才转回来，没听说过pay an important part 啊，我估计是卷子印错了~你确认下呢，呵呵~

1、因为有的蛋白点难以切取出来，所以选择了容易切取的5个蛋白点。
Since it's difficult to cut off some protein spots, five easily cuttable spots are selected.
1）. protein spots 蛋白点
2）. 题意中只说了“选择”了“5个容易切取的蛋白点”，没有说把这五个切除了（虽然很可能是这个意思，但没有表明清楚），所以用 select.

2、另外两组的图片如下，因为我已经在其他杂志中发表过了，所以没有附上。
Another two groups of pictures are shown as below. They're not attached due to previous publishing on other magazines.

I havn't written my blog for a long while, now I am customed to hidding bad moods. I have got upset these days because I don't dare and am not willing to admit that I still miss you. I want to know how you are now and I want to tell you I really regret about missing you.

It has been long time sinc my last diary.

Keeping things deep in my heart has been my habite now.

The emotion becomes unaccountable.

That's because I'm afraid to and don't want admite that I still miss you so much...

Still want to know your news.

Still want to know whether you're fine now.

What I really want to tell is losting you makes me really regret.
