They have arrived at lunchtime but their flight was delayed.

A.will B.can C.must D.should

 

D

【解析】句意為“他們本該午飯時到達，但他們的航班推遲了。”will have done將來可以完成；can have done可能做過……嗎？表示對過去行為的懷疑，用于疑問句；must have done一定做過某事，表示對過去事情的肯定推測；should have done本來應該做某事，而實際沒做。but their flight was delayed這樣的結果，說明他們本來該到達卻沒有到達，因此選D。

The cash machine is 47 years old, but where was the birthplace of this world-beating invention? New York? Tokyo? No. The first ever cash machine was born in Enfield Town, north London. It was a Scottish inventor, John shepherd Barron, who realized the concept of a self-service machine that could be used 24 hours a day, seven days a week, to withdraw cash from one’s own bank account. It struck the inventor while he was in the bath. He hit upon the idea of a chocolate bar dispenser, replacing chocolate with cash.

On September 2 in 1969, America’s first automatic teller machine (ATM) appeared in public, giving out cash to customers at Chemical Bank, New York. It was only able to give out cash, but in 1971, an ATM that could handle many functions, including depositing(存款) money, was introduced. Today there are over one million ATMs around the world, with a new one added every five minutes. It is reported that Americans over the age of 18 use their ATM card six to eight times a mouth. Not surprisingly, ATMs get their busiest workouts on Fridays. In the 1990s, banks began charging fees to use ATMs, a profitable move for them and an annoying one for consumers.

Consumers were also faced with an increase in ATM crimes. Robbers preyed(搶奪) on people using money machines in poorly lit or otherwise unsafe locations, and criminals also thought up ways to steal customers’ PINs (personal identification numbers), even setting up fake money machines to capture the information. In response, city and state governments passed laws such as New York’s ATM Safety Act in 1996, which required banks to install such things as surveillance cameras (監(jiān)控攝像頭), reflective mirrors and locked entryways for their ATMs.

1. What does the underlined word, “It”, in the first paragraph, probably refer to?

A. The opening time of the bank.

B. The concept of an ATM.

C. Ordinary banking service.

D. The act of withdrawing cash.

2. Which of the following is true about ATM?

A. It appeared earlier than the chocolate bar dispenser.

B. It was invented by a Scottish man in 1971.

C. It was at first free of charge for its consumers.

D. It was originally designed to deposit money.

3. What can we learn from the text? "

A.Americans under the age of 18 are not allowed to have an ATM card.

B.People are more likely to turn to ATMs for banking service on Fridays.

C.Criminals usually choose unsafe locations to steal customers' PINs.

D.The ATM crime rate in New York is much lower than that in other state

4. Which of the following might be the best title for the text?

A.How to Operate on an ATM

B.What is Waiting for ATMs in the Future?

C.The First ATM Opened for Business

D. The Unknown Truth about ATM
