chronic
1、 Lasting a long time or recurring frequently.
2、 Always present; constantly annoying or troubling; habitual.
🌱He had stopped to pick up ice-cream cones for the kids, hoping it would give him a temporary rest from their chronic bickering. 🌳Chronic coughing goes on and on; chronic lateness occurs day after day; chronic lameness never seems to get any better. Unfortunately, situations that we call chronic almost always seem to be unpleasant. We never hear about chronic peace, but we do hear about chronic warfare. And we never speak of chronic health, only of chronic illness. chronology 1、 A sequence of events in the order they occurred.
2、 A table, list, or account that presents events in order.
🌱The scandal had gotten so complex that the newspaper had to print a chronology showing the order of the numerous events involved. 🌳History is much more than a simple chronology of events, but keeping events in chronological order is the first essential step in thinking about it. When, for example, historians try to show how World War I prepared the way for World War II, tracking the chronology of the events in the years between the two wars can help in explaining a complicated historical era. anachronism 1、 The error of placing a person or thing in the wrong time period.
2、 A person or thing that is out of its own time.
🌱A Model T Ford putt-putting down the highway at 25 miles per hour was an anachronism by 1940. 🌳In Shakespeare's time, playwrights didn't worry much about anachronisms. When Shakespeare saw his plays performed, all the characters, even Romans and Greeks, would have been dressed in the clothes of his own period. Macbeth, which is set in the 11th century, contains anachronistic references to clocks and cannons, which the real Macbeth would have known nothing about. Today, a writer may spend months doing research in order to avoid anachronisms in the historical novel she's working on. Using the second meaning of the word, we could say that manual typewriters and slide rules are anachronisms in these days of computers and calculators, and a person who likes doing things the old-fashioned way might himself be described as an anachronism. synchronous 1、 Happening or existing at exactly the same time; simultaneous.
2、 Recurring or acting at exactly the same intervals.
🌱The theory depends on whether the chemical appeared in synchronous deposits worldwide seven million years ago. 🌳Communications satellites are usually put into a synchronous （or geosynchronous） orbit, circling the earth once every 24 hours and so appearing to hover over a single spot on the surface. This type of synchronized movement is important, since you have to know where to aim your satellite dish. In the computer field, synchronous usually refers to the use of a simple timing signal that permits very rapid exchange of data between computers. The kind of mysterious coincidence sometimes called synchronicity—such as the appearance of two different comic-strip characters named Dennis the Menace in the U.S. and Britain within three days of each other in 1951—has fascinated people for centuries.

CHRON comes from the Greek word for "time." A chronicle records the events of a particular time, which is why so many newspapers have the name Chronicle. A chronometer is a device for measuring time, usually one that's more accurate (and more expensive) than an ordinary watch or clock.🌸
