【题目】A Diet Without Enough Protein Can Cause Depression

Depression is a condition so common. 1 The World Health Organization (WHO) calls it “a leading cause of disability.” Difficulty in falling asleep, loss of appetite, and loss of ability to concentrate are just a few of the other effects of depression. While life events such as the loss of a spouse or a job may create a happening of depression, many cases come from within, such as people’s diet.

As is reported, both before and during a happening of depression, those with the condition show a “poor appetite”. 2 On the other hand, depression may be closely related to protein. Many cases of depression happen to those who don’t eat properly, which then result in lack of protein taken into the body.

3 It all comes down to amino acids (氨基酸). Proteins are made up of amino acids. Both the human brain and nervous system use amino acids as a substance that creates a signal from one brain cell to another or one nerve cell to another. With them communication between the cells becomes possible.

4 But eight of them, the “essential” ones for communication between the brain cells, must be eaten in one’s diet. So a diet which is lacking in protein lessens the signal being sent from one brain cell to the next during a thought. The process can lead to twisted signals, which can not only lead to depression, but also aggression. 5

A. It happens with aggression.

B. It may lead to serious effects.

C. But how lack of protein occurs?

D. There are 20 different amino acids.

E. But what does protein have to do with depression?

F. The poor appetite itself can create a depressed mood.

G. This is why depression can often express itself as anger or aggression.

【题目】 You may be surprised to learn that English gets 30 to 45 percent of its words from French. The reason goes back to the year 1066, when Norman forces invaded (入侵) what is now Britain. The Normans were from northern France and spoke French. During the Norman occupation, French became the language of England’s rulers and wealthy class. This lasted for more than 300 years. Other people in England continued to speak English during this period.

Over time, the two languages combined and shared words. Some researchers believe that about 10,000 French words eventually entered the English language. However, although English took many French words, their meanings have not always stayed the same. Sometimes the differences in meanings can be very important, and lead to funny or strange situations if the words are used in the wrong way.

Take, for example, the French word college. In English, college can often be used in place of the word university, or sometimes as a school within a university. However, in French, college actually means “middle school”, or the level of schooling for students in grades five or six through eight.

There are many other similar words in the two languages with completely different meanings. In English, the word chat is a verb which means “to talk casually”; but in French, the word chat is the word for an animal: a cat.

If an English speaker says someone is jolly, that means they are cheerful or friendly. But in French, jolie means someone is goodlooking or pleasant to look at. In any case, both are nice things to say to someone.
