Article: When children learn a language, they learn the grammar as well as words or vocabulary. No one teaches them; children just " _ ". Before babies begin to produce words, they produce sounds. Some of these sounds will remain if they occur in the language being learned, and others will disappear. This is called the "babbling stage". A child does not learn the language "all at once". The child first speaks only one-word "sentences". After a few months, the two-word stage arises. During this stage, the child puts two words together. These two-word sentences have definite patterns and express grammatical and meaningful relationships. Still later, in the telegraphic stage, the child will produce longer sentences. These longer sentences are mainly made up of content words. The child's early grammar lacks many of the rules of the adult grammar, but gradually it will become perfect. All normal children everywhere learn language. This ability is not dependent on race, social class, geography, or even intelligence . This ability is uniquely for human. Question: The phrase "pick them up" means _ . Yes or no, is the answer "learn them without much effort"?
No

Article: "Opinion" is a word that is used carelessly today. It is used to refer to matters of taste, belief, and judgment. This casual use would probably cause little confusion if people didn't attach too much importance to opinion. Unfortunately, most to attach great importance to it. "I have as much right to my opinion as you to yours," and "Everyone's entitled to his opinion," are common expressions. In fact, anyone who would challenge another's opinion is likely to be branded intolerant. Is that label accurate? Is it intolerant to challenge another's opinion? It depends on what definition of opinion you have in mind. For example, you may ask a friend "What do you think of the new Ford cars?" And he may reply, "In my opinion, they're ugly." In this case, it would not only be intolerant to challenge his statement, but foolish. For it's obvious that by opinion he means his personal preference, a matter of taste. And as the old saying goes, "It's pointless to argue about matters of taste." But consider this very different use of the term, a newspaper reports that the Supreme Court has delivered its opinion in a controversial case. Obviously the justices did not shale their personal preferences, their mere likes and dislikes, they stated their considered judgment, painstakingly arrived at after thorough inquiry and deliberation. Most of what is referred to as opinion falls somewhere between these two extremes. It is not an expression of taste. Nor is it careful judgment. Yet it may contain elements of both. It is a view or belief more or less casually arrived at, with or without examining the evidence. Is everyone entitled to his opinion? Of course, this is not only permitted, but guaranteed. We are free to act on our opinions only so long as, in doing so, we do not harm others. Question: The new Ford cars are used here as an example to show that _ . Yes or no, is the answer "personal tastes are not something to be challenged"?
No

Article: "How far is the next village?" the American asks a man standing by the edge of the road. In some countries, because the man realizes that the traveler is tired and eager to reach his destination , he will politely say "Just down the road." He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling "being tricked". He thinks the man on purpose lied to him, for obviously he must have known the distance quite well. Had conditions been reversed , the American would have felt he was "cheating" the driver if he had said the next town was not too far, and if he would be sorry to the weary driver, he would say "You have a good way to go yet, it is at least fifteen miles." The driver might be disappointed, but he would know what to expect. Whether to be accurate or polite leads to many misunderstandings between people of different cultures. If you know the situation in advance, it is sometimes easier to recognize the problem. Question: We can learn from this passage that Americans _ . Yes or no, is the answer "like to be honest and accurate"?
No
