—What were you doing when she dropped in?

    —I for a while and_________ some reading.

A. was playing; was going to do   B. played; did

C. had played; was going to do    D. had played; did

C


解析:

本題的時(shí)態(tài)考查具有一定的迷惑性。“she dropped in”發(fā)生于“play'’與“do some reading'’之間，故play用過去完成時(shí)，而do some reading用過去將來(lái)時(shí)。

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.

1. Most historians hold that the Chinese invented fireworks in the 9th century when they

discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.

2. In May of 1886, a law led John Pemberton, a pharmacist（藥劑師）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.

3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波爐). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.   

1.The right time order of the three inventions, according to the passage, should be_________.

A. fireworks, the microwave and Coca-Cola

B. fireworks ,Coca-Cola and the microwave

C. Coca-Cola , fireworks and the microwave

D. the microwave, Coca-Cola and fireworks

2.Percy Spencer found the microwave efficient in cooking when he was _______.

A. looking for a way to melt his chocolate

B. trying to know how a magnetron could cook

C. working to know how the magnetron works

D. asked to invent a restaurant microwave oven

3.What can we learn from the above invention stories? 

A. Experiments make great inventors of our time.     

B. Nothing is impossible if one tries each day.

C. Inventors come out of hard work at any time.

D. A small incident may lead to a great invention.

4.What’s the best title for the passage?

A. What great inventions they are!               B. Inventions from Three Countries.

C. Stories of Accidental Inventions.          D. The Human Inventions of time.
