Have you heard about Leap year? Leap year is a year that has 366 days instead of the usual 365. It normally occurs every four years, always on an even-numbered year. The extra day is added to our shortest month. That is the second month of the year, which in non-leap years has 28 days, two fewer than any other month. 1.

We also call Leap year the bissextile year (闰年). 2. In our calendar system there is a need for a leap year because the solar year (the time it takes the earth to go around the sun once）is actually slightly more than 365 days long. That extra day—Feb 29 every four years—helps correct the difference between our calendar and the solar calendar.

It is said that Leap year was first made part of the calendar by the ancient Roman leader Julius Caesar. His astronomers had calculated the length of the solar year to be 365 days and six hours. So Caesar declared that an extra day be added to the calendar.3.

However, Caesar’s adjustment was not completely accurate because his astronomers’ year exceeded the true solar year by eleven minutes and fourteen seconds. By 1582, a difference of ten days had developed between the calendar year and the true solar year. To correct this error, Pope Gregory XIII ruled that every fourth year would continue to be a leap year except for century years that could not be divided evenly by 400. By this system, century years such as 1700, 1800, and 1900 were not leap years, but the year 2000 was a leap year. 4.

People born on Feb 29 celebrate their growing up a little differently from the rest of us.

5. But if they go strictly by the calendar, they have only one-fourth as many birthday celebrations as most people.

A. They acknowledge that they get older each year.

B. When you see Feb 29 on a calendar, you know that year is a leap year.

C. This is its formal, or scientific title.

D. This may seem complicated, but it works.

E. This is done every four years.

F. The leap year was introduced in the Julian calendar in 46 BC.

G. In a leap year, the extra day is added to the second month, giving it 29 instead of the usual 28 days.

You’ve heard it repeatedly: Make sure you drink at least eight glasses of water per day. The key words are "at least", because, unless you are a child, you need more water than that. The rule is, for every 50 pounds of body weight you carry, drink one quart of bottled or filtered (过滤的) water per day. The average person weighs 150 pounds, so they should drink three quarts per day. A 200 pounds person should drink a full gallon per day. Athletes should drink even more than that. Follow these and you’ve adopted one of the most important health habits.

Our bodies are mostly water, and water is essential to our every function. Drink the appropriate amount, and everything is much more likely to function at the best levels. If you don’t drink enough water, over the short term you will experience tiredness, dry skin, headaches and constipation (便秘); over the longer term, every body function will degrade more quickly. It really is as simple as that.

Things get a bit more complicated in what type of water to drink. Bottled water and filtered water are both good options. Do not drink tap water or distilled water (蒸馏水).Bottled water should be bottled in clear glass containers, not the plastic containers that transfer far too many chemicals into the water. Filtered water can be obtained through low-cost filters.

Tap water should be avoided because it contains chlorine (氯) and may contain fluoride (氟化物), which is poisonous and can have terrible consequences for the body. Distilled water should also be avoided because it can burn up your body of necessary minerals. It has been tied to hair loss, which is often associated with certain mineral lack.

Finally, drink water at room temperature if possible, as ice-cold water can harm your stomach.

1.What’s the meaning of the underlined word “degrade”?

A. Improve.　　　　　　 　　 B. Reduce.

C.　 Strengthen　　　　　　　　 D. Recover.

2.What kinds of water are proper for drinking?

A. Tap water and bottled water.

B. Tap water and distilled water.

C. Bottled water and filtered water.

D. Distilled water and filtered water.

3.What’s the main reason that distilled water isn’t recommended to drink?

A. It leads the body to lack certain minerals.

B. It isn’t clean enough to drink.

C. It contains too many chemicals.

D. It contains fluoride.

4.Which of the following statements is NOT true according to the passage?

A. It is harmful to drink plenty of icy water.

B. One may feel tired due to lack of water for a short time.

C. The water with chlorine is not suitable to drink.

D. The water in plastic containers is safe to drink.

Have you ever heard a news reporter talk about DNA?Reporters talk about DNA found at the scene of a crime.They talk about police finding DNA “fingerprints”.Police sometimes use DNA as a clue to find out who committed the crime.

DNA is a substance(物质)that makes up genes.Everything alive has genes.Plants have genes.Animals have genes.You have genes.

Genes are the basic units of heredity(遗传).Heredity means all the characteristics you inherit from your parents.You get your genes from your parents.You inherit half of your genes from your mother.You inherit half of your genes from your father.

Genes are a kind of code.A tree’s genes tell what shape its leaves will be.A cat’s genes tell what color its fur will be.Your genes tell what color your eyes will be.Your genes tell what color your hair will be.Everything about you comes from the code in your genes.

Genes line up on strands(链)called chromosomes(染色体)in cells.Everything alive is made up of cells.Chromosomes are in the center,or nucleus of cells.

Different parts of you are made of different kinds of cells.Your muscles are made of muscle cells.Your skin is made of skin cells.The code in your genes tells your body to make different kinds of cells.The genes in each cell tell the cell how to work.They tell the cell when to make new copies of itself.

An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants.He experimented with pea plants in the 1860s.One of the things,or traits(特质) Mendel studied was what makes some pea plants tall and some short.He said that the traits must come from units of heredity passed from the parent plants.These units were later called genes.

In the mid-1900s,scientists discovered that genes are made of DNA.In the 1970s,scientists learned how to change DNA with genetic engineering.Scientists also learned that problems with certain genes cause diseases.Muscular dystrophy,cystic fibrosis,and hemophilia are some genetic diseases—diseases caused by problems in genes.Today,scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.

Have you heard about Post Office Cats in Britain? They are mouse hunters. The post office has actually employed cats since 1868. They are not employed to sort or deliver mail, of course, but to protect the mail and keep the population of mice under control. They make sure your morning post arrives free from damages caused by rats and mice.

London post offices were the first to try out the experiment. Within a few months the population of mice had shrunk sharply. Other post offices all over the country were soon using cats in the war against rats and mice as well. Within ten years the pay of the cats was improved from one and a half old pence a day to six or nine pence a day. Now the average rate of pay is about a few pounds a month.

Some of the hard-working cats have become quite famous. In 1980, a cat named Lucky stopped an attempted robbery in a Worcestershire post office on her own. As the two burglars made their way in through the window, Lucky started an attack and they fled empty-handed. Another excellent cat was Jerry, of Earls Court post office in London. He served the building for 16 years and was on duty for 24 hours every day. He drove all the mice away.

However, there are fewer cats employed by the post office than at any time in the past. With the faster movement of the mail and better surroundings, post office cats are not always needed. But many post offices still employ them and they become great friends with the postmen. According to the post office, there is no plan for their services to be discontinued in the foreseeable future.

1.Cats were introduced to British post offices to ________.

A.help sort and deliver mails and papers

B.guard the building against thieves

C.keep mails and papers undamaged

D.search for certain dangers in mails

2.The underlined word “shrunk” in the second paragraph probably means “________”.

A.decreased B.increased C.narrowed D.expanded

3.The cat named Lucky became famous because________.

A.She served the post office for 16 years around the clock.

B.She alone drove two burglars away from the post office.

C.She protected mails from being bitten by mice.

D.She was employed to sort and deliver mail.

4.We may learn from the last paragraph that________.

C.cats are now considered of little use in post offices

D.cats will still be seen in service for quite a long time
