What if our babies could somehow tell us what they're thinking about, what they want, and what makes them unhappy? Robyn Holt, researcher for Baby Talk New Zealand, says they can. Holt heard about baby sign language through an advertisement and decided to go along to a workshop (研讨会).

    “Sign language is something that's always interested me, and I thought, it could be really cool to try this with a baby because we are always guessing all the time what they actually want.”

    Holt started using baby sign language with her baby son Benjamin, now 12, and within two weeks he started to sign the sign for milk. She has since used it with her two younger sons Dominic, 8, and Matthew, 3.

    Baby sign language is nothing new: the practice (which is based on adult sign language) has been out in America for more than 30 years. But it is enjoying a rebirth in New Zealand.

    The idea behind baby sign language is that babies do have the ability to communicate their needs if they are given the right tools to do so. Although many mothers develop an intuition (直觉) about whether their baby's crying is from hunger, tiredness, or pain, baby sign language creates a direct form of communication that unlocks the mystery.

    When babies are between 6-months and 12 to 13-months, parents can begin to teach them sign language: use the sign for milk while feeding, and also talk about milk, so that the child begins to make the link (关联) in their brain. Then they can begin to add other signs, i.e. food, sick or pain.

    “I know of one parent. Her child was signing the sign for hurt by his mouth, and she realised his first teeth were growing. It makes life so much easier,” said Holt.

    Currently offered by some famous universities, MOOCs are attractive to people who do not have the financial resources to meet the growing costs of university education, or who do not have formal qualifications. They also allow participants to study at their own pace.

    The potential for MOOCs to deliver education is obviously vast—they could be considered as a huge step forwards in widening participation. They also have the potential to provide a unique window on universities that offer popular and valuable courses, they may attract some participants to register for formal fee-paying programmes at the same or other universities and are likely to promote new ways of on-line education.

    However, it is still very early days for MOOCs. The quality of the education provision is highly variable, with many courses offering only recordings of lectures, and delivery is particularly difficult in some special fields that require practical classes, research projects or extensive library access. Besides, wider engagement with participants requires very considerable resource. Even limited feedback or examination becomes a major task if there are several thousand students in the class.

Considering the challenges, some people argue MOOCs will soon evaporate (蒸发). But they certainly provide good opportunity for widening higher education, are a means of raising awareness of universities to audiences of tens or hundreds of thousands, and are well worthy of serious consideration.

    What is your favourite colour? Do you like yellow, orange, red? {#blank#}1{#/blank#} Do you prefer greys and blues? Then you are probably quiet, shy, and you would rather follow than lead． You tend to be pessimist. At least, this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of colour preference, as well as the effect that colours have on human beings.{#blank#}2{#/blank#} If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.

    {#blank#}3{#/blank#} A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day.{#blank#}4{#/blank#} A black bridge over the Thames River, near London, used to be the scene of more suicides(自杀) than any other bridge in the area——until it was repainted green. The number of suicide attempts immediately fell sharply. Perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

    {#blank#}5{#/blank#} It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or grey.

A. On the other hand, black is depressing.

B. They tell us, among other facts, that we do not choose our favourite colour as grow up——we are born with our preference.

C. The rooms are painted in different colours as you like.

D. If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement.

E. Light and bright colours make people not only happier but more active.

F. Life is like a picture or a poem, full of different colours.

G. Colours do influence our moods—there is no doubt about it.

    A food chain is a simple way of explaining how each living thing gets its food. For example, a simple African food chain might consist of three parts: first, trees and bushes; second, giraffes; and third, lions. Each link in a food chain is food for the next link. Food chains always start with plants and end with animals.

    Plants are at the bottom of the food chain. Scientists call them producers, because they use light energy from the sun to produce food from carbon dioxide and water through photosynthesis（光合作用）. Animals, unlike plants, can't produce their own food. Instead, they must eat plants or other animals. This is why scientists call them consumers.

    Consumer animals fall into three categories. Herbivores（食草动物）eat only plants. Carnivores（食肉动物） eat only other animals. Omnivores eat both plants and animals. In addition to producers and consumers, there are also decomposers(分解者).These organisms, such as bacteria and fungi, feed on decaying(腐烂) matter. They help the food chain by speeding up the decaying process that releases minerals back into the soil to be absorbed by plants as nutrients.

    Most food chains have only four or five links in them. As you go up a food chain, the amount of energy at each level diminishes, because some of the energy is lost in the form of waste or is used up by the organism at the level. That is why it takes many plants, for example, to feed a few giraffes who in turn feed one lion.

    Most animals are part of many different food chains, because they must eat more than one type of food to satisfy their energy needs. All of these interconnected food chains form a more complex structure called a food web. Humans, for example, are at the center of a very complex food web, because we tend to eat many different types of plants and animals.
