3 检验证明
3句英文任你选
We'll accept the goods only if the results from the two inspections are identical with each other.
如果双方的检测结果一致，我们就收货。
Who issues the inspection certificate in case the quality do not confirm to the contract?
如果货物的质量与合同不符，由谁出具检验证明书呢?
You may have another certificate showing the goods to be free from radioactive contamination.
你们还有出具另一份证明书，以证明货物没有收到放射物污染。

半个句型要记牢
only if ~(只有……才)

Tip:
在 only if这个短语中，副词only是中心词，而从属连接词 if则只是用来连接从句的，因此，它表示"只有……(才);只有在……的时候，唯一的条件是……"的意思。例如 I told him he would succeed only if he tried hard. (我告诉他，只有努力才能成功。), only if有时也写成。only...if，表示唯一的条件，但是意思不变。例如 I will only come home if you come with me. =I will come home only if you come with me. (只有你跟我一起走，我才回家。)该词组容易与 if only混淆， if only意思是"但愿"、"要是……该多好啊通常用来表示说话人对某事所寄予的某种强烈愿望，相当于 as long as 。
