One of the greatest biologists the world has ever seen was Charles Darwin. Darwin was born to a middle-class family in Shrewsbury, England, in February, 1809. His father was the leading doctor of the town.
1. He loved to walk through the woods looking at plants and birds. At the proper age, he was admitted into Shrewsbury School. There he studied Latin, classical literature, and ancient history. Young Charles thought that these subjects were dull and useless. He would have preferred scientific studies. 2.
In 1825, at the age of sixteen, Darwin was sent to Scotland to study medicine. He studied there for two years and continued to do poorly. He once wrote to his sister that his medical courses were completely stupid. By then, Darwin’s father knew that his son would never become a doctor.
Darwin’s father then sent him to Cambridge to become a clergyman (牧师). During his Cambridge years, Darwin loved to collect beetles(甲虫), but to him it was only a hobby. He didn’t take it seriously. 3. That was Professor John Henslow, the head of the Botany Department.
Somehow, Darwin managed to graduate from Cambridge in 1831. Upon graduation, Professor Henslow arranged for him to go with Captain Fitzroy on a survey trip around the world. During the voyage, Darwin collected rocks, bones, and insects. He took many notes on all that he observed. 4.
The widely believed theory in those days was that God created each creature separately and individually. In 1859, Darwin published his famous book, The Origin of Species. 5. The theory was instantly and very strongly attacked. Darwin was accused of destroying religion and insulting (侮辱) the human race. Today, however, Darwin’s theory is considered to be one of the major discoveries of modern science.
A. As a result, he did poorly.
B. One person at Cambridge, however, did.
C. As a boy, Darwin showed a great interest in living things.
D. In it, he explained his theory of evolution by natural selection.
E. Shrewsbury was a busy market town surrounded by rich farmlands.
F. The thoughts that led to his theory of evolution were beginning to form.
G. By the time Darwin died in 1882, he was recognized as one of England's greatest scientists.
Life is not easy in senior high school. You’ve got the pressure of studies and exams.
From time to time, you may feel depressed and frustrated. When depression strikes, you have to take measures to fight it. One of the strangest ways to fight depression is to eat salt, scientists have found.
Salt acts as a natural anti-depressant (抗抑郁剂), researchers say. While too much can lead to high blood pressure and heart disease, not enough can cause “psychological(心理的) depressions”, a study has reported.
The study, by researchers at the University of Iowa in the US, discovered that when rats are deficient in salt, they don’t do activities they normally enjoy.
The recommended daily salt intake for an adult is four grams, although experts say the body needs only half as much.
However, most adults in the developed world consume（消耗）around ten grams a day, mainly because their diets contain high salt amounts. Today, 77 percent of US salt intake comes from processed and restaurant foods, like frozen dinners and fast food.
The minerals in salt are required by the body—in small quantities—to help move liquid in and out of cells. But too much can cause diseases, for example high blood pressure.
Today scientists are finding that salt is an addictive substance—almost like a drug.
One sign of addiction is using a substance even when it’s known to be harmful. Many people are told to eat less salt due to health concerns, but they have trouble doing so because they like the taste and find low-salt foods tasteless.
Humans have a long history of eating salt. In the Stone Age, people didn’t need to find salt, because they hunted most of their food, and ate a lot of red meat, which has plenty of salt in it. But when people began to farm, about 10,000 BC, they started to eat mainly grains like rice and wheat, and very little meat. Then they had to find another way to get salt.
1.What does the underlined word "deficient" in the fourth paragraph mean?
A. enoughB. far from enough
C. more than enoughD. plenty
2.The major role of salt is to ________.
A. help the body work well
B. help fight against depression
D. help people get rid of an addiction to drugs
D. help people enjoy sugary substances
3.Which of the following statements is true?
A. People have trouble reducing salt because they don't know it is harmful to eat too much of it.
B. Before 10,000 BC, human beings did not need salt.
C. The richer the country is, the more salt is eaten there.
D. Taking more than 4 grams of salt a day can be harmful for an adult's health.
4.What kind of food should people eat more of?
A. Frozen foodB. Fast food
C. Red meatD. Low-salt food
