Do Peru's potatoes have the right stuff？That's the question scientists will be asking in Lima next month，when a selection of potatoes will begin undergoing tests to determine whether they are fit to grow on Mars.
NASA，the US space agency，is conducting the pioneering experiment together with Lima's International Potato Center.
They will cultivate a hundred selected varieties in Mars-like conditions that could eventually pave the way for building a dome on the Red Planet for farming the vegetable.Of the selected candidates,40 are native to the Andes Mountains，conditioned to grow in different ecological zones，can stand sudden climate changes and reproduce in rocky areas.The other 60 are improved varieties，able to survive with little water and salt.They are also immune to viruses.Those that pass the tests must meet a final criterion—they must be able not only to grow well on Mars but also reproduce in large quantities.“We're almost 100 percent certain that many of the selected potato es will pass the tests，” said Julio Valdivia Silva，a Peruvian NASA astrobiologist (太空生物学家) who is taking part in the ambitious project.The scientists plan to transport 100 kilos of soil to a lab in Lima that will simulate the complex Martian atmosphere—which contains mostly carbon dioxide—and expose it to extreme ultraviolet (紫外线的) radiation.If the varieties selected for next month's experiment don't adapt to the desert soil，the researchers will introduce nutrients，which will be provided by radiation.
In future years，NASA plans to build a Mars research center in the Peruvian desert.It would create a perfect copy of the Martian landscape and atmosphere for future research into space farming that could serve manned missions to Mars and other planets in the solar system.

B．Many types of potatoes to be planted on Mars are developed in Peru.
C．Sixty varieties native to the Andes Mountains can stand sudden climate changes.
D．The final criterion is that all the candidates are immune to viruses on the earth.
3．What if the selected varieties don't adapt to the desert soil in Peru?
A．Astrobiologists will be sent there to help.
B．Nutrients will be provided to plants by radiation.
C．A Mars research center will be built for further study.
D．100 more kilos of potatoes will be directly sent to Lima.

Tips to Ease Migraines
If you've ever experienced migraine headache，you know that it's no walk in the park.Migraines are a very painful type of headache，and often felt on one or both sides of a head.Some people experience migraines every now and then，while others get them more than once a week.__1__Although they are not dangerous to life，migraines can seriously affect one's ability to function throughout the day.Here are four tips for easing migraines.
1.Learn to manage.Migraines are often caused by stress，so try not to get stressed out easily.Avoid using the computer for too long and going to bed late at night.Learning stress management techniques can reduce and even prevent the pain of a migraine headache.__2__If you prefer to practice relaxation
at home，then try lying down on your bed or sofa and closing your eyes.Take slow，deep breaths and focus on relaxing each muscle group one at a time until you feel relaxed every single muscle in your body.
2．Use ice massage (按摩)．Another solution is the “ice massage”．Put your fingers into ice-cold water and then press your temples (太阳穴 ) until the pain decreases.__3__
3．Drink lots and lots of water.You can also get migraines if your body lacks water.Avoid dehydration by staying out of the sun and drinking plenty of water throughout the day.Carry a water bottle with you.__4__
4．__5__When you have a migraine，lights and sound can sometimes be your worst enemy.Close your curtains，turn out the lights，and remember to turn off the TV.
A．Add a few drops of peppermint (薄荷) oil for an even stronger effect.
B．Create a dark space to rest.
C．But never drink coffee，tea，or soda，for these may cause migraines.
D．But never wear headphones for too long，since they may cause migraines.
E．Avoid bright lights and loud noises.
F．You can do this by taking a yoga lesson.
G．About 6 in every 100 people regularly experience migraine headaches.
答案：[解题导语]本文是一篇说明文。文章介绍了一些缓解偏头痛的方法。
1．G 解析：上文讲到了一些人饱受偏头痛的困扰，下文转换话题说尽管偏头痛不会危及生命，但是会影响生活。由此可知，设空处应该是对上文的延伸。G项内容是患病人数，与上文意义一致。故选G项。
2．F 解析：根据空格后的If you prefer to practice relaxation at home...可知，空格处的内容应是涉及放松方面的，而F项中的taking a yoga lesson正是放松的一种方式。故选F项。
3．A 解析：本段介绍的方法是冰按摩，而A项中的薄荷油也有类似的凉爽感觉。故选A项。
4．C 解析：本段介绍的方法是多喝水，选项应该与饮水相关，C项中的咖啡、茶水和苏打水与此相关，而且饮用这些东西会导致偏头痛。故选C项。
5．E 解析：空格后说到，当你患有偏头痛的时候，声音和光是你最大的敌人。因此空格处应该是避免强光和噪音。故选E项。
Ⅲ.语法填空
[2017·湖南东部六校联考]

