Travel is exciting and summer is a busy period for holiday travel. Many people will travel great distances in airplanes, cars or other vehicles. Experts say people should know about other health problems that can strike when traveling by air.
One of these is a condition called hypoxia (缺氧症). It results from a lack of oxygen to the brain. Experts say the body begins losing oxygen minutes after an airplane leaves the ground. The air pressure in a plane during flight is lower than at sea level. This makes it more difficult for the body to effectively use the same amount of oxygen as it would on the ground. Fewer oxygen molecules （分子） cross the tissues (组织) in the lungs and reach the bloodstream.
The result is a five to twenty percent drop in the amount of oxygen in the blood. This reduces the amount of oxygen that reaches the organs of the body.
One effect of this lack of oxygen to the brain is a headache. When this happens, the heart attempts to fix the situation by beating harder and faster. This can make the traveler feel tired.
These signs of hypoxia are not dangerous in a healthy person. But a drop in oxygen level can cause a health emergency in people with heart or lung problems. They might lose consciousness or even suffer a heart attack.
Experts say that smoking cigarettes and drinking alcoholic liquids also reduce the body’s ability to use oxygen. So they suggest that people not drink alcohol or smoke cigarettes either before or during a flight. They also say persons with heart or lung problems should seek advice from their doctors before flying.The author writes the passage mainly to ___.

On October 11, NASCAR announced the car of tomorrow after a seven-year design program. People used to believe that science would promise a future of endless spare time and very cheap electricity. Nowadays the scientists’ predictions are a great deal less optimistic: the world is challenged by climate change and decreasing resources.
In fact, the car of tomorrow is a symbol of hope. The emission of carbon dioxide has contributed to global warming, but the car producers are waking up to their responsibilities. Investment in new technology to maximize efficiency and minimize environmental damage is not only improving the car industry’s act but also setting an example to other industries.
It is said that most cars of today run about 15 percent efficiency, which does highlight the potential for improvement. Get it right, and we could continue to enjoy the freedom that comes with owning a car, without the worries.
Of course, many advances have already been made. There’s evidence that the public is eager to buy cleaner and greener cars. And with petrol prices increasing there is no doubt that the cars with economical, efficient engines are going to be in great demand.
The good news is that we can all drive the car of tomorrow today, without having to worry about the purchase cost. By choosing our holiday hired cars wisely we can cut down on our fuel costs and experience an eco-friendly drive. Hire a green car and you’ll make a difference to the environment.
Designers will always enjoy catching our imagination with “concept cars” that look more like miniature(微型) spaceships than anything you see on the highway. Whether these creations will eventually become family cars remains to be seen. However, for the moment, there’s no doubt at all what the car of tomorrow will be, and it’s here today: something familiar and friendly that does its job with considerably less trouble and much greater efficiency than the car of yesterday.The writer of the text intends to ________.
| A．suggest | B．inform | C．approve | D．instruct |

| B．new cars cost less to maintain |
| C．cleaner and greener cars are in great demand |
| D．no measures have been taken to improve car quality |
What is the author’s attitude towards the cars of tomorrow?
| A．Indifferent. | B．Negative. |

Strange Baby-Naming Laws
Germany
Parents are banned by law from using last names and the names of objects and products as first names. A child’s first name must clearly show his or her sex, and all names must be approved by the office of vital statistics(人口统计) in the area in which the child was born.
Iceland
The country’s naming committee consults the National Register of Persons to determine if a name is acceptable. If parents prefer a name which is not on the list, they must apply for approval and pay a fee, and the name must contain only letters in the Icelandic alphabet.
New Zealand
The country’s Births, Deaths, and Marriages Registration Act of 1995 doesn’t allow parents to choose a name that “might cause offense to a reasonable person; is unreasonably long; or is, includes, or is similar to an official title or rank,” including, apparently, Adolf Hitler and Yeah Detroit—both names recently rejected.
Denmark
If Danish parents prefer a name not on the list of 7,000 preapproved baby names, they must get permission from local church and government officials. 15 to 20 percent of the 1,100 reviewed names—including creative spellings of common names, last names as first names, and unusual names—are rejected each year.You can tell whether a baby is a girl or a boy according to the first name in ________.

