There are two kinds of memory: short-term and long-term. Information in long-term memory can be recalled at a later time when it is needeD.The information may be kept for days or weeks. In contrast, information in short-term memory is kept for only a few seconds, usually by repeating the information over and over.

The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate, advanced, and native-speaking students. To begin, the subjects listened to a recording of a native speaker reading a paragraph in English.
Following the recording, the subjects took a 15-question test to see which words they remembereD.Each question had four choices. The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alikE.For example, weather, whether, wither, and wetter are four words that sound a likE.Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test.
Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning.

Easter is probably the most important Christian holiday on the calendar because it commemorates Christ’s resurrection from the deaD.Like many other religious holidays, though, Easter has incorporated many traditions from pagan beliefs and pre-Christian rites of seasonal regeneration. The word Easter has Indo-European roots and means “dawn”. This is a direct reference to the pagan goddess of dawn and new lifE.
The egg, a symbol of Easter, is a sign of fertility which reflects ancient spring renewal rites and beliefs that have been absorbed into the Christian tradition. Even the Easter bunny who brings the eggs was the escort of the Germanic goddess Ostara, who had a holiday named after her that fell on the vernal equinox. This serves to underscore the pagan elements that still remain a part of this quintessential Christian holy day. In the United States, Easter is celebrated in several ways.
On Easter morning children usually begin their day by looking for Easter eggs that the Easter bunny has hidden for them. Of course, most children know that the eggs were hidden by their parents, not the Easter bunny. In fact, many children help their parents color the Easter eggs, knowing that soon they will be eating them as a snack on Easter day. Some cities have Easter egg hunts at the local parks. Since Easter is always celebrated on Sunday, many people attend “Sunrise services” at their local church.
In fact, more people go to church on Easter Sunday than at any other time of the year. Sunrise services begin very early in the morning, usually right about the same time as when the sun begins to rise, and last until almost noon. After church families gather and have a big holiday feast. Easter also marks the coming of spring. People are usually happy that winter is over, so parks are usually full of people who want to get outside and enjoy the fresh air.
Which of the following best defines Easter?
A.It is partially religious.
B.It is a Christian holiday.
C.It is purely a religious tradition.
D.It is the most important Christian holiday.
The Easter egg represents __________.A.spring
B.new life

D.Easter
What is the main point of the third paragraph?A.Children like eating eggs on Easter.
B.Children help their parents on Easter.
C.People participate in many activities on Easter.
D.A lot of people go to church on Easter.

B.hunting Easter eggs
C.buying gifts for children
D.having religious ceremonies
Why do people go to parks on Easter?A.Because spring is coming.
B.Because it is part of the celebration.
C.Because the air is fresh on that day.
D.Because they feel free on that day.
