5. The trademark pattern of the commodity is as shown in the figure (shaded part). It is known that the side length of diamond ABCD is 4. A=60？ The arc BD is an arc with a center a and a radius AB, and the arc CD is an arc with a center b and a radius BC. What is the area of the logo? ()

6. A young woman was accompanied by her family to the hospital because of severe nausea and abdominal pain. The doctor suspected that it was ectopic pregnancy after examination, and suggested to transfer to obstetrics and gynecology. However, the patient's family insisted that the girl was unmarried and could not get pregnant. What should the doctor do at this time? ()

D. Ask the patient's family members to sign the consent form of refusing referral, give hemostasis and analgesia treatment, and stay in hospital for observation.

Reference answer and analysis

1. Reference answer D. Analysis: (1) This question examines the knowledge points of physiology-endocrine-endocrine glands. (2) Endocrine glands include pituitary gland, thyroid gland, parathyroid gland, islet, adrenal gland and gonad. Heart, liver, kidney, stomach and other organs do not belong to endocrine glands. (So ABC is wrong, choose D).

2. Reference answer A. Analysis: By connecting OC, OD and CD, CD//AB can be obtained, so △ACD and △OCD have the same height, and the area of △ACD = the area of △ OCD, so the area of shadow part can be converted into the area of fan-shaped OCD. Because AB= 12cm, the radius of the semicircle is 6cm, because C and D are bisectors of this semicircle, so? COD=60？ ,

3. Reference answer C. Analysis: If the workload is 90, A's work efficiency is 3 and B's work efficiency is 5. 12 days b made 5? 12=60 workload, then A did 90-60=30, then A did 30? 3= 10 days.

4. Reference answer A. Analysis: Because the number of people who can only know one kind+at least two kinds+the number of people who can't know three kinds =55, the number of people who can only know one kind = 55-19-4 = 32; If there are x people in three metropolises, there are 23+24+29- 19-x+4=55, and x=6 people; Then there are 32-6=26 people who can't know any of them. Choose A.

5. Reference answer B. Analysis: By connecting BD, the area of shadow is equal to the area of △BDC, so this question only needs the area of △BDC. Because? A=60？ , so? C=60？ So △BDC is an equilateral triangle with side length =4.

6. Reference answer C. Analysis: Ectopic pregnancy is a very serious situation. The patient has abdominal pain, but the patient and his family have always said that they are not pregnant and refused to refer. Therefore, it is necessary for doctors to explain the seriousness of ectopic pregnancy to their mothers and invite obstetricians and gynecologists to consult and make a diagnosis as soon as possible to avoid danger, so the answer is C.