A fierce earthquake struck Haiti onJanuary 12, 2010, causing a crowded hospital to fall down and countless houses and buildings were destroyed.
The earthquake, the worst in the region in more than 200 years, with a magnitude estimated at 7.0, struck just before 5 p.m. about 10 miles southwest of Port-au-Prince, leaving the region nearly in ruins. As night fell in Port-au-Prince, Haiti’s capital, fires burned near the shoreline downtown, but otherwise the city fell into darkness. The electricity was out, telephones were not working and relief workers struggled to make their way through blocked streets.
In this earthquake, it was not possible for officials to determine how many people had been killed and injured. It was reported that the headquarters of the United Nations mission was seriously damaged and many employees were missing. Part of the national palace had fallen to the ground. A hospital was totally ruined in Pétionville, which is home to many diplomats（外交官） and wealthy Haitians. A New York reporter said that a wall at the front of the Hotel Oloffson had fallen, killing a passer-by. A number of nearby buildings was badly damaged, trapping people. People were screaming, calling for help from every corner.
Haiti sits on a large fault between the much larger North American plate to the north and the Caribbean plate to the south. The earthquake on Tuesday happened when what appears to be part of the southern fault zone broke. With many poor people living in tin-roof shacks(窝棚) and with many of the buildings in Port-au-Prince and elsewhere in the country of questionable quality, it was expected that the quake caused major damage to buildings and great loss of life.What was the damage of the earthquake?
| A．The headquarters of the UN mission was totally destroyed. |
| B．Some of the national palace had fallen to the ground. |
| C．A hospital was partly ruined in Pétionville. |

| B．Haiti covers the entire geographic plates of the earth |
| C．the earthquake caused the southern fault zone to break |
| D．a grand hotel was completely ruined in Pétionville |

MOOCs, short for “massive open online courses,” mark an important, possibly revolutionary, development in education. These courses are on line, free of charge, and open to anyone in the world who has a laptop and an Internet connection. Moreover, they are mainly offered by great universities like Stanford, Berkeley, Harvard and Columbia.
The courses are arranged according to how difficult they are, enabling students to progress from beginners to the advanced. The courses cover not only a broad range of science subjects such as math and computer science, but also courses in social sciences and humanities. Though MOOCs are not offered for credit and degree, many students enroll(加入) in the courses for real skills or knowledge which they can put to some practical use.
The format(形式) seems better than the traditional school class. The average quality of the lecturers is much higher. Besides, students can learn back and forward－that is, they can go at their own learning speed, which they can’t do in a live lecture. And, more importantly, they don’t have to travel anywhere to attend an online lecture. There is a problem of asking questions of the lecturer in a class of ten thousand students, but some MOOCs have solved it by allowing students to post questions on line for a vote, and only the most popular questions are put to the lecturer.
In a knowledge age, lifelong learning is not confined to a traditional classroom. Students taking MOOCS are usually very clever, have work experience, and in many cases, have already developed a set of practical skills. Moreover, they also offer unique international perspectives(远景) that would be the envy of any school classroom.Which of the following statements is NOT true about MOOCs?
| A．The word “MOOCs” is short for “ massive open online campuses”. |
| B．Anyone who has a computer and an Internet connection can take MOOCs. |
| C．MOOCs are usually offered by first-class universities in the world. |
| D．MOOCs may be a breakthrough in the development of education. |
MOOCs seem to have an advantage over traditional school classes in that ________.
| A．there is a problem of asking questions in traditional classes |
| B．students enrolling in MOOCs can get credit and degree easily |
| C．students can learn at their own study pace |
| D．students can travel to many places when taking MOOCs |
The meaning of the underlined word “confined” means ________.
| A．extended | B．developed |
| C．limited | D．advanced |
