It’s 3 pm. Time for news from the World of Medicine. Does sitting make you sad? Australian researchers found that middle-aged women who sat for over 7 hours a day were 47 percent more likely to show sense of depression than those who sat for 4 hours or fewer. Those who engaged in no physical activity were 26 percent more likely to have symptoms of depression 3 years later than those who exercise regularly. Sitting for long periods has also been linked to heart disease.
How can you detect a liar through a texted message? Watch for a delayed response. When college students were asked to tell a lie during an interview with a computer, they took10 percent longer on average to send a message and they did more editing than usual.
Can marriage beat cancer? Married people were 20 percent less likely to die from the disease than those who were unmarried, according to a Harvard study of more than 730,000 people. They were also more likely to get the disease detected at an earliest age and receive proper treatment. A husband or wife can urge you to seek medical help and support you during tough chemical therapy, radiation and other treatments.

【题目】七选五
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
(2017·新课标全国卷III)Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock. 1 Here’s how to make one.
● 2 In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reasons, tell your family or roommates about the change you want to make.
● Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 3 That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.
● Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. 4
● Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record. 5 If not, take another look at other methods you could try.
A. Get a sleep specialist.
B. Find the right motivation.
C. A better plan for sleep can help.
D. And consider setting a second alarm.
E. If the steps you take are working, keep it up.
F. Stick to your set bedtime and wake-up time, no matter the day.
G. Reconsider the 15 minutes you spend in line at the cafe to get coffee.

【题目】（9分）下列是利用小鼠所做的几个实验，请回答相关问题：
实验一 选择30只生理状况大致相同的健康成年小鼠，测定小鼠单位时间耗氧量的平均值，以代表小鼠的物质代谢强度，将其随机分为甲、乙两组，做如下处理：
组别 | 实验处理方法 | 实验结果 |
甲 | 切除小白鼠体内的甲状腺 | 切除10天后，测得其物质代谢强度大大下降 |
乙 | 切除小白鼠体内的甲状腺，5天后，连续给小白鼠注射一定量溶于某种溶剂中的甲状腺激素 | 切除10天后，测得其物质代谢强度没有下降 |
由此可以推测：甲状腺激素能增强__________________________。为了证明这一推论，要增加一对照实验，对照实验的处理方法是________________________________________。
实验二 已知卵巢分泌的雌性激素能促进子宫发育。研究人员为探究垂体分泌的促性腺激素对卵巢和子宫发育的影响情况，用一批幼鼠做了如下实验：
组别 | 手术/处理方法 | 相同条件下喂养一段时间后，卵巢的平均重量（mg） | 相同条件下喂养一段时间后，子宫平均重量（mg） |
1 | 不做处理 | 68 | 216 |
2 | A | 36 | 93 |
3 | 切除垂体，同时定期注射适量雌性激素 | 37 | 219 |
4 | 切除垂体，同时定期注射适量促性腺激素 | 66 | 219 |
请回答：
（1）实验所用的幼鼠性别应为____________________，且小鼠的生长发育状况和个体应大小相近，原因是________________________________________。
（2）表中A处的处理方法为________________________________________。
（3）从实验结果可以看出，促性腺激素只能影响____________________的发育，第三组实验结果产生的原因是________________________________________。
