单选题{{B}}Text 2{{/B}} Caution seems the watchword among the institutional investors surveyed in our latest portfolio poll. The allocation of money between equities, bonds and cash has. on average, remained at the same levels as it did during the third quarter. While Lehman Brothers and Commerz International have increased their overall equity allocations. Daiwa has increased its bond allocation. But given the slowdown in the American economy, it is the reaction of our investors to American equity holdings that is worthy of note. While three of them. including Lehman Brothers, take a dim view of the prospects for American shares, the other four have either marginally increased their allocations, or have maintained them at the same levels as in the previous quarter. Lehman Brothers seems to have decided that the prospect for German shares is better than it is for American ones. Its allocation for American equities dropped by seven percentage points, to 45% of its equity holdings; while its German share portfolio increased by six percentage points, to 11%. Lehman's share allocation to America has dropped, even as its overall equity holdings have increased. Daiwa and Standard Life are the other two that have cut back on American equities. But Credit Suisse continues to be a cheerleader for American shares. Following its ten percentage-point increase in the third quarter, the Swiss firm increased its exposure to American equities once again in the fourth quarter. Commerz International appears to share Credit Suisse's bullish outlook: its American equity holdings have increased by four percentage points, to 490. Julius Baer is extremely bullish on American equities, with 60% of its equity funds parked there. But the average American equity holdings, among our institutional investors dropped by a percentage point in the fourth quarter. British equities seem to have become attractive—all our investors have increased their allocations. Credit Suisse, which in the third quarter cut its investment in British shares, appears to have changed its mind. It has increased its allocation by four percentage points, taking the total to 9%. On the other hand. Japanese shares have been given the thumbs-down: all our investors save Julius Baer (unchanged) and Credit Suisse (slightly up) have moved funds out of Japanese equities. It is a relatively similar story for Japanese bonds, where everybody apart from Commerz International has either dropped their yen-denominated bond holdings, or kept them unchanged. Robeco Group seems decidedly bearish, for it has sharply, cut its allocation, from 24% to 15%. Lehman Brothers. appears to have got the timing right, by raising its allocation of dollar-denominated bonds in the fourth quarter. Its increase was followed by the Fed interest-rate cut on January 3rd. Will Lehman's bearish timing prove right for American shares, too?

单选题Most people think of lions as strictly African beasts, but only because they"ve been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that spit from African lions perhaps 100,000 years ago, hang on to an almost impossibly small slice of their former territory. India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile sanctuary (保护区). It took me a year and a half to get a permit to explore the entire Gir Forest—and no time at all to see why these lions became symbols of royalty and greatness. A tiger will hide in the forest unseen, but a lion stands its ground, curious and unafraid—lionhearted. Though they told me in subtle ways when I got too close, Gir"s lions allowed me unique glimpses into their lives during my three months in the forest. It"s odd to think that they are threatened by extinction; Gir has as many lions as it can hold—too many, in fact. With territory in short supply, lions move about near the boundary of the forest and even leave it altogether, often clashing with people. That"s one reason India is creating a second sanctuary. There are other pressing reasons: outbreaks of disease or natural disasters. In 1994 a serious disease killed more than a third of Africa"s Serengeti lions—a thousand animals—a fate that could easily happen to Gir"s cats. These lions are especially vulnerable to disease because they descend from as few as a dozen individuals. "If you do a DNA test, Asiatic lions actually look like identical twins," says Stephen O"Brien, a geneticist (基因学家) who has studied them. Yet the dangers are hidden, and you wouldn"t suspect them by watching these lords of the forest. The lions display vitality, and no small measure of charm. Though the gentle intimacy of play vanishes when it"s time to eat, meals in Gir are not necessarily frantic affairs. For a mother and her baby lion sharing a deer, or a young male eating an antelope (羚羊). There"s no need to fight for a cut of the kill. The animals they hunt for food are generally smaller in Gir than those in Africa, and hunting groups tend to be smaller as well.
