    Haley’s comet is named for the English astronomer, Edmond Haley, who saw it in 1682Haley knew that people had seen bright lights in the sky in 1531 and again in 1607He did a little mathematics and said the visitor would come back again in 1785He was right. Haley said that in the future, men would travel to the comet and ride it around space!

    For thousands of years books were written by hand. In early printing, each work was hand carved. Few people could ever own books because they were too expensive. For this reason most people never learned to read. The improvements in printing helped make more books. The printers found a way to make moveable type for the printing press. Single letters could then be put together into words and words could be put together to form a page. This method was much easier than hand carving each word of a page. Printers began to print more, and books were more readily available. People began to read.

1Few people could own books because ________.

Athey were owned by kings

Bfew people could read

Dall of the above

2which of the following improvement in printing made books more available.

AMore men were trained as printers.

    When you were born, the bridge between the right and left brain was not fully developedBecause of this all your actions of seeing, hearing and learning came from both sides of your brain. Your two hemi- spheres(半球) were both alike. By the time you were two or three years old, the two sides had developed their own particular tasks. One side of your brain may also have become better than the other at doing certain jobs.

    As you grew older you began to read, write and do maths, which helped make the left brain strong. You may also have spent time with such things as music lessons, art lessons and sports. These all helped to strengthen your right brain. The left and right sides of the brain become stronger after doing these particular tasks. The fact is true for at least ninety- five percent of the population.

    All people, unless they have had brain damaged, have ability to use the right and left hemispheres of their brain. We do, however, have a tendency to be either more right or more left- brained.

1The first paragraph mainly suggests that________

Aas both sides develop, the left side of one’s brain becomes stronger

Bas both sides develop, the head bones become weaker

Cas one grows old, both sides of his brain become more alike

Das one grows old, both sides of his brain become different

2According to this passage ________.

Athe two sides of one’s brain do particular jobs their own at his birth

Bone gets information from both hemispheres when he was born

Cone’s actions of seeing, hearing and learning still come from both sides of his brain at the age of three

Dalmost all the people are left- brained

3It is true for most people ________.

Ato get knowledge by using their right hemi sphere

Bto develop skills by using their left hemisphere

Cthat if he plays musical instruments well the right side of his brain is stronger than ordinary people’s

Dthat it makes no difference to use either the right or left side of his brain

4Which of the following is thought to be discussed after the third paragraph?

AAre you right or left- brained?

BWhat particular jobs does the right side of your brain do?

CWhich are you more interested in, maths or music?

DDo you belong to the group of 95% or the one of 5%?

    Notices have been put up here and there in the village for the last fortnight (两星期) announcing a meeting to discuss the yearly Flower Show, which has not been held in Fairacre for a number of years. Before I became the village school teacher here, the Flower Show appears to have been an event of some importance and people came from miles around to enjoy a day at Fairacre. It was normally held in a field at the side of the church.

Also, with the example of Mr. Annett’s gardening efforts at Beech Green in mind, I had been considering for some time a school garden of our own, and this village show should give our efforts additional encouragement.

    The oldest and hardest cow beef may be made as tender (柔嫩) and tasty as young and choice meat. This declaration was made by the French physicist Denis Papin in his book published in 1681, which described his New Digester or pressure cooker. It was a cast iron pot with an airtight lid, which allowed liquids to boil at a higher temperature than usual, and so it cooked food in a quarter of the time. The food was cooled by pressurized steam being forced through it at about 121℃ . All pressure cookers were made of cast iron until 1905, when the first aluminum() model was made in AmericaIn 1938, Alfred Vischer, a man from Chicago, U. S. A., designed a simple interlocking pan and lid, and an improved pressure - tight seal (密封)—a replaceable rubber sealing ring. When Vischer’s patent(专利) expired in 1954, many companies entered the field, and the rapid pressure cooker became popular with people who had little time to cook or had to supply food for unexpected guests.

1. Which of the following shows the correct order of what happened?

a- Denis Papin called his invention "New Digester".

b- It began to be widely used by common families.

c- Instead of cast iron, it was first made of aluminum.

d - The first pressure cooker was invented in France.

e- Alfred Vischer greatly improved its design.

f - Vischer’s patent came to an end.

g- Many other companies began to produce it.

Ad, a, e, c, g, f, b

Ba, d, c, b, e, f, g

Cd, a, c, e, f, g, b

Dg, c, a, e, d, f, b

2. In the writer’s opinion, the best advantage of a pressure cooker is that ________.

Athe oldest and hardest cow beef can be made tender and tasty

Bit allows liquids to boil at a higher temperature than usual

Cit can help people to supply food for unexpected guests

Dit helps people spend much less time in cooking

3. The best title of this passage would be ________.

   Sharks(鲨鱼) are not as dangerous to humans as humans are to sharks. Even though millions of people swim in the seas each year, fewer than fifty serious shark attacks appear usually, and only ten of these are fatal (致命的). The reason for this low accident rate is that most sharks are afraid of living things as large as humans. Of the350 known kinds of sharks, only one — the great white shark — is totally unafraid of humans. At the same time, humans kill sharks in greater numbers than in the past. Thousands are hunted and killed each year for foodThousands more are killed by the nets under the water, which are put off the beaches to protect swimmers in Australia and South AfricaEven the great white shark is reducing as humans hunt it for its teeth, which are sold to collectors. Maybe it is time we began worrying less about protecting people from sharks and more about protecting sharks from people.

1. The passage mainly tells us that ________.

Ait doesn’t matter if a person is attacked by a shark

Bsharks are not as dangerous as people think

Csharks are afraid of things the size of a human

Dthere are fewer shark attacks than before

2. Nets are put off the beaches in some countries so that ________.

Aswimmers will be safe on the beaches

Bpeople can kill more dangerous sharks

Cpeople can catch sharks easily

Dsharks will not be attacked

3. By writing this passage, the writer wants to give us a warning that ________.

Athe nets off the beaches are killing too many sharks

Btoo many people want to collect shark teeth

Csharks are in danger

Dsharks are still dangerous
