问题 单项选择题 A1/A2型题

若凝块稳定性试验阳性需进一步做证实试验,对证实试验说法正确的是()。

A.测定酶的活性和蛋白质浓度

B.对第因子缺乏分型

C.采用对患者纤维蛋白凝块用放射标记胺类物质渗入蛋白质(如酪蛋白)的方法、免疫化学方法和扫描以定量γ-和α-链的交联形成

D.也用于测定治疗制品在体内的半衰期以帮助治疗

E.以上说法都对

答案

参考答案:E

解析:进一步应做证实试验测定酶的活性和蛋白质浓度,并对第因子缺乏分型。可对患者纤维蛋白凝块用放射标记胺类物质渗入蛋白质(如酪蛋白)的方法、免疫化学方法和扫描以定量γ-和α-链的交联形成。这些方法精确敏感,也用于测定治疗制品在体内的半衰期以帮助治疗。

信息匹配 

阅读下列材料,从所给的六个选项(A、B、C、D、E、F)中,选出符合各小题要求的最佳选项。选项中有一项是多余选项。

首先,请阅读以下某理财论坛提供的几条省钱建议:

A

Use cash. Instead of paying things with credit cards, use cash for non-bill spending such as eating out, gas and groceries. Spending cash makes the spending more real, and there’s an added advantage of knowing when you’re out of cash.

B

Small weekly savings transfers. I got this idea from my friend, who automatically deducts(扣除) $20 a week from his check to savings. I decided that I could live with the deduction of $40/week without really feeling it — it’s a relatively small transfer that I barely notice, and I save about $2,000 a year!

C

Stay at home. Going out makes you spend money unnecessarily. You eat at restaurants, go to the mall, and stop at the gas station for snacks. It’s hard to avoid spending when you’re on the road. Instead, stay at home and find free entertainment. It’s also a great way to bond with your family.

D

Don’t get catalogs(商品宣传册). Their announcements of sales or cool new products make it very tempting(引诱人的) to buy something you don’t need. Instead, stop getting the catalogs, and you’ll spend less.

E

Keep a 30-day list. If you have an impulse(冲动) to buy something you don’t absolutely need, put it on a 30-day list. You can’t buy anything but necessities — everything else goes on the list. When the 30 days are up, you can buy it — but most likely, the strong urge to buy it will be gone, and you can evaluate it more calmly.

F

Cook at home. I know it seems more difficult than eating out. But it doesn’t have to be hard. Make home-made pizza with a ready-made crust, some sauce, cheese and veggies. Put some spices on something and throw it in the oven while you cook some brown rice. Not only is this much cheaper than eating out, but it’s healthier.

阅读下面几位消费者的情况介绍,并为他们匹配合适的建议。

1. Mr. And Mrs. Brown are a newly-married couple who work in the same company. They don’t earn much in their work, but they have to spend a larger part of their income to pay for their rent and daily necessities. Furthermore, they seldom eat at home because neither of them cooks well. Therefore, they have to pay a lot more extra money for food.

2. Mrs. Wang enjoys shopping very much because she is free all day long. Whenever she is wandering in the shops or stores, she will have a strong impulse and find it difficult for her to get back home with her hands empty. But it is quite often that she will find what she has bought is almost useless when she gets home.

3. Tony is a university student in New York, who is far away from his parents. He pays everything with his credit card. He finds it very cool for him to purchase with his credit card. However, he often finds his money has already run out in the middle of the month.

4. Miss Betty is a high school girl whose parents give her some money every week. As her parents don’t earn much money, she wants to save some money secretly so that she can buy a digital camera.

5. Miss Catherine is a young girl who is easily to be persuaded into buying something useless. She will get encouraged to buy something when she sees an advertisement. Her parents have warned her many times against doing such stupid things, but it doesn’t work much.
