Death toll from the 7.0-magnitude earthquake that hit Ya'an in southwestern China's Sichuan Province has risen to 188 (as of 18:00 pm, April 22, ), according to latest calculations by local Civil Affairs Bureau. At least 11,826 were reportedly injured in the quake while 25 are still missing, the bureau said.

Read the following article and select the best answer. Article: Digital technology -- email and smart phones especially--have vastly improved workers' ability to be productive outside of a traditional office. Even so, most white-collar work still happens in an office. One reason is that, according to findings of a new survey of office workers conducted by Wakefield Research for the IT company Citrix, most bosses are doubtful about remote working. Half of the workers say their boss doesn't accept it, and only 35 percent say it's tolerated. Skeptical bosses will likely have their doubts reinforced by the same survey, which shows that 43 percent of workers say they've watched TV or a movie while "working" remotely, while 35 percent have done housework,and 28 percent have cooked dinner. It is true, however, that working at home makes people much more efficient , because it allows workers to take care of annoying housework while still getting their jobs done. It's much faster, for example, to shop for groceries at a quarter to three than to stand in line during the after-work rush. The fact that such practices remain officially unaccepted reflects how far we haven't come as a society from the days when we expected every full-time worker to be supported by a full-time homemaker. More broadly the Wakefield survey suggests that employers may be missing a low-cost way to give workers something of value. Sixty-four percent of those survey participants who haven't worked remotely would rather give up some bonus in order to get even one day a week working from home. Under such circumstances, smart firms need to find ways to let their employees have enough ability to change or be changed easily to suit a different situation to manage their time efficiently. Question: What does the author suggest smart firms do? - Shorten their office hours. - Give employees a pay raise. - Adopt flexible work patterns. - Reduce their staff's workload.
(A).
Adopt flexible work patterns.

Read the following article and select the best answer. Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish. Question: We can infer from the text that dolphins identify others by_. - their looks - their whistles - their smell - their sex
(A).
their whistles
