Do you know how important it is to have breakfast? A study of 2,000 teenagers in the US showed that eating breakfast daily is helpful to young people.
According to the study, teenagers who eat breakfast weigh around 5 pounds less than teenagers who do not. Although they take in more calories (卡路里) in the morning, they are more active during the day because they have more energy. This means they burn more calories than non-breakfast eaters. The breakfast does not even have to be very healthy, as eating anything is better than nothing.
The study also showed that eating breakfast keeps teenagers feeling full for longer, so they will not eat too many snacks (零食) later in the day. This is good news as most popular snacks, like sweets and potato chips, are usually unhealthy and full of calories.
Another big advantage of eating breakfast is that it helps teenagers do better at school.This is because it gives them more energy to keep their attention in class.
What's more, a study in the UK showed that adults (成年人) who eat breakfast daily put on less weight and also perform better at work.
Whatever your age is, take time to have breakfast every day.

For Zhang Xiaomeng, a senior high school girl from Jiangsu, meeting her best friend Hua Xuan was the best part of her time at junior high school.

Then one day, he was told: “The exam is in 100 days.” “We need a strong knowledge base to pass the exam. But I didn’t care about it,” said Zhang.

According to scientists' research, the month in which babies are born could affect them in some ways.
Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn  Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy(懷孕).  Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.
Vitamin D, called the "sunshine vitamin", is known to help regulate（調(diào)節(jié)） thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health  This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.
Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth."
小題1:A baby's season of birth doesn't affect its_______.
A．healthB．heightC．length of lifeD．mind
小題2:According to the passage,_______ can help people get Vitamin D.
A. enough sleep                B. enough sunlight   
C. fresh air                        D. suitable seasons
小題3:Which of the following is TRUE according to the passage?
A．People born in spring may not be in good health.
B．Children born under Aquarius are cleverer than those born under Libra.
C．Professor Russell Foster is interested in star signs and believes in them
D．People born in May will live longer than those born in October.
小題4:What does the passage mainly tell us?
A. People can know the length of life by star sign.
B. Women should choose to give birth to children in spring.
C A child's season of birth has some effect on him or her.
D. Vitamin D is very important to people's health.

Why do people love pandas so much? Perhaps it is because they look very cute, or perhaps it is because there are not many left.

Pandas are actually called giant pandas. Many people also call them panda bears because they are mammals (哺乳類) classified from the bear family. Giant pandas originate in China. Pictures of both the dragon and the giant panda are often regarded as the symbols of China.
Giant pandas look different from other bears because they are white with black patches around their eyes, over their ears, and across their bodies. Although they look adorable and move slow, they can be as dangerous as any other bear when they are angry. Pandas mostly eat bamboo, but they may also eat other food like eggs, fish, oranges and bananas.

Many people think that giant pandas have few babies, and that is one of the reasons that there are not many of them left. But scientists say that a female panda may have about five or six cubs during her life. The female panda gives birth to one or two panda cubs, but she is only able to take care of only one of her cubs. As a result, one of her cubs dies soon after birth because of a lack of intense care.
The giant panda is an endangered species, and there are only about 2,000 giant pandas left in the world. People have been trying hard to protect giant pandas. It looks like their work is paying off because the number of giant pandas is increasing.
小題1:Why do some people call “pandas” panda bears?
A．Because they look like bears.
B．Because they like to live with bears.
C．Because they are often regarded as bears.
D．Because they are mammals classified from the bear family.
小題2:What do pandas like eating most?
A．Bamboo.B．Fish.C．Bananas.D．Oranges.
小題3:How many baby pandas can a female panda have in her life?
A．Three.B．Four or five.C．Five or six.D．More than seven.