答案：[解题导语]本文介绍了黑色星期五的由来。
1．frequently 解析：考查副词。句意：它频繁地被称作“黑色星期五”。空处修饰动词短语is referred to，应用副词。
2．to 解析：考查固定搭配。relate to... “和……有关”，是固定短语。
3．being 解析：考查动名词作主语。分析句子结构可知，本处应用动名词短语being“in the black”on the Friday after Thanksgiving作主语。
4．to get 解析：考查非谓语动词。它给顾客一个以惊人的价格获得商品的机会。本处应用动词不定式作an opportunity的定语。
5．and 解析：考查并列连词。多数的商家都会早早地开门迎客，同时为顾客提供很多吸引人的折扣。本处and连接两个并列的谓语。
6．an 解析：考查冠词。an early start“一个早的开始”，此处表示泛指，故应用不定冠词；又因early 的读音以元音音素开头，故用an。
7．which 解析：考查定语从句。分析句子结构可知，本处应为非限制性定语从句，空处指代前面的“people face crowded stores”这句话，应用关系代词which。
8．busiest 解析：考查形容词最高级。它过去常常是一年中最繁忙的购物日。根据前面的the可知，本处应用最高级busiest。
9．involved 解析：考查非谓语动词。很多人避免在这一天购物，因为会卷入嘈杂人群的压力中。involve 与stress为逻辑上的动宾关系，故用过去分词作定语。
10．has seen 解析：考查时态和主谓一致。根据时间状语In recent years可知，本处应用现在完成时，主语the Saturday before Christmas为单数，故用has seen。
Ⅳ.短文改错

限时训练 一、阅读下面的文字，完成1～3题。(14分) 把往事调成花色 王健 很多日子是随阳光一起开放的，很多心情也是随花朵一起明媚的。 闲暇的时候，我总喜欢一个人背着相机来往于城市和乡村之间。在一个乡村古老的街道上，我看到了一堵石墙上花开烂漫，眼前一亮，我知道那将会是一个写满故事的小院。 主人是一个戴着眼镜的老者，正用放大镜认真地看着报纸，他坐在门口，A身体有些蜷曲，像棵老藤。很难相信，在这样的村庄里会有这么一个学者一样的老人。他的文雅、淡然，安静和自若的神态，让我感觉他和这些花、这个小院就是一个密不可分的整体。 耳聋，面善，和蔼可亲，很善谈，他生活在自己沉静的世界里，却出现在我的视野中。通过那些花，我知道了他是个95岁高龄的老人，以前做过教师。难怪他身上有股与众不同的味道呢！ 他告诉我，墙头上这些艳丽的花是凌霄，已经有几十年的历史了，去年有人想花1 000元买走，他没舍得。他继而又补充道，如果多点儿我就卖掉它，卖些钱好给老伴治病。 数落起这些花就好像数落着自己的子女。这些是兰，这些是莲，这是栀子，这是何首乌……我突然就想起鲁迅先生笔下的百草园，诗情画意里有一段美丽的故事。 然后他便开始数落那些子女，仿佛在数落着自己院里的那些花草。 我很想从这个高寿的老人口中知道幸福的定义。我问幸福是什么，他听不清：什么？ 后来他告诉我幸福是“什么”。
我没懂，他笑：什么都是幸福。小时候想上学堂，以为那就是幸福，后来就去了。后来想当教员，以为那就是幸福，后来真就当了教员。退休了，想安养晚年就是幸福，于是有了这满院花香相伴。现在有人能欣赏我的这些花，我也很幸福。 那么你幸福吗？他回答，我满足于我人生的任何一件事情，无论成败得失。就像我养的这些花，花开花谢，它们不会长开不败，却能在最美的时候开放…… 终于明白一个无私、无欲的老人的幸福观。能够像他院中的花一样，顺从自然、与世无争、坦然处世，就是一种美丽和幸福。 他，何尝不是开在这尘世间的一朵浮莲，B甚至是一棵开满花朵的老藤？ 他把我当作客人，我把这里当作我内心的家园，仿佛一杯茶汁泼出的茶园，至今梦里尚带几分茉莉香。而且他的花香弥漫的脸，是媚人的，沧桑中写着“生活”两个字。如果你仔细地去读，会读出更多的内容。 赏过凌霄，闻过芝香，也饮过菊花，愿意在这远离世俗的地方喝醉。感觉阳光、童年、往事和爱，还闪亮在老屋的深处，只是感觉偶尔等一个人，是偶然的缘分。在多年后，10年或者20年时给它浇水，叶年年青翠，花年年明艳，而眼睛却暗了…… 人生莫过于此：头发掉了，牙齿没了，眼睛花了，耳朵聋了，内心却十分明亮。如今，往事皆调成这满院的花色，花开了，年年更新，心就是不老的，还有爱和希望，快乐和幸福。 我突然看到那暗淡的老屋里，窗台上竟然摆放着一瓶栀子花！一个年迈老人对生活之爱，远远浓于这满院的花香，我要告诉你那是心香呵！是生命之香！ 我独自走在乡间，一位蜷曲的老人，一座破旧的老屋，一些美丽的花，美好的事物走在我的前面，我记得那老人的话：“我要把我的那些花安放在冬天的前面……”

