单选题Millions of Americans are entering their 60s and are more concerned than ever about retirement. They know they need to save, but how much? And what exactly are they saving for—to spend more time 26 the grandkids, go traveling, or start another career? It turns out that husbands and wives may have 27 different ideas about the subject. The deepest divide is in the way spouses envisage their lifestyle in their later years. Fidelity Investments Inc. found 41 percent of the 500 couples it surveyed 28 on whether both or at least one spouse will work in retirement. Wives are generally right regarding their husbands' retirement age, but men 29 the age their wives will be when they stop working. And husbands are slightly more 30 about their standard of living than wives are. Busy juggling (穷于应付) careers and families, most couples don't take time to sit down, 31 or together, and think about what they would like to do 5, 10 or 20 years from now. They 32 they are on the same page, but the 33 is they have avoided even talking about it. If you are self-employed or in a job that doesn't have a standard retirement age, you may be more apt to delay thinking about these issues. It is often a 34 retirement date that provides the catalyst (催化剂) to start planning. Getting laid off or accepting an early-retirement 35 can force your hand. But don't wait until you get a severance (遣散费) check to begin planning.

单选题Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earth"s surface, a visitor might assume that the canyon had been caused by some ancient convulsion. In fact the events that produced the canyon, far from being sudden and cataclysmic, simply add up to the slow and orderly process of erosion. Many millions of years ago the Colorado Plateau in the Grand Canyon area contained 10, 000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14-layered formations of rock. In the Grand Canyon region these layers were largely worn away over the course of millions of years. Approximately 65 million years ago the plateau"s flat surface in the Grand Canyon area bulged upward from internal pressure; geologists refer to this bulging action as upwarping; it was followed by a general elevation of the whole Colorado Plateau, a process that is still going on. As the plateau gradually rose, shallow rivers that meandered across it began to run more swiftly and cut more definite courses. One of these rivers, located east of the upwarp, was the ancestor of the Colorado. Another river system called the Hualapai, flowing west of the upwarp, extended itself eastward by cutting back into the upwarp; it eventually connected with the ancient Colorado and captured its waters. The new river then began to carve out the 277- mile-long trench that eventually became the Grand Canyon. Geologists estimate that this initial cutting action began no earlier than 10 million years go. Since then, the canyon forming has been cumulative. To the corrosive force of the river itself have been added other factors. Heat and cold, rain and snow, along with the varying resistance of the rocks, increase the opportunities for erosion. The canyon walls crumble; the river acquires a cutting tool, tons of debris, rainfall running off the high plateau creates feeder streams that carve side canyons. Pushing slowly backward into the plateau, the side canyons expose new rocks, and the pattern of erosion continues.

单选题It is widely known that languages change over the years, and therefore is not easy to estimate how many languages are currently spoken in the world: the figure commonly known is about 5,000. Most languages are known to belong to language families which can be subdivided into smaller units, referred to as branches. There are at least fifteen language families which are the ancestors of modern languages throughout the world. Most languages of Europe except for Basque, Hungarian, or Finnish and the languages of Iran, Afghanistan, Pakistan, and India belong to the Indo-European language family. Four of the five official languages of the United Nations are Indo-European (English, French, Russian, and Spanish are Indo-European). It has twelve branches: Romance, Germanic, Slavic, Baltic, Celtic, Iranian, Indic, Tocharian, Anatolian, Armenian, Greek and Albanian. Germanic group includes English, German, Yiddish, Norwegian, Swedish, Danish, Dutch and a few others. Germanic group shares its similarities in vocabulary and phonology and some are mutually intelligible. With about 350 million speakers, English is spoken in many countries such as the British Isles, the United States, Canada, Australia and New Zealand, being the second most spoken language in the world after Chinese. Romance Group includes French, Spanish, Italian, Portuguese, and Romanian among which Spanish is the third most spoken language in the world. These languages are also closely related to each other. There are various theories about how Indo-European languages came to spread out to Europe and Western Asia, but the most dominant one presumes that the Indo-European language family originated from the Black Sea during the Neolithic period about 7000BC, spreading west to Europe between 3500BC and 2500BC, south to the Mediterranean, north to Scandinavia, and east to India. Scattered throughout Asia and Europe are a few smaller language families among which the Altaic Family is named after the Alti Mountains, in Central Asia where nomadic people lived in the plains. Of the three branches of Altaic, Turkic ranges from Anatolia to the Volga basin and central Asia; Mongolian from China and Mongolia to the lower Volga and Afghanistan; Manchu-Tungus from the northern coast of northeastern Siberia to the Amur and to the Yenisei. Korean and Japanese languages are assumed to be remotely related to the Altaic language family, but it is still controversial. Some scholars consider the Altaic languages are related to the Uralic languages and group them as a larger Ural-Altaic language family, but there has been too little evidence to support this. Included in the Sino-Tibetan family are about 300 East Asian languages, which are divided into a Sinitic Group and a Tibeto-Burman group. The Sinitic group includes a dozen languages among which Mandarin, spoken by about 700 million people in northern China, is the official language of the Peoples Republic of China. The Tibeto-Burman group includes many rarely spoken languages, among which are Burmese and Tibetan. The Sino-Tibetan language family has the largest number of speakers, estimated to have 1 billion speakers. In addition to the three above mentioned language families, there are other language families such as the Austronesian family, the Afroasiatic family, the Uralic family, the Malayo-Polynesian family and the Caucasian family. A very large majority of the people in the world speaks languages which belong to only one family. There are, however, also languages that cannot be classified into any family known as language isolates.

单选题Train companies in Tokyo are taking action to reduce the number of people jumping in front of trains. They are fitting blue lights on station platforms to try and create a more calming atmosphere. The East Japan Railway Company has invested almost $170,000 to install the lights in all of the 29 stations on the capital's busy Yamanote Line. There has been an alarming rise in the number of people committing suicide at train stations. A total of 68 people threw themselves under trains in the year up to March. This compares with 42 suicides in the same period a year earlier. In 2008, Japan had nearly 2,000 suicides by jumping in front of a train; around six percent of all suicides nationwide. Suicides have risen sharply in the past decade due to poor economic conditions. No one knows if the blue lights will work. There is no evidence to show that blue light reduces suicidal feelings. Keihan Railway spokesman Osamu Okawa stated: "We thought we had to do something to save lives. We know there is no scientific proof that blue lights deter suicides, but if blue has a soothing effect on the mind, we want to try it to save lives." The Associated Press news agency reports on a Japanese therapist called Mizuki Takahashi. She explained her reasons why the blue lights might be a good idea: "We associate the color with the sky and the sea. It has a calming effect on agitated people, or people obsessed with one particular thing, which in this case is committing suicide," she said. Other companies are watching this experiment with interest.
