By "some people" I mean me. Why is it that an evening stroll(散步)leaves me feeling eaten alive while my companions are left blissfully un-bitten Studies suggest that about 20 percent of people are "high attractor types" who are especially appealing to the female mosquitoes(蚊子)seeking out blood for the extra protein(蛋白质)they need to lay eggs. Of course, not all mosquitoes are the same. But let’ s consider some of the more general properties that affect your mosquito appeal. Clothing Color It’s true, mosquitoes have discerning(有辨识能力的)fashion taste. Or at least, they’re more likely to spot you as a target if you stand out from your environment. Dark colors, especially, will attract more of the insect. Body Heat Visual clues allow the mosquito to locate you from relatively far away, but as she approaches, it’ s your body heat that draws her in. This puts pregnant women, who average about 1.26 degrees Fahrenheit(华氏温度)warmer than others, at a particular risk—a fact which has been substantiated(证实)by a number of studies. Carbon Dioxide This is another reason pregnant women are at a disadvantage. Mosquitoes can detect carbon dioxide using a special organ called a maxillary palp(下颚须)from as far as 164 feet away. Unfortunately for mothers-to-be, pregnancy causes women to emit 21 percent more CO 2 . This is also why kids are often safe from bites, when bigger, more CO 2 -emitting adults are around. Alcohol Intake On the flip side(另一方面), pregnant women are(presumably)avoiding another mosquito attractor: alcohol. Although it’ s unclear how mosquitoes go about detecting the presence of ethanol(乙醇), studies show that drinking even just 12 ounces of beer will significantly increase the attention you receive from the pests. The Properties of Your Skin and Sweat (71) Up to 85 percent of your susceptibility(敏感性)to mosquito bites has nothing to do with what you’ re drinking, wearing or how much heat your body emits—it’ s just genetic. Specifically, the composition of your skin bacteria—the kind that naturally and healthily exists there—can serve as an attractor. Blood Type Another factor you can’ t control Your blood type. And it stands to reason that, if the mosquito is there to suck your blood, she cares what kind she’ s getting. People with blood type O are more prone to mosquito bites than those with type B, with type A folks bringing up the rear.According to the author, which factor below serves as the most influencing one in mosquito appealing

A．Alcohol drinking.
B．Clothing color.
C．The properties of the skin and sweat.
D．The body heat.

单项选择题

It is natural for young people to be critical of their parents at times and to blame them for most of the misunderstandings between them.(72) They have always complained, more or less justly, that their parents are out of touch with modern ways: that they are possessive and dominant: that they do not trust their children to deal with crises: that they talk too much about certain problems— and that they have no sense of humor, at least in parent-child relationships. I think it is true that parents often underestimate their teenage children and also forget how they themselves felt when young. Young people often irritate their parents with their choices in clothes and hairstyles, in entertainers and music. This is not their motive. They feel cut off from the adult world into which they have not yet been accepted. So they create a culture and society of their own. Then, if it turns out that their music or entertainers or vocabulary or clothes or hairstyles irritate their parents, this gives them additional enjoyment. They feel they are superior, at least in a small way, and that they are leaders in style and taste. Sometimes you are resistant and proud because you do not want your parents to approve of what you do. If they did approve, it looks as if you are betraying your own age group. But in that case, you are assuming that you are the underdog(失败者): you can’t win but at least you can keep your honor. This is a passive way of looking at things.(73) It is natural enough after long years of childhood, when you were completely under your parents’ control. But it ignores the fact that you are now beginning to be responsible for yourself. If you plan to control your life, co-operation can be part of that plan. You can charm others, especially your parents, into doing things the way you want. You can impress others with your sense of responsibility and initiative, so that they will give you the authority to do what you want to do.The author is primarily addressing______.

A．parents of teenagers
B．newspaper readers
C．teenagers
D．those who give advice to teenagers

Many visitors find the fast pace at which American people move very troubling. One’ s first impression is likely to be that everyone is in a rush.(74)
< u>City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a brief moment.< /u>
(75)
< u>At first, this may seem unfriendly to you. Drivers will rush you: storekeepers will be in a hurry as they serve you: people will push past you as they walk along the street. You will miss smiles, brief conversations with people as you shop or dine away from home.< /u>
Do not think that because Americans are in such a hurry they are unfriendly. Often life is much slower outside the big cities, as is true in other countries as well.
Americans who live in cities such as New York, Chicago, or Los Angeles, often think that everyone is equally in a hurry to get things done: they expect others to "push back" , just as city people do in Tokyo, Singapore or Paris, for example. But when they discover that you are a stranger, most Americans become quite kindly and will take great care to help you. Many of them first came to the city as strangers and they remember how frightening a new city can be. If you need help or want to ask a question, choose a friendly-looking person and say, "I am a stranger here. Can you help me
Most people will stop, smile at you, and help you find your way, or answer your questions. But you must let them know that you need help. Otherwise they are likely to pass you by, not noticing that you are new to the city and in need of help. Occasionally, you may find someone too busy or perhaps too rushed to give you aid. If this happens, do not be discouraged: just ask someone else. Most Americans enjoy helping a stranger.

Many people who first visit the United States will find that（）.

A、America is a highly developed country
B、American city people seem to be always in a rush
C、the fast pace in American life often causes much trouble
D、Americans are important and unfriendly people