英语试题 第二部阅读理解(共两节，满分40分) 第一节(共15题;每小题2分，满分30分) 阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项，并在答题卡上将该项涂黑。 A Summer Activities Students should read the list with their parents/carers, and select two activities they would like to do. Forms will be available in school and online for them to indicate their choices and return to school. Before choices are finalised, parents/ carers will be asked to sign to confirm their children’s choices.
21. Which activity will you choose if you want to go camping? A. OUT. B. WBP. C. CRF. D.POT. 22. What will the students do on Tuesday with Mrs. Wilson? A. Travel to London B. see a parade and fireworks. C. Tour central Paris. D. Visit the WWI battlefields. 23. How long does Potty about Potter last? A. Two days. B. Four days C. Five days D. One week. B Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colorful and sweet jewels from British Columbia’s fields are little powerhouses of nutritional protection. Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein(蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into Vitamin A and which are antioxidants. As for cherries(樱桃), they are so delicious who care? However, they are rich in Vitamin C. When combined with berries or slices of other fruits, frozen bananas make an excellent base for thick, cooling fruits shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.
阶段示范性金考卷(九) (教师用书独具) 本卷测试内容：电磁感应 本试卷分为第Ⅰ卷(选择题)和第Ⅱ卷(非选择题)两部分，共110分． 第Ⅰ卷(选择题，共60分) 一、选择题(本题共12小题，每小题5分，共60分．在第1、2、4、5、7、8小题给出的4个选项中，只有一个选项正确；在第3、6、9、10、11、12小题给出的四个选项中，有多个选项正确，全部选对的得5分，选对但不全的得3分，有选错的得0分．) 1. [2018·济南高三模拟]如图所示，一轻质横杆两侧各固定一金属环，横杆可绕中心点自由转动，拿一条形磁铁插向其中一个小环，后又取出插向另一个小环，发生的现象是( ) A. 磁铁插向左环，横杆发生转动 B. 磁铁插向右环，横杆发生转动 C. 无论磁铁插向左环还是右环，横杆都不发生转动 D. 无论磁铁插向左环还是右环，横杆都发生转动 解析：本题考查电磁感应现象、安培力的简单应用．磁铁插向左环，横杆不发生移动，因为左环不闭合，不能产生感应电流，不受安培力的作用；磁铁插向右环，横杆发生移动，因为右环闭合，能产生感应电流，在磁场中受到安培力的作用，选项B正确．本题难度易． 答案：B 2. 如图所示，在某中学实验室的水平桌面上，放置一正方形闭合导体线圈abcd，线圈的ab边沿南北方向，ad边沿东西方向，已知该处地磁场的竖直分量向下．下列说法中正确的是( ) A. 若使线圈向东平动，则b点的电势比a点的电势低 B. 若使线圈向北平动，则a点的电势比d点的电势低 C. 若以ab为轴将线圈向上翻转，则线圈中感应电流方向为abcda D. 若以ab为轴将线圈向上翻转，则线圈中感应电流方向为adcba 解析：由右手定则知，若使线圈向东平动，线圈的ab边和cd边切割磁感线，c(b)点电势高于d(a)点电势，故A错误；同理知B错误；若以ab为轴将线圈向上翻转，穿过线圈平面的磁通量将变小，由楞次定律可判定线圈中感应电流方向为abcda，C正确．
