Baby girls make their way directly for dolls as soon as they can crawl, while boys will head for the toy cars,  a study has shown. The findings, the first to show differences in very young babies, suggest there is a biological basis to their preferences.

Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 infants aged nine months to 36 months. The babies were allowed to choose from seven toys. Some were stereotypically boys' toys - a car, a digger, a ball and a blue teddy.  The rest were girls’ toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys, and could pick whichever toy they liked. Their choice and the amount of time they spent playing with each toy were recorded.

Of the youngest children (nine to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two-and three-year-olds, girls spent 50 percent of the time playing with the doll while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents’ view on which toys were more appropriate for boys or girls, and the children’s choice.

Dr Brenda Todd said: “Children of this age are already exposed to much socialization. Boys may be given ‘toys that go’ while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological basis for their choices. Males through evolution have been adapted to prefer moving objects, probably through hunting instincts（本能）, while girls prefer warmer colors such as pink, the color of a newborn baby.”

1.Baby boys and girls have different toy preferences probably because         .

2.Both baby boys and baby girls like to play with       according to the study.

3.What can we infer from Paragraph 3 ?

4.What conclusion did Dr. Brenda Todd draw from the results of the study?

5.We may read this article in a        section of a newspaper.

For centuries, the body's blood has been linked closely with the emotions．People who show no human emotions or feelings, are said to be cold-blooded killer．For example, the police are searching for a cold-blooded killer．He seems to kill for no reason, and no emotion, as if taking someone's life as nothing．

Cold can affect other parts of the body．The expression "get cold feet" has nothing to do with cold or your feet．The expression means being afraid to do something you have decided to do．For example, you agree to be president of an organization．But then you learn that all the other officers have resigned, and all the work of the organizations will be your responsibility．You are likely to get cold feet about being president when you understand the situation．

The expression "give someone the cold shoulder" probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face．You may give a cold shoulder to a friend who has not kept a promise he made to you．Or, to someone who has lied about you to others．

A cold fish is not a fish．It is a person．But it is a person who is unfriendly, unemotional and shows no love or warmth．A cold fish does not offer much of himself to anyone．Someone who is a cold fish could be cold-hearted．Now a cold-hearted person is someone who has no sympathy．Several popular songs in recent years were about cold-hearted men or cold-hearted women who, without feelings, broke the hearts of their lovers．

"Out in the cold" means not getting something that everybody else got．A person might say that everybody but him got a pay raise——he was left out in the cold．And it is not a pleasant place to be．

1.There are _____ expressions related to cold that are mentioned in the passage．

2.When you refuse to speak to a man and treat him in a distant way, you may express by "_____"．

3.If Sue shows absolutely no reaction to those awful pictures of starving children in Africa, you will say ______．

4.We can use the expression "_____" to describe a man who abandons or hurts his lover without mercy．

5.The topic of this passage is about _____．

Cleanse, tone and moisturize: three words that everyone should keep in mind when going through their daily routines. As a society, we decide what are important habits to keep up with, such as taking care of your skin.

It takes a good five minutes every morning and night to properly care for your skin, but most men and women believe that they do not have time in their busy schedule to do so. Having good skin boosts（增加）sef-confidence and improve overall health and attitude.

Cleansing the face is important for women who wear make-up because it clears the face from exposure to free radicals（自由基） in the air. Toning your face is important to balance your skin’s PH level ( which needs to be between 4.5 and 5.5 ) and also to remove the impurities from water, which is full of lead. Finally, moisturizing your face hydrates（增湿）the skin.

In this day and age there are more issues with free radicals that damage your skin than ever before. Smog, UVA/ UVB damage, smoke, alcohol, and more are all negative contributing factors to damaging the aging of your skin.

The global community has advanced the environment into a high percentage of free radical, but we also now have the technology for the best skin care. The issue with skin care is most people feel that you only need to take action if you have a serious skin condition, such as acne(粉刺). But no matter what age and what condition your skin is in, you should actively do something to maintain it.

Most skin care products today are all-natural; many of them advertise being 100 percent vegan（素食）.

Ingredients（成分）that are natural for anti-aging are : DMAE, alpha lapoic acid, antioxidants, collagen booster, SPF and many more. All of these ingredients help prevent aging and sun damage while regenerating new skin cells. Aging appears fastest on your face, neck, and back of the hands and feet, which means you must apply skin care products to all areas. People need to take care of their skin, whether they have a skin condition or not.

If one wants to age gracefully, one must put forth the effort on their skin.

Cities alarmed by deaths and injuries of pedestrians are taking efforts to make crosswalks safer for people on foot, especially seniors and children who need more time to cross streets.

A pedestrian is killed in a traffic accident in the USA every 110 minutes; one is injured every nine minutes, according to official data. Crosswalks can be especially dangerous for the elderly. Among people 70 and older, 36% of pedestrian deaths in 2006 occurred in crosswalks, compared   with 21% of those younger than 70, according to the Insurance Institute for Highway Safety.

The Federal Highway Administration(FHWA) advise that next year states increase by nearly 15% the amount of  time traffic lights provide for pedestrians to cross the street after the flashing orange hand appears.

FHWA spokesman Doug Hecox says reasons for the change include an aging population that needs more time to cross, health-conscious Americans walking more, children encouraged to walk to prevent getting overweight and high gas prices pushing people to walk instead of drive.

Pedestrian deaths went down by 12% from 5,449 in 1996 to 4,784 in 2006, Bur among those in 2006, 471 were killed in crosswalks, down slightly from 488 ten years earlier, the National Highway Traffic Safety Administration(NHTSA) says.

1.Which of the following is true according to the text?

2.What is FHWA’s suggestion to states?

3.What’s the cause of the crosswalk safety problem according to the test?

4.The report from NHTSA suggests that
