A controversial new study has claimed that men really are more intelligent than women．The study concluded that men’s IQs are almost four points higher than women’s.

British-born researcher John Philippe Ruston says the finding could explain why so few women make it to the top in the workplace.

He claims the “glass ceiling” phenomenon is probably due to inferior intelligence，rather than lack of opportunity.

The University of Western Ontario psychologist reached his conclusion after scrutinizing the results of university ability tests taken by 1 00,000 students aged 17 and 18 of both sexes.

A focus on the factors such as the ability to quickly grasp a complex concept，verbal reasoning skills and creativity― some of the key factors of intelligence ―showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100.The findings，which held true for all classes and levels of education, overturn 100 year opinion that men and women average the same in general mental ability. They also conflict with evidence that girls do better in school exams than boys.

But Professor Ruston argues that the faster maturing of girls leads to them outshining boy in the classroom.

1. The report is mainly about ______.

2. The underlined word “scrutinizing” in the fourth paragraph probably means ______.

3. We can infer that the average woman has an IQ of ______.

 Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear.__ 1.__. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.

Both systems use the freezing and boiling points of water as their guide.__ 2.___.

The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.__ 3._.

First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.____ 4.___.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily. ___5.____.

As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A．People use thermometers which are made by themselves when travelling around the world.

B. We use and depend on thermometers to measure the temperature of many other things in our daily lives.

C．Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

D．Now that you know this rule you can make a thermometer of your own that will work.

E．The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

F．They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.

G．Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal(把..粘住) them together.

One sunny afternoon, a seven-year-old girl went for a walk. She crossed a large area of grassland into the woods __31__ she realized that she was lost.
Sitting on a rock and __32__ what to do, she began crying. After a while, she__33__ to walk along a wide path lined with tall trees and thick bushes. __34__ it was getting dark, she saw a small, dark wooden house. She opened the door and __35__ stepped in. Suddenly, she heard a strange noise, and she ran out the door and back to the __36__. Cold and tired, she fell asleep near a __37__.
The girl’s parents were out and her dog, Laddy, was at home. Laddy __38__ that his Mistress was in danger. He jumped __39__ a window, breaking the glass. He looked in the fields. But he couldn't find his mistress anywhere. However, from the ground came a __40__ scent as he lowered his head. He __41__ the scent and walked across the grassland. Barking __42__ into the air, the dog __43__ through the woods until he found the __44__ . But the girl was not there, so he headed back to the woods. Much to his __45__ , he saw his mistress’ blue shirt in the distance. He __46__ over some bushes and saw the little stream, where the girl was __47__.
When she opened her eyes and   48  her dog standing beside her, the girl said, “you   49   me, Laddy,” and she kissed him several times. Seeing their daughter and dog coming back, the parents burst into tears of     50 . That night Laddy had a Hero's supper: a huge meal of steak.

Put an ice cube from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.

You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.

First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze again.

After a minute or two you may raise the piece of string and with it you will raise your piece of ice!

This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.

61. We must use _______ when we carry out this experiment.

A. fridge             B. some food                   C. a table     D. some salt

62. How long will it take to carry out this experiment?

A. More than three minutes.           B. Five minutes or so.

C. Only one minute or two.               D. About ten minutes.

63. What is the task of this experiment?

A. Put the ice cube into the glass of water with the help of the string.

B. Take out the ice cube in the glass of water with the help of the string.

C. Take out the ice cube in the glass of water with your fingers.

D. Put some salt on the ice cube and then put the string across it.

64. How many things at least are used in this experiment?

A. Three.              B. Four.                    C. Six.                  D. Seven.

65. We can learn something about _______ from the passage.

A. physics          B. biology         C. chemistry        D. maths

The worst earthquake in 40 years shook South Asia on Sunday, starting with horrible waves that swept entire villages into the sea. At least 20,000 people in six countries were killed in the disaster, and millions were left homeless.

The quake shook deep beneath the Indonesian island of Sumatra. It was felt more than 3000 miles away in East Africa, where heavy tides kept fishermen at home and resorts（度假胜地）closed.

It was as if the sea had struck the land. Residents of Sri Lanka, a small island country off the coast of India, ran to the hills to find safety from the tsunami. Many took their radios, televisions, and other valuables with them. The disaster hit Sri Lanka hardest. Of its 20million people, 1 million lost their homes, and 10000 died.

“The water simply raised itself up and huge waves came ashore,” wrote eye-witness（目击者）Peter Thomas from India. “It was moving very fast. The force broke the glass walls of a restaurant on the beach here and damaged hundreds of boats.”

In some places, the tsunami struck with no warning. “The weather was fine with no clouds,” wrote an eye-witness in Indonesia. “Suddenly the seawater just hit the city. In some parts the water was up to chest level.”

A massive（大众的）effort to help the affected countries is already underway. Leaders from around the world have promised to help, and teams of aid workers and doctors are rushing to the sea. “The United States stands ready to offer all the help to those nations most affected.” Said White House spokesman Trent Duffy. Organizations from the Red Cross to the International Monetary Fund have started fund-raising（筹款）drives to make up the costs of rebuilding.
