③ 关于介绍防晒霜的英语
Sunscreen (also known as sunblock, suntan lotion) is a lotion, spray or other topical proct that helps protect the skin from the sun's ultraviolet (UV) radiation, and which reces sunburn and other skin damage, ultimately leading to a lower risk of skin cancer. However, suntan lotion is an incorrect term for sunscreen as it is something entirely different. Suntan lotion is used to moisturize and maximize UV exposure and tanning, rather than block it. These are commonly called indoor tanning lotions when designed for use with tanning beds or just suntan lotion if designed for outdoor use and may or may not have SPF protection in them.
The best sunscreens protect against both UVB (ultraviolet radiation with wavelength between 290 and 320 nanometres), which can cause sunburn, and UVA (between 320 and 400 nanometres), which damages the skin with more long-term effects, such as premature skin aging. Most sunscreens work by containing either an organic chemical compound that absorbs ultraviolet light (such as oxybenzone) or an opaque material that reflects light (such as titanium dioxide, zinc oxide), or a combination of both. Typically, absorptive materials are referred to as chemical blocks, whereas opaque materials are mineral or physical blocks.
Dosing for sunscreen can be calculated using the formula for body surface area and subsequently subtracting the area covered by clothing that provides effective UV protection. The dose used in FDA sunscreen testing is 2 mg/cm².[1] Provided one assumes an "average" alt build of height 5 ft 4 in (163 cm) and weight 150 lb (68 kg) with a 32 in (82 cm) waist, that alt wearing a bathing suit covering the groin area should apply 29 g (approximately 1 oz) evenly to the uncovered body area. Considering only the face, this translates to about 1/4 to 1/3 of a teaspoon for the average alt face.
Contrary to the common advice that sunscreen should be reapplied every 2– hours, research has shown that the best protection is achieved by application 15–30 minutes before exposure, followed by one reapplication 15–30 minutes after the sun exposure begins. Further reapplication is only necessary after activities such as swimming, sweating, and rubbing.[2]
However, more recent research at the University of California indicates that sunscreen needs to be reapplied within 2 hours in order to remain effective. Not reapplying could even cause more cell damage than not using sunscreen at all, e to the release of extra free radicals from absorbed chemicals.[3]

The principal ingredients in sunscreens are usually aromatic molecules conjugated with carbonyl groups. This general structure allows the molecule to absorb high-energy ultraviolet rays and release the energy as lower-energy rays, thereby preventing the skin-damaging ultraviolet rays from reaching the skin. So, upon exposure to UV light, most of the ingredients (with the notable exception of avobenzone) do not undergo significant chemical change, allowing these ingredients to retain the UV-absorbing potency without significant photo-degradation.[1]

原文地址： is a beautiful day,but I can't see it！(美好的一天，可是我什么也看不见)作者：李雪华
A blind boy sat on the steps of a building with a hat by his feet. He held up a sign which said, “I am blind, please help.”
There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words.
Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy heard his footsteps and asked, “Were you the one who changed my sign this morning? What did you write?”
The man said, “I only wrote the truth. I said what you said but in a different way.”
What he had written was, “Today is a beautiful day and I cannot see it.”
Do you think the first sign and the second sign were saying the same thing?
Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the beauty of the day, but the boy could not enjoy it because he was blind.
The first sign simply said the boy was blind. The second sign told people they were so lucky that they were not blind.
⑥ 2015年6月四级仔细阅读关于防晒霜的原文和问题
防晒产品的选取标准
防晒产品的选择除了基本的紫外线波段防护力度之外，还应考虑到是否泛白以及满足相应肤质的肤感需求和合适的使用场景，不论多好的产品，在选择不正确的情况下，如果大部分时候你连涂都不想涂，那么防晒力度可以视作为0~~~~，另外皮肤若是相对敏感，具有一些如痘痘肌、皮肤过敏等症状则会在使用需求上追求更多的安全性，因此将防晒产品的选取标准用以下标准进行选择，在考虑到基本的防晒力度的同时，尽可能兼具舒适感。
非敏感型皮肤
健康肌肤因为对各种产品的适应性比较强，在使用过程中除了防晒力度之外，应该合理的考虑泛白程度、肤感是否清爽、是否兼具控油吸附效果。
a. 油皮：清爽之上更应兼具控油效果
b. 干皮：防止冬天拔干即可，肤感追求清爽
c. 混油皮：尤其是考虑到冬天U区略干，T区仍然略油，变化明显者可以选择两种防晒或者季节适用性比较强的防晒
敏感型皮肤
敏感肌肤容易对一些成分感到刺激，适合使用相对较温和安全的纯物理防晒，同时因为皮肤肤质差异对肤感有不同的要求，但不要太过于在意是否泛白，不严重就还好。
a. 油敏皮：选取纯物理防晒中较为清爽且适当兼具控油效果的防晒
b. 干敏皮：选取肤感比较清爽的纯物理防晒即可
c. 混合敏感皮: 不要挑剔太多, 觉得干, 油一点就将就用, 因人而异
注：细化分类只是为了满足精确查找，比如混油皮使用的防晒产品可以是另外两种肤质适用产品的重复，相对在季节舒适性上比较全面，而敏感肌的产品正常皮肤完全可以使用，甚至部分产品更好用，但是为了突出皮肤适用性特点，顾不在其中重复。
防晒产品推荐
A.非敏感型皮肤
a. 油皮
在相对健康的油皮中，针对皮肤全脸都比较油腻，甚至冬天都微微出油的情况下，选取以物化结合或纯物理防晒的粉体防晒产品控油。
