     MSG (monosodium glutamate) is a food additive (食品添加剂), which has been widely used by many
food factories all over the world since it appeared first in Japan in 1909.
     MSG is a substance that is added to some food to improve its original (原先的) taste and colour. It is
used in foods around the world such as cakes, bread, frozen meats, fish and vegetables. In the beginning,
people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed
to have bad reactions (反应) to MSG after having had a meal at a restaurant. They included headaches and
quick heartbeat (心跳). It was also reported that MSG excited a person's brain and caused his death in Japan.
Scientists think that MSG may lead to many neurological disorders (神经紊乱). In mice studies done by a
university, the evidence showed the mice didn't want to eat the food including MSG.
     Today many food companies"hide" MSG on food labels (标签) by using different names. If you see
"natural flavorings", "hydrolyzed protein" and "spices" in a food label, you are probably seeing a hidden way
to "report" MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very
delicious to taste, but sometimes it is dangerous for our health because some poisonous food additives have
been added to the food.
     To protect people's health, our governments, from central to local, are taking actions to stop factories
producing poisonous food additives.

1. Monosodium Glutamate is _______.

A. a food
B. an additive
C. a factory
D. a country

2. MSG is often used in _______.

A. frozen meats
B. cups
C. clothes
D. book covers

3. The examples in the second paragraph tell us ________.

A. the food including MSG is delicious
B. people like to eat in a restaurant
C. mice like eating the food including MSG
D. MSG is not safe sometimes

4. If you see "natural flavorings", "hydrolyzed protein" and "spices" in a food label, you will know—________.

A. you must eat the food in a hidden way
B. the food label must be hidden
C. MSG is probably added to the food
D. you must report the food to your parents

5. The underlined word "substance" in the article means __________.

     Many students of English think that learning a new language is very difficult. Now think how difficult it
is to learn English when your brain is only the size of a bird's brain! That is what some birds can do.
     Many different kinds of birds can copy the sounds of language. African grey parrots are the best known
for this.
     Every December in London, the National Cage and Aviary Bird Show tries to find the best "talking" bird
in the world. One bird named Prudle stood out among the "talking birds". She won this prize for 12 years
from 1965 to 1976.
    Prudle was taken from her nest in Uganda in 1958. She was sold to Iris Frost in Seaford, England. Prudle
knew almost 800 words in English.
     Prudle was also the oldest bird in the world that lived in a cage. Ms. Frost took care of the bird until
Prudle died in 1994. Prudle was 35 years old.
     A different kind of bird, not a parrot, named Puck was tested in 1993. It turned out that Puck knew more
English words than Prudle knew. Puck knew more than 1,700 words.
   If a bird can do it, anybody can do it.

[ ]

A. African grey parrots.

3. How many years did Prudle win the speaking competition for birds?

[ ]

C. 55 years.
D. 8 years.

4. Puck was better than Prudle because ______.

     Ms Liu taught physics in a middle school. Last month she explained to one of her classes about
sound, and she decided to test them. She said to them, "Now, I have a brother in London. If I was
calling him on the phone, and at the same time you were 75 feet way, listening to me from across the
street, which of you would hear what I said first, my brother or you? Why?"
     The cleverest student answered at once, "Your brother, Ms Liu, because electricity (电) travels
faster than sound waves (波)."
     "That's very good," Ms Liu answered. But then one of the girls, Gao Hui, raised her hand and said,
     "I don't think so." "Your brother would hear you earlier because when it's eleven o'clock here, it's
only eight o'clock in London."

A. reason
B. sound
C. waves
D. electricity
