)動及影響和地震時的逃生方法,理解解答即可。

【題目】 Do you shop online with websites like Taobao? The money you pay doesn't go directly to the seller. Instead, it goes through Alipay, which keeps your money for a while. After you receive your goods and click the “confirm receipt” button, Alipay then gives the money to the seller.

The process is called “third party online payment”. There is a transfer station, or a third account, between sellers and buyers to make online shopping safe. Buyers don't need to worry about paying for goods and then receiving nothing. Sellers also get rid of the risk of receiving no money after sending out goods.

These transfer stations are usually set up by payment service companies such as Alipay, Tenpay and Yeepay. Among them, Alipay is the biggest in China. It has more than 270 million active users, according to Xinhua.

While most online sellers and shoppers like the third party online payment system, banks are not very happy. That_is_because_companies_like_Alipay_are_fighting_over_money_with_the_banks. Users can invest in financial products through Alipay and make money. Thus lots of people choose to put money in Alipay rather than in banks.

But WeChat payment is not the same. WeChat doesn't have its own account. When paying through WeChat, the buyers' money goes directly to the sellers. That's why so many people are excited about receiving and handing out “red envelopes” or gift money to their friends on WeChat.

Whether Alipay or WeChat payment, they are all trying to attract more users and make online shopping easier. These two companies are also promoting payments through fingerprints. New payment methods such as quick response codes have become popular too.