Wang Jiaming from Beijing Chenjinglun High School says he is a lucky boy. He’s happy that he’s sitting the senior high school entrance exam (中考) in 2014 instead of 2016.
On Oct 22, Beijing Municipal Commission of Education (北京市教委) announced that, from 2016, the English scores in the senior high school entrance exam will be reduced from 120 to 100. Of the 100 points, the listening ability scores will increase to 50. Meanwhile, the points for Chinese will increase from 120 to 150.
“The change won’t affect me. I feel so lucky because English is my strongest subject,” said Wang.
Why such a change? It places the importance on Chinese in our study, and reduces students’ stress, said Li Yi, spokesman of the commission.
“The change will also push us to pay attention to the practical usage (運用) of English,” said Li. “Students will be encouraged to learn to understand English menus and read English news on mobile phones.”
There isn’t news that other cities will have the same change. But several places are making changes to English tests in the college entrance exams. For example, Shandong is considering taking out the listening part of the English exam in its college entrance exams.
But, “being tested for less points doesn’t mean the subject can be taken lightly,” Bai Ping wrote in China Daily.
English has long been the world’s most commonly used language. Former Chinese premier Zhu Rongji once said: “In a globalizing economy (全球經(jīng)濟), if you cannot communicate with foreigners, how can one be part of the world economy?”
Wang Jiaming said he understood the change.
“Chinese, not English, is our mother tongue (母語),” he said. “But still, I think English is both interesting and useful.”
小題1:In the Beijing senior high school entrance exam of 2016, _____.
A．the English scores will be cut down to 100
B．the English listening ability scores will be lowered
C．the points for Chinese will be reduced by 30 points
D．the points for chemistry will increase by 20 points
小題2: The underlined phrase “can be taken lightly” in this sentence “being tested for less points  doesn’t mean the subject can be taken lightly,” is closest in meaning to “_____________”.
A．can be taken out
B．can be paid less attention to
C．can be taken a close look at
D．can take the place of Chinese
小題3:What is the main purpose of the change?
A．To encourage students to learn how to order meals in English.
B．To make students learn to read English news on mobile phones.
C．To ask students to prepare for the college entrance exam.
D．To make students pay more attention to learning Chinese.
小題4:What does Bai Ping think of the reforms (改革)?
A．They make students spend less time on English.
B．They make it harder to get a high score.
C．Studying English is still important for the students.
D．English is both interesting and useful.

The world would be a very different place if someone hadn’t invented the lift. There would be few, if any, high-rise buildings because people would refuse to climb many stairs. By the time workers reached their offices on the top floors of a tower building, it would be time to go home – if they were not too tired for the long walk down！

The first lift that we know about was used by the Greek scientist, Archimedes, in about 230 BC. It was a simple place that could be pulled up and down with a rope. A lift like this was used much later in the 12th century by priests who lived on top of a mountain at Metereo in Greece. Because they were afraid of killers, the priests had not built any stairs up the mountain. The only way up was by lift, which priests worked from the top of the mountain.
A few hundred years later, a Frenchman, Villayer, invented a ‘flying chair’ which used a rope and a place. A number of rich people had these ‘flying chairs’ built in their homes, including Queen Anne of England in Windsor Castle and Louis XVI of France at Versailles. Unluckily, Louis’ daughter was badly hurt when using one of the chairs, and Villayer ran away, afraid that he would be punished.
The main problem for lift engineers was that either humans or animals were needed to pull the ropes. This problem was not worked out until the discovery of steam power. But even steam powered lifts were not always safe because they also used ropes which sometimes broke. If the rope broke - which it sometimes did - the lift fell to the ground and people in it were killed or hurt. This problem worked out in 1854 when an American, Elisha Otis, invented something which stopped the lift from falling if the rope broke. At first Otis lifts were used only in factories, then in 1857 he built one in a large New York store. Now lifts use electric power and are completely safe. They also travel very quickly. Some lifts travel faster than 60 kilometers an hour.
小題1:The writer thinks that lifts are important today because __________.
A．people like playing on them
B．they are the best way of using steam power
C．we need them for tall buildings
D．workers are lazy
小題2:The 12th century priests had a simple lift instead of stairs because ___________.
A．they thought the stairs were broken
B．they liked having stairs and a lift
C．the lived at the bottom of a mountain
D．they were afraid of killers
小題3:Villayer thought he would be punished because ____________.
A．poor people could not afford his ‘flying chair
B．someone was hurt in one of his ‘flying chairs’
C．his ‘flying chair’ did not work at all
D．he ran away with Louis XVI’s daughter
小題4:Steam power meant that ________  .
A．they did not need a living thing to pull the ropes
B．Elisha Otis could invent a lift that would not fall
C．the rope always broke
D．they could use lifts in factories
